Determining the need for and making plans for establishing a terminal vocational agricultural program at Hiwassee Junior College

The Problem The problem is to determine the need for, and make plans for establishing a Terminal Vocational Agricultural Program at Hiwassee Junior College. Importance of the Study The writer has been employed as a teacher in the agricultural program at Hiwassee Junior College since 1949. The agricultural program has been of a general nature with no clear cut objectives that have been accepted by the teacher and the administration. No study had been made to clearly show the need for the program or the kind of program it should be. The problem arose from this situation. Therefore, the writer needed to solve these problems in order to put the program on a sound basis. The administration felt there was a need for a Terminal Vocational Agricultural training program. It encouraged the writer to make the study and was willing to give all the help possible. Definition of Terms Junior College for this study will mean an institution offering the first two years of college work. This is through the sophomore year. Terminal is interpreted to mean the formal coursework ends with completion of the sophomore year. This work is not designed for transfer to a senior college or university. The term vocational pertains to an occupation in this study. It refers to the occupation of farming or employment in related fields of agriculture. Related fields of agriculture are those areas of occupation in jobs not directly in the business of farming but giving service to the business of farming. Terminal vocational agricultural program is a course of work planned to prepare the student for gainful employment in his chosen area. This training combines the classroom work with actual participation on the job. Service area is that area from which students come and the college gives its services. Scope and Limitations This study is limited to a vocational agriculture program at Hiwasaee Junior College. This program is on a two year basis for all day classes. This study is on vocational program not vocational and general. Assumptions The following are some assumptions made by the writer: There is a place for junior college. 2. There is a place for agriculture in junior college. 3. Vocational approach is better than general. 4. This program should be tied in with the college farm. Procedure for the Study The writer made surveys of high school vo-ag seniors in twenty-four counties of east Tennessee to help establish the need for the program at Hiwassee Junior College. This survey was to determine interest in this kind of program. Surveys were made of prospective employers, farmers and men in related fields to determine their Interest in this program. The writer made a study of some related studies in this area to secure additional evidence of need for the program. The college policies and attitudes of the college administration were studied to find if there would be conflicting purpose in the college policy and the purpose of this kind of program. Surveys were made of other junior colleges having this kind of program or similar programs, to find their purposes and objectives, and also their administrative and supervisory procedures. The writer had conferences with the administration of the College to determine its attitude and opinion of a program of this kind. The history and purpose of the College was studied to determine the degree of compatibility between them and a vocational agricultural program. The findings relating to a need for the program are found in Chapter II. Through much reading and study the writer formulated some principles that were believed sound for guiding the planning and establishing of a program of this kind. These principles formed a construct for the program. Chapter III is this construct. The construct served as a guide in making plans for the planning and establishing of a program at the College. This plan is found in Chapter IV. The study and planning of this work revealed a great need for further study in this field of education. Some of these needs are to be found in Chapter V of this study

LAPR: An experimental aircraft pushbroom scanner

A three band Linear Array Pushbroom Radiometer (LAPR) was built and flown on an experimental basis by NASA at the Goddard Space Flight Center. The functional characteristics of the instrument and the methods used to preprocess the data, including radiometric correction, are described. The radiometric sensitivity of the instrument was tested and compared to that of the Thematic Mapper and the Multispectral Scanner. The radiometric correction procedure was evaluated quantitatively, using laboratory testing, and qualitatively, via visual examination of the LAPR test flight imagery. Although effective radiometric correction could not yet be demonstrated via laboratory testing, radiometric distortion did not preclude the visual interpretation or parallel piped classification of the test imagery

The benefits of expediting government gold sales

Additional gold can be made available either by mining at high cost (approximately $250 per ounce in 1997 dollars) or by mobilizing government stocks at zero cost. Governments own massive above‐ground stocks but loan out only a small percentage of these stocks. Making all government gold available for private uses immediately through some combination of sales and loans maximizes total welfare from private uses, a consequence of the first welfare theorem. We simulate a calibrated version of our model to quantify the effects of liquidating government stocks on alternative dates. If governments sell immediately rather than never, total welfare increases by$340 billion; if they make an unanticipated sale in 20 years, $105 billion of that amount is lost. By depressing prices, such sales benefit depletion and service users but injure private owners of stocks above and below‐ground. However, the injury to above‐ground stock owners is more than offset by the benefits to service users—often the same individuals. Mine owners would be the principal losers; however, they could be compensated (twice over) from government sales revenue without any need for tax increases.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/142282/1/rfe235.pd

