Participant's perceptions of online staff development and learning tools.

Participant's perceptions of online staff development and learning tools.

Date: May 2003
Creator: Smolka, Jennifer
Description: This study analyzed participants in an online professional development and certification program can to see if they could predict the learning value of individual distance education tools. The Texas Center for Educational Technology (TCET) funded by the Texas Telecommunications Infrastructure Fund (TIF) designed the Technology Applications Certification Program (TACP). In the TACP, students are offered four graduate level classes which, when combined, meet the standards for the State Board for Educator Certification (SBEC) Technology Applications certification. The four courses that comprise the TACP are Computers in Education, Introduction to the Internet, Multimedia in Technology Applications, and Introduction to Video Technologies. The first course started in January 2002 with approximately 706 participants in 40 cohorts across the state of Texas. The TACP combines two different worlds of technology training. Half of the coursework was completed through asynchronous content and discussions, while the remaining classes were hands-on classes in local district computer labs. These face-to-face meetings enabled learners to get hands-on training with direct assistance. Between the online and face-to-face segments, a variety of learning tools were introduced to the participants. Participants were surveyed through the online Snapshot Survey in January and again in September.

Perceived value of journals for academic prestige, general reading and classroom use: A study of journals in educational and instructional technology.

Perceived value of journals for academic prestige, general reading and classroom use: A study of journals in educational and instructional technology.

Date: May 2003
Creator: Bray, Kaye Evitt
Description: Conducting research, evaluating research, and publishing scholarly works all play an extremely prominent role for university faculty members. Tenure and promotion decisions are greatly influenced by the perceived value of publications as viewed by members of faculty evaluation committees. Faculty members seeking tenure may be limited to publishing in a limited group of journals perceived to be valuable by members of an academic committee. This study attempted to determine the value of various kinds of periodicals (journals, magazines, and e-journals), based on three principal criteria, as perceived by professionals (university faculty, K-12 practitioners, and corporate trainers) in the educational/instructional technology (E/IT) field. The criteria for journal evaluation were Academic Prestige, General Reading, and Classroom Use. The perceived value of journals based on each criterion was compared to determine any significant differences. Members of the Association for Educational Communications and Technology (AECT) were asked to rate 30 journals in the E/IT field using the three criteria. Statistically significant differences were found among ratings in 63% of the journals. The statistical analyses indicated that differences in the perceived value of journals among E/IT professionals across the three criteria (Academic Prestige, General Reading, and Classroom Use) were statistically significant. It is also noted ...

Personality Correlates of Eating Disorder Symptomatology in a Nonclinical Sample of Female Undergraduates

Personality Correlates of Eating Disorder Symptomatology in a Nonclinical Sample of Female Undergraduates

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Baker, Kristine Genovese
Description: Research indicates the existence of an eating disorder continuum. The two-component model of disordered eating suggests that certain personality traits may increase an individual's vulnerability to develop more severe variants of disordered eating symptomatology. The present study investigates pre-clinical elevations on a measure of personality based on the Five-Factor Model (FFM) and pre-clinical elevations on a measure of eating disorder symptomatology in a sample of nonclinical undergraduates. The personality dimensions Neuroticism, Extraversion, and Agreeableness accounted for 7% of the variability in Body Dissatisfaction. Subcomponents comprising the personality dimensions of the FFM as determined by Saucier (1998) (see Appendix A) were analyzed. The Self-Reproach and Intellectual Interests subcomponents were the strongest predictors of Drive for Thinness and Body Dissatisfaction. The subcomponent Sociability was the strongest predictor of Bulimia. Findings present implications for prevention and treatment interventions. Longitudinal studies are needed to determine the temporal directionality of personality and disturbed eating.

