An Integrated Building Water Management Model For Green Building, Caryssa Joustra

USF Tampa Graduate Theses and Dissertations

The U.S. Green Building Council (USGBC) is the developer of the Leadership in Energy and Environmental Design (LEED™) green building scoring system. On first inspection of LEED points, few address water efficiency. However, water management encompasses other points beyond the Water Efficiency (WE) category. In general, the industry is apt to take a somewhat compartmentalized approach to water management. The use of alternative water sources or the reuse of wastewater significantly complicates the water budget picture. A total water management systems approach, taking into consideration water from various sources, both inside and outside the building, should be implemented in order …

Detecting Group Turns Of Speaker Groups In Meeting Room Conversations Using Audio-Video Change Scale-Space, Ravikiran Krishnan

USF Tampa Graduate Theses and Dissertations

Automatic analysis of conversations is important for extracting high-level descriptions of meetings. In this work, as an alternative to linguistic approaches, we develop a novel, purely bottom-up representation, constructed from both audio and video signals that help us characterize and build a rich description of the content at multiple temporal scales. Nonverbal communication plays an important role in describing information about the communication and the nature of the conversation. We consider simple audio and video features to extract these changes in conversation. In order to detect these changes, we consider the evolution of the detected change, using the Bayesian Information …

Volume Phase Transitions In Surface-Tethered, Photo-Cross-Linked Poly(N-Isopropylacrylamide) Networks, Ajay Kumar Vidyasagar

USF Tampa Graduate Theses and Dissertations

The overall thrust of this dissertation is to gain a comprehensive understanding over the factors that govern the performance and behavior of ultra-thin, cross-linked polymer films. Poly(NIPAAm) was used as a model polymer to study volume phase transition in surface tethered networks.

Poly(NIPAAm) undergoes a reversible phase transition at approximately 32°C between a swollen hydrophilic random coil to a collapsed hydrophobic globule state, thought to be caused by increased hydrophobic attractions between the isopropyl groups at elevated temperatures. We present a simple photochemical technique for fabricating structured polymer networks, enabling the construction of responsive surfaces with unique properties. The approach …

The Relationship Between Fam5c Snp (Rs10920501) Variability, Metabolic Syndrome, And Inflammation, In Women With Coronary Heart Disease, Jennifer L. Cline

USF Tampa Graduate Theses and Dissertations

The leading cause of death among women is coronary heart disease (CHD), a multifactorial disease with polygenic heritability estimated at 50%. Polymorphisms in the family with sequence similarity 5, member C' (FAM5C) gene have been associated with myocardial infarction (MI), and one single-nucleotide polymorphism (SNP) has partially accounted for linkage in an acute coronary syndrome subset. The linkage peak on FAM5C corresponds directly with a quantitative trait locus for the inflammatory biomarker monocyte chemoattractant protein 1, as well as a linkage peak to metabolic syndrome (MetS). Metabolic syndrome increases the risk of developing CHD, and MI has been …

The Effects Of Aging On Temporal Masking, Susan E. Fulton

USF Tampa Graduate Theses and Dissertations

The ability to resolve rapid intensity and frequency fluctuations in sound is important for understanding speech, especially in real-world environments that include background noise and reverberation. Older listeners often complain of difficulties understanding speech in such real-world environments. One factor thought to influence speech understanding in noisy and reverberant environments is temporal resolution, the ability to follow rapid acoustic changes over time. Temporal resolution is thought to help listeners resolve rapid acoustic changes in speech as well as use small glimpses of speech available in the dips or gaps in the background sounds. Temporal resolution is an ability that is …

Maintaining Biodiversity With A Mosaic Of Wetlands: Factors Affecting Amphibian Species Richness Among Small Isolated Wetlands In Central Florida., Jackie Guzy

USF Tampa Graduate Theses and Dissertations

The biodiversity value of a wetland is linked not only to its position in the landscape relative to other wetlands, but also to its habitat characteristics. I monitored amphibian species richness among 12 small, isolated, and undisturbed wetlands (which occur on lands permitted for phosphate mining) in central Florida during the 2005 and 2006 breeding seasons. I used seven habitat and landscape variables to characterize the environments of the wetlands and generalized linear models to determine which of these variables had the greatest influence on the occurrence of seven amphibian species (Anaxyrus terrestris, Gastrophryne carolinensis, Hyla gratiosa …

Perspective Taking And Relative Clause Comprehension: A Cross-Modal Picture Priming Study, Nicola C. Jones

