The Cost Of Owning And Operating Farm Power And Machinery Used In Tillage Operations On Diversified Farms In Selected Areas Of Utah, 1960, Clynn Phillips

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A current problem facing farmers is, how much should they mechanize their farm perations? As the relative price and productivity of factors change farmers usually have to adjust their operations to assure maximum profits. Technological advances often change the relative productiveness and the price of machinery. These changes have caused the progressive farmer to continually review his farm organization and make adjustments in levels of factor use. If he is to produce at maximum profits it is necessary that his machinery investment be in proper adjustment with other resources.

Student Teacher Attitudes Toward Child Aggression And Dependency In A Child Development Laboratory, Kristine Halls Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A child development laboratory in a university finds its first justification in its ability to contribute to the education of college students. After this justification has been established, the laboratory has a responsibility for serving the children enrolled in it.

The Child Development Laboratory at Utah State University serves college students in several ways. Students are able to observe and participate in the nursery school laboratory through experiences in various courses. The culmination of their course work comes when, as juniors or seniors, they do student teaching in the nursery school.

Some of the purposes the nursery school attempts to …

Comparative Marital Adjustment Of A Selected Sample Of Active And Inactive L.D.S. Church Members, Paul K. Winward

The couples were selected from the geographic areas of Enterprise and Logan, Utah, and Preston, Idaho. Respondents consisted of couples who had at least one child, but no children beyond high school age. Their religiosity was determined by the bishop of the L.D.S. Ward of which they were a member. The bishop considered such factors as attendance at regularly scheduled church meetings and contributions made in the form of tithes in determining whether a couple was considered active or inactive. The sample consisted …

Differences In Frustration Reactions Of Nursery School Children, Sharon Marshall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The study of frustration has been of interest to various people including psychiatrists, psychologists, and educators for a number of years. These people have been interested in frustration because the complexity of our modern life has involved so many frustrating experiences. Frustration has been defined by Dollard (8, p. 7) as "an interference with the occurrence of an instigated goal response at its proper time." Ruch (21, p. 151) defined frustration as "the denial or thwarting by some obstacle which lies between a need and its goal." These two definitions are in essence identical. The average person has many obstacles …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Body weight is fast becoming the major health problem in the United States. Recent estimates of the number of weight conscious people in the United States are now up to 75 million. One year ago the estimate of overweight individuals was 60 million Americans who were overweight or should be concerned about watching their weight. There are also two million known diabetics who must control their disease and body weight by a restricted caloric intake.

An Evaluation Of Social Stars, Regulars, Neglectees, And Isolates In Ability-Grouped And Random-Grouped Classrooms, Benjamin W. Standing

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Education in the United States attempts to present maximum opportunities for learning in a democratic atmosphere. Many great educators have sought means to accomplish this end. Today, because of the stimulating force of other nations, even greater pressure is being brought to bear to achieve these goals. The plan of grouping pupils according to their abilities has been presented as one way to facilitate learning.

Ability grouping is the assigning of pupils who are essentially alike to special grade levels and to parallel sections of the same grade. Although it may be thought that ability grouping is a new procedure, …

Educational Grouping And Students' Self Concept, John N. Giboney

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The question of ability grouping in education has achieved prominence, especially in recent years. Much of the emphasis placed on grouping students according to ability rather than chronological age is a product of modern times and progressive education. Although not accepted by all educators, there is a definite movement toward such a procedure in public schools today. It is held by the advocates of ability grouping that students will benefit more in a situation where they proceed at a rate prescribed by their ability rather than a hypothetical average or norm. Several well-controlled studies (3, 33, 44) have shown that …

An Analysis Of The Achievement Gains Made By Students In Ability-Grouped Vs. Random-Grouped Classroom Units, Luan H. Ferrin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Because of the rapid advancements being made in the field of knowledge, educators, as well as those in other fields, must periodically take inventory. Current practices, policies, and methods must be carefully scrutinized to determine if they are the most effective. The group or class method of instruction is one such area.

A Comparison Of Underachievers And Normal Achievers At The Upper-Elementary And Seventh-Grade Level, M. Nephi Manning

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

That each is born with differing capacities and potentials is self-evident. Both students and teachers should accept as their right and duty the task of bringing to full fruition these latent potentialities.

