The Micro-Characteristics Of Adult-Neonate Social Interaction, Ann Marie Berghout-Austin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In order to dissect social behaviors into their smallest components, five interactions, each involving one neonate and one adult, were video taped and kinescoped into 16mm black and white film exposed at 24 frames per second. The film was analyzed frame by frame and all starts, stops, and changes in direction of movements were scored. Adult movement durations were significantly shorter during vocalization and longer during nonvocalization. Each infant and adult body part had its own characteristic movement rate. Almost two-thirds of the dyadic movements were interactionally synchronous and most of the synchronization occurred during vocalization. It is suggested that …

A Self-Instructional, Multi-Media Approach To Facilitate The Teaching Of The Index Of Nutritional Quality, Claudia Kay Probart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A review of the literature dealing with nutrition education established the following: (a) that there is a need for nutrition education at the elementary school level; (b) that elementary teachers do not always have the background or motivation to meet this need for nutrition education; and (c) that new educational methods that are easier to understand and more highly motivating are needed.

The Index of Nutritional Quantity (INQ), a nutrient density concept, was developed at Utah State University to answer the need for easily understood and motivating nutrition information. The INQ method of nutrition education has been used and considered …

Projections are based on the method used by the bureau of the Census with certain modifications. Two sets of the population projects prepared by the Utah Agricultural Experiment Station, high and low medium, are chosen as the population base. By assuming the household formation pattern in two alternate ways, constant rates and exponential growth rates, two sets of household projections are prepared for each of the two sets of population projections. This study also makes some examinations on the social and economic implications of …

The Influence Of Various Factors On Nitrogen Balance And Protein Quality Measured In Adult Human Beings, Arthur John Wittwer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The effect of nitrogen intake, nitrogen source, calorie intake, body weight, adaptation time, research group and sex on the nitrogen balance of human adults was investigated. Data from studies reported in the literature were combined and analyzed statistically by multiple regression techniques. Analyses were made separately for six sources of nitrogen: egg, beef, rice, corn, wheat and wheat gluten.

Nitrogen intake, caloric intake and body weight exerted significant effects on nitrogen balance (5% level of confidence) for six, three and two of the six nitrogen sources, respectively. Other variables were not significant at the 5% level. Although differences were not …

Coyote-Food Base Relationships In Jackson Hole, Wyoming, John L. Weaver

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

I measured three variables of coyote-food base relationships in Jackson Hole, Wyoming, during the period July, 1973, to July, 1975. Field work provided estimates of relative coyote and prey abundance as well as observations on coyote feeding behavior during winter. Laboratory analysis of 1,500 coyote scats revealed feeding patterns while feeding trials with captive coyotes allowed refinement in interpretation of scat analysis.

Deer mice and chipmunks comprised most of the rodent biomass captured in traps in the fall, while ground squirrels accounted for much of the rodent biomass in the spring. Field voles declined from 1973 to 1974 throughout much …

Growth-Form-Analysis And Paleoecology Of The Corals Of The Lower Mississippian Lodgepole Formation, Bear River Range, North-Central Utah, Judith M. Miller

The Mississippian (Kinderhookian-Osagean) Lodgepole Formation contains a diverse fossil assemblage. Taxa present include brachiopods, crinoids, gastropods, cephalopods, trilobites and corals. Corals and associated fauna were collected from four localities within the Bear River Range. These are, from north to south, Beirdneau Hollow, Spring Hollow, Leatham Hollow and Porcupine Dam. The well-preserved tabulate and rugose (compound and solitary) corals exhibit a high degree of morphologic variability. The colonial corals of the Lodgepole Formation (particularly Lithostrotionella, Syringopora) exhibit a morphologic gradient from platy to hemispherical forms. The six morphologic categories of colonial corals discussed in this study are identified by mean …

Rodent Density And Species Composition In The Snake River Birds Of Prey Natural Area, Idaho, Jon R. Montan Jr.

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rodent densities were estimated in the major vegetation types of the Snake River Birds of Prey Natural Area in 1975 and 1976 by a combination of live-trapping and kill-trapping. Only deer mice (Peromyscus maniculatus) were numerous enough to permit reliable density estimates. Relative densities of other rodent species were indicated by kill-trap capture rates. Densities of deer mice correlated well (r = 0.99) with kill-trap capture rates. The use of kill-trapping in place of live-trapping in 1976 permitted extensive sampling throughout the 1930 km² study area. Differences were found among the major vegetation and land-use types in …

Seasonal Course Of Root Respiration In Atriplex Confertifolia, Richard S. Holthausen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Root respiratory response of mature Atriplex confertifolia plants growing in established communities was measured during two growing seasons using freshly excised root segments and gas chromatography techniques. Respiratory response at fixed test temperatures changed significantly during the growing season, and this pattern of respiratory adjustment varied for root segments located at different depths in the soil profile. Respiration measured at a constant test temperature was highest during early sumner, and declined to minimum values in late summer and fall. Root segments taken from the top 30 cm of the soil profile displayed peak activity several weeks before root segments from …

The Effect Of Four Mine Spoil Treatments On The Seedling Water Relations Of Two Plant Species, Lorraine K. Van Kekerix

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Surface mines in mountainous areas cause environmental deterioration at lower elevations in the watershed. The most successful long term solution to the downstream problem is revegetation. However, mine spoils are low in essential plant nutrients, have low water holding capacity, and are often acidic. These factors limit plant colonization. Plants must also be adapted to the environmental conditions of high elevations.