USF Tampa Graduate Theses and Dissertations

Fourteen young adults participated in a cross-modal picture priming study. Perspective shift processing, in four types of relative clause sentences and in control sentences, was assessed using reaction times. Predictions were: 1) the easier the perspective shifts, the faster the reaction times and 2) subject relative clauses would reveal a priming effect versus attenuated or no priming in object relative clauses due to difficulty following perspective. A priming effect was observed for 1- switch relative clause sentences and for control sentences, while no priming effect was observed for 0 switch, 1+ switch, or 2 switch sentences. Results suggest that variations …

Gold Nanoparticles And Their Polymer Composites: Synthesis Characterization And Applications, Nidhi Joshi

USF Tampa Graduate Theses and Dissertations

Gold nanoparticles are excellent candidates for all the biomedical applications due to their size and shape dependent optical and physiological properties. In this study, gold nanoparticles were synthesized chemically for bio-application. It was observed that the size and shape of gold nanoparticles depend strongly on the concentration of chemical solution, type of reducing agent used in the reaction, temperature of the solution and stabilizing agent for reaction. Transmission electron microscopy (TEM) has been used extensively to determine the size and shape of the gold nanoparticles. Optical properties of the size and shape selected nanoparticles were studied using UV-vis spectrophotometer in …

Beyond Survival: An Exploration Of Narrative Healing And Forgiveness In Healing From Rape, Heather Curry

USF Tampa Graduate Theses and Dissertations

This work explores: liberatory possibilities and limitations of narrative in healing from rape; the work and meanings of forgiveness, specifically seeking a complex definition of forgiveness drawing on spiritual, feminist, complexity, and phenomenological philosophies; and the relationships between narrative processes and forgiveness. I use an autoethnographic approach, offering my story of rape and healing in the aftermath. I attend to the physicality of the narrative, and to the way in which memory resides in the body, thus creating an embodied text. I examine current models of rape recovery, and the terms used by organizations, practitioners, and authors of rape narratives …

A Comparative Study Of Knowledge Of Pain Management In Certified And Non-Certified Oncology Nurses, Sherrie A. Lalande

USF Tampa Graduate Theses and Dissertations

Over 1.4 million people are diagnosed with cancer annually. Of those people, 70-90% experience some form of pain. Numerous efforts have been made to educate nurses in the management of pain, yet 30-50% of cancer patients report that their pain is poorly managed. It is not clear whether nurses who obtain certification in Oncology are better equipped to manage this patient population regarding their pain issues. This study compared the knowledge of Oncology Certified Nurses (OCN) and Non-Certified Oncology Nurses (NCON) regarding pain management.

The sample of 41 oncology nurses included 19 who were certified in oncology and 22 who …

Moderating The Effectiveness Of Messages To Promote Physical Activity In Type 2 Diabetes, Rachel E. Myers

USF Tampa Graduate Theses and Dissertations

The world is experiencing a rapid rise in chronic health problems, which places an enormous burden on health care services. Modifiable health behaviors such as physical inactivity are largely responsible for this high prevalence and incidence of chronic diseases. Message tailoring is a well-established approach for constructing health communication and has been shown to increase the persuasiveness of messages in the promotion of healthy behaviors. Message framing is an effective strategy that has been well-studied in psychology over the past 20-plus years across a breadth of health-related behaviors but has received little attention in the nursing research literature. Based on …

Electrospinning Protein Nanofibers To Control Cell Adhesion, Cynthia Chinwe Nwachukwu

USF Tampa Graduate Theses and Dissertations

The structural and mechanical properties of a surface often play an integral part in the determination of the cell adhesion strength and design parameters for creating a biodegradable electrospun scaffold. Nanofibers composed of the globular proteins bovine serum albumin (BSA) and fibronectin were produced by electrospinning with the electrospun protein scaffold serving as an extracellular matrix to which adhesion interaction will exist with cells via cell surface integrin. This interaction is vital in regulation cell differentiation, growth and migration and cell adhesion.

