Description: The purpose of this dissertation was twofold. First, the study sought to determine if the Texas Academic Skills Program (TASP) Reading score predicts success on the Examination for the Certification of Educators in Texas (ExCET). Second, the study addressed the effect on individuals of color of raising the minimum TASP Reading score entrance requirement for admission to teacher preparation programs. Data were collected from the ExCET Office of a Carnegie I metropolitan university. The defined sample consisted of 961 participants who had a TASP Reading score and had taken an Elementary Comprehensive ExCET, an Elementary Professional Development ExCET or a Secondary Professional ExCET between September 1999 and January 2001. Linear Regression, Box Test, Predictive Discriminate Analysis, and frequency distribution tables were used for analyses. This investigation examined the effects of the independent variable of TASP Reading score on the performance of participants on the dependent variable, the ExCET. Four null hypotheses were tested at the .05 level of significance. The TASP Reading score was a statistically significant predictor for success on the Elementary Comprehensive ExCET, Elementary Professional Development ExCET, and the Secondary Professional Development ExCET. However, the Predictive Discriminate Analysis indicated that a TASP Reading score of 220 predicted that ...

The uninvestigated factors: Dimensions of personality and psychopathology in sex offenders

The uninvestigated factors: Dimensions of personality and psychopathology in sex offenders

Date: May 2001
Creator: Briley, Josh
Description: Understanding the relation between personality characteristics, psychopathology, and sexual offenses can contribute to developing more effective treatment interventions. Previous research with sex offenders has focused on general personality traits or inconsistently classified sex offenders based on psychopathology. It was hypothesized that combining personality and psychopathological traits can assist in understanding sex offenders. The current study evaluated 88 male sex offenders in a court-mandated outpatient treatment program utilizing the NEO-PI-R and the MMPI-2. Three clusters of child molesters were examined for differences in personality characteristics and number of offenses. A second-order principle axis factor (PAF) analysis of personality and psychopathology traits revealed three factors: Psychological Distress, Excitement-Seeking, and Social Desirability. The potential clinical utility of these dimensions in predicting treatment compliance is examined.

Unique applications of cultured neuronal networks in pharmacology, toxicology, and basic neuroscience

Unique applications of cultured neuronal networks in pharmacology, toxicology, and basic neuroscience

Date: May 2001
Creator: Keefer, Edward W.
Description: This dissertation research explored the capabilities of neuronal networks grown on substrate integrated microelectrode arrays in vitro with emphasis on utilizing such preparations in three specific application domains: pharmacology and drug development, biosensors and neurotoxicology, and the study of burst and synaptic mechanisms. Chapter 1 details the testing of seven novel AChE inhibitors, demonstrating that neuronal networks rapidly detect small molecular differences in closely related compounds, and reveal information about their probable physiological effects that are not attainable through biochemical characterization alone. Chapter 2 shows how neuronal networks may be used to classify and characterize an unknown compound. The compound, trimethylol propane phosphate (TMPP) elicited changes in network activity that resembled those induced by bicuculline, a known epileptogenic. Further work determined that TMPP produces its effects on network activity through a competitive inhibition of the GABAA receptor. This demonstrates that neuronal networks can provide rapid, reliable warning of the presence of toxic substances, and from the manner in which the spontaneous activity changes provide information on the class of compound present and its potential physiological effects. Additional simple pharmacological tests can provide valuable information on primary mechanisms involved in the altered neuronal network responses. Chapter 3 explores the effects produced ...

University Students and the Internet: Information Seeking Study

University Students and the Internet: Information Seeking Study

Access: Use of this item is restricted to the UNT Community.
Date: May 2001
Creator: Shamo, Esmaeel
Description: This study explored university students' information needs and seeking behaviors on the Internet. A Web-based survey was administrated one time. Two hundred responses were received from the target sample within the two weeks period of the study. Data were analyzed with descriptive statistics, factor analysis, and graphical representation. The study explored various issues related to the usability, preferences, and activities of the Internet, such as searching tools, e-mail, search engines, and preferred primary sources of everyday-life information needs. The study explored the perceptions of the students toward the Internet and the traditional library. Kuhlthau's model of the information-seeking process, which includes six stages and affective components, was utilized and modified in the construction of the Web survey. A study by Presno (1998), which includes the four types of Internet anxiety, was utilized in the construction of the Web survey. With regard to the six stages of Kuhlthau model, the majority of the respondents experienced stage 5, which was about information gathering; stage 3 had the next highest number of respondents. Very few respondents experienced stages 1 and 2. There was a systematic pattern in which, the earlier the stages the respondents were in, the more negative adjectives they selected, and ...

