An Evaluation Of Truncated Sequential Test, Ryh-Thinn Chang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The development of sequential analysis has led to the proposal of tests that are more economical in that the Average Sample Number (A. S. N.) of the sequential test is smaller than the sample size of the fixed sample test. Although these tests usually have a smaller A. S. N. than the equivelent fixed sample procedure, there still remains the possibility that an extremely large sample size will be necessary to make a decision. To remedy this, truncated sequential tests have been developed.

A method of truncation for testing a composite hypotheses is studied. This method is formed by mixing …

A Study Of Four Statistics, Used In Analysis Of Contingency Tables, In The Presence Of Low Expected Frequencies, Jane R. Post

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Four statistics used for the analysis of categorical data were observed in the presence of many zero cell frequencies in two way classification contingency tables. The purpose of this study was to determine the effect of many zero cell frequencies upon the distribution properties of each of the four statistics studied. It was found that Light and Margolin's C and Pearson's Chi-square statistic closely approximated the Chi-square distribution as long as less than one-third of the table cells were empty. It was found that the mean and variance of Kullbach's 2I were larger than the expected values in the presence …

A Fine-Structural Study Of Aberrant Meiotic Cytokinesis In An Autosomal Male Sterile Mutant (Ms(2)3r) Of Drosophila Melonogaster, Laura J. Laughran

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The ultrastructure of abnormal meiotic cytokinesis in an autosomal male sterile mutant of Drosophila melanogaster is described. In the mutant ms(2)3R mitotic cytokinesis proceeds normally, but abnormal meiotic divisions give rise to four spermatids developing in one cytoplasmic mass. The contractile ring which is responsible for cell constriction during cytokinesis appears to form and function normally during meiosis. Ring canals which form intercellular bridges between synchronously developing spermatids are also apparently normal. However, there is an apparent adhesion and subsequent disintegration of the furrow membranes after division is completed. In addition to double membrane fragments in areas of open …

Nitrogen Fixation In Arid Western Soils, Robert Charles Rychert

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nitrogen fixation by blue-green algae-lichen crusts from South Curlew Valley, Utah, in the Great Basin Desert, was studied using the acetylene reduction technique. A molar ratio of 3 moles C₂H₄ produced/mole of N₂ fixed was used to estimate nitrogen (N₂) fixation by acetylene reduction. Nostoc was found to be present in many of the lichen thalli examined microscopically. Crust nitrogen fixation decreased rapidly below -1/3 bar pressure (water potential) which indicated that nitrogen fixation occurs only when the crust is wet. This would suggest that most of the crust nitrogen fixation in the Great …

A Comparison Of Second Grade Children's Learning Curves On School Tasks With Their Respective Performances On The "Black Box Test Of Learning Ability", Robert Stephen Knox

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study investigated the usefulness of the Black Box Test of Learning Ability as an indicator of children's performance on math and writing tasks. Twelve second grade students, seven to eight years of age, demonstrated naivete on both tasks and were subsequently individually administered the learning test. The subjects were divided into two groups, and each group received a different task presentation order. Composite scores were derived for all subjects and tasks, and individual learning curves were compared.

The combined Black Test score produced a significantly high correlate to math (rho = .733) and writing (rho = .841) than either …

An Evaluation Of The Effectiveness Of Parent Training Programs In Changing Parent Behavior, Betty Payne Janiak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effectiveness of two types of parent training were evaluated and compared with a control group that received training. A child Management Inventory was constructed for this purpose.

Parent Effectiveness Training was significantly superior to a training program developed by the Utah State Department of Education as measured by pre- and post-test criterion measure. There were no significant differences between the Utah State Department of Education group and the control group. This was determined by applying an analysis of covariance to the pre- and post-test data from all three groups. However, on a follow-up critical incidents test the Utah State …

The Influence Of A Nutrition Education Program On Preschool Children, Nida Diane Houston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A study on the influence of nutrition education experiences was conducted in the Child Development Preschool Laboratory at Southern Utah State College in Cedar City, Utah, with thirty-two preschool children. Sixteen of the children were exposed to nutrition experiences through food activities and stories.