We will demonstrate the ability to manipulate ligand-receptor interaction, the properties of the electrospun fibers, control and the …

You Can’T Always Get What You Want, But Does It Matter? The Relationship Between Prechild Preferences And Post-Child Actual Labor Division Fit And Well-Being, Kristen M. Shockley

USF Tampa Graduate Theses and Dissertations

Significant shifts in social ideology and legislation have brought about considerable changes in work and family dynamics in the Western world, and the male as breadwinner-wife as homemaker model is no longer the norm. However, despite increasingly gender egalitarian ideals, the division of labor among dual-earner couples tends to adopt a "neo traditional" once children are born, where women devote more time to family labor and men spend more time in paid employment

Although asymmetrical divisions of labor have clear workplace and societal consequences in terms of women's earnings, organizational advancement, and inequality, the effects on individual well-being are not …

Synthesis, Characterization, And Self-Assembly Of Gold Nanorods And Nanoprisms, Kristina L. Tran

USF Tampa Graduate Theses and Dissertations

The unique properties of gold nanoparticles make them excellent candidates for applications in electronics, sensing, imaging, and photothermal therapy. Though abundant literature exists for isotropic gold nanoparticles, work on nanoparticles of different shapes has been gaining interest recently. Anisotropic gold nanoparticles, such as nanorods and nanoprisms, have tunable optical properties in the visible and near-infrared regions. Through synthesis and surface modification, the production of various shapes of these gold nanoparticles can be controlled to meet different applications.

Two different types of gold nanorods were used in this thesis. The first type was stabilized with cetyltrimethylammonium bromide (CTAB) and had aspect …

Ecological, Behavioral, And Curricular Interventions To Prevent Student Problem Behavior: An Approach To Implementing Effective Practices, Lindsey M. Merritt

USF Tampa Graduate Theses and Dissertations

While classroom management has been a highly researched topic in Applied Behavior Analysis, there are few empirically validated methods to effectively disseminate classroom techniques into school settings. There are three main classroom management areas that exist in the literature. These are: a) ecological factors, b) behavior principles, and c) curricular modifications. These three areas have been researched independently and in combination to find best classroom management practices. Although these areas are highly researched, dissemination of these materials into public and private classrooms has fallen far behind. However, researchers are finding specific variables that positively influence the success of programs in …

Triptych Cultural Critique: Fray Angelico Chavez And Southwestern Critical Regionalism, 1939-2004, Melina Vizcaíno-Alemán

American Studies ETDs

Fray Angelico Chavez was a Franciscan priest and man of letters whose published writings span most of the twentieth century. The dissertation is a critical biography of Fray Angelico's writing, and it uses religion as a critical lens for understanding his work in relation to a host of other Southwestern regional writers, both Anglo and Mexican American. I argue Fray Angelico's Franciscanism fosters a mode of Southwestern critical regionalism in his writing. The main objective of this dissertation is to build and apply a comparative methodology that I call triptych cultural critique to understand better the different modes of regional …

Concepts Of Variable In Middle-Grades Mathematics Textbooks During Four Eras Of Mathematics Education In The United States, James K. Dogbey

USF Tampa Graduate Theses and Dissertations

This study used content analysis to investigate the development of the concept of variables in middle grades mathematics textbooks during four eras of mathematics education in the United States (New Math, Back to Basics, Problem Solving, and the NCTM Standards era: 1957 – 2009). It also examined the nature of support that the curricula provide for teachers to enact variables ideas in the classroom. Findings revealed that each of the middle grades mathematics curricula examined used variables, but in varied proportions and levels of complexity. Formal definitions for variables were found in 11 of the …

Effect Of Catalyst Preparation Conditions On The Performance Of Eggshell Cobalt/Sio2 Catalysts For Fischer-Tropsch Synthesis, Syed Ali Z. H Gardezi

USF Tampa Graduate Theses and Dissertations

A highly selective eggshell Fischer-Tropsch catalyst has been fabricated via interaction of hydrophobic and hydrophilic molecules on thermally treated silica gel. The physical interactions of the mesoporous silica support and the effect of catalyst preparation conditions on the performance of the cobalt/SiO₂ were explored. It was found that dispersion and performance of the FT cobalt/SiO₂ catalyst were significantly affected by the preparation technique used. In this study we focus on two key variables: the solvent used during the precursor loading and the calcination atmosphere. Silanol groups on the silica surface and near-surface regions can alter morphology and dispersion …

La Vida En La Ficción Como Forma De Reescritura De La Historia Oficial En La Novela Caballeros De Fortuna De Luis Landero, Maria Elena Arroyo

USF Tampa Graduate Theses and Dissertations

In this thesis we will study Luis Landero's Novel, Caballeros de fortuna, specifically the creation by the characters of an alternate life that they create through fiction. As a result of a failed life that resembles the effect of the years that Spain experienced Francisco Franco's dictatorial regime, these characters, unable to fight insecurity and rootlessness produced by the society of this era, become victims of utopian desires that result in the creation of an alternative life lived in fiction. At the same time, we can observe how this life style leads to the emergence of a critical study …
