Police officers: Perception of self, occupational role, and occupational events.

Police officers: Perception of self, occupational role, and occupational events.

Date: December 2003
Creator: Piper, Lynn J.
Description: This study examined police officers' perceptions of self, occupational role and their relation to perceived stress and posttraumatic stress symptomology. Self-report measures for the study variables were completed by 101 police officers. Hypotheses predicted that perception of self and role would be associated with perception of stress and that perception of the stress would mediate PTSD symptomology. Neuroticism, job quality and general job satisfaction were the main predictors of stress. Stress levels mediated between 1) job quality and the symptoms of anxious arousal and impaired self-reference; 2) general job satisfaction and the symptoms of defensive avoidance and dissociation; and 3) neuroticism and the symptom of defensive avoidance. This implies that police officers' job quality, their feelings of general job satisfaction, and low levels of neuroticism are important in alleviating stress and subsequent psychological sequela.

Polymer Gels: Kinetics, Dynamics Studies and Their Applications as Biomaterials

Polymer Gels: Kinetics, Dynamics Studies and Their Applications as Biomaterials

Date: December 2003
Creator: Wang, Changjie
Description: The polymer gels especially hydrogels have a very special structure and useful features such as unusual volume phase transition, compatibility with biological systems, and sensitivity to environmental stimuli (temperature, pH value, electric field, light and more), which lead to many potential applications in physical and biochemical fields. This research includes: (1) the theoretical and experimental studies of polymer gels on swelling kinetics, spinodal decomposition, and solution convection in gel matrix; (2) applications of polymer gels in wound dressing, tissue-simulating optical phantom and gel display. The kinetics of gel swelling has been theoretically analyzed by considering coupled motions of both solvent and polymer network. Analytical solutions of the solvent and the network movement are derived from collective diffusion equations for a long cylindrical and a large disk gel. Kinetics of spinodal decomposition of N-isopropylacrylamide (NIPA) polymer gel is investigated using turbidity and ultrasonic techniques. By probing movement of domains, a possible time-dependent gel structure in the spinodal decomposition region is presented. Theoretical studies of solution convection in gel matrix have been done and more analysis on dimensionless parameters is provided. To enhance the drug uptake and release capacity of silicone rubber (SR), NIPA hydrogel particles have been incorporated into a SR ...

Presidents' Leadership Behaviors Associated with Followers' Job Satisfaction, Motivation Toward Extra Effort, and Presidential Effecitveness at Evangelical Colleges and Universities

Presidents' Leadership Behaviors Associated with Followers' Job Satisfaction, Motivation Toward Extra Effort, and Presidential Effecitveness at Evangelical Colleges and Universities

Date: December 2003
Creator: Webb, Kerry S.
Description: Transformational leaders have tendencies that include: 1) projecting confidence and optimism about goals and followers' ability, 2) providing a clear vision, 3) encouraging creativity through empowerment and rewarding experimentation, 4) setting high expectations and creating a supportive environment, and 5) establishing personal relationships with followers. Transactional leadership as a process in which leaders and followers decide on goals and how to achieve them through a mutual exchange. The leader provides followers with resources, rewards, and punishment in order to achieve motivation, productivity, and effective task accomplishment. Laissez-faire leadership is the process of letting followers work without direction or guidance from the leader. The laissez-faire leader avoids providing direction and support, shows a lack of active involvement in follower activity, and abdicates responsibilities by maintaining a line of separation between the leader and the followers. The primary purpose of this study was to investigate the assumption that a combination of transformational and transactional leadership factors is more predictive of greater followers' job satisfaction, motivation toward extra effort, and perceived presidential effectiveness than either leadership style alone. The study investigated perceptions of the degree to which transformational leadership, transactional leadership, and laissez-faire leadership were practiced by presidents of member colleges and universities ...