Play Therapy Instruction: A Model Based On Objectives Developed by the Delphi Technique

Date: May 2003
Creator: Joiner, Kimberly D.
Description: The purpose of this study was to determine the core skills/methods and practicum experiences play therapy experts and professors believe to be essential in the education of the beginning play therapist in the specific areas of theory and history, terms, organizations, authors who have contributed to the field, methods, skills, training in special populations, practicum experience, and advanced skills. Two questionnaires were used to obtain opinions from play therapy experts and play therapy instructors. The first questionnaire was sent to twelve play therapy experts to obtain their opinions on the core curriculum and experiences necessary for training a play therapist in an introductory play therapy class, practicum experience, and advanced play therapy training. Frequencies and means were obtained and used to delete and add items for Questionnaire II. Questionnaire II was sent to 180 play therapy professors. Fifty play therapy professors returned the instrument. The ratings on Questionnaire II given by the professors were used to provide curriculum guidelines for developing a play therapy program. This program includes an introduction to play therapy course, play therapy practicum experiences, and advanced skills and advanced practicum experiences.

The Political Economy of Organizational Expansion. Finding the Link Between Insider and Outsider in the European Union

The Political Economy of Organizational Expansion. Finding the Link Between Insider and Outsider in the European Union

Date: May 2003
Creator: Schneider, Christina J.
Description: Scholars often address the process of enlargement as one-sided argument. This work provides a general theory of organizational expansion by including strategies and actions of both, applicant states and members of international organizations. It is argued that dependent on the domestic characteristics of states an organization strategically implement a set of conditions to avoid the application and admission of states, which are either not able to conform with the rules or not willing to pay the costs of membership. This process incorporates two stages. I test this theory by utilizing a Heckman-Probit-Selection Model, which accounts for this two-stage procedure. The results confirm that conditions are important to avoid costs in the process of expansion.

Pop Baroque

Pop Baroque

Date: May 2003
Creator: Gassiraro, Jennifer
Description: My objective was to make a body of work that used baroque sensibilities with my own connections to popular culture. A series of mixed media works and one installation were created that infused baroque motifs with present popular design. My interpretation of the presence of the Baroque was expanded by using vivid colors, textures, patterns and designs collected from my environment during an investigation of the theatrical fantasies of popular culture. I expected to make work that could be approached conceptually from different angles, while being seductive on the surface.

Precision measurements of the hyperfine structure in the 23P state of 3He.

Date: May 2003
Creator: Smiciklas, Marc
Description: The unusually large hyperfine structure splittings in the 23P state of the 3He isotope is measured using electro-optic techniques with high precision laser spectroscopy. Originally designed to probe the fine structure of the 4He atom, this experimental setup along with special modifications I implemented to resolve certain 3He related issues has made possible new high precision hyperfine structure measurements. Discussed are the details of the experimental setup and the modifications, including in depth information necessary to consider while performing these measurements. The results of these hyperfine structure measurements give an order of magnitude improvement in precision over the best previously reported values.

Predicting institutional behavior in youthful offenders: The role of individual and family factors in risk assessment.

Predicting institutional behavior in youthful offenders: The role of individual and family factors in risk assessment.

Date: May 2003
Creator: Martin, Mary A.
Description: A vigorous debate persists in the literature about the efficacy of clinical judgment and actuarial models of risk assessment. This study was designed to augment those commonly used methods by integrating a variety of factors that produce risk and protective effects among 101 youthful offenders. Adolescents and young adults in a maximum-security facility were interviewed with the Psychopathy Checklist: Youth Version (PCL:YV), and completed self-reports of psychopathy, impulsivity, and perceived parental care and protection. This selection of empirically-supported predictors was enhanced by criminal history and family information obtained through extensive file review. Markedly different prediction models emerged based on age. ADHD and PCL Factor 2 predicted adolescents' institutional maladjustment. In contrast, young adults' institutional behavior was influenced by impulsivity, family substance abuse, and gang membership. Treatment progress also differed depending on age; the absence of certain risk factors predicted success for adolescents, while academic achievement and intelligence facilitated young adults' advancement. Importantly, support was demonstrated for the moderating effects of protective factors on violence. Finally, the predictive validity of newly-developed psychopathy self-reports was examined in relation to the PCL:YV. Both the SALE PS-24 and the APSD were modestly effective at differentiating between high and low levels of psychopathy.

The predictive influence of variables in three different academic learning environments on the intentions of music education majors to leave the degree program.

The predictive influence of variables in three different academic learning environments on the intentions of music education majors to leave the degree program.

