Eutrophication Trend Of Lakes In The Tampa Bay Watershed And The Role Of Submerged Aquatic Vegetation In Buffering Lake Water Phosphorus Concentration, Max Jacobo Moreno Madriñan

USF Tampa Graduate Theses and Dissertations

Twentieth century human settlement within the Tampa Bay watershed was linked to a dramatic mid-century decline in bay water quality and loss of seagrass acreage. Decades of direct and indirect nutrient discharges to the bay from phosphorus mining, fertilizer manufacturing, and wastewater treatment, as examples, impaired the estuary. In the past twenty years, regional stakeholders have worked to improve the bay water quality by reducing point and non-point source nutrient loading to the bay.

Lakes within the Tampa Bay watershed may play an important role in attenuating the flow of nutrients into the bay. This study hypothesized that between 1990 …

The Competencies For Community College Leaders: Community College Presidents' And Trustee Board Chairpersons' Perspectives, Anthony M. Hassan

USF Tampa Graduate Theses and Dissertations

At a time when strong leadership is needed to guide community colleges forward, a major crisis seems to be stirring (Eddy & VanDerLinden, 2006). According to some estimates, 45% of community college presidents will have retired by 2007 (Shults, 2001) and an even worse prediction offered by Weisman and Vaughan (2002) predict 79% of community college presidents will be retired by 2012. Echoing this view, Amey et al. (2002) assert that there is much work to be done in preparing the younger generations of community college leaders with skills and competencies necessary to meet this leadership challenge.

There were two …

Creative City And Fields Of Cultural Production: Ethnographic Perspectives Of “The Arts” In Tampa, James Kuzin

USF Tampa Graduate Theses and Dissertations

Stimulated by the economic theories of Richard Florida (2005), the City of Tampa established the Office of Creative Industries (OCI) to oversee efforts to strengthen the presence and visibility of "the arts." This thesis presents ethnographic research focused on practices, and perspectives among members of the OCI's service population. From July 2006 to July 2007, I conducted fieldwork among a diverse group of stakeholders possessing a unique connection to the aims of the OCI. The central problem addressed in this research looks at the degree to which cultural change occurs from participatory, grass-roots initiatives, rather than ones emanating from "the …

Functional Remodeling Of The Cardiac Glycome Throughout The Developing Myocardium, Marty L. Montpetit

USF Tampa Graduate Theses and Dissertations

Cell surfaces are replete with complex, biologically important glycans responsible for multiple cellular functions including cell adhesion and cellular communication. Proper protein glycosylation is essential for normal development and often pathologies are marked by altered glycosylation. Here, data showed that the auxillary subunit, ß₁, modified voltage-gated Na⁺ channel (Na_v) gating in an isoform-specific, sialic acid dependent, and saturating manner. The regulated activity of the hundreds of glycogenes (glycosylation-associated genes) is responsible for protein glycosylation; this could result in a glycome of thousands of glycan structures. Microarray analyses indicated that glycogene expression was highly regulated throughout …
