The Relevance Of Offsetting Policy Effects: Covert Distributive Politics In The Conservation Reserve Program , Robert Carey May 2007

The Relevance Of Offsetting Policy Effects: Covert Distributive Politics In The Conservation Reserve Program , Robert Carey

All Dissertations

The Conservation Reserve Program (CRP), as initially authorized by the Food Security Act of 1985, operated by removing land from agricultural production in order to generate environmental benefits, primarily erosion reduction. Policy, however, often generates unintended consequences. One potential unintended consequence in the CRP is slippage; if the upward pressure that the idling of cropland exerts on commodity prices results in the activation of new land, behavior that may partly offset the program's environmental benefits, then price-feedback slippage is said to have occurred. Examination of county-level wheat production data for the United States during the years 1980 to 1993 utilizes …

The Impact Of A Physical Activity Intervention On The Physical Activity Self-Efficacy Of Preadolescent Females, Katherine Hommel May 2007

The Impact Of A Physical Activity Intervention On The Physical Activity Self-Efficacy Of Preadolescent Females, Katherine Hommel

All Theses

Females often do not participate in the recommended level of physical activity on a regular basis possibly leading to both physical and psychological consequences. Reasons for lack of participation include a lack of self-efficacy. Self-efficacy theory proposes that self-efficacy is a key determinant in maintenance, adoption, and perseverance in difficult tasks. Recent literature has supported a relationship between an individual's physical activity self-efficacy and actual behaviors relating to physical activity.
The Finding Your Voice program was aimed at increasing pre-adolescent female's self-efficacy for physical activity through education and practical experience. The primary purpose of this study was to determine the …
