What Would a Waterbird Do? An Annual Study of 13 Urban Wetlands in Frisco, Texas
Intention for this study is driven by finding patterns that may be shown to reveal primary factors of influence for the abundance and diversity of wetland birds. These correlations may be used to promote wetland management strategies for the benefit of waterbird species, and help illuminate current local wetland conditions for waterbirds, respectively. The idea is to help enliven individuals to become a more conscious steward and manipulator of our environment through incorporating structural and biological components into wetland development and management strategies, and broadly speaking, urban development practices.

Water Quality Corridor Management for Restoration (WQCM-R) Modeling Dataset
The dataset was developed to support research intended to develop a spatially-explicit model that prioritizes riparian areas in terms of potential for ecosystem restoration specifically to improve water quality downstream of the riparian area, and ultimately improve drinking water quality. The model was developed and then tested on the Lewisville Lake watershed (north central Texas, just north of Dallas, Texas, USA). The dataset contains environmental data for 90 sub-watersheds that form the overall Lewisville Lake watershed with a corresponding identification map.

Reconstruction in Collin County, Texas, 1865-1876
This is a work of local history examining the course of Reconstruction in Collin County, Texas. National and state level surveys of Reconstruction often overlook the experiences of communities in favor of simpler, broader narratives. The work proceeds chronologically, beginning with the close of the Civil War, and tells the story of Collin County as national Reconstruction progressed and relies on works of professional and non-academic historians, oral histories, census data, and newspapers to present a coherent picture of local life, work, and politics. The results exemplify the value of local history, as local conditions influenced the course of events in Collin County as much as those in Austin and Washington D.C. The story of Reconstruction in Collin County is one of anomalous political views resulting from geographical exclusion from the cotton culture of Texas followed by a steady convergence. As Reconstruction progressed, Collin County began to show solidarity with more solidly conservative Texas Counties. The arrival of railroads allowed farmers to move from subsistence agriculture to cash crop production. This further altered local attitudes toward government, labor, voting rights, and education for Freedmen. By the end of Reconstruction, Collin County had all but abandoned their contrarian social and political …

County Level Population Estimation Using Knowledge-Based Image Classification and Regression Models
This paper presents methods and results of county-level population estimation using Landsat Thematic Mapper (TM) images of Denton County and Collin County in Texas. Landsat TM images acquired in March 2000 were classified into residential and non-residential classes using maximum likelihood classification and knowledge-based classification methods. Accuracy assessment results from the classified image produced using knowledge-based classification and traditional supervised classification (maximum likelihood classification) methods suggest that knowledge-based classification is more effective than traditional supervised classification methods. Furthermore, using randomly selected samples of census block groups, ordinary least squares (OLS) and geographically weighted regression (GWR) models were created for total population estimation. The overall accuracy of the models is over 96% at the county level. The results also suggest that underestimation normally occurs in block groups with high population density, whereas overestimation occurs in block groups with low population density.

Litigation Subsequent to a Mandated Psycho-Educational Seminar for Divorcing Parents
This study was designed to assess the difference in litigation between two courts: one mandating For Kids' Sake, a psycho-educational seminar for divorcing parents, and the other not so mandating. The level of difficulty of children's adjustment to divorce has been positively correlated with parental hostility. More hostile parents would have more contested cases, interim motions, and relitigations. This research compared final dispositions, interim motions, and relitigation between parents in two courts in Collin County, Texas. The treatment group was from the 219th District Court which mandated all divorcing parents with minor children to attend the For Kids' Sake Seminar and the control group was from the 199th District Court which did not so mandate. Archival data was collected from a computer generated list for the Total group data to assess final dispositions and directly from District Clerk files for the In-Depth group data to assess interim motions and relitigation. The Total group was comprised of 679 research subjects with 330 cases in the treatment group and 349 cases in the control group. The In-Depth group consisted of 182 cases from both courts with 84 cases in the treatment group and 98 cases in the control group. Chi square analysis …

Design, Development, and Implementation of a Computer-Based Graphics Presentation for the Undergraduate Teaching of Functions and Graphing
The problems with which this study was concerned were threefold: (a) to design a computer-based graphics presentation on the topics of functions and graphing, (b) to develop the presentation, and (c) to determine the instructional effectiveness of this computer-based graphics instruction. The computerized presentation was written in Authorware for the Macintosh computer. The population of this study consisted of three intermediate algebra classes at Collin County Community College (n = 51). A standardized examination, the Descriptive Tests of Mathematics Skills for Functions and Graphs, was used for pretest and posttest purposes. Means were calculated on these scores and compared using a t-test for correlated means. The level of significance was set at .01. The results of the data analysis indicated: 1. There was a significant difference between the pretest and posttest performance after exposure to the computer-based graphics presentation. 2. There was no significant gender difference between the pretest and posttest performance after exposure to the computer-based graphics presentation. 3. There was no significant difference between the pretest and posttest performance of the traditional and nontraditional age students after exposure to the computer-based graphics presentation. Females had a lower posttest score than the mean male posttest score, but an analysis …

Nesting Ecology of the Dickcissel (Spiza americana) on a Tallgrass Prairie Relict in North Central Texas
Eighty-three species of vascular plants were inventoried on the prairie relict during peak dickcissel nesting. Based on foliar cover and occurrence frequency, the five dominant plants were heath aster (Aster ericoides), eastern gammagrass (Tripsacum dactyloides), little bluestem (Schizachyrium scoparium), sensitive briar (Schrankia roemeriana) and meadow dropseed (Sporobolus asper). Sixty-one percent of dickcissel nests were constructed on or immediately next to three plant species: eastern gammagrass, sensitive briar and green milkweed.

