Life History And Habitat Utilization Of Merriam's Turkey In Southwestern Utah, Fred C. Bryant

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study of the Merriam's wild turkey was conducted March 1972 to August 1973 in southwestern Utah to determine the life history and habitat utilization. Using transects, bio-telemetry, and observational techniques, information on flocking, hen:poult and sex ratios, and approximate dates for spring dispersal, nesting, and hatching was obtained. Turkey observations in relation to habitat variables were used to determine habitat utilization.

Except during the spring mating season, male flocks remained apart from other turkeys. Hen flocks in fall and winter consisted of adult hens and juveniles of both sexes. Males dispersed from winter flocks in March, and those that …

An Analysis Of Selected Factors Related To Job Satisfaction As Determined By A Survey Of Business Teachers Employed In Utah Public High Schools, Patricia Dianne O'Reagan

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Origin and nature of the problem

Work is an important aspect of the total life experience. It has been estimated that man spends a total of one-third of his waking hours each week engaged in some type of work.

As an important aspect of life in our culture, satisfying work contributes to man's sense of general well-being and feeling of personal worth. Work that is not personally satisfying tends to have the opposite effects. (25, p. 329)

The above quote, taken from Siegel's Industrial Psychology, discusses an important problem in this age of technology--job satisfaction.

Several personal characteristics have been …

Implementation Of Previous Research On Competency-Based Practicum In Special Education At Usu, Clifton W. Jenkins

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

There is a very real need for exploration and development of alternative approaches to special education (Lilly, 1971). Some have questioned the necessity of teachers receiving preservice training at teacher education institutions (Popham, 1971). Schwartz (1971) suggested that teachers need special training before being placed in a diagnostic-prescriptive teaching situation.

The recent trend is to integrate the special student into the regular classroom. This requires that special educators be trained to perform specialized assessment and provide remedial instruction for a variety of exceptional children in a way that is compatible with regular classroom routine and procedure (Burrello, Tracy, and Schultz, …

A Comparison Of Extant Articulated English Programs With Current Articulated English Program At Bonneville High School, Utah, Wilford M. Hale

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Throughout the decade of the sixties, teachers, administrators, curriculum writers and text book companies have all made vigorous attempts to redefine the teaching of English. Teachers have organized themselves on local, state, and national levels to concentrate their efforts and share their knowledge. In part they have been responsible for some of the current trends: better preparation of teachers, experimentation with new methods in the classroom, and more consistent evaluation of what is taking place in the classroom-what teachers teach and what students learn.

The Implementation Of Career Education In The General Business Classes Of Cache County Junior High Schools, Katie Graham

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Career education is the goal of the seventies; the direction education will take, and the force that can give new meaning to all teaching techniques and classroom Instruction. More significantly, career education is the new power that can change for the good the lives of all students by assuring that every young person completing high school would be ready to either enter higher education or to secure useful and rewarding employment (17, p. 21). However, as emphasized by May, career education is on the launch pad and the count down has started, but the ultimate responsibility for getting career education …

Interactive Hybrid Computer Program As An Aid For Teaching Hydrology, Arif Hikmet Atali

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The science of water resource planning and management implies the utilization of available water supplies in order to meet specific goals and objectives (Hill and Riley, 1972). Essential to effective planning and management is the consideration and analysis of all possible alternatives. Past research at Utah State University has demonstrated that the hybrid computer simulation of hydrologic processes is a reliable planning technique which provides the capability to examine many possible alternatives in a short period of time (Hill et al., 1970; Riley, 1970; and Riley et al., 1967). This technique, because of its interactive characteristics, is valuable also in …

A Longitudinal Study On The Effects Of Stopping Out, Robert Dean Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Inquiries have been made by the Carnegie Commission on Higher Education and the United States Department of Health, Education, and Welfare to determine how colleges and universities could meet the financial crisis now being faced. One of the recommendations made by both agencies as a result of their investigations was that curriculum planners at these institutions provide students with opportunities to have off-campus experiences, preferably in their chosen career areas, before they are graduated to determine whether they want to pursue their studies in that area or reorient themselves to other options. These planned stopouts, they suggested, would curtail drifting …

Determination Of Optimum Quality In Ground Turkey Formulation, Juntip Chongdarakul

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ground turkey samples were prepared with different fat levels, fat types, percent mechanically deboned meat and grind. All samples were analyzed at three different time-intervals. Samples were evaluated by chemical, sensory, and physical measurements, in term of stability, water content, fat content, press fluid, water loss, flavor, texture, and hedonic values. Significant differences were determined by analysis of variance.

Coarse ground (5/8") samples showed significantly higher TBA numbers, fat content, total loss, and juiciness. Water content, flavor scores, amount of press fluid, texture scores, and hedonic scores were lower when compared to the fine and medium ground samples.

