Creator: Necsoiu, Dorel Marius
Description: Throughout history floods have been part of the human experience. They are recurring phenomena that form a necessary and enduring feature of all river basin and lowland coastal systems. In an average year, they benefit millions of people who depend on them. In the more developed countries, major floods can be the largest cause of economic losses from natural disasters, and are also a major cause of disaster-related deaths in the less developed countries. Flood disaster mitigation research was conducted to determine how remotely sensed data can effectively be used to produce accurate flood plain maps (FPMs), and to identify/quantify the sources of error associated with such data. Differences were analyzed between flood maps produced by an automated remote sensing analysis tailored to the available satellite remote sensing datasets (rFPM), the 100-year flooded areas "predicted" by the Flood Insurance Rate Maps, and FPMs based on DEM and hydrological data (aFPM). Landuse/landcover was also examined to determine its influence on rFPM errors. These errors were identified and the results were integrated in a GIS to minimize landuse / landcover effects. Two substantial flood events were analyzed. These events were selected because of their similar characteristics (i.e., the existence of FIRM or ...

The developmental stages of concern of teachers toward the implementation of the Information Technology curriculum in Kuwait

The developmental stages of concern of teachers toward the implementation of the Information Technology curriculum in Kuwait

Date: August 2000
Creator: Alshammari, Bandar S.
Description: Change is best carried out by individual teachers, and, thus, identifying and resolving teachers’ concerns about an innovation is imperative in guiding the change process to a successful point of implementation. The purpose of this study was to identify concerns that teachers experienced when implementing the Information Technology curriculum in all intermediate schools in Kuwait and to examine the relationships among teachers’ reported stages of concern and other factors, such as gender and experience. The stages of concern, one dimension of the Concerns-Based Adoption Model (CBAM), was applied to reveal teachers’ concerns. The Stages of Concern Questionnaire (SoCQ) and a demographic survey were completed by 248 respondents. The SoCQ measures seven stages of concern that reflect three dimensions: self (awareness, informational, and personal); task (management); and impact (consequence, collaboration, and refocusing Group profile analysis revealed that teachers had four high concerns related to collaboration, personal, refocusing, and informational stages. Teachers also reported low concerns at the management and awareness stages. Both females and males reported collaboration as their greater concern. Teachers with more years of experience reported higher impact concerns. The analysis of individuals’ peak concerns revealed that the majority of the respondents were adopters of the innovation. The analysis ...

Diffusion barriers/adhesion promoters. Surface and interfacial studies of copper and copper-aluminum alloys

Diffusion barriers/adhesion promoters. Surface and interfacial studies of copper and copper-aluminum alloys

Date: August 2000
Creator: Shepherd, Krupanand Solomon
Description: The focus of this research is to study the interaction between copper and the diffusion barrier/adhesion promoter. The behavior of copper sputter-deposited onto sputter-cleaned tantalum nitride is investigated. The data show that copper growth on tantalum nitride proceeds with the formation of 3-D islands, indicating poor adhesion characteristics between copper and Ta0.4N. Post-annealing experiments indicate that copper will diffuse into Ta0.4N at 800 K. Although the data suggests that Ta0.4N is effective in preventing copper diffusion, copper's inability to wet Ta0.4N will render this barrier ineffective. The interaction of copper with oxidized tantalum silicon nitride (O/TaSiN) is characterized. The data indicate that initial copper depositions result in the formation a conformal ionic layer followed by Cu(0) formation in subsequent depositions. Post-deposition annealing experiments performed indicate that although diffusion does not occur for temperatures less than 800 K, copper "de-wetting" occurs for temperatures above 500 K. These results indicate that in conditions where the substrate has been oxidized facile de-wetting of copper may occur. The behavior of a sputter-deposited Cu0.6Al0.4 film with SiO2 (Cu0.6Al0.4/SiO2) is investigated. The data indicate that aluminum segregates to the SiO2 interface and becomes oxidized. For copper coverages less than ~ 0.31 ML (based on a Cu/O ...

"Documenting" East Texas: Spirit of Place in the Photography of Keith Carter

"Documenting" East Texas: Spirit of Place in the Photography of Keith Carter

Date: August 2000
Creator: Lutz, Cullen Clark
Description: This thesis examines similarities in photographs made by the contemporary photographer Keith Carter and photographers active with the Farm Security Administration during the 1930s. Stylistically and in function, works by Carter and these photographers comment on social and cultural values of a region. This thesis demonstrates that many of Carter's black and white photographs continue, contribute to, and expand traditions in American documentary photography established in the 1930s. These traditions include the representation of a specific geographic place that evokes the spirit of a time and place, and the ability to communicate to a viewer certain social conditions and values related to such a place.