Priorities of the Professoriate in Historically Black Private Colleges and Universities

Priorities of the Professoriate in Historically Black Private Colleges and Universities

Access: Use of this item is restricted to the UNT Community.
Date: December 2003
Creator: Thornton, Artist
Description: The intent of the study was to ascertain the importance faculty at Historically Black Private Colleges and Universities in Texas place upon academic activities of research, teaching and service. A survey of faculty at 4 historically black private colleges and universities in Texas (HBCUs) was conducted to collect data from 158 faculty members; 107 usable questionnaires were returned. A response rate of 67.7 percent was achieved. The pattern that emerged from the data indicates the HBCU faculty in this study lean toward teaching and service as being a viable measure for tenure and promotion. The HBCU faculty in this study should remain cognizant that they are an intricate element within the higher education discipline. According to the perceptions of the HBCU faculty, several indicated that their college/university is important; however, they indicated that their academic discipline is less important in comparison. According to the perceptions of the HBCU faculty, many respondents indicated that their job is a source of considerable personal strain. A comparison with the findings of the 1989 Carnegie Foundation for the Advancement of Teaching reveals more similarities than differences.

The Public Polemics of Baldur von Schirach: A Study of National Socialist Rhetoric and Aesthetics, 1922-1945

The Public Polemics of Baldur von Schirach: A Study of National Socialist Rhetoric and Aesthetics, 1922-1945

Access: Use of this item is restricted to the UNT Community.
Date: December 2003
Creator: Koontz, Christopher N.
Description: This dissertation examines the political writings and speeches of Baldur von Schirach, a leading figure of the National Socialist German Worker's Party, and the means by which he chose to transmit his beliefs in totalitarianism, racism, and militarism. Schirach's activities serve as a case study of the Third Reich's artistic and cultural programs and the means by which these programs served as conduits for propaganda and public education. Throughout his career as the leader of the National Socialist Student's League, Reich Youth Leader, and Gauleiter of Vienna, Schirach promulgated a political theory which interpreted the rise of the Third Reich as an expression of an innately superior German culture. He put this theory forth through the use of artistic means, including his own poetry and prose, and theoretical exegeses of artistic and literary works that explained them within a fascist, totalitarian idiom. The dissertation discusses Schirach's personal adherence to Nazism and its roots; the ways in which he interpreted fascist philosophical tenets, symbols, messages, and archetypes; his concepts of youth and adult education; his attempts to mold the artistic community of Vienna into an aesthetically progressive, yet politically coherent, means of propaganda; and his role in the destruction of the ...

Pyrimidine Genes in  Pseudomonas Species

Pyrimidine Genes in Pseudomonas Species

Date: December 2003
Creator: Roush, Wendy A.
Description: This thesis is a comparative study of gene arrangements in Pseudomonas species, and is organized into three major sections. The first section compares gene arrangements for different pathways in Pseudomonas aeruginosa PAO1 to determine if the gene arrangements are similar to previous studies. It also serves as a reference for pyrimidine gene arrangements in P. aeruginosa. The second part compares the physical, and genetic maps of P. aeruginosa PAO1 with the genome sequence. The final section compares pyrimidine gene arrangements in three species of Pseudomonas. Pyrimidine biosynthesis and salvage genes will be aligned for P. aeruginosa PAO1, P. putida KT2440, and P. syringae DC3000. The whole study will gives insight into gene patterns in Pseudomonas, with a focus on pyrimidine genes.

QEEG and MMPI-2 patterns of adults reporting childhood sexual abuse: Determining differences and predictor models.

QEEG and MMPI-2 patterns of adults reporting childhood sexual abuse: Determining differences and predictor models.

