Participation in a study-abroad program and persistence at a liberal arts university.

Participation in a study-abroad program and persistence at a liberal arts university.

Date: December 2003
Creator: Young, Denise York
Description: This study used a quasi-experimental design with 1,237 students to investigate the association between participation in a study-abroad program and persistence at a liberal arts university. The theoretical basis for the study was Tinto's Theory of Individual Departure. The independent variable of interest, also known as the treatment, was participation in the University of Dallas Rome Program during the sophomore year. The control group consisted of students who were qualified to participate in the Rome Program, but chose not to do so. The dependent variable was the number of fall and spring semesters enrolled as an undergraduate at the University of Dallas post-treatment through spring 2003. Nine variables that measured background characteristics, academic integration, and social integration explained 3.8% of the variation in number of semesters enrolled post-treatment. Participation in the Rome Program explained an additional 4.2%. In all of the statistical measures examined in this study (incremental increase in R2, b weights, adjusted β weights, and structure coefficients), there was evidence of an important positive association between participation in the Rome Program and persistence. Based on the b weight in the regression equation, holding all other variables constant, students who participated in the Rome Program persisted on average .83 ...

Creator: Warren, Ann Marie
Description: Intimate partner violence is endemic in the United States. According to the American Medical Association (1992), one-fifth to one-third of women will sustain violence from a partner or ex-partner in their lifetime. The relevant literature was organized by ICD-9-CM categories. This study examined the health consequences of partner abuse in a sample of community women using a sample consisting of 564 women in three ethnic groups. Because prior research has failed to account for variations by type of abuse on health consequences, this study assessed psychological abuse, violence and sexual aggression by women's partners. To determine whether or not different types of abuse had an effect on women's health, hierarchical regression analyses were conducted. The regression equations were calculated for women within each ethnic group to facilitate identification of similarities and differences and to control for ethnic differences in risk for specific diseases. The results were consistent with past research on health consequences of abuse and extended the prior literature by showing that psychological abuse had a pervasive effect on health conditions, distress and use of health care resources. Additionally, ethnic differences emerged. As expected, ethnicity appeared to function as a moderator. Clinical implications and recommendations are made for future ...

Perceiving matter in  notes on space, undated (log 3)  by André du Bouchet, Fontfroide-le-Haut, Fata Morgana, 2000

Perceiving matter in notes on space, undated (log 3) by André du Bouchet, Fontfroide-le-Haut, Fata Morgana, 2000

Date: December 2003
Creator: Simmons, Sandra
Description: This study of the graphic field in notes on space, undated (log 3) focuses on how the white emptiness of a page plays a structural role in the articulation of dissociated fragments of notes. According to the criteria of three theorists (Genette, Lapacherie, Baetens), the distinction between non-linear and tabular proves to be non-exclusive in this particular work. Ostensibly, this non-figurative writing instigates interactive contemplation and lends itself to multiple entries, like an object one contemplates from every possible visual perspective without ever constructing a representation or image. The poetic form that du Bouchet explores renders perceptible the latent materiality of all text.

Perceptions of Parents of Postsecondary Education Students Concerning Parental Notification and Underage Alcohol Offenses

Perceptions of Parents of Postsecondary Education Students Concerning Parental Notification and Underage Alcohol Offenses

Date: December 2003
Creator: Clouse, Maureen McGuinness
Description: Since the inception of the Higher Education Reauthorization Act of 1998 by the United States Congress, there has been limited research conducted on parental notification policies on campuses of Higher Education concerning alcohol and drug offenses committed by students. This study surveyed parents of incoming freshmen at the University of North Texas regarding their perceptions of Parental Notification policies and their perceptions of underage alcohol offenses by gender, age, ethnicity, and parental status. The relationship between parental notification and underage alcohol offenses was also examined. This study, conducted in the summer of 2002, at the University of North Texas had 539 respondents. An instrument developed to determine parental perceptions of underage alcohol use and parental notification consisted of 20 dichotomous questions. Chi-square tests of independence were used to analyze the data because it could calculate the relationships between two sets of nominal data. Data show that most parents want to be notified in all situations involving underage alcohol offenses and their offspring. Generally, parents do not believe their offspring will use alcohol underage as they enter college and that they are not binge drinkers. Females want to be notified about their student's underage alcohol offenses at a higher rate than ...

Performance Evaluation of Data Integrity Mechanisms for Mobile Agents

Performance Evaluation of Data Integrity Mechanisms for Mobile Agents

Access: Use of this item is restricted to the UNT Community.
Date: December 2003
Creator: Gunupudi, Vandana
Description: With the growing popularity of e-commerce applications that use software agents, the protection of mobile agent data has become imperative. To that end, the performance of four methods that protect the data integrity of mobile agents is evaluated. The methods investigated include existing approaches known as the Partial Result Authentication Codes, Hash Chaining, and Set Authentication Code methods, and a technique of our own design, called the Modified Set Authentication Code method, which addresses the limitations of the Set Authentication Code method. The experiments were run using the DADS agent system (developed at the Network Research Laboratory at UNT), for which a Data Integrity Module was designed. The experimental results show that our Modified Set Authentication Code technique performed comparably to the Set Authentication Code method.

Creator: Lee, Kenneth Oneal
Description: There are two major, well-known operas based on plays of Tennessee Williams. He refused many times throughout his life to give permission for his play, A Streetcar Named Desire, to be set as an opera. It was not until the 1960s that he granted permission for Lee Hoiby to choose any of his plays as a basis for a new opera. Hoiby chose Summer and Smoke, a play which was written at approximately the same time as Streetcar. Lanford Wilson created the libretto for the opera which was given its premier in 1971 by the St. Paul Opera Association. In 1994 representatives of the Williams estate granted permission to the San Francisco Opera to commission an opera based on A Streetcar Named Desire. With a libretto by Philip Littell, the opera was composed by André Previn and given its premier in 1998. These two plays share common themes, character types, character relationships, and literary symbols due in part to the autobiographical nature of Williams's writings. The plays exhibit a cinematic nature and possess common dramatic elements such as the symbolic use of sets, props, and musical leitmotifs as a result of his attempts to create a new "plastic" style of ...

Creator: Henry, Benny
Description: Not many artists have made a successful connection between art and text. In this installation of four works of art, I have given a new perspective on commerce by combining my poetry with common products. The content of my work is based on experiences I have had throughout my life. I believe that I have successfully combined my poems and art into cohesive works that break through the conventional understanding of products and their packaging.

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 ...
