Hard Work Beats Talent, Unless Talent Works Hard: Exploring The Relationship Between Self-Efficacy And Sales Performance, Mohammad Sakif Amin

Graduate Theses, Dissertations, and Problem Reports (ETD)

Current research in sales suggests that salesperson self-efficacy, which is a person’s belief about his/her ability to achieve a desired level of performance in a given task, affects sales performance positively. The logic behind this positive effect is that people who exhibit a high level of self-efficacy have increased motivation and thus exert increased efforts towards completing a task. Research in psychology, however, suggests that there can be a downside to self-efficacy. Drawing on perceptual control and ego depletion theories, this dissertation explores two possible dark side effects of self-efficacy in a sales context: (1) decreased salesperson effort engendered by …

Family Forest Owners Satisfaction With Timber Transactions, Jeffrey M. Lee

Graduate Theses, Dissertations, and Problem Reports (ETD)

Forest industries in the eastern U.S. rely heavily on family forest owners to supply fiber needs for their mills. As of 2017, 79 percent of West Virginia is classified as forestland and of this roughly 86.5 percent is privately owned. With such a heavy reliance on wood from private forest lands, family forest owner satisfaction is extremely important if companies want to continue harvesting or working with these landowners in the future.

Timber transactions are complex. No two timber transactions are exactly the same. They often involve many different parties apart from the landowner. Site conditions, land cover, and landowner …

Graduate Theses, Dissertations, and Problem Reports (ETD)

Methane (CH4) explosions pose significant dangers in longwall mining that may lead to injuries and fatalities. Safety is improved through diligent monitoring of CH4 concentration. Currently, regulations require a CH4 monitor be placed on the shearer, downwind of the cutting head. Portable monitor measurements must be taken at various times and locations. If any CH4 monitor measures a concentration greater than 1%, a warning signal must be given. Based on previous research and the location of the CH4 monitor mounted on the shearer (closest monitor to the face), if 1% methane is measured, the concentration at the face may be …

Environmental Contaminants, Parasitism, And Neoplasia In White Perch Morone Americana From Chesapeake Bay, Usa, Mark Arnold Matsche

Graduate Theses, Dissertations, and Problem Reports (ETD)

White perch are an abundant demersal fish species in freshwater and oligohaline habitats of the Chesapeake Bay. An avoidance of salinity > 12-15 ppt generally restricts the distribution and movements of fish to within tributaries in the mid to lower Bay, which over time has resulted in the formation of at least three separate stocks in Chesapeake Bay. Sub-populations of white perch that are partially isolated may serve as sentinels of the conditions or stressors in the tributaries in which they reside. Fish are exposed to a variety of environmental contaminants and other anthropogenic stressors that can vary in magnitude based …

Frontal Brain Injury: Effects On Flexibility, Impulse Control, And Attention, Christopher Matthew O'Hearn

Graduate Theses, Dissertations, and Problem Reports (ETD)

Traumatic Brain Injury (TBI) is defined as an impact to the head, penetration of the skull, or rapid deceleration of the skull, resulting in an alteration of brain function or neurological deficit. Cognitive deficits are common following TBI and often go unresolved due to a lack of effective treatments. These deficits often perseverate into the chronic post injury phase, so the development of rehabilitative strategies is imperative. Behavioral flexibility, impulse control, and attention are a few cognitive processes that are commonly affected by TBI. The current research compares these processes between rats with and without a severe frontal brain injury …

Struggle For Sovereignty: An African-American Colonization Attempt And Delicate Independence In Mid-Nineteenth Century Central America, Matthew D. Harris

Graduate Theses, Dissertations, and Problem Reports (ETD)

This thesis uses a series of United States foreign relations documents centered around an 1862 attempt by Abraham Lincoln to colonize parts of Central America with freed African Americans. Traditionally, these communications have been used by historians for U.S. foreign relations or Black resettlement history. Here, instead, this collection is used to display the major threats to Central American sovereignty in the mid-nineteenth century in their own words. The collection reveals that two of the threats were foreign imperialistic thought and racial instability. However, the third, and ultimately most destabilizing threat to the region, was the five nations' rivalry amongst …
