Preliminary Investigations In The Effect Of Continually Changing Reinforcement On Learning And Extinction, Michael Dinoff

Masters Theses

A great deal of research has been done in the gener­al area of manipulating reinforcement parameters. However, reinforcement per se has rarely been varied systematically from trial to trial. The research exceptions have been indicated. In these experiments , the nutritive value, the delay, or the units of reinforcement have been systematical­ly varied and the results are not always conclusive as re­gards the experimental variable itself. The present study attempts to control for these factors and yet vary systema­tically properties of the reinforcing agent alone. Pigeons were the experimental subjects and they worked for food while they were at a …

Beliefs And Attitudes Of Recent High School Graduates On The Subject Of Beverage Alcohol, Francis E. Chape

Masters Theses

Introduction

During recent years, many investigations concerning the teen-ager and beverage alcohol have been carried out. A survey of the available literature on this subject revealed that most of the studies have been made to determine the attitudes toward drinking and the drinking behavior of this age group. These studies, Maddox¹ states, provide "The basis for generalizations about drinking in high school which are more substantial than impressionistic guesses."

Generalizations, however, have not been limited to drinking behavior alone. Alcohol education programs, required by law in every state in the union,² have received much criticism in recent times. …

The Uptake Of Sodium Ions By The Tongue, Magill Echols

Masters Theses

We have seen a wealth of data demonstrating that salt prefer­ ence thresholds decrease as salt deprivation continues. Careful studies indicate that these fluctuations cannot be accounted for in terms of changes in neural excitatory thresholds. It is reasonable to assume that something on or about the tongue may change with sodium deprivation. The problem approached in this study was the search for evidence of such a change.

The experimental hypothesis was, "that sodium ions actually penetrate the surface of the tongue according to the sodium depriva­ tion experienced by the animal."

This was basically a search for processes associated …

Water Resources Development -- An Analysis Of Economic Justification Practices Of The Corps Of Engineers, Kerwood W. Barrand

Masters Theses

"Presented herein is a brief analysis of the economic justification practices of the Corps of Engineers as commonly implemented in proposals concerning water resources projects. Where applicable, recommended methods are compared to similar methods advocated for, and accepted by, private engineering firms in similar situations.

The major problem exists in the lack of a profit motive in programs undertaken with the use of public funds. However, a profit can be said to have been realized in public works programs if the total benefits of the programs to all the people exceed the costs of these programs and, further, if the …