Date: May 2003
Creator: Corley, Alton L.
Description: Attrition rates among students in music teacher training programs have contributed to a shortage of qualified music teachers for the nation's schools. The purpose of this study was to investigate the predictive relationship of academic variables in three different learning environments and the intent of a select population of music education majors to leave the degree program. The study drew upon the work of Tinto, Bean and Astin to form a theoretical foundation for examining variables unique to student withdrawal from the music education degree plan. Variables were examined within the context of three different learning environments: (1) applied lessons, (2) ensembles and (3) non-performance courses. Participants were 95 freshmen and sophomore music education majors at a public university who were enrolled in the music education degree program during the spring semester, 2002. Data included participant responses on the Music Student Inventory (MSI), a questionnaire developed specifically for the study, and grade data from university records. Independent variables in the study included participants' perceptions of (1) Ensemble experiences, (2) Applied lesson experiences, (3) Non-performance music course experiences, (3) Course requirements, and (4) Performance growth. Additional variables included: (1) Ensemble placement, (2) Course grades for music theory, applied lessons and aural ...

Process environmental philosophy

Process environmental philosophy

Date: May 2003
Creator: Corbeil, Marc J.V.
Description: A process-information approach is examined as a foundation for an environmental philosophy that is dynamic and elastic, with particular emphasis on value, beauty, integrity and stability supporting Aldo Leopold's vision. I challenge one of the basic assumptions of Western philosophy, namely the metaphysical primacy of substance. The classical, medieval and modern metaphysics of substance is presented with particular attention given the paradoxes of substance. Starting from the philosophy of Heraclitus, relatively ignored by the Western tradition of philosophy, a process philosophy is developed as an alternative to standard metaphysical attitudes in philosophy. A possible resolution of Zeno's paradoxes leads to consideration of other paradoxes of substance metaphysics. It is argued that substance metaphysics is incompatible with evidence found in the shifting paradigms of ecology and general science. Process philosophy is explored as a basis for an environmental philosophy, attempting to put the environment back into philosophy.

The Production Effects of Protectionist Announcements: An Examination of the Steel Industry

The Production Effects of Protectionist Announcements: An Examination of the Steel Industry

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Pharr, Matthew C.
Description: The well-being of the American steel industry is vital to the overall health of the United States (U.S.) economy. This belief is, in part, the impetus for the enactment of protective tariffs and quotas. This paper examines the impact of the announcement of the 2001 tariffs. Numerous forces have buffeted the U.S. steel industry over the last decade. Domestic steel firms operate in a highly global, fiercely competitive, and capital-intensive industry. This environment has proven inhospitable to the U.S. steel industry, widely criticized for inefficiency and overcapacity. A regression analysis finds that the announcement of the 2001 tariffs had no statistically significant impact on U.S. domestic raw steel production. Supporting theories are reexamined, and the implications of this finding for trade policy are explored.

Quantization Of Spin Direction For Solitary Waves in a Uniform Magnetic Field

Quantization Of Spin Direction For Solitary Waves in a Uniform Magnetic Field

Date: May 2003
Creator: Hoq, Qazi Enamul
Description: It is known that there are nonlinear wave equations with localized solitary wave solutions. Some of these solitary waves are stable (with respect to a small perturbation of initial data)and have nonzero spin (nonzero intrinsic angular momentum in the centre of momentum frame). In this paper we consider vector-valued solitary wave solutions to a nonlinear Klein-Gordon equation and investigate the behavior of these spinning solitary waves under the influence of an externally imposed uniform magnetic field. We find that the only stationary spinning solitary wave solutions have spin parallel or antiparallel to the magnetic field direction.

Resource Efficient and Scalable Routing using Intelligent Mobile Agents

Resource Efficient and Scalable Routing using Intelligent Mobile Agents

Date: May 2003
Creator: Amin, Kaizar Abdul Husain
Description: Many of the contemporary routing algorithms use simple mechanisms such as flooding or broadcasting to disseminate the routing information available to them. Such routing algorithms cause significant network resource overhead due to the large number of messages generated at each host/router throughout the route update process. Many of these messages are wasteful since they do not contribute to the route discovery process. Reducing the resource overhead may allow for several algorithms to be deployed in a wide range of networks (wireless and ad-hoc) which require a simple routing protocol due to limited availability of resources (memory and bandwidth). Motivated by the need to reduce the resource overhead associated with routing algorithms a new implementation of distance vector routing algorithm using an agent-based paradigm known as Agent-based Distance Vector Routing (ADVR) has been proposed. In ADVR, the ability of route discovery and message passing shifts from the nodes to individual agents that traverse the network, co-ordinate with each other and successively update the routing tables of the nodes they visit.

