Integrin Mediated Mechanotransduction In Renal Vascular Smooth Muscle Cells, Lavanya Balasubramanian

USF Tampa Graduate Theses and Dissertations

Integrins are transmembrane heterodimeric proteins that link extracellular matrix (ECM) to cytoskeleton and have been shown to function as mechanotransducers in non-muscle cells. Synthetic integrin-binding peptide triggers Ca²⁺ mobilization and contraction in vascular smooth muscle cells (VSMCs) from rat afferent arteriole, indicating that interactions between ECM and integrins modulate vascular tone. RGD, an integrin binding peptide, triggered contraction in cultured VSMCs as observed by Electric Cell-Substrate Impedance Sensing technique. To examine whether integrins transduce extracellular mechanical stress into intracellular Ca²⁺ signaling events in VSMCs, unidirectional mechanical force was applied to freshly isolated renal VSMCs through paramagnetic beads coated …

A Comparative Study Of Healthcare Procurement Models, Arka Bhattacharya

USF Tampa Graduate Theses and Dissertations

Group Purchasing Organizations (GPOs) play a significant role in the healthcare industry. The presence of GPOs helps the healthcare centers to offload their responsibilities so that they can focus on more critical areas which require attention like providing quality care.

This thesis involves the comparison of three models of procurement operations in terms of cost efficiency. This cost comparison model features a healthcare organization associated with a national GPO, a healthcare organization which procures by self sourcing (not associated with a GPO), and a hybrid procurement model involving a national GPO and a regional GPO. The comparison model highlighted the …

Utilization Of Community-Based Transitional Housing By Homeless Veteran Populations Diagnosed With A Mental Illness: The Association Between Predisposing, Enabling, And Need Factors With Program Outcomes, Roger Casey

USF Tampa Graduate Theses and Dissertations

Mental illness among homeless populations is a significant public health issue. Community-based programs that assist the homeless are most often developed to meet local housing needs, not the needs of mental health populations. Transitional housing, a model frequently utilized to address homelessness in communities, provides program-based housing with supportive services.

The purpose of this study was to examine the associations between participant- and program-level factors on the utilization of community-based transitional housing by homeless veterans diagnosed with a mental illness. The study tested a revised framework of the behavioral model of utilization for vulnerable populations theory.

The sample was comprised …

Acoustic Classification Of Benthic Habitats In Tampa Bay, Shane C. Dunn

USF Tampa Graduate Theses and Dissertations

The need for assessment of benthic habitat characteristics may arise for many reasons. Such reasons may include but are not limited to, habitat mapping, environmental concerns and identification of submerged aquatic vegetation. Oftentimes, such endeavors employ the use of aerial photography, satellite imagery, diving transects and extensive sampling. Aerial photography and remote sensing techniques can be severely limited by water clarity and depth, whereas diver transects and extensive sampling can be time consuming and limited in spatial extent. Acoustic methods of seabed mapping, such as the acoustic sediment classification system QTC are not hampered by water clarity issues. The acoustic …

First-Principles Studies Of Energetic Materials, Michael W. Conroy

USF Tampa Graduate Theses and Dissertations

First-principles density functional theory calculations were performed on a number of important energetic molecular crystals, pentaerythritol tetranitrate (PETN), cyclotetramethylene tetranitramine (HMX), cyclotrimethylene trinitramine (RDX), and nitromethane. Simulations of hydrostatic and uniaxial compressions, as well as predictions of ground-state structures at ambient conditions, were performed using the DFT codes CASTEP and VASP.

The first calculations done with CASTEP using GGA-PW yielded reasonable agreement with experiment for the calculated isothermal EOS for PETN-I from hydrostatic compression data, yet the EOS for β -HMX shows substantial deviation from experiment. Interesting anisotropic behavior of the shear-stress maxima were exhibited by both crystals upon uniaxial …

The purpose of this study is to evaluate the causal effects of malaria and poor health in general on economic outcome in Sub-Saharan Africa. This study uses panel data from the Living Standard Measurement Survey (LSMS) for Tanzania from 1991 to 2004. Three main hypotheses are tested. First, the study evaluates the effect of malaria and other chronic illnesses on labor supply using the number of hours worked per week as a measure of outcome. Second, it determines the impact of poor health on human capital accumulation by measuring the number of weekly school hours lost to illness. The third …

Reading Fluency Through Alternative Text: Rereading With An Interactive Sing-To-Read Program Embedded Within A Middle School Music Classroom, Marie Biggs

USF Tampa Graduate Theses and Dissertations

Singing exaggerates the language of reading. The students find their voices in the rhythm and bounce of language by using music as an alternative text. A concurrent mixed methods study was conducted to investigate the use of an interactive sing-to-read program Tune Into Reading (Electronic Learning Products, 2006) as an alternative text, embedded within a heterogeneous music classroom. Measured by the Qualitative Reading Inventory-4 (QRI-4) (Leslie & Caldwell, 2006), the fluency, word recognition, comprehension, and instructional reading level of the treatment students were compared to their counterparts who sang as part of the regular music program. Concurrently, this investigation also …

Development Of Micro/Nanosensor Elements And Packaging Techniques For Oceanography, Shyam Aravamudhan

USF Tampa Graduate Theses and Dissertations

In this research, novel high resolution reinforced diaphragm MEMS piezoresistive pressure sensors were designed, fabricated and tested to measure physical phenomena (such as depth/pressure variations) in the ocean. To complement the physical sensing elements, a microfluidic electrochemical nitrate sensor, was also developed to detect chemical fluxes. The electrochemical sensor was designed and packaged to conform to a flow through system. The multisensor approach will enable better measurement quality compared to the current ocean sensors. This, in turn, will potentially improve the current understanding of physical and biogeochemical processes from coastal to deep-sea environment.

