Some Discriminative Functions of an Incidental Stimulus Adventitiously Associated with Reinforcement

Description: The present study was a systematic replication of a study by Morse and Skinner (1957). An attempt was also made to study some of the parameters involved in the sensory control of operant behavior. Morse and Skinner found that a stimulus present when a response is being reinforced may acquire discriminative control over the response even though its presence at reinforcement is adventitious.

Selected Dramas and Novelas of Juan Perez de Montalban

Description: The problem with which this investigation is concerned is that of analyzing and evaluating selected dramas and novelas of Juan Perez de Montalban.

Metric Half-Spaces

Description: This paper is a study of some of the basic properties of the metric half-space topology, a topology on a set which is derived from a metric on the set. In the first it is found that in a complete inner product space, the metric half-space topology is the same as one defined in terms of linear functionals on the space. In the second it is proven that in Rn the metric half-space topology is the same as the usual metric topology. In the third theorem it is shown that in a certain sense the nature of the metric halfspace topology generated by a norm on the space determines whether the norm is quadratic, that is to say, whether or not there exists an inner product on the space with the property that |x|^2=(x,x) for all x in the space.

Virial Theorem for a Molecule

Description: The usual virial theorem, relating kinetic and potential energy, is extended to a molecule by the use of the true wave function. The virial theorem is also obtained for a molecule from a trial wave function which is scaled separately for electronic and nuclear coordinates.

Spring Food Habits of Corydalus Cornutus L. in the Brazos River, Texas

Description: The objective of this study was to determine the kinds and numbers of food organisms consumed by Corydalus cornutus, and to investigate its periodicity of feeding during the spring months in the Brazos River, Palo Pinto County, Texas. A total of 468 larvae were collected at two-week intervals from February 29 to May 14, 1971. Larvae were taken at opportunity during three periods of the day, 6am.-12pm., 12pm.-6pm., and 6pm.-12am. A total of 23 different food items was observed in the 121 stomachs containing food. An expedient method of dissection of the digestive tract is included.

The Effect of Dietary Supplements of Protein and Wheat Germ Oil on Selected Physical Measurements of Junior High School Athletes

Description: This study was undertaken to determine the effect of protein and wheat germ oil supplements upon selected measures of junior high school boys. The measures selected were for weight, arm strength, speed and endurance, and urinalyses for urea nitrogen. Thirty-six ninth grade athletes at Memorial Junior High School in Alice, Texas, were used as subjects. The subjects were placed in three groups of twelve each with one group receiving the supplements and the other two groups serving as control groups.

An Ecological Study of the Pine Vole, Microtus Pinetorum, in Northeast Texas

Description: This study dealt with the life history and population dynamics of the pine vole, Microtus pinetorum. In the past there has been a void of ecological material concerning this small mammal in the southwestern region of its range. From November, 1969, through February, 1970, a survey was conducted in Marion County and Harrison County, Texas, to determine the most suitable habitat for an ecological study of Microtus pinetorum. A study was then initiated in March, 1970, and continued through March, 1971, on an undisturbed marsh five miles south of Marshall, Harrison County, Texas.

A Study of the Economic Development of the Navajo Indian Tribe 1930-1968

Description: This study is concerned with studying and analyzing the development work thus far carried out on the Navajo economy. It is assumed that these efforts have been instrumental in bringing the Navajo economy from that of a subsistence agricultural economy to one that is beginning to enter our modern world. The study deals primarily with the economic development of the Navajo tribe from 1930 until the present time.

On Lane's Integral

Description: The problem and purpose of this paper is to develop Lane's Integral in two-space, and then to expand these concepts into three-space and n-space. Lane's Integral can be used by both mathematicians and statisticians as one of the tools in the calculation of certain probabilities and expectations. The method of presentation is straightforward with the basic concepts of integration theory and Stieltjes Integral assumed.
