Effects of tenderness on problem solving.

Effects of tenderness on problem solving.

Date: December 2003
Creator: Kalawski, Juan Pablo
Description: The purpose of this study was to determine the effects of tenderness on problem solving. Thirty-four female undergraduates participated. In the experimental condition, participants received instructions to reproduce a specific respiratory-posturo-facial pattern that had induced tenderness in previous studies. Participants in the control condition performed a non-emotional exercise. After either the pattern or the control exercise, participants completed one of two jigsaw puzzles. One puzzle had only an empty room while the other had a family scene. For participants who worked on the room puzzle, the tenderness pattern led to longer completion times. In contrast, for participants who worked on the family puzzle, the tenderness pattern led to shorter completion times.

The value of human rights on the open market: Liberal economic policies and the achievement of personal integrity rights.

The value of human rights on the open market: Liberal economic policies and the achievement of personal integrity rights.

Date: December 2003
Creator: Harrelson-Stephens, Julie
Description: At the end of World War II, the United States emerged as a world leader, putting into place international institutions based on its own liberal economic philosophy. Since then, the world has witnessed an increasing interconnectedness among states, with economic relationships continually blurring the distinction between domestic and international, as well as between state and societal forces. Much of the world associates this increased interconnectedness with human suffering around the globe. This dissertation seeks to test the effects of economic globalization on personal integrity violations within a state, on the whole. Specifically, I examine three aspects associated with globalization, trade openness, investment and IMF funding within a state. Liberal economic theory suggests that economic relationships should foster positive gains. Particularly, economic relationships engender economic prosperity, diffusion of norms and idea, as well as the growth of a middle class which increasingly demands respect for its political and civil rights. Consistent with the liberal paradigm, I find that open trade and investment lead to improved personal integrity rights. In addition, investment which originates from the hegemon is especially likely to increase a state's respect for personal integrity rights. Conversely, IMF funding is likely to provoke protests from people in recipient countries, ...

Susceptibility of a digital turbine control system to IEEE 802.11 compliant emissions.

Susceptibility of a digital turbine control system to IEEE 802.11 compliant emissions.

Date: December 2003
Creator: Carter, Clinton E.
Description: Within the nuclear industry, there have been numerous instances of radio transmissions interfering with sensitive plant equipment. Instances documented vary from minor instrument fluctuations to major plant transients including reactor trips. With the nuclear power industry moving toward digital technologies for control and reactor protection systems, concern exists regarding their potential susceptibility to contemporary wireless telecommunications technologies. This study evaluates the susceptibility of Comanche Peak's planned turbine controls upgrade to IEEE 802.11 compliant wireless radio emissions. The study includes a review of previous research, industry emissions standards, and technical overview of the various IEEE 802.11 protocols and details the testing methodology utilized to evaluate the digital control system. The results of this study concluded that the subject digital control system was unaffected by IEEE 802.11 compliant emissions even when the transmitter was in direct contact with sensitive components.

The effects of "errorless" training and testing on the performances of typically developing children during acquisition and retention.

The effects of "errorless" training and testing on the performances of typically developing children during acquisition and retention.

Date: December 2003
Creator: Arnadottir, Iris
Description: This study examines the effects of two teaching procedures and two testing procedures (“Skip” and “Guess”) on acquisition, retention and generalization of learning. Three typically developing females between the ages of 8 and 11 learned the 24 lower case letters of the Greek alphabet. Half of the letters were taught with the “Skip” procedure and the other half with the “Guess” procedure. The “Skip” procedure produced faster and more efficient learning than the “Guess” procedure. The “Skip” procedure also resulted in better initial retention (4 weeks), but this effect disappeared in subsequent retention tests. The training conditions did not have differential effects on generalization tests across learning channels, except for the Free/Say channel.

Early Literacy: An Examination of the Principal Behaviors That Impact Reading Achievement

Early Literacy: An Examination of the Principal Behaviors That Impact Reading Achievement

Date: December 2003
Creator: Baker, Brenda
Description: Literacy is fundamental to formal education, learning, and training for future career related skills. It provides not only the means of acquisition of information and skills during schooling, but it is a vital predictor of a person's general level of education in school as well as successful completion of schooling. Literacy skills serve as the major foundational skill for all school-based learning and without it, chances for academic and occupational success are limited. Despite the efforts of teachers, a significant portion of students continue to fail to achieve success in early literacy in school, with severe consequences for their subsequent educational progress, career opportunities and life chances. The extent of this problem varies throughout school systems. All of our children are affected by their reading ability, and as educators it is critical to provide for all students the most effective literacy programs and strategies which are research based, data-driven and successfully replicated. Because of the psychological, social and economic consequences of reading failure, it is critical to review the research to determine the risk factors that may predispose youngsters to reading failure, and the instructional practices that can be applied to ameliorate reading deficits at the earliest possible time. The ...

An investigation of success metrics for the design of e-commerce Web sites.

An investigation of success metrics for the design of e-commerce Web sites.