A Survey of Singers: Is Mental Imagery Used in the Conceptualization of Pitch and Vowel?
Mental imagery is a common theme in research that clarifies how musical thought relates to musical performance. Unfortunately, minimal information exists regarding mental imagery and singers. The purpose of this study was to probe the role, if any, mental imagery plays in the conceptualization of pitch and vowel. By interviewing singers at differing levels of expertise, basic information was obtained about the mental processes used by singers. Through evaluations of the singers' mental processes, it was concluded that 95% of the singers in the study employed mental imagery. All singers described using kinesthetic imagery, while the majority implemented sensory and auditory imagery. Viso-spatial imagery was implemented among the more experienced singers. The majority of singers also reported: imaging pitch and vowel interactively; imaging from an internal perspective; and utilizing mental rehearsal. Less than half of the singers described using methods other than mental imagery to conceptualize pitch and vowel.

A Study of the Relationship Between the Use of Color for Text in Computer Screen Design and the Age of the Computer User
This study addresses an individual's performance, relating it to eyesight changes due to the aging of the individual and to color computer screens used for computer-based-instruction not designed specifically for older students. This study determines how existing research in gerontology, human-computer interface, and color use in visual graphics can be applied to the design of computer screen displays containing color text and backgrounds and how various color combinations will affect performance by adult learners forty years of age and older. The results of this research provide software developers and instructional designers guidelines to use when designing computer screen displays for use in instructional computing settings involving older adults.

Sediment Bound Trace Metals in the White Rock Creek Watershed, Dallas and Collin Counties
Areas were sampled in the White Rock Creek Watershed to examine sediment bound trace metal distributions and sorption relationships. A Kruskal-Wallis AOV found significant among area differences for most metals, and SNK-like multiple comparisons were used to group these areas. Kruskal-Wallis AOVs similarly found among area differences for sediment components that bind trace metals (Fe and Mn oxides and organic carbon) and physicochemical conditions that influence metal sorption (particle size and pH). Multiple correlation found numerous relationships among trace metals, sediment components, and physicochemical conditions. Statistical relationships indicate that metal partitioning to various sorption factors is metal specific. White Rock Creek Watershed trace metal concentrations are comparable to those in many urban watersheds.

The Historical Development and Demise of the University of Plano
The University of Piano was a private, liberal arts college with a campus in Piano, Texas and an extended campus in Frisco, Texas. The University was incorporated in 1964 under the original name of the University of Lebanon. Classes began in temporary space in downtown Dallas in 1964 and continued on its campuses in Piano and Frisco until the summer of 1976. The University of Piano was comprised of two separate schools within the University: the School of Developmental Education and the Frisco College of Arts and Sciences. This study explores the curricula of both schools and the students and faculty who participated in both programs. This study focuses on the establishment, development and final closing of a wholly privately supported university which accepted both traditional college students and students whose basic academic skills or neurological development prevented their acceptance into traditional college programs. It addresses the history of the University, the roles of its leaders, and the lasting effects of its programs.

Imagery/Mental Practice: A Cognitive Technique for Teaching Adaptive Movement to Postoperative Spinal Patients
Postoperative spinal patients were randomly assigned to one of three treatment conditions and were taught five adaptive movements by occupational therapists. The Control group received routine hospital occupational therapy; the Placebo group participated in an imagery relaxation task unrelated to the mental practice task of the Imagery group, which was shown line drawings of the adaptive movements under study, provided movement instructions, and asked to mentally practice each movement in a familiar, daily living situation. Thirty-five patients returned for follow-up, and a measure of outcome was obtained through the use of a quantified movement assessment instrument. Subjective ratings for anxiety, rumination, and imagery were made by the occupational therapists. An occupational motoric-symbolic rating scale was developed to assess the symbolic portion of the patient's job experience. Statistical procedures including chi square, analysis of variance, and Pearson correlation were performed. Results were in the predicted direction although statistical significance was not achieved. Possible explanations for the obtained results were discussed.

A Comparative Study of the Cost of Operating the Rural High Schools of Collin County Before and After Gilmer-Aikin Legislation
Inasmuch as it has been assumed by the people of the State of Texas that the cost of operating the public school systems has risen since the Gilmer-Aikin Bills have gone into effect, the purpose of this study is to determine just what cost items have increased and to what extent. There are many cost items to be considered in the operation of a public school, and they have varied from year to year since the beginning of public school operation. This study attempts to determine those increased cost items in rural high schools which can be contributed directly to the passage of the Gilmer-Aikin Bills.