Results of …

Extractable-Emulsifying Capacity Of Hand And Mechanically Deboned Mutton And Organoleptic Acceptability Of Various Mutton Salami Formulations, Jack Robert Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Salt soluble extracts from mechanically deboned mutton were significantly higher (P < .01) in pH than the extracts from the hand boned mutton. An associated trend toward greater extractability, however, was not significant. Variation in emulsifying capacity between extracts from carcass parts were highly significant yet significant variation did not occur in the emulsifying capacity of hand versus mechanically deboned mutton. A new term, extractable- emulsifying capacity is presented which incorporates the extractability and emulsifying capacity of meat extracts into one value which should more accurately estimate the contribution of a meat ingredient in forming a stable sausage emulsion.

Salami, utilizing mutton, was formulated from experimental results which indicated that up to 10 percent mutton fat and 68 percent mutton lean was acceptable to panelists. Pork was preferred to beef for use in combination with mutton as determined by panel scores, however disagreement was noted between panelists. Panelists were unable to detect flavor, moisture or texture differences between the final mutton salami and a commercial beef and pork formulation. They did however prefer the appearance of the mutton salami (P < .05).

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Whole milk acidified to pH 5.3 with hydrochloric acid was used for the manufacture of Monterey cheese. The milk was inoculated with one and one-half percent lactic starter and set with 12.5 ml rennet per 1000 pounds of milk. Normal washing treatments resulted in cheese with moisture in excess of 44 percent. Moisture content was brought below 44 percent by using wash water at a temperature such that the water-curd-whey mixture was 35 C. The pH of cheese made by preacidification was all between 5.21 and 5.09. No acid defects were encountered. Preacidification eliminated chance of spoilage or losses caused …

Effects Of X-Ray Induced Achlorhdria On The Utilization Of Dietary Calcium And Iron From Different Salts By Rats, Reid Scott Holbrook

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dietary calcium has been classified as one of the minerals frequently limiting in the American diet (FAO, 1962) . Bone demineralization has been observed as a result of calcium deficient diets (Salomon et al., 1972), partial gastrectomies (Eddy, 1971) and inadequate hormonal balance (Albright et al., 1948). Although bone demineralization, or osteoporosis, has been attributed to many factors, the interrelationship of gastric acidity and the utilization of dietary calcium may be a key to the etiology of osteoporosis.

Eighty weanling male albino rats were divided into eight groups. All animals had their stomachs exposed through a mid-line incision. Control rats …

Formation And Anatomical Distribution Of Chlorophyll And Glycoalkaloids In Potato (Solanum Tuberosum L.) Tubers And Their Control By Physical And Chemical Treatments, Robert Bruce Jeppsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Applications of growth regulators and modifications of light exposures were investigated regarding their abilities to curtail the normal development of chlorophyll and glycoalkaloids in potato tubers responding to light. Four growth regulators were sprayed on the foliage of potato plants 14 days prior to harvest, of which two (Ethephon and N⁶-Benzyladenine [N6BA]) successfully retarded chlorophyll and glycoalkaloids in the harvested tubers. When tubers were dipped in N6BA, lower concentrations of the chemical promoted glycoalkaloid formation, while larger amounts were more inhibitory. When fluorescent lights were directed through colored cellophane filters, tubers receiving yellow and orange illuminations were inhibited …

Resource Allocation And Factor Substitution In Guayas Basin Rice Production, Gary Scott Glen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The primary objective of this study was to examine changes in resource productivity and factor shares as irrigation was introduced on small rice farms using traditional management techniques.

Average output on irrigated farms was double that of dry farms. This was because irrigated farms produced two crops as opposed to one crop on farms without irrigation. Examination of marginal products showed that farmers with irrigation could profitably use more land. Dry farmers could profitably use more labor. The low labor input and high MP of labor on dry farms occurs because these farmers are undercapitalized and are obliged to accept …

Intraregional Efficiency Of Production Decisions And Interregional Efficiency Of Input Use In Bolivian Agriculture, Stephen C. Hammond

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The main objectives of this study were to analyze the efficiency with which Bolivian farmers utilize productive resources as they combine them in crop production and to examine the possibility of interregional resource immobility in the production of agricultural products.

Bolivia was divided into seven distinct production regions called departments. A linear program maximizing model was generated for the major crops produced in each department. Land, labor, irrigation, and capital were the input coefficients used in the models. They produced a net return to management, land, and fixed costs associated with land. The linear program using these coefficients generated the …

In the visible region (0.4 to 0.7 micron) the average relative spectral transmissions under both canopies are about one percent beginning at 0.4 micron and decreasing to about half a percent at 0.67 micron. There is only a small peak in the green (0.55 micron) transmission under deciduous stands while there is none under coniferous canopies. The slightly higher transmission in the blue (0.4 micron) is attributed to …

Nutrition Of Sheep Grazing Foothill Big Game Range In Spring, Kurt J. Kotter

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Sheep with esophageal fistulas were used to determine the daily intake, nutritive content and digestibility of forage at three periods and two stocking intensities during the spring of 1972 on a typical foothill range in northern Utah.

Heavy grazing under a season-long regime did not influence the concentrations of dietary chemical components when compared to moderate grazing; however, it did depress the digestibility of cellulose and organic matter. There was a significant decline in the dietary chemical components due to forage maturation. Digestibility of organic matter and cellulose were significantly higher in the early spring as compared to late spring. …
