Leadership Frames In Comprehensive Community Colleges: Implications For The Market-Responsive College, David Layne Campbell Dec 2017

Leadership Frames In Comprehensive Community Colleges: Implications For The Market-Responsive College, David Layne Campbell

Theses and Dissertations

Market-responsive college leaders are challenged to navigate external relationships with business and industry, government officials, and community leaders, as well as the resulting pressures of multiple missions of the comprehensive community college. The leaders are faced with three predominant issues involving the market-responsive college and its relationship to the overall comprehensive college. These issues include: (a) its relationship to the transfer role, (b) difficulty of defining and measuring its success, and (c) its placement within the organization. Bolman and Deal’s (2013) leadership frames provide a model to understand how framing by market-responsive college leaders influences their organizations. A qualitative case …

Effects Of Preemergence Herbicides On Hybrid Bermudagrass Root Growth, Establishment, And Sod Harvestability, Erick G. Begitschke

Theses and Dissertations

Preemergence herbicides are generally considered as a group to negatively affect hybrid bermudagrass (Cynodon dactylon (L.) Pers. × C. transvaalensis Burtt-Davy) establishment. However, little is known about the effects upon hybrid bermudagrass root growth, establishment, and sod harvestability. Several research projects were conducted at Mississippi State University to determine the effects of commonly used preemergence herbicides on hybrid bermudagrass sod production. Measured response variables included visually estimated hybrid bermudagrass cover, normalized difference vegetative index (NDVI), ratio vegetative index (RVI), relative chlorophyll concentration (CI-RE), sod tensile strength, root mass, root length, root surface area, average root diameter, and root carbohydrate concentration …

Using Deuterium And Oxygen-18 Stable Isotopes To Understand Mechanisms Of Stemflow Generation As A Function Of Tree Species And Climate, Mercedes Siegle-Gaither Dec 2017

Using Deuterium And Oxygen-18 Stable Isotopes To Understand Mechanisms Of Stemflow Generation As A Function Of Tree Species And Climate, Mercedes Siegle-Gaither

Theses and Dissertations

Stemflow creates biogeochemical hotspots at tree bases. Few studies examine bark structure effects on stemflow generation via stable isotopes. Stemflow volume and isotopic composition (δD, δ18O) were measured over 15 months to address three main objectives: to determine origins and pathways of stemflow, to identify differences in stemflow generation mechanisms between tree species, and to identify differences in stemflow generation mechanisms between meteorological events. Laser ablation spectroscopy showed that, compared to throughfall and precipitation, stemflow was isotopically enriched, signifying isotopic fractionation. A bark-wetting experiment showed bark water storage capacity to be greatest in species with thick, continuous bark. Isotopic composition …

Authentic Leadership, Research Integrity, And Institutions Of Higher Learning: Why Focusing On Departmental Leadership Is Critical For Preserving The Sanctity Of Science, Katherine I. Echols Dec 2017

Authentic Leadership, Research Integrity, And Institutions Of Higher Learning: Why Focusing On Departmental Leadership Is Critical For Preserving The Sanctity Of Science, Katherine I. Echols

Theses and Dissertations

One of the most overlooked and complex problems that universities and colleges face nation-wide is how to reduce and eliminate research misconduct. Because of the confidential nature of allegations of research misconduct and the high rate of underreporting, administrators at scholarly institutions struggle with understanding the cause of such behavior. Without a clear picture of the prevalence of misconduct or the barriers to reporting, leaders at institutions of higher learning find themselves at a disadvantage when dealing with these problems. This uncertainty coupled with a growing regulatory emphasis from federal funding agencies, results in a reactionary approach while questionable practices …

The Effects Of Cover Crops And Tillage Method On Sweetpotato [Ipomoea Batatas (L.) Lam.] In North Mississippi., Jeffrey Len Main

Theses and Dissertations

Sweetpotato (Ipomoea batatas (L.) Lam) is a major food resource of much of the world. Sweetpotato production is damaging to the soils in which it is grown due to the nature of production and the condition the soil is left to overwinter. There is potential for future regulation on the production of sweetpotato as related to runoff and nonpoint source pollution as the sediment from runoff erosion is easy to pinpoint in nearby waterways. Two studies were carried out to determine the effect of a reduced tillage practice and cover crops on the accumulation of nutrients in cover crops and …

Epidemiology Of Enterohemorrhagic Escherichia Coli: Detection And Ecology In Beef Cattle Systems, Liesel J. Schneider

Theses and Dissertations

Enterohemorrhagic Escherichia coli (EHEC) are important foodborne pathogens with a bovine reservoir. For many years, research and regulations have focused on the EHEC serogroup most commonly associated with severe human illness, EHEC O157. However, six additional EHEC serogroups have been identified as important human foodborne pathogens and have been declared adulterants in raw, non-intact ground beef by the United States Department of Agriculture’s Food Safety Inspection Service. Collectively these seven organisms are referred to as EHEC-7. With the addition of these six pathogens, epidemiological studies are needed to estimate the probability for cattle to carry them and to identify risk …

"A Grave Subject:" Hollywood Cemetery And The Ideology Of Death In Mid-Nineteenth Century America, Kelli Brooke Nelson Dec 2017

"A Grave Subject:" Hollywood Cemetery And The Ideology Of Death In Mid-Nineteenth Century America, Kelli Brooke Nelson

Theses and Dissertations

During the nineteenth century, Americans began to develop a new relationship with death. Urbanites were less confronted with the constant presence of the dead and dying than they had in the past. A new trend in cemeteries also developed as a result. The Rural Cemetery Movement promoted the idea that the dead should be buried amongst a natural setting that was pleasing and calming to visitors. The first few initial cemeteries were an immediate success, but this was not the case in Richmond, Virginia. Although the developers had grand ideas about their cemetery project, Richmonders opposed the cemetery in the …