A Moment in Archaeology: A Reflexive Examination of the Culture of Meaning-Making in Archaeological Fieldwork

To many, archaeology is a science. It is not, however, a traditional laboratory science with controls and variables. Its experiments cannot be repeated and its variables cannot be controlled so much as managed and standardized. This regulation in archaeology has, until recently, attempted to eliminate human error, indeed, the human experience from fieldwork. Though the experiences I had in Indiana and Kenya could not have been more different, the control and regulation in archaeological fieldwork attempts to minimize the importance of those differences

Identifying dynamical modules from genetic regulatory systems: applications to the segment polarity network

BACKGROUND It is widely accepted that genetic regulatory systems are 'modular', in that the whole system is made up of smaller 'subsystems' corresponding to specific biological functions. Most attempts to identify modules in genetic regulatory systems have relied on the topology of the underlying network. However, it is the temporal activity (dynamics) of genes and proteins that corresponds to biological functions, and hence it is dynamics that we focus on here for identifying subsystems. RESULTS Using Boolean network models as an exemplar, we present a new technique to identify subsystems, based on their dynamical properties. The main part of the method depends only on the stable dynamics (attractors) of the system, thus requiring no prior knowledge of the underlying network. However, knowledge of the logical relationships between the network components can be used to describe how each subsystem is regulated. To demonstrate its applicability to genetic regulatory systems, we apply the method to a model of the Drosophila segment polarity network, providing a detailed breakdown of the system. CONCLUSION We have designed a technique for decomposing any set of discrete-state, discrete-time attractors into subsystems. Having a suitable mathematical model also allows us to describe how each subsystem is regulated and how robust each subsystem is against perturbations. However, since the subsystems are found directly from the attractors, a mathematical model or underlying network topology is not necessarily required to identify them, potentially allowing the method to be applied directly to experimental expression data

Delineation of Soil Boundaries Using Image Enhancement and Spectral Signature Classification of Landsat Data

The concept of using satellite data for soils inventories began with the advent of the first ERTS launch in 1972. Landsat data can be useful in a field survey, if it satisfies one or both of two requirements: the products must improve the accuracy of the survey and/or it must expedite the survey. These goals can be achieved by creating products that enhance and delineate soil surface features that would not necessarily identify specific soil types but rather provide a spatial boundary that a field scientist could observe and evaluate. A 250,000 acre tract of semiarid rangeland in east central Utah was selected as the study area. A June 13, 1977 Landsat scene was chosen for analysis. The color composite combined with such ancillary data as geologic maps and topographic quadrangles aided in partitioning the study site in to areas of physiographic homogeneity. A principle components transformation was performed on the data and a uniform contrast stretch was applied to the unaltered spectral bands and the transformed axes. The contrast stretch increased the dynamic tonal range of the data, and created as many as 32 different tonal classes. Various color combinations and a number of density slices were evaluated for their interpretability. A spectral signature classification of the June scene was developed using both supervised and unsupervised classification algorithms. A canonical analysis was then performed on the thematic maps to improve class separability for image enhancement. The more promising image products were geometrically corrected, scaled to 1:24,000, and merged with data digitized from a partially completed soils map. The resulting map allowed comparisons between soil lines drawn by a field soil mapper and the classes defined by computer analysis. Both the enhanced images and the spectral classification maps aided in the delineation of soil boundaries. Enhanced images are inexpensive to generate and, as no subjective class groupings are made, have the added quality of objectivity. The spectral classification maps defined surface characteristics that could be used to help separate soil units. A cost analysis for the individual products and an indepth field evaluation is being completed