It is a cause of concern in the nation, among parents and teachers, and in later years among students themselves, that many of our youth fail to achieve that of which they are capable. This is a loss to society and a disappointment to the individual.

The purpose of this study is to add to the growing fund of knowledge concerning factors related to this important area of …

An Evaluation Of Antibiotics Upon Selected Dairy Organisms, Roy Brog

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was designed to answer a three-fold purpose. Primarily, it has endeavored to measure the inhibitory effect of three antibiotics (potassium pencillin, dihydrostreptomycin, and oxytetracycline) on lactic acid producing organisms. The lactic acid-producing organisms include Streptococcus lactis, Streptococcus thermophilis, and Lactobacillus bulgaricus.

The determination of an effective dose of a given antibiotic which will inhibit 50 percent of the lactic acid-producing organism (E.D.₅₀) will be established. A 50 percent cut in acid development will certainly lead to an inferior product.

The secondary purpose has related to the detection of inhibitory substances (antibiotics) in milk. What is …

A Study Of The Use Of The Hydrogen Peroxide-Catalase Treatment Of Milk In The Manufacture Of A Reduced Fat, Cheddar-Like Cheese, Lamar John Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nutritionists, the medical profession, and the public in general have become increasingly interested in low fat food products. Cheddar cheese, as it is now made, has a high caloric value and therefore may be discriminated against in some diets. The production of a reduced fat cheddar-like cheese would be of importance to the cheese industry by providing a reduced fat, high protein product.

The chemical nature of the casein furnishes the foundation for the body and texture in cheese. The body and texture of typical cheddar cheese is influenced principally by its fat and moisture content.

The use of hydrogen …

Income Adjustments From Fee And Permit Changes On Utah Cattle Ranches Using Public Ranges Yearlong, C. Kerry Gee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Within the boundaries of Utah are approximately 52.7 million acres of land. About 41 million acres are rangeland, of which 73 percent is federally owned and 5 percent state owned (6).¹ The portion owned by the Federal government is administered by the Bureau of Land Management (BLM) and the Forest Service. Most of this land is either arid or mountainous and has been used mainly for grazing in the past. IT has other uses, however, such as mining, forestry, recreation, and watersheds. Due to recent increases in population, personal income, shorter work weeks, and improved transportation facilities, these alternatives …

Complexing Of Sugars And Polyhydroxy Alcohols With Molybdenum (Vi), Su Chin Kiang

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Molybdenum is very important in the life processes of both plants and animals. It acts as a catalyst in promoting and controlling many biological reactions in living cells, but exactly what it does and how it functions are not well understood. In the past because of the obvious complexity of the reactions concerned and the extremely minute quantities of molybdenum involved, its presence was long undetected. Lately, molybdenum has drawn special attention on account of its effects on metabolic processes, particularly of plants. In this regard, molybdenum has been shown to be present in four enzymes: nitrate reductase (JJ), xanthine …

A Matrix Formulation Of The Least-Squares Method And Its Application To Nuclear Decay Schemes, Otto Harry Otteson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many people call physics an ''exact science". This may be true depending on our definition of exact. Most dictionaries include as a definition of exact the words "strictly accurate". The average man thinks of an "exact science" as one which yields "strictly accurate'' results. Physics then is exact only to a degree.

History Of The Church College Of Hawaii 1955-1960, Ralph Dallas Olson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

From the Mormon point of view, ignorance is a sin. Mormons believe that their very salvation is dependent upon the development of their mental and spiritual powers, as evidenced from the two following, typical statements from Mormon sacred literature: "The glory of God is intelligence;" "It is impossible for man to be saved in ignorance."

A Determination Of The Earth's Gravity Field In Spheroidal Coordinates, M. Spencer Hamilton Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The earth's gravity field G * at a point P in the region surrounding the earth's surface is defined as the force acting on a unit mass concentrated at P. This is a force resulting from two components: (1) G₁ due to the gravitational attraction of the earth's mass, and (2) G₂ due to the earth's rotation.