Robert Schumann's Symphony in D Minor, Op. 120: A Critical Study of Interpretation in the Nineteenth-Century German Symphony

Robert Schumann's Symphony in D Minor, Op. 120: A Critical Study of Interpretation in the Nineteenth-Century German Symphony

Date: May 2003
Creator: Hellner, Jean Marie
Description: Robert Schumann's D-minor Symphony endured harsh criticism during the second half of the nineteenth century because of misunderstandings regarding his compositional approach to the genre of the symphony; changes in performance practices amplified the problems, leading to charges that Schumann was an inept orchestrator. Editions published by Clara Schumann and Alfred Dörffel as well as performing editions prepared by Woldemar Bargiel and Gustav Mahler reflect ideals of the late nineteenth century that differ markedly from those Schumann advanced in his 1851 autograph and in the Symphony's first publication in 1853. An examination of the manuscript sources and the editions authorized by Schumann reveals that he imbued the Symphony with what he called a "special meaning" in the form of an implied narrative. Although Schumann provided no written account of this narrative, it is revealed in orchestrational devices, particularly orchestration, dynamics, and articulation, many of which have been either altered or suppressed by later editors. A reconsideration of these devices as they are transmitted through the authorized sources permits a rediscovery of the work's special meaning and rectifies long-standing misperceptions that have become entrenched in the general literature concerning Schumann in general and the D-minor Symphony in particular.

Creator: Akhmadullin, Iskander
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.

Security problems in 802.11 wireless networks standard due to the inefficiency of wired equivalent privacy protocol.

Date: May 2003
Creator: Samanthapudi, Varma
Description: Due to the rapid growth of wireless networking, the fallible security issues of the 802.11 standard have come under close scrutiny. Nowadays most of the organizations are eager to setup wireless local area networks to reduce the hassles of limited mobility provided by conventional wired network. There are serious security issues that need to be sorted out before everyone is willing to transmit valuable corporate information on a wireless network. This report documents the inherent flaws in wired equivalent privacy protocol used by the 802.11 standard and the ensuing security breaches that can occur to a wireless network due to these flaws. The solutions suggested in this report might not actually make the 802.11 standard secure, but will surely help in the lead up to a secure wireless network standard.

Sex and Gender Differences in Perceived and Actual Leadership Performance: Self- and Subordinate Views

Sex and Gender Differences in Perceived and Actual Leadership Performance: Self- and Subordinate Views

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Rivero, Arlene Jean
Description: The purpose of this study was to examine how male and female leaders view their own effectiveness as compared to their objective performance. This study also examined sex and gender differences in subordinate's views of male and female leaders. Forty-two mixed-sex groups led by appointed male and female leaders were observed to assess objective and perceived leader effectiveness. Gender role of participants was assessed using the Bem Sex Role Inventory (BSRI). No sex or gender differences were found in objective leadership effectiveness. An unexpected finding was that male and female leaders perceived themselves accurately as leaders. Significant differences were found in the way male subordinates rated men and women leaders when taking into account gender role. Results indicated that the study of gender bias in leadership is complex and should be examined in conjunction with gender role. Social role theory helps to explain this bias.

Short-Term Child-Centered Play Therapy Training With School Counselors and Teachers in Israel

Date: May 2003
Creator: Kagan, Suzi
Description: This study was designed to determine the effectiveness of short-term child-centered play therapy training with school counselor and teachers in Israel. A short-term child-centered play therapy course is an intervention that focuses on changing trainees attitudes and beliefs towards children while teaching them child-centered play therapy theory and skills. The experimental group, consisting of 18 volunteer school counselors and teachers in Israel received a total of 15 hours of child-centered play therapy didactic training with a variety of learning experiences. The control group consisted of 15 volunteer school counselors and teachers in Israel. The control group did not receive any training. All participants completed the Play Therapy Attitude-Knowledge-Skill Survey (PTAKSS) before and after the training as a means of measuring change in attitude, knowledge and skill. A second purpose of this study was to compare the effectiveness of short-term child-centered play therapy training with a comparison group semester long child-centered play therapy training course at the University of North Texas. An analysis of covariance revealed statistically significant positive increase in Knowledge subscale as compared to the control group. However the differences between the experimental and the control group were not significant on the participant's total score on the PTAKSS, their ...