Use of GIS to Identify and Delineate Areas of Fluoride, Sulfate, Chloride, and Nitrate Levels in the Woodbine Aquifer, North Central Texas, in the 1950s, 1960s, 1970s, 1980s, and 1990s

Use of GIS to Identify and Delineate Areas of Fluoride, Sulfate, Chloride, and Nitrate Levels in the Woodbine Aquifer, North Central Texas, in the 1950s, 1960s, 1970s, 1980s, and 1990s

Date: August 2001
Creator: Sanmanee, Sirichai
Description: ArcView and ArcInfo were used to identify and delineate areas contaminated by fluoride, sulfate, chloride, and nitrate in the Woodbine Aquifer. Water analysis data were obtained from the TWDB from the 1950s to 1990s covering 9 counties. 1990s land use data were obtained to determine the relationship with each contaminant. Spearman's rank correlation coefficients and Kruskal-Wallis tests were used to calculate relationships between variables. Land uses had little effect on distributions of contaminants. Sulfate and fluoride levels were most problematic in the aquifer. Depth and lithology controlled the distributions of each contaminant. Nitrate patterns were controlled mainly by land use rather than geology, but were below the maximum contaminant level. In general, contaminant concentrations have decreased since the 1950s.

The use of notated and aural exercises as pedagogical procedures intended to develop harmonic accuracy among beginning jazz improvisers

The use of notated and aural exercises as pedagogical procedures intended to develop harmonic accuracy among beginning jazz improvisers

Date: August 2001
Creator: Laughlin, James Edwin
Description: This study compared the effects from the use of aural and notated exercises as pedagogical procedures for teaching harmonic accuracy to beginning jazz improvisation students. The methods of pedagogy were identified from published pedagogic and historical sources, the results of oral and written traditions of jazz pedagogy. The performance objective was produced from a review of the related literature as a recognized and measurable characteristic of jazz improvisation. The purpose of this study was to compare measurements of harmonic accuracy, following the use of notated and aural exercises as experimental procedures of jazz improvisation pedagogy. A lesson plan, materials, curriculum and outline were developed followed by student recruitment and participation. A total of 20 student volunteers participated in the methods of pedagogy (aural or notation). Data collection consisted of a musical background questionnaire and pre and posttest performance recordings. Student recordings were evaluated by six judges using the “experimental performance evaluation measure.” Statistical analyses were conducted, including comparisons of pre to posttest effects between, and among the methods of pedagogy. Although all student participants performed mostly from notated music prior to this study, students who received the aural method of pedagogy produced greater improvement for all measurement items. While the ...

Variations of the Hand Test with young and older adults

Variations of the Hand Test with young and older adults

Access: Use of this item is restricted to the UNT Community.
Date: August 2001
Creator: Radika, Lisa M.
Description: To explore the influence that variations in projective stimuli might have on the respondent's ability to identify with pictorial representations of hands derived from the Hand Test (Wagner, 1961, 1983), 61 young adults (M age = 23) and 60 older adults (M age = 73) were presented with four alternate versions of hand stimuli (young male, young female, old male, and old female) in addition to the original Hand Test. Results indicated main effects for age and gender of respondent, which were primarily consistent with previous Hand Test research. Main effects for gender and age of hand stimuli (p < .05) were also found. Significant interaction effects were revealed for age of respondent by age of hand stimuli and for age of respondent by gender of hand stimuli (p < .05). These interactions resulted in the elicitation of a variety of responses to a differentiated manner than a standard set of Hand Test stimuli. A gender of respondent by gender of hand stimuli interaction effect was also found (p &lt; .05), suggesting that gender alterations of the card may also be beneficial for increasing respondent identification for some individuals. Overall, the results of variations in Hand Test stimuli, as they ...

Virtual Teams and Technology: The Relationship between Training and Team Effectiveness

Virtual Teams and Technology: The Relationship between Training and Team Effectiveness

Date: May 2001
Creator: Andrews, Angelique
Description: The impact of training on virtual team effectiveness was assessed in five areas: communication, planning tasks and setting goals, solving problems and making decisions, resolving conflict, and responding to customer requirements. A 12-page survey was developed exploring all aspects of virtual teams. 180 surveys were distributed, 52 were returned representing 43 companies. Training led to higher effectiveness in planning tasks and setting goals, solving problems and making decisions, and conflict resolution, but not in communication and responding to customer requirements. Training may not solve all the problems that virtual teams will encounter; however, training will make the challenges easier to handle.

Virtual teams: The relationship between organizational support systems and effectiveness

Virtual teams: The relationship between organizational support systems and effectiveness

Date: May 2001
Creator: Townsley, Carole
Description: This study investigates the effects of eight organizational support systems on virtual team effectiveness in five areas: communication, planning tasks and setting goals, solving problems and making decisions, resolving conflict, and responding to customer requirements. One hundred and eighty surveys were sent to information technology managers and collaborative team members, representing 43 companies. The results indicated that developing new roles for IT professionals and senior managers significantly increased virtual team effectiveness in several areas. The findings support the theory that organizations that utilize virtual teams must create high-level structures, policies, and systems to support the teams and the information tools they use.

Where I am From, Finding My Identity Through Visualizing Memories

Where I am From, Finding My Identity Through Visualizing Memories

Date: August 2001
Creator: Itoi, Jun
Description: This article discusses about the author’s identity related to the experience of being in the United States for one third of his life, and away from his native country, Japan. He uses photographic images as a tool for finding his identity. Those images are combined and painted with paraffin wax as finished pieces. The extra layer of wax on the photographic surface is treated as a metaphor for the fuzziness of memories and dreams, as well as a boundary, which lies between author’s two familiar spaces, the United States and Japan. His visual influences are shown to include photographer Henri Cartier- Bresson, painter Giorgio de Chirico, and sculptor Alberto Giacometti.
