This study investigated self-efficacy beliefs related to online instruction. Self-efficacy, a psychological construct, is defined as self-appraisal of one's capabilities to plan and undertake a course of actions required for a specified task.

The objectives of this study were to (a) develop a survey instrument to measure the psychological construct of self-efficacy related to online instruction; (b) identify the salient factors of …

Effects Of Dietary Fatty Acids On Intestinal Tumorigenesis In ApcMin/+ Mice, Melissa Hansen Petrik

Doctoral Dissertations

Dietary fat is thought to be an important environmental factor influencing colorectal cancer risk. n-3 polyunsaturated fatty acids (PUFA) have been linked to a lower risk of colorectal cancer and it has been presumed that this effect is due to their ability to interfere with synthesis of 2-series prostaglandins from arachidonic acid (AA, 20:4 n-6). However, the specific mechanism has not been clearly established. Therefore, we hypothesized that select dietary fatty acids would modulate intestinal tumorigenesis through interference with AA metabolism in the Apc^Min/+ mouse, a unique model system bearing many similarities to human intestinal cancer. α-linolenic acid (ALA, …