As a result of Newton's law of gravitation, G₁ can be written in integral form as follows:

G₁ = k ( (_V ( rdm/r³

where r = PQ, r = |r|, Q is a point which ranges …

The Teaching Machine As A Study Aid At The College Level, John R. Cragun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

One of the most interesting and challenging problems to confront those interested in the learning process in recent years is the entire area of the self-instructional device, or "teaching machine." The idea of the teaching machine is not new, for Pressey (49) in 1926 wrote concerning a device he had developed, and at the same time indicated that he had had such a device in mind for "a number of years." After this introduction by Pressey, the teaching machine movement lay dormant for several years with only an occasional article written that had any direct relationship to this area. This …

Content, Sequence, And Emphasis Of Arithmetical Concepts As Presented In Six Textbooks And An Analysis Of Student Errors In Fifth Grade Arithmetic, Lorenzo Groutage

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Arithmetic problems and the mastery of such problems play an important role in society as it exists today. The pressure from the public has been and is for better teaching of the basic skills. Public school teachers have often evaded this issue (2). For the past decade the emphasis has been "Why Johnny Can't Read," but it seems equally important, because of the relationship of reading and arithmetic, that the focus also center on the mathematical phase of educa­tion (8).

Deviations In Serum Proteins Associated With Eimeria Bovis Infections In Calves And Some Related Immune Reactions, Paul R. Fitzgerald

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Bovine coccidiosis is a serious threat to the economy of the cattle industry in the United States. In 1954 the United States Department of Agriculture reported that over $10,000,000 was lost annually as a result of mortality and morbidity in cattle due to this parasite (1). These losses alone amounted to more than one fourth of the total loss in cattle due to parasitism.

Pfaffian Differential Expressions And Equations, K. Raman Unni

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

It is needless to point out the necessity and the importance of the study of Pfaffian differential expressions and equations. While it is interesting to consider from the pure mathematical point of view, their applications in many branches of applied mathematics are well known. To mention a few, one may observe that they arise in connection with line integrals (example, determination of work). They provide a more rational formulation of the foundations of thermodynamics as developed by the Greek mathematician Caratheodory. They also arise in the problem of determining the orthogonal trajectories. In many branches of engineering and other physical …

The Effects Of Certain Environmental And Biological Factors On Rally Calling In The Chukar Partridge, H. Warrington Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Naturalists for many years have known that birds sing most at dawn and at dusk, but to which of many physical variables they are responding has not been completely determined. This problem has taken on importance in the field of wildlife management because calling rate has been used as an index of abundance for numerous game birds, namely the Pheasant, Phasianus colchicus (Kimball, 1949); the Mourning Dove, Zenaidura macroura (McClure, 1939); the Bobwhite Quail, Colinus virginianus (Bennitt, 1951; Rosene, 1957): and the Woodcock, Philohela minor (Pitelka, 1943).

The Weston Canyon area comprises the southern part of the Bannock Range and northwestern part of the Malad Range in southern Idaho. Geologic investigations of adjacent areas date from 1871. These investigations have led to detailed geologic reports that cover much of the Wasatch Range, Bear River Range, Malad Range, Portneuf Range, and Cache Valley. The geology of the southern part of the Bannock Range, however, has not been studied in detail, and it is the purpose of this investigation to map and describe the geology of the Weston Canyon area and to correlate it with previously described geology of …

A Study Of The Homeroom Program In Three Senior High Schools In Utah, Ida D. Draayer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The function of the secondary school is to help each individual develop and direct all of his potentialities. It should seek to help boys and girls find their rightful places as citizens in a democratic world. The fact that each individual is different presents a distinct challenge, and the secondary school is capable of meeting this challenge of individual development if the homeroom functions as it should.

An Introduction To The Ethology Of The Uinta Ground Squirrel (Citellus Armatus), David F. Balph

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study describes behavior of the Uinta ground squirrel (Citellus armatus) in a free-living population. Its objective is to provide basic behavioral information on a small mammal which can fill in part of the gaps in our knowledge of behavior and social organization of the vertebrates. This would contribute to the long-term goal of viewing the progressive evolutionary changes in behavior from lower forms to man.

The Influence Of Water-Reducing Admixtures On The Curing Of Concrete, Wallace Don Budge

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The use of water-reducing admixtures in concrete has grown continuously since their introduction over 25 years ago, with a present estimated usage in the production of 25 million cubic yards of concrete annually in the United States alone. Opposition to anything added to concrete, other than cement, aggregates, and water, is gradually disappearing, and considerable recognition is being given to the value of using other ingredients.

The research contained in this study may be divided into two portions: tests to determine the rate of volume change of cement paste and compressive strength tests to indicate the effect of moist curing …
