Intangible Capital: Culture Of Innovation And Its Impact On The Cash Flow Multiple, James Russell Gregory

USF Tampa Graduate Theses and Dissertations

The definition for a culture of innovation (COI) is the perception of a company that prioritizes the advancement of new ideas that create value across all operations. On the face of it that seems a precious attribute for any company to nurture and exploit, but measuring and valuing a culture of innovation has proven elusive for corporations. There is a tendency to break down innovation into R&D, patents granted, and new product development and while these are all significant components of innovation a cultural definition is more encompassing of the entirety of a company and the financial results should be …

Decreased Visibility: A Narrative Analysis Of Episodic Disability And Contested Illness, Melissa Jane Welch

USF Tampa Graduate Theses and Dissertations

In the United States alone, disability touches the lives of a tremendous amount of people. An increased prevalence of chronic illness, coupled with an aging population means it is likely and perhaps inevitable that everyone will experience disability in one way or another over the course of their lifetime. However not everyone who is disabled is recognized as such. Culturally, the narrative of “the healthy disabled person,” – or someone who is healthy, permanently, predictably, and visibly disabled renders many people with chronic and episodic pain, fatigue, and illness as unrecognizable as disabled. Even though increasing numbers of disability scholars …

An Effectual Approach For The Development Of Novel Applications On Digital Platforms, Onkar Shamrao Malgonde

Race And Gender In (Re)Integration Of Victim-Survivors Of Csec In A Community Advocacy Context, Joshlyn Lawhorn

USF Tampa Graduate Theses and Dissertations

In this thesis, I use feminist ethnography at a nonprofit organization to analyze the racialized gender in (re)integration of victim-survivors of commercial sexual exploitation of children (CSEC). Critical race feminism and intersectionality are the theoretical frameworks to guide the analysis of community advocacy. The analysis considers two themes with various subsections that capture CSEC at the site. The first theme analyzes the definition, challenges, coordination and rhetoric of reintegration at the site. The second theme highlights the site’s racial identity, Black victimhood of victim-survivors of CSEC in the context of community, and racialized gender within reintegration. I discuss the strategic …

Impact Of Recirculating Nitrified Effluent On The Performance Of Passive Onsite Hybrid Adsorption And Biological Treatment Systems, Amulya Miriyala

USF Tampa Graduate Theses and Dissertations

Approximately 25% of households in the U.S. treat their wastewater onsite using conventional onsite wastewater treatment systems (OWTS). These systems typically include a septic tank or a series of septic tanks followed by a soil absorption system. They effectively remove biochemical oxygen demand (BOD), total suspended solids (TSS), fats and grease but are not designed to remove significant amounts of nitrogen. High nitrogen loading to coastal and ground waters can be dangerous to aquatic life and public health. Hence, there is a need for advanced onsite wastewater treatment systems that can effectively remove nitrogen. Making enhanced nitrogen removal for OWTS …

Quantitative Measurement Of Cerebral Hemodynamics During Activation Of Auditory Cortex With Single- And Multi-Distance Near Infrared Spectroscopy, Penaz Parveen Sultana Mohammad

USF Tampa Graduate Theses and Dissertations

Functional Near Infrared Spectroscopy (fNIRS) is a safe, low-cost, non-invasive opti-cal technique to monitor focal changes in brain activity using neurovascular coupling and measurements of local tissue oxygenation, i.e., changes in concentrations of oxygenated hemoglobin (HbO) and deoxygenated hemoglobin (HbR)[42]. This thesis utilizes two fNIRS approaches to measure hemodynamic changes associated with functional stimulation of the human auditory cortex. The first approach, single-distance continuous wave NIRS (CW-NIRS) utilizes relatively simple instrumentation and the Modified-Beer Lambert (MBL) law to estimate activation induced changes in tissue oxygenation (∆CHbO and ∆CHbR)[17]. The second more complex approach, frequency domain NIRS (FD-NIRS), employs a photon …

Raptors And Humans: Exploring Alternative Therapies In Non-Clinical Environments Using Birds Of Prey, Kaleigh Hoyt

USF Tampa Graduate Theses and Dissertations

This study aims to deconstruct current conceptions about animal-assisted interventions by investigating relationships between human beings and birds of prey. Interactions between birds of prey, or “raptors,” provide novel cases from which to reexamine failed attempts to provide empirical data in support of alternative therapies. Previous research addressing the efficacy of animal-assisted interventions is simply not robust enough to be considered a feasible treatment option by medical professionals. By extension, models of self-regulation in psychology are often presented using reductionist models and oversimplified therapeutic outcomes. Taken together, raptor-human relationships help to highlight the shortcomings of each, as well as potential …

Expediting The Consolidation Of Clayey Soils Utilizing Microwaves, Thilini Jayatissa

USF Tampa Graduate Theses and Dissertations

Post-construction settlement has been an issue in the field of construction due to the excessive time taken for the dissipation of pore water pressure.
