Forage Selection And Nutrition Of Sheep And Goats Grazing In The Tunisian Pre-Sahara, Rudolfo Ricardo Griego

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Nomadic pastoralism has been the traditional method of utilizing grazing resources in arid and semi-arid regions of Africa. However, increased sedentarization accompanied by growing human and animal populations during the past two decades is thought to be accelerating the desertification process, or desert expansion. The specific interactions of the grazing animal with this process has been speculated upon but not studied in detail. A comparative study was initiated during the spring grazing season of 1974 to determine sheep and goat nutritional and production responses, as well as patterns of vegetative selection and utilization under the pastoral system currently employed in …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The present study, conducted in 1974, was a longitudinal follow-up of two groups of female subjects who had participated in an earlier study (Wright and Johnson, 1960) while the subjects were university students. One group of the subjects had majored in fields considered at that time to be traditionally feminine majors, i.e. social sciences, art, music, education, homemaking, etc. The other group had majored in fields of exact sciences, which at the time were considered more traditionally masculine. The purpose of the present study was to determine whether differences noted in the 1960 study will exist between these two groups …

Noninformative Conditioned Reinforcers In Observing Response Training, Arnold Wellman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The goal of this research was to ascertain if information per se is a necessary condition to establish a conditioned reinforcer. Five pigeons were given observing response training in a two key Skinner box using free choice and forced trials procedures and a chain VI FI reinforcement schedule. The percentage of free choice noninformative trials was the observing response measure. A time correction procedure equated actual and programmed reinforcement frequencies in informative trials and noninformative trials if a difference occurred. For one bird a discrimination reversal of the informative and noninformative stimulus presentations occurred in the last five sessions.

The Identification Of Characteristics Of The Hyperactive Child Through Objective Evaluation, Joan Elaine Owen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

For many years adults have been concerned about the hyperactive child, who acts out in a boisterous manner, who is perhaps too physically stimulated and who is often perceived as not meeting adult expectations. It seems important to identify the characteristics of the hyperactive child in an objective and understandable manner so that parents, teachers, medical doctors, and mental health practitioners can determine more adequate prescriptive treatment programs.

The purpose of this study was to adjudge whether children referred for psychoeducational evaluation by pediatricians as hyperactive exhibit behavioral characteristics which, when evaluated by standardized tests, are significantly different from those …