The pressure sensor element utilized a reinforced …

Since the successful implementation of biosensors requires a good understanding and versatile control of the semiconductor surface …

The Effects Of Mentoring On The Elementary Special Education Mentor, Maria Angeliadis

USF Tampa Graduate Theses and Dissertations

Increasingly, mentor programs are being developed in teacher education programs to assist novice teachers. The focus in most of the literature on mentoring is on the new teacher being mentored. While the mentor teacher appears to be the most crucial element in mentoring programs (Feinman-Nemser, 1992; Little, 1990; White, 1995), there is not much information about how a teacher experiences being a mentor or the perceived benefits to a mentor.

The purpose of this present study was to examine the effects of mentoring on mentors in order to: (a) address the gap in the literature by exploring the effects of …

Examining The Myth Of Narcissus And Its Role In Moby-Dick, Gerald E. Hansen

Student Works

In Moby-Dick's famous opening line, "Call me Ishmael," Melville establishes the creation of identity as one of the core purposes of the narrator and central themes of the subsequent narrative. The narrator does not say whether Ishmael is his real name only that this and the accompanying connotations are the identity by which he wants to be known and perhaps through which he sees himself. In these first three words, Ishmael immediately suggests that he wants to shape and control how he is perceived by himself and others.

Evaluation Of The Supply Chain Of Key Industrial Sectors And Its Impact On The Electricity Demand For A Regional Distribution Company, Thiago Arruda Mariotoni

USF Tampa Graduate Theses and Dissertations

Considering the international scenario, in a recent past, the electrical industry was based on the concepts of monopolistic concessions and vertical utilities structures. In Brazil, until recently, the electricity companies were all governmental properties that served restricted monopolized areas. In a similar manner, in the United States, monopolies for certain concession areas were assigned to vertically integrated electric utilities. This monopolistic portfolio brought to the industry, in a generic sense, a lack in the interface between companies and consumers. This fact established a low capacity of obtaining consumer's information and consequently, a low capacity of developing precise demand forecasts.

Lately, …

Risk Reduction Decision Making In Women With Brca1/2 Gene Mutations, Heidi M. King

USF Tampa Graduate Theses and Dissertations

With technological advances in testing for gene mutations, a new population of BRCA1/2 women is becoming aware of their increased risk for developing breast and/or ovarian cancer. A salient issue these women face is which risk-reducing option to choose. Little is known about the decision making factors underlying the choice of prophylactic mastectomy for women with a BRCA1/2 mutation. To address this issue, 137 unaffected, positive BRCA1/2 gene mutation carriers (42 who opted for prophylactic mastectomy, 95 who did not) served as participants. All women completed an on-line battery that assessed the following theory-based decision making variables: advantages and disadvantages …

Non-Invasive Manipulation Of Membrane Potential In Intact Living Cells, Robin Dando

USF Tampa Graduate Theses and Dissertations

All living cells contain the electrogenic enzyme Na/K ATPase, whose function is to pump ions against the electrochemical gradient, in order to provide potential energy which is later used for cellular processes such as action potentials, muscle contraction and facilitated transport. Using a technique developed in our lab, exploiting the molecule's voltage dependence, it is possible to increase this pump function by many folds. Optical measurement of the membrane potential of living cells was made using a potentiommetric dye, with successful manipulation of the ionic concentration and membrane potential reported. Additional supporting results are presented, along with extension of this …

Interagency Collaboration And Communication: Funders And Service Providers Working Together To Create A Management Service Organization, Beth E. Eschenfelder

USF Tampa Graduate Theses and Dissertations

Charitable nonprofit organizations are growing in number and scope, but the body of literature and knowledge about communication within these organizations is limited. Today, charitable organizations face a flurry of economic and environmental factors that challenge their continued survival: growing community needs, mounting funding cuts from all segments of government, increased competition for funding, a limited pool of dedicated community leaders to serve on boards, decreased charitable giving for some causes, and persistent calls for greater accountability. As nonprofits explore new ways of coping with these socioeconomic pressures---such as reorganization, consolidation, mergers, and management service organizations---there is a clear need …

Uniting Octave And Sestet: Completing 'The Cycle' Of Mckay's Sequence, Cocoa Williams

All Theses

This thesis examines Claude McKay's The Cycle (c. 1943) in relationship to how McKay's other sonnets have been received by scholars and the ways in which this collection speaks to fallacies concerning didactic art, African American views on the British literary tradition, and the literary merit of McKay's later poetry post Catholic conversion. Much of the criticism on McKay's other sonnets deals primary with the question of whether the sonnet form is an appropriate vehicle for such mutinous and didactic commentary. Critics tend to answer this question in one of two ways. Some assert that because the relationship between form …
