The Effects of a Brain-based Learning Strategy, Mind Mapping, on Achievement of Adults in a Training Environment with Considerations to Learning Styles and Brain Hemisphericity

The Effects of a Brain-based Learning Strategy, Mind Mapping, on Achievement of Adults in a Training Environment with Considerations to Learning Styles and Brain Hemisphericity

Date: May 1999
Creator: Williams, Marian H. (Marian Haile)
Description: This study examined the effectiveness of Mind Mapping (a diagram of the structure of ideas in an associative manner, using graphics, color and key words) as a note-taking device in a training course in a large, high-tech corporation, as compared to traditional note-taking. The population for this study consisted of personnel employed by a major high-tech firm, that had voluntarily registered for a Mind Mapping training class. The effect of Mind Mapping was measured by the pre-test and post-test of the control and experimental groups.

The Effects of Organic Surface Amendments on Soil Nutrients and Initial Tree Establishment

The Effects of Organic Surface Amendments on Soil Nutrients and Initial Tree Establishment

Date: May 1999
Creator: Thuesen, Kevin (Kevin Andrew)
Description: This study examined the effects of replicating woodland soil surface horizonation on the nutrient status of underlying soils and the initial establishment and growth of trees. A total of 283 container grown trees were planted in a bufferzone around a future landfill site. Control amendments consisted of an 8 cm layer (0.5 m3) of wood chips applied in a circular area of 4.6 m2 around the trees' planting pit. For the treatment, a 2.5 cm layer of composted biosolids (0.15 m3 or 80 Mg/ha) was applied in a circular area of 4.6 m2 around the trees' planting pit followed by an 8 cm layer (0.5 m3) of wood chips. The results indicate that the replication of woodland soil surface attributes using composted biosolids can significantly improve the nutrient status of underlying soil. Some significant effects were seen under control conditions, too. However, the effects on tree establishment and growth parameters were, for the most part, not statistically significant.

The Effects of Task-Based Documentation Versus Online Help Menu Documentation on the Acceptance of Information Technology

The Effects of Task-Based Documentation Versus Online Help Menu Documentation on the Acceptance of Information Technology

Access: Use of this item is restricted to the UNT Community.
Date: May 1999
Creator: Bell, Thomas
Description: The objectives of this study were (1) to identify and describe task-based documentation; (2) to identify and describe any purported changes in users attitudes when IT migration was preceded by task-based documentation; (3) to suggest implications of task-based documentation on users attitude toward IT acceptance. Questionnaires were given to 150 university students. Of these, all 150 students participated in this study. The study determined the following: (1) if favorable pre-implementation attitudes toward a new e-mail system increase, as a result of training, if users expect it to be easy to learn and use; (2) if user acceptance of an e-mail program increase as expected perceived usefulness increase as delineated by task-based documentation; (3) if task-based documentation is more effective than standard help menus while learning a new application program; and (4) if training that requires active student participation increase the acceptance of a new e-mail system. The following conclusions were reached: (1) Positive pre-implementation attitudes toward a new e-mail system are not affected by training even if the users expect it to be easy to learn and use. (2) User acceptance of an e-mail program does not increase as perceived usefulness increase when aided by task-based documentation. (3) Task-based documentation ...

The Electronic Ranch: the Information Environment of Cattle Breeders

The Electronic Ranch: the Information Environment of Cattle Breeders

Date: May 1999
Creator: Hicks, Georgia Jane
Description: The present study was a longitudinal analysis of the information needs of Red Angus cattle breeders and their use of networked information services. It was based on two surveys. The first, conducted in 1995--96, polled all 1067 ranches of the Red Angus Association of America. Responses from 192 Red Angus breeders were used to determine the value of different information types and to evaluate perceptions of the greatest barriers to the adoption of network information services. The second survey, mailed to 41 Red Angus breeders in 1998, focused on early adopters and likely users of network services. Responses from 15 breeders were used to evaluate perceptions of the greatest barriers to the effective use of Web-based information services.

Ethnically mixed individuals: Cultural homelessness or multicultural integration?

Ethnically mixed individuals: Cultural homelessness or multicultural integration?

Date: May 1999
Creator: Navarrete-Vivero, Veronica
Description: Studies addressing racial/ethnic identity development have often overlooked the developmental cultural context. The impact of growing up with contradictory cultures has not been well explored. Immersion in multiple cultures may produce mixed patterns of strengths deficits. This study reviews the literature's currently inconsistent usage of the terms race, ethnicity, and culture; introduces the concept and theoretical framework of Cultural Homelessness; relates CH to multicultural integration; and develops two study-specific measures (included) to examine the construct validity of CH. The sample’s (N = 448, 67% women) racial, ethnic, and cultural mixture was coded back three generations using complex coding criteria. Empirical findings supported the CH-specific pattern of cognitive and social strengths with emotional difficulties: social adaptability and cross-cultural competence but also low self-esteem and shame regarding diff

Evolution of Vacancy Supersaturations in MeV Si Implanted Silicon

Evolution of Vacancy Supersaturations in MeV Si Implanted Silicon

Date: May 1999
Creator: Venezia, Vincent C.
Description: High-energy Si implantation into silicon creates a net defect distribution that is characterized by an excess of interstitials near the projected range and a simultaneous excess of vacancies closer to the surface. This defect distribution is due to the spatial separation between the distributions of interstitials and vacancies created by the forward momentum transferred from the implanted ion to the lattice atom. This dissertation investigates the evolution of the near-surface vacancy excess in MeV Si-implanted silicon both during implantation and post-implant annealing. Although previous investigations have identified a vacancy excess in MeV-implanted silicon, the investigations presented in this dissertation are unique in that they are designed to correlate the free-vacancy supersaturation with the vacancies in clusters. Free-vacancy (and interstitial) supersaturations were measured with Sb (B) dopant diffusion markers. Vacancies in clusters were profiled by Au labeling; a new technique based on the observation that Au atoms trap in the presence of open-volume defects. The experiments described in this dissertation are also unique in that they were designed to isolate the deep interstitial excess from interacting with the much shallower vacancy excess during post-implant thermal processing.

Faculty Identification: Effects on Culture in a Metropolitan Research University

Faculty Identification: Effects on Culture in a Metropolitan Research University

Date: May 1999
Creator: Gray, Marlene E.
Description: This utilized identification theory to determine if faculty identify with the university and recognize its mission. The study also explored how faculty differentiate between a traditional university and a metropolitan research university. Finally, the study explored whether the faculty consider the University of North Texas to be a Metropolitan Research University. UNT full-time faculty members (N=224) completed questionnaires to indicate their identification with the university and their recognition of the university mission. Analysis showed that faculty have not come to a consensus on the definition of a MRU and that they do not identify with UNT.

From Skeletons to Orchards

From Skeletons to Orchards

Date: May 1999
Creator: Thies, Paul Andrew
Description: This thesis is a creative work that is segmented into three main phases in order to display the developing poetic growth and control in the work of Paul Andrew Thies. The first phase is titled "Skeletons and Rhinoceri." It was a phase where I focused on more classical forms of poetry, namely accentual and syllabical sonnets. This phase was greatly influenced by both Charles Baudelaire and William Butler Yeats. The second phase, titled "Clandestinies," was one in which I tried to develop a more dense form. Lord Byron and Pablo Neruda were the two main influences on my work at this time, largely in terms of imaginative exoticism and figurative energy. The third section of this thesis, titled "Graffiti in the Orchard," is an exploration of my current work as a poet. In this phase, Rainer Maria Rilke was the primary influence as I began to develop a more fluid and expressive style.