It was found that the sixteen children who were involved in the fifteen nutrition experiences significantly increased their knowledge of nutrition concepts and further modified their own personal food choices. The control group, which was not exposed to nutrition activities, made no significant change in knowledge of nutrition concepts and no modification of personal food choices. …

Description And Research Study Of Four Effective Teaching Methods, Gail Ryan

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

During my years in the public school system, I have felt that a basic deterrent to the child's personal and emotional growth has been the inability of educators to effectively communicate with children in the classroom. Gordon (1970, p. 298) states that teachers and other adults "lack the basic attitudes and skills to be effective training agents in an interpersonal relationship with a child or adolescent." Flanders (1971) feels that teachers, while behaviorally influencing children and determining the learning situation, actually have little knowledge about those methods of influence.

I am concerned with the need to train teachers to work …

Tutorial Reading Programs In The Elementary School: A Survey, Judith P. Mitchell

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

In this complex and often confusing country, reading is viewed by many people as the most important skill a child can acquire during his school years. Success in school, of both children and teachers, particularly in the elementary grades, is often measured by children's success in learning how to read. Reading is the tool that unlocks most knowledge for children and adults alike. As a person seeks employment the inability to read or the inability to read with facility greatly limits the opportunities.

A Curriculum For The Manpower Stenographic Training Program At Utah State University, Karen Olsen Holman

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

Substantial numbers of the workers potential to the labor force-- especially those in the disadvantaged sector of the population--will require remedial and/or refresher job training in a wide range of occupations.¹

The Manpower Stenographic Training Program is a secretarial training course designed to enable female unemployed primary wage earners and heads of households to obtain this remedial and/or refresher job training necessary for entry-level positions in office occupations. Similar programs have operated at Utah State University since 1967 under the Manpower Development Training Act of 1962. The act was signed into law when Congress officially recognized the problem of …

Speech Improvement Programs In Rural And Urban Utah Public Schools: Kindergarten, First And Second Grades, Linda B. Crozier

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

Each year the public school speech therapist is confronted with large numbers of children having articulation problems. More often than not, the clinician is additionally faced with the task of selecting children with communication problems from among an extremely large population. By inspection, the list of children with articulation problems reveals a large percentage from the kindergarten, first and second grades who, if enrolled in a therapy program, would leave little time for children with problems in the upper grades.

The need for help with these articulation problems is felt almost universally by clinicians,Johnson (1967) indicated that as many as …

Recital Report, Robert Steven Call

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

It was the purpose of the recital to afford the performer an opportunity of developing overall musicianship and gaining insight into the teaching of brass instruments through the preparation and performance of several pieces of varied musical styles.

The writer elected to perform on trombone, baritone horn, and tuba. Successful performances had been done on trombone and baritone horn prior to the preparation of the master's recital. However, the tuba was a new performance experience because serious study of the instrument had only covered about one year.

The writer was specifically concerned with the selection of literature suitable to the …

Special Education And Pupil Personnel Services Offered By The Utah State Board Of Education, Mark J. Bankhead

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

In the United States responsibility for education is a function of the state, local school districts derive their authority from the state legislature (Graham, 1962). For many years, especially during the 19th century, the only legislative provision for the education of handicapped children was the limited support of state institutions and residential schools. Recent federal court decisions have substantiated the right of handicapped children to equal protection under the law, including an education, and made state departments of education "solely responsible for providing handicapped children with a free and public education appropriate to their individual capacities." (Abeson, 1972, p. 11) …

Residual Nitrogen As It Affects Soil Fertility Under Irrigated Agriculture In A Tropical Wet-Dry Climate, Don Carlos Kidman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the Zapotitan Valley near San Andres, El Salvador, Central America, an experiment was conducted to determine the availability of residual soil N to corn grown during the rainy season. This was an extension of an experiment conducted during the preceding dry season. The variables of the dry season experiment were irrigation method, crop, and rate of fertilizer N application. Soil NO₃-N and NH₄-N were determined by soil sample analysis to a soil depth of 120 cm by 30 cm depth increments. The samples were taken at the end of the dry season experiment and again …

Determining A Crop Production Function For Corn As Influenced By Irrigation And Salinity Levels, Timothy E. Sullivan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Production functions were generated for dry matter and grain yields of corn, A continuous variable plot design replicated four times was established in the spring of 1974 in Vernal, Utah. Each replication included ten salt treatments and twenty irrigation levels. The salt treatments resulted in an average root zone salinity ranging from 2 . 7 to 14.9 mmhos/cm. Irrigation levels ranged from 4.2 to 45.0cm of water applied. Dry matter (Kg/ha) yield showed an 83 percent reduction over the range of salt applied and a 52 percent reduction over the range of water applied. Grain yield declined 96 and 64 …