Date: December 2003
Creator: Townsend, Alicia
Description: Childhood sexual abuse (CSA) has been linked to a number of adult psychological maladies. The MMPI-2 has shown specific patterns such as an inverted V in the validity scales, a floating profile, and a 4-5-6 configuration to be present more often in adults who have experienced childhood trauma. Both children and adults who have experienced trauma have shown a number of neurophysiological differences when compared to non-traumatized individuals. However, little research has looked at differences in quantitative electroencephalography (QEEG) patterns in these individuals. The purpose of this study is to determine differences seen in the MMPI-2 and the QEEG when comparing adults who report CSA to adults who deny any history of childhood abuse. Differences between the two groups in MMPI-2 basic scales and supplementary scales PK and PS were determined. This study also examined the ability to correctly classify individuals into the two groups using three patterns seen in the MMPI-2 basic scale profiles (inverted V, floating profile, and 4-5-6 configuration). In addition, this research included exploratory analyses to develop predictor models for CSA group membership. Predictors in the models were derived from MMPI-2 scales, alpha relative power at each of the 19 sites in the International 10/20 electrode ...

A qualitative analysis of the negative symptoms of schizophrenia interfering with academic and social success, and the exacerbators and diminishers of those symptoms.

A qualitative analysis of the negative symptoms of schizophrenia interfering with academic and social success, and the exacerbators and diminishers of those symptoms.

Date: December 2003
Creator: Flint, Paula J.
Description: The Individuals with Disabilities Education Act (IDEA) mandates that public schools provide appropriate school programs and transition services for students with emotional and behavioral disorders (E/BD), and the law specifically names schizophrenia as a disability for which services are to be provided. To date, little, if any, research has been conducted on schizophrenia in the field of special education. New antipsychotic medications for schizophrenia are controlling the positive symptoms of hallucinations, illusions, and the severest of delusions, thus enabling these students to remain in school. However, many interfering negative symptoms remain (e.g., loss of goals, loss of former interests, cognitive regression). The purpose of this qualitative research study was to identify the negative symptoms of schizophrenia that interfere with a student's academic and social success, primarily within a school setting, but also as they affect functioning within the family and the student's transition into the community. In addition, specific factors that act as exacerbators or diminishers of these symptoms were identified through this study. Research participants included 5 students who developed schizophrenia from the ages of 12 to 22, their parents, and their teachers. They were interviewed using a semi-structured approach resulting in over 30 hours of taped interview data. ...

Refactoring FrameNet for Efficient Relational Queries

Refactoring FrameNet for Efficient Relational Queries

Date: December 2003
Creator: Ahmad, Zeeshan Asim
Description: The FrameNet database is being used in a variety of NLP research and applications such as word sense disambiguation, machine translation, information extraction and question answering. The database is currently available in XML format. The XML database though a wholesome way of distributing data in its entireness, is not practical for use unless converted to a more application friendly database. In light of this we have successfully converted the XML database to a relational MySQL™ database. This conversion reduced the amount of data storage amount to less than half. Most importantly the new database enables us to perform fast complex querying and facilitates use by applications and research. We show the steps taken to ensure relational integrity of the data during the refactoring process and a simple demo application demonstrating ease of use.

The relationship between the reasons for participation in continuing professional education and the leader effectiveness of first-line supervisors.

The relationship between the reasons for participation in continuing professional education and the leader effectiveness of first-line supervisors.

Access: Use of this item is restricted to the UNT Community.
Date: December 2003
Creator: McCamey, Randy B.
Description: This research examined the reasons for participation in continuing professional education (CPE) and the predictive relationship of those motivational reasons to the perceived leadership effectiveness of first-line supervisors. For this study, 105 first-line supervisors were surveyed from four electric utility companies. Input was also collected from each supervisor's subordinate employees. Using the five motivational reasons for participation, collected via the Participation Reasons Scale and the effectiveness score collected using the Leader Behavior Analysis II®, regression techniques were used to asses the data. The five participation reasons of the PRS were regressed individually against the effectiveness scores to determine the extent to which leader effectiveness could be predicted by the participation reasons. In each case, the null hypothesis failed to be rejected. Regression of the five PRS reasons collectively on leader effectiveness also failed to reject the null, producing a p value of .800 and an R2 value of .023. An "all possible subsets" regression was conducted to determine whether a smaller subset of the five predictor variables might improve the predictive value of the participation reasons. No subset improved the predictive value. This study concludes that motivation to participate in CPE does not predict leader effectiveness. Thus, training organizations do ...