Side By Side: Reinventing Mother/Daughter Relationships

Date: May 2003
Creator: Holzgraefe, Sandi
Description: Beginning with mother/daughter film classics such as Stella Dallas (1937) and Mildred Pierce (1945), and moving to consider recent mother/daughter texts, Anywhere But Here (1999) and "Gilmore Girls" (2000 -), this thesis, in both its written and visual components, examines the multiple and often contradictory ways in which mothers and daughters have been represented in popular culture. Challenging the discourses that singularly stress struggle and separation, this research highlights representations that emphasize mother/daughter connection, and examines how such identification empowers mothers and daughters. This project is guided by cultural studies and feminist film theories. The first two chapters outline past and present paradigms of mothers and daughters respectively; the third chapter examines the goals and findings of the visual component.

Structure property and deformation analysis of polypropylene montmorillonite nanocomposites.

Structure property and deformation analysis of polypropylene montmorillonite nanocomposites.

Date: May 2003
Creator: Hernandez-Luna, Alejandro
Description: Nanocomposites with expandable smectites such as montmorillonite layered silicates (MLS) in polymer matrices have attracted extensive application interest. Numerous MLS concentrations have been used with no particular justification. Here, we investigate the effects of MLS dispersion within the matrix and on mechanical performance. The latter is resolved through a three-prong investigation on rate dependent tensile results, time dependent creep results and the influence of a sharp notch in polypropylene (PP) nanocomposites. A fixed concentration of maleated polypropylene (mPP) was utilized as a compatibilizer between the MLS and non-polar PP. Analysis of transmission electron micrographs and X-ray diffraction patterns on the surface and below the surface of our samples revealed a unique skin-core effect induced by the presence of clay. Differential scanning calorimetric and polarized optical microscopic examination of spherulites sizes showed changes in nucleation and growth resulting from both the maleated PP compatibilizer and the MLS. These structural changes resulted in a tough nanocomposite, a concept not reported before in the PP literature. Nonlinear creep analysis of the materials showed two concentrations 3 and 5 % wt of PP, which reduced the compliance in the base PP. The use of thermal wave imaging allowed the identification of ductile failure among ...

Student preferences in screen design factors for Internet delivered college courses.

Student preferences in screen design factors for Internet delivered college courses.

Date: May 2003
Creator: Pineau, Joseph Roy
Description: Colleges and universities throughout the world are offering many of their courses via the Internet. Some institutions offer entire degrees online. This has ushered in a renewed interest in the debate on the effectiveness of non-traditional course delivery method. Numerous educational research studies have been conducted in an attempt to quantify that effectiveness. In any form of experimental research, control of variables is paramount. The rich multimedia capabilities of the World Wide Web give educators a wide variety of delivery media. However, with the exception of advice from artisans on design factors of the media, little research has been conducted with regard to the aesthetics of Web page design as viewed by the student. This study was conducted in an effort to establish student preferences with regard to two factors of Web page design as they might be used on those Web pages, background color and typeface used for text. In addition, it contains an analysis of whether or not there is an interaction between the two factors. Use of the results of this study should prove beneficial to both educators and educational researchers in their future endeavors.

Students' Perception of Videoconference Courses: A Case Study of the University of North Texas

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Christopher, Chris-Junior
Description: The objective of the survey is to observe students' perceptions of videoconference courses offered by the University of North Texas (UNT). The perceptions of 348 students enrolled in videoconferencing (VC) courses in the fall 2002 semester were obtained through a 29-item course evaluation questionnaire. From this study, I conclude generally that UNT students perceive videoconference courses as a positive stride in providing classes. While it was expected that students at remote sites would experience greater technological problems and lower levels of student/teacher interaction, evaluations from remote sites indicate higher degrees of student satisfaction than those students taking VC courses at the main campus location.