Access: Use of this item is restricted to the UNT Community.
Date: May 2004
Creator: Cutshall, Robert C.
Description: The majority of Web site design literature mainly concentrates on the technical and functional aspects of Web site design. There is a definite lack of literature, in the IS field, that concentrates on the visual and aesthetic aspects of Web design. Preliminary research into the relationship between visual design and successful electronic commerce Web sites was conducted. The emphasis of this research was to answer the following three questions. What role do visual design elements play in the success of electronic commerce Web sites? What role do visual design principles play in the success of electronic commerce Web sites? What role do the typographic variables of visual design play in the success of electronic commerce Web sites? Forty-three undergraduate students enrolled in an introductory level MIS course used a Likert-style survey instrument to evaluate aesthetic aspects of 501 electronic commerce Web pages. The instrument employed a taxonomy of visual design that focused on three dimensions: design elements, design principles, and typography. The data collected were correlated against Internet usage success metrics data provided by Nielsen/NetRatings. Results indicate that 22 of the 135 tested relationships were statistically significant. Positive relationships existed between four different aesthetic dimensions and one single success measure. ...

Creator: Chen, Kaili
Description: Researchers have noted that by providing formal and informal social skills training (SST), the school can become a potential optimal setting that fosters the development of social competence in students with behavioral problems. Indeed, learning to get along with people is one of the most important skills that we can teach students. In order to maximize its effectiveness, SST must be motivating and personally relevant enough for students to want to use the skills. In addition, it must provide opportunities for learned skills to be practiced under varying conditions and in as close to natural situations as possible in order to enhance the transfer of training. The purpose of the study was to investigate the social competence of students aged from six to twelve, diagnosed with emotional/behavioral disorders (E/BD) in a public self-contained school setting, and to increase the students' social competence by using a literature-based method that employs multiage grouping, impersonation, and telecommunications. By providing intensive, literature-based training in a multiage classroom, the SST gave students opportunities to practice skills in a natural, real-life environment and, therefore, increased the likelihood of generalizing these skills in other settings. The employment of impersonation and telecommunications also enhanced students' acquisition of social ...

A Mythic Perspective of Commodification on the World Wide Web

A Mythic Perspective of Commodification on the World Wide Web

Date: May 2004
Creator: Robinson, Glendal Paul
Description: Capitalism's success, according to Karl Marx, is based on continued development of new markets and products. As globalization shrinks the world marketplace, corporations are forced to seek both new customers and products to sell. Commodification is the process of transforming objects, ideas and even people into merchandise. The recent growth of the World Wide Web has caught the attention of the corporate world, and they are attempting to convert a free-share-based medium into a profit-based outlet. To be successful, they must change Web users' perception about the nature of the Web itself. This study asks the question: Is there mythic evidence of commodification on the World Wide Web? It examines how the World Wide Web is presented to readers of three national publications-Wired, Newsweek, and Business Week-from 1993 to 2000. It uses Barthes' two-tiered model of myths to examine the descriptors used to modify and describe the World Wide Web. The descriptors were clustered into 11 general categories, including connectivity, social, being, scene, consumption, revolution, tool, value, biology, arena, and other. Wired articles did not demonstrate a trend in categorical change from 1993 to 2000; the category of choice shifted back and forth between Revolution, Connectivity, Scene, and Being. Newsweek ...

Impact of actual interference on capacity and call admission control in a CDMA network.

Impact of actual interference on capacity and call admission control in a CDMA network.

Date: May 2004
Creator: Parvez, Asad
Description: An overwhelming number of models in the literature use average inter-cell interference for the calculation of capacity of a Code Division Multiple Access (CDMA) network. The advantage gained in terms of simplicity by using such models comes at the cost of rendering the exact location of a user within a cell irrelevant. We calculate the actual per-user interference and analyze the effect of user-distribution within a cell on the capacity of a CDMA network. We show that even though the capacity obtained using average interference is a good approximation to the capacity calculated using actual interference for a uniform user distribution, the deviation can be tremendously large for non-uniform user distributions. Call admission control (CAC) algorithms are responsible for efficient management of a network's resources while guaranteeing the quality of service and grade of service, i.e., accepting the maximum number of calls without affecting the quality of service of calls already present in the network. We design and implement global and local CAC algorithms, and through simulations compare their network throughput and blocking probabilities for varying mobility scenarios. We show that even though our global CAC is better at resource management, the lack of substantial gain in network throughput and ...

An exploration of the relationships among teacher efficacy, collective teacher efficacy, and teacher demographic characteristics in conservative Christian schools.

An exploration of the relationships among teacher efficacy, collective teacher efficacy, and teacher demographic characteristics in conservative Christian schools.

Date: August 2006
Creator: Egger, Karen J.
Description: The purpose of this study was to determine whether teachers' perceptions of self-efficacy and collective teacher efficacy are interrelated and how these two constructs may be impacted by teacher demographic characteristics, such as educational level, grade level taught, and number of years of teaching experience. This study focused entirely on the interrelationships of teacher efficacy and collective teacher efficacy in three suburban, conservative Christian schools in north Texas. Specifically, the demographic characteristics of age, gender, ethnicity, particular school campus, number of years teaching, number of years teaching at the current school, highest degree received, type of teacher certification, certification grade level and subject area, grade level taught, and particular subject taught were studied for the non-random, convenience sample of 216 kindergarten through twelfth grade teachers. A correlational analysis of teacher efficacy and collective teacher efficacy yielded a Pearson r of .35 at a statistically significant level (p < .01); combining these two variables with teacher demographic variables in multiple regression analyses confirmed the relationship between teachers' perceptions of teacher efficacy and collective efficacy at a statistically significant level (p < .001). A review of the squared structure coefficients in the first multiple regression analysis (R2 = .284, p < .001) ...
