This study elucidates the underlying relationships for the distribution of oak landcover on bedrock and soil orders in two counties in Texas and one in Oklahoma. ESRI's ArcGis and ArcMap was used to create surface maps for Denton and Coke Counties, Texas and Choctaw County, Oklahoma. Attribute tables generated in GIS were exported into a spreadsheet software program and frequency tables were created for every formation and soil order in the tri-county research area. The results were both a visual and numeric distribution of oaks in the transition area between the eastern hardwood forests and the Great Plains. Oak distributions are changing on this transition area of the South Central Plains. The sandy Woodbine and Antlers formations traditionally associated with the largest oak distribution are carrying oak coverage of approximately 31-32% in Choctaw and Denton Counties. The calcareous Blackland and Grand Prairies are traditionally associated with treeless grasslands, but are now carrying oak and other tree landcover up to 18.9%. Human intervention, including the establishment of artificial, political and social boundaries, urbanization, farming and fire control have altered the natural distribution of oaks and other landcover of this unique georegion.

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.

The purpose of this study was to collect and compile data on the principal climatic factors of the Denton area which affect one's personal comfort and health, in order to show how a maximum of these commodities could be secured through manipulation and control of the climate of individual building sites. In the Denton County area the naturally breezy climate of summer, excluding areas near heat-collecting surfaces of pavement and masonry, is not usually uncomfortable out of doors unless one is directly exposed to the sun; but, as a result of improper orientation of houses, indoors one often feels a pressing still heat and a general discomfort. The writer's interest in the field of architecture led to a desire to find out how this condition could be alleviated; therefore, this study was undertaken.

Sorghum plants excrete phenolic acids which reduce subsequent crop yields. These acids accumulate in field soil by combining with soil and clay particles to form stable complexes which remain until degraded by bacterial metabolism. The amount of phenolic acids in soil samples were obtained by gas chromatography measurements, while Azotobacter populations were obtained by plate counts in 40 sorghum field samples from Denton County, Texas. One can conclude that increasing the Azotobacter population in the soil increased the degradation rate of phenolic acids proportionally. It is proposed that seed inoculation will introduce selected strains of Azotobacter into the soil. The presence of Azotobacter should increase crop size in subsequent plantings.

Home repairs and maintenance are a necessary responsibility of any person who maintains a home. This responsibility can usually be met in one of two ways: first, someone can be hired to do the maintenance, or the person can do it himself. However, home repairs are costly and at times prohibitive to the average person who maintains a home. Then, too, there have been times in the past, especially during the war years, when it was next to impossible to secure the services of trained mechanics for home maintenance. During such time, and out of such necessity, many people began to make their own repairs and other improvements and, as a result, a gradual "do-it-yourself" movement has invaded all sections of the country. With the changing of times, with money a little more plentiful and manpower back in civilian life, do people who maintain their homes continue to make their own home repairs?

This descriptive study of 45 multi-generational families contributes empirical knowledge about grandparent-grandchild relationships. A questionnaire was developed and completed by 74 subjects who were part of a randomly selected sample taken from a tax roll of homeowners over age 65 in Denton County, Texas. The responses provide information which expands the existing data base in the area of grandparenting. The study pinpoints areas in the grandparenting literature which need refinement and contributes data to those areas, rather than producing a set of conclusions. Areas as yet undocumented or inadequately documented in the literature are identified as the following: (a) family structural composition; (b) grandparents' personal characteristics; (c) selected aspects of grandparent-grandchild contact; and (d) satisfaction with the grandparent role. Data for these areas should help reveal factors having an impact on grandparent-grandchild relationships. A base for further investigation in these areas is established, and data are also analyzed to determine satisfaction or lack of satisfaction with grandparenting. The seventy-four subjects, from 45 households, included 44 grandmothers and 30 grandfathers. The number of generations per family was used as the base to report the findings. The study substantiates other research on grandparenting, particularly in the area of timing of grand-parenthood. Data collected in this study support the view that the grandparent's chronological age and the time in his or her life cycle when grandchildren appear (role entry), religious affiliation, lineage, and frequency of contact all contribute to satisfaction with the role of grandparent. Almost all of the respondents described themselves as satisfied grandparents and indicated their pride in and pleasure derived from their grandchildren. A strong relationship between satisfaction and any one variable studied is not identified. The major contribution of the study lies in the descriptive detail and in ruling out any one characteristic as "the one variable" that really matters in determining satisfaction among grandparents.

The purpose of this investigation is to determine whether or not Denton County gained or lost from the construction of Lake Dallas from the tax valuation standpoint.

"The purpose of this study is to examine the impact of the medicare law on a particular hospital: Flow Memorial Hospital, Denton, Texas. The scope of this study is limited to an analysis of changes in hospital car at Flow Memorial Hospital resulting from medicare. These changes are examined on the basis of 1. number of patients and days of care; 2. hospital services by department; 3. the means of payment; and 4. social characteristics of the aged patient group. A detailed examination of aged patient care was made for the fiscal years 1966 and 1967. The 1966 year was the year immediately preceding medicare. The 1967 year was the first year of medicare. Longer time periods were used where the data were available and pertinent."-- leaf 1.

"The problem of this study is to determine whether the hobbies of the fourth and fifth grade boys of the public schools in Denton, Texas, are contributing to their social needs. It is believed that the intangible attributes of living, which can be mearsured neither by rule nor square, make for the well-rounded, happy, social, individual, whether he be adult or child. The degree to which an individual is adjusted socially ranges from the completely anti-social type to the fully-integrated type. The reasons for this gradation are numerous. They include the influence of the home, the school, and the playmates, as well as other factors in the general environment of the child. The purpose of this investigation is to discover whether the hobbies of the boys under consideration are potential and actual forces for integration and socialization."--leaf 1.

"The first part of the study is devoted to a comparison of those graduates who stay in Denton with those who move away. The marital status of each group, where they live, and why they chose the cities in which they live are shown in this section. A study is made to determine if those graduates who have moved away choose cities larger or smaller than Denton. The second aspect of the problem is developed by making a comparison of the quality of work done in high school and amount of education of the two groups. To make this comparison, a study is made of the quartile rank in high school ; the number that attended college in each group; the schools they attended; and the number that graduated from college. The third part of the problem is a comparison of the degree of success attained by each group. the occupations of the graduates, the number who have their own businesses, the financial success of each group, and the relationship of education to financial success attained are shown. The fourth division of the problem is the presentation of suggestions given by the graduates for improving job opportunities in Denton. It is hoped that this study will show whether or not Denton is losing its potentially more valuable citizens to other communities."-- leaf 2.
