From these results Humboldt published three major works about the expedition, particularly a thirty-volume work condensed to two volumes, Vues de Cordilleres et monuments des peuples d' Amerique.;From this …


Limits Of Sensitivity To Delayed Timeout From Avoidance, Chad Michael Galuska Dec 2000

Limits Of Sensitivity To Delayed Timeout From Avoidance, Chad Michael Galuska

Graduate Theses, Dissertations, and Problem Reports

Session-reduction procedures have been employed to assess molar control of avoidance responding. By conceptualizing session reduction as a delayed timeout from avoidance, the present study investigated the limits of molar control while minimizing several methodological limitations inherent in such procedures. Six times during each session, a two-link chain schedule was superimposed on a baseline schedule of variable-cycle shock avoidance. Completion of the initial link (fixed-ratio 10 schedule) produced a timeout following a signaled delay during which the avoidance schedule remained operative. For most rats, the delay was manipulated across conditions from 0 s to 60 s. Control by the delayed …

Increasing Nutrition Knowledge And Food-Related Behavior Practices Among Participants In The "Dining With Diabetes" Program In West Virginia, Amy B. O'Dell Dec 2000

Increasing Nutrition Knowledge And Food-Related Behavior Practices Among Participants In The "Dining With Diabetes" Program In West Virginia, Amy B. O'Dell

Graduate Theses, Dissertations, and Problem Reports

Diabetes is a serious disease that effects a large number of West Virginia's population. A study was conducted using 591 diabetic and non-diabetic subjects who attended the "Dining with Diabetes" program. Subjects completed a demographic form, pretest, and posttest. Pearson's correlation and ANOVA were used to determine the effect of a diabetes intervention program on nutrition knowledge, diabetes behaviors, and practices. The results indicated that there was no significant difference in nutrition knowledge between diabetic and non-diabetic subjects. Interaction was noted when subjects were placed into groups based on their pretest score (p < 0.07). The change in score (posttest score-pretest score) was negatively correlated with pretest score (r = -0.75, p < 0.00). Significant association was also noted between nutrition knowledge score and several behavior and diabetic practices. The results conclude that diabetes education programs may significantly affect some behaviors and diabetic practices.