Earth Ascending: A composition in three movements for female voice, electroacoustic music, and video

Earth Ascending: A composition in three movements for female voice, electroacoustic music, and video

Date: August 2000
Creator: Lillios, Elainie
Description: Earth Ascending is a composition in three movements scored for female voice, electroacoustic music, and video. Composed in the Year 2000, Earth Ascending lasts approximately sixteen minutes and was created specifically for live performance in which all three elements combine to create a sonic and visual environment. As such, no single element has greater importance than any other, with each of the three performing forces assuming a foreground role at various times throughout the work. Earth Ascending is defined by a single poem written by contemporary female British poets Jeni Counzyn, Jehanne Mehta, and Cynthia Fuller. The movements are named according to the title of each poem: Earth-Body, Light-Body; Wringcliff Beach; and Pool. The movements are separated in performance by five seconds of silence and black on the video screen. The paper accompanying the score of Earth Ascending is divided into five chapters, each discussing in detail an element central to the composition itself. The Introduction presents background information, general ideas, and approaches undertaken when creating the work. Chapters 1 through 3 investigate in detail the content of the electroacoustic music, voice, and video. Chapter 4 discusses scoring techniques, revealing approaches and methods undertaken to solve issues relating to notation ...

The Effectiveness of an Infant Simulator as a Deterrent to Teen Pregnancy Among Middle School Students

The Effectiveness of an Infant Simulator as a Deterrent to Teen Pregnancy Among Middle School Students

Date: August 2000
Creator: Hillman, Carol Best
Description: This research was one of the first longitudinal studies to determine the effectiveness of a computerized infant simulator as a deterrent to adolescent pregnancy. All of the female eighth-grade students (221) in 1994-1995 and 1995-1996 from a suburban North Texas middle school were part of this study. They were tracked from the eighth grade through high school graduation to determine whether and when pregnancies occurred. The Kaplan-Meier procedure for survival analysis was used to determine test statistics. Survival functions and hazard functions were created for each independent variable--parenting the infant simulator, ethnic and racial, involvement in co-curricular activities, and crime. Results showed the computerized infant simulator to be highly effective in postponing the on-set of pregnancies for those students who participated in the parenting simulation. Hazards peaked at 3 years, 2 months for the experimental group and at 2 years, 21/2 months for the control group. Summertime and holiday seasons marked times of the year when the majority of pregnancies occurred. Caucasians peaked before the Other ethnic group. No significant differences were detected in regard to involvement in co-curricular activities, and no involvement in crime was self-reported. The model was developed to use as a guideline for implementing a pregnancy ...

The effects of a feedback package on the facial orientation of a young girl with autism during restricted and free operant conditions

The effects of a feedback package on the facial orientation of a young girl with autism during restricted and free operant conditions

Date: August 2000
Creator: Jacobs, Wendy Lynn
Description: A multiple baseline design across activities and people was used to assess the effectiveness of a feedback package on the facial orientation of a young girl with autism. During baseline, observations indicated low rates of facial orientation and high rates of gaze avoidance during conversation (restricted operant) and play (free operant) conditions. After treatment, facial orientation rates increased and gaze avoidance rates decreased to levels similar to typically-developing peers and maintained at one month follow up. These results suggest that the feedback package was effective in producing durable facial orientation across different environments and people. Possible interpretations, strengths, and limitations are discussed.

Effects of goal setting, e-mail feedback and graphic feedback on the productivity of public school attendance clerks

Effects of goal setting, e-mail feedback and graphic feedback on the productivity of public school attendance clerks

Date: August 2000
Creator: Rexroat, Robin D.
Description: A package intervention, consisting of daily-adjusted goal setting, e-mail feedback, and graphic feedback, was used in a public school attendance office to increase the efficiency with which 3 attendance clerks documented student attendance. During the intervention phase, the attendance secretary set a daily goal for each attendance clerk. This goal was a percentage of student absences to be coded and entered in the school computer program. After establishing a daily goal, the attendance secretary provided daily feedback, in the form of a written e-mail response and graphed feedback to each clerk. If the subjects had attained their daily goal, the attendance secretary also delivered a praise statement along with the e-mail feedback. Results indicated that the intervention package was ineffective in producing change in the attendance clerks' absence coding behavior.

Date: August 2000
Creator: Jones, Elizabeth Murphy
Description: This study was design to determine the efficacy of intensive individual play therapy as a method of intervention for children diagnosed with insulin-dependent diabetes mellitus. The purpose of this study was designed to study the effectiveness of an intensive play therapy intervention in: a) reducing symptoms of childhood depression in children with IDDM; b) reducing symptoms of anxiety in children with IDDM; c) reducing the overall behavior difficulties in children with IDDM; d) increasing healthy adjustment in children with IDDM; e) increasing diabetic's children's adherence to their diabetic regime; and f) impacting these emotional and behavioral symptoms over time. The 15 children in the experimental group received 12, daily play therapy sessions while attending a summer camp for children with diabetes. The control group, consisting of 15 children who attended the diabetic summer camp, received no play therapy. Children and parents in both groups completed pretest, post-test and three-month follow-up data, consisting of: the Children's Depression Inventory, the Revised Children's Manifest Anxiety Scale, the Filial Problems Checklist and the Diabetes Adaptation Scale. Analysis of covariance revealed that the children in the experimental group significantly improved their adaptation to their diabetes following intensive play therapy as reflected by the Diabetes Adaptation ...
