A Historical Study of Agricultural Education with Special Application to Denton County (open access)

A Historical Study of Agricultural Education with Special Application to Denton County

In this study the activities contributing to the welfare of the farmers of Denton County will be confined to the experiment farm or station and the county extension service. These two educational agencies have proved that adult education can be very successful. Although there is no direct relation between the two, most of the information learned in experimental research is imparted through the extension service.

The Social and Economic Implications of Education in the Civilian Conservation Corps (open access)

The Social and Economic Implications of Education in the Civilian Conservation Corps

"The purpose of this study will be to picture the three-fold aspect of the C.C.C. educational program. This will be done in five chapters. This, the first chapter, will describe the conditions leading up to the creation of the C.C.C. It will show how education became the prime motivation of the whole C.C.C. and it will show how the permanency of the C.C.C. depends on the type of education that is evolved. Then, chapters two, three and four will analyze the three phases of C.C.C. education. These chapters will be concerned with (1) leisure time activities, (2) vocational education, and (3) academic education. The final chapter will deal with the social and economic results of the three-fold educational program in the C.C.C. Through the entire study there will be a definite attempt to establish certain results and to evaluate them according to the gains that have been made in C.C.C. education since the beginning in 1933."-- leaves 1-2.

A Comparison Between the Programming Processes of the Instructional Services Division, KERA-TV, Dallas, and the Instructional Television Center, Israel (open access)

A Comparison Between the Programming Processes of the Instructional Services Division, KERA-TV, Dallas, and the Instructional Television Center, Israel

This paper compares the different approaches to programming taken by KERA--TV Instructional Services Division and by Israel's Instructional Television Center This study first examines the historical development of instructional television in the United States, particularly in Dallas, and in Israel, Next examined are the differences and the similarities between the stations' programming processes. Finally, the study examines the perceived achievements of programming goals set by each station. This report concludes that the stations' differences in their approach to programming are rooted in their historical developments, and discusses the opposite directions which the stations' programming processes are currently developing,

A Characterization Of Jackson Blue Spring, Jackson County, Florida (open access)

A Characterization Of Jackson Blue Spring, Jackson County, Florida

Jackson Blue is a first magnitude spring in the karst terrane of northeast Florida. Previous studies have identified inorganic fertilizer as the source of high nitrate levels in the spring. Agricultural land use and karst vulnerability make Jackson Blue a good model for conservation concerns. This work offers an aggregation of studies relating to the springshed, providing a valuable tool for planning and conservation efforts in the region. An analysis of nitrate levels and other water quality parameters within the springshed did not reveal significantly different values between agricultural and forested land use areas. Confounding factors include: high transmissivity in the aquifer, interspersed land use parcels, and fertilizer application in forested areas due to commercial pine stand activity.

Use of geographic information systems and infrared-triggered cameras to assess white-tailed deer (Odocoileus virginianus) habitat in Denton County, Texas. (open access)

Use of geographic information systems and infrared-triggered cameras to assess white-tailed deer (Odocoileus virginianus) habitat in Denton County, Texas.

This study utilized geographic information systems, remote sensing, and infrared-triggered cameras to assess white-tailed deer habitat in Denton County, Texas. Denton County is experiencing tremendous growth in both population and development. Despite their presence here historically, white-tailed deer were all but extirpated by the beginning of the 20th century, and there are no data available which support their presence in Denton County again until the 1980's. This study attempts to equate the increase in white-tailed deer population to Denton County's transformation from an agricultural to an urban economy and lifestyle. Eighteen sites were chosen throughout the county to research the following metrics: geology, soils, landcover, landscape ecology, streams, shorelines, land use, population, roads, structures, and census methods.

Plastics, Their History and Use (open access)

Plastics, Their History and Use

Since the civilization, population and living standards of the peoples of the world have increased in such gigantic proportions, especially in the last fifty years; and since the supply of natural resources cannot meet the demand, we have of necessity had to find new materials to take their place. These new materials must fulfill two purposes; namely, to take the place of the natural resources so wantonly destroyed and to meet requirements that the natural materials are not able to meet. Foremost among these new materials are the synthetic resinous materials known as plastics. Plastics are one way of getting around the fact that Nature has not thought of everything. The ability of man to imagine things that he does not see and to fashion these things from what he finds around him is responsible for what we call progress -- and for plastics.

Effects of Water Source, Suspended Solids, and Acclimation on Biotransformation of 2 /4-Dichlorophenoxy Acetic Acid in Aquatic Systems (open access)

Effects of Water Source, Suspended Solids, and Acclimation on Biotransformation of 2 /4-Dichlorophenoxy Acetic Acid in Aquatic Systems

In recent years there has been a great deal of scientific interest in processes that affect the fate of organic chemicals in the environment. one main reason for this increased interest is due to greater environmental concern over accidental or purposeful release of these chemicals into the environment by man. A major environmental concern is the increased use of pesticides over the last few years. In the thirty years prior to 1978 the use of pesticides has increased by a factor of forty (Ridgeway et al., 1978). Recently the use of herbicides has been increasing, but that of insecticides has stabilized (Willis, 1983). Detectable amounts of organic pesticides can be found in many areas of the biosphere. For toxic organic chemicals to be used safely, researchers must have a clear understanding of the fate and persistence of these chemicals when they are released into the environment. This understanding will also allow the development of new products that, when properly used, will not produce adverse effects to man or the environment (Weber, 1972). According to the Toxic Substance Control Act (TSCA) any new or expanded-use chemical that might be released into the environment must be tested for environmental hazard.

A Method of Filming a Music and Fine Arts Program (open access)

A Method of Filming a Music and Fine Arts Program

In reviewing the events of the advances of science and technology of the past two decades one is struck by the magnificence of man's accomplishments. The first moon walk televised live in 1969, the widespread utilization of color television receivers, the educational uses of sophisticated audio-visual equipment such as overhead projectors, slide projection, sound tape recorders, close-circuit television and videotape and the almost omniscient usage of television, is ample evidence to demonstrate that the tools necessary to accomplish a task are readily accessible items in this age. We are introduced to new gadgets, innovations, and events (like the moon walk) at such a rapid pace that we have become more flexible and more receptive to change; so much so that at times many of us are even blase about nearly miraculous accomplishments.
