The Effects Of Elevation And Vegetation Type On Snow Accumulation And Melt In Logan Canyon, Utah, Paul R. Thies

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Snow accumulation and melt characteristics were studied in Logan Canyon, Utah. Three replications of aspen, conifer, and open field types at 6300, 7100,and 8000 feet were measured for snow depth and water content during 1972. Elevation was found to have the greatest effect on snow water content. The gradient of increasing water content with rise in elevation was found to be .51 inches/100 feet in the zone from 6300 to 7100 feet and 1.9 inches/100 feet from 7100 to 8000 feet. The cooler temperatures at higher elevations partially account for the 8000 foot zone beginning to melt 40 days after …

Some Economic Aspects Of Beef Crossbreeding In Utah, William L. Beaty

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to determine empirically if crossbreeding offers a more profitable alternative to Utah cattlemen than straightbreeding. Ranchers practicing breed crossing were interviewed to determine the relative merits of crossbreeding and straightbreeding in the categories of calf crop, weaning weight, sale price, and minor economic factors under ranch conditions. Crossbred and straightbred sale prices were analyzed utilizing the records of the Smithfield Livestock Auction.

Analysis of rancher interview data indicated that crossbred animals exceeded straightbreds in weaning weight and sale price. Crossbreds were further credited with lowering herd disease levels. No generalizations from comparative calf crop …

An Intensive Edaphological Characterization Of The Soils Of Malambito Experimental Station And Its Implications In Future Agricultural Research, William L. Rubink

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Malambito Experiment Station, in the Atlántico III project area, Department of Atlántico, Colombia, had almost no quantitative edaphological data on which to base agricultural research. Unexplainably low general yields as well as problem areas of deficient plant growth only confounded the results of field plot experiments. Intensive soil sampling and subsequent measurements of pH, EC_e of the saturation extract, and the four major cations disproved the previous suggestions that the crop growth problems were related to saline, sodic, or degraded soil conditions. The Ca/Mg+K+Na ratio, although significant when correlated with plant height, was sufficient explanation for only a small …

The Fixed-Interval Presentation Of A Small Fixed Ratio, Larry Allen Alferink

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In mixed fixed-ratio schedules, reinforcement is delivered according to two or more fixed-ratio components, which may be programmed in simple alternation or according to a random sequence. If the components simply alternate, the behavior is similar to that obtained in a multiple schedule. Pauses are long before long fixed ratios and short before short fixed ratios. If a random sequence is used, responding is characterized by short pauses after reinforcement independent of the size of the ratio and primes occur at the beginning of many of the fixed ratios. The purpose of the present study was to investigate the possibility …

Increasing Resistance To The Negative Effects Of Set, Paul B. Chance

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Two experimental studies were reported in which attempts were made to increase resistance to the negative effects of set. Set interference was measured by performance on 1) a task in which a set was experimentally induced, 2) a series of problems presumed to involve implicit sets, and 3) a test of creativity presumed to involve implicit sets.

The experimental treatments consisted of tasks which required set-breaking. An important aspect of this research was that no hints or instructions concerning sets were provided.

The findings offer modest support for the view that learning experiences can be designed which will increase resistance …