At the McLaren Mine, }1ontana, at 2800 m, it was observed that seedlings on revegetation plots were desiccated, indicating possible water deficits. Field and growth chamber studies were carried out to determine the effects of some spoil ameliorating treatments …

Blackbrush utilization levels averaged 30, 16, and 6 percent (545, 367, and 147 kg per hectare) for the heavily, moderately, and lightly browsed pastures, respectively; removal rates of 77, 38, and 19 percent (1164, 582, and 291 kg per hectare) were projected.

Statistically significant differences in body weight loss (P=0.052) were noted for goats browsing in different replications. Goats lost an average of 14 and 19 percent of body weight in replications one and two, …

Three Ordered Sets Of Factors And Their Relationship To Act Scores, Thomas J. Russo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There has been in recent years a marked decline in college entrance examination test scores. Declines have been documented both on the Scholastic Aptitude Test (SAT) and the American College Testing Program (ACT). In turn there has been an increasing interest concerning the test score declines as well as possible sources of influence on test scores. These sources or factors seem to be functions of three main "contexts." These contexts are: (a) school-related factors, (b) student-related factors and (c) family-structure related factors. It was of interest to attempt to explain the relative association of each variable to composite ACT scores …

Income Distribution Effects Of Water Quality Controls: An Econometric Approach, Ming Chien Chen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The imposition of water quality controls may affect the economy chiefly by altering aggregate production and changing the factor payments, These two effects could not only reallocate resources among production possibilities, but also could change the distribution of benefits of production among members of the society.

This study attempted to provide a workable theory to establish an empirical test of the impacts of water quality controls on family income distribution. It consists of two separate areas: first, to analyze methodologies of measuring income distribution changes, and, second, to develop a theoretical model that is useful for empirical tests of the …

The Evaluation Of A Computer Model To Predict The Effects Of Salinity On Crop Growth, James K. Wolf

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A model was developed to predict the effects of soil salinity on crop growth. The model makes three major assumptions: 1) Relative yield for a growing season is directly related to the ratio of actual and potential transpiration. 2) Water uptake by plants is in response to the water potential gradient between the plant roots and the surrounding soil. 3) The effects of the soil salinity on crop growth is solely due to the affect of osmotic potential in decreasing the water potential. Minor assumptions also included are concerned with the plant growth cover, plant root growth, and the separation …

Shoshoni Conceptualizations Of Plant Relationships, Bryan Ray Spykerman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Interviews were conducted with 10 Shoshoni-speaking people to investigate conceptualizations of plant relationships. A card-sort technique and informal questioning were employed in an attempt to elicit plant classifications and taxonomic relationships. Results indicate classifications are based on multiple criteria including morphology, cultural utilization, geographic setting and growth habit. A paradigm which postulates conceptualizations based on prototypic images fits the data better than the supposition that memory is composed of extensive taxonomic structures.

The Impacts Of Agriculture And Pastoralism On Wildlife In The Sudan, Fraser Tong Kuotwel

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

This report describes the effects of agriculture and pastoralism on wildlife resources in the Sudan. For centuries people in the western and southern Sudan have been earning their living through shifting cultivation and pastoralism. Being one of the agrarian countries of Africa, the Sudan is rapidly undergoing a transition from shifting cultivation to mechanized farming, in order to provide enough food for its rapidly growing human population, and to supply other Arab countries with the surplus. Mechanized farming and water associated development projects have great impact on wildlife resources, ranging from the destruction of wildlife habitat to the isolation of …

Effect Of Drilling Fluid Components And Mixtures On Plants And Soils, Parvin Pesaran (Djavan)

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The concern about the environment has required that the effects of drilling fluids (muds) on surrounding areas be known. This study was initiated to investigate the effects of various muds on plant growth and on soils.

In preliminary studies in Phase I (31 individual mud components), it was concluded that the obvious dominant effects on plant growth of detrimental drilling fluid components included excess soluble salts, excess exchangeable sodium percentage, possibly a high pH in some mixtures, and undesirable physical conditions. The latter resulted from the sodium and/or starch, gums, and bentonite.

Phase II, the second year's study of the …
