Examining The Potential Unintended Effects Of A Healthful Living Curriculum Upon Children’S Weight-Related Beliefs, Body Satisfaction, And Body Build Stereotypes, Jennifer Paff Ogle, Jan Carroll, Brian Butki, Mary Lynn Damhorst Dec 2008

Examining The Potential Unintended Effects Of A Healthful Living Curriculum Upon Children’S Weight-Related Beliefs, Body Satisfaction, And Body Build Stereotypes, Jennifer Paff Ogle, Jan Carroll, Brian Butki, Mary Lynn Damhorst

Journal of Youth Development

This exploratory work was guided by the question of whether health education messages about food and exercise might inadvertently influence children’s beliefs about weight controllability, body satisfaction, weight self-assessments, desire to alter weight, and body build stereotypes. Participants were 80 children (38 boys, 42 girls) aged 7 to 13 years enrolled in a week-long “FunLIFE” summer camp offered at a large university. FunLIFE was created in response to the childhood obesity crisis and focuses upon Learning to Improve Fitness and Eating (thus, the acronym “LIFE”). Pre- and posttest questionnaires were administered at four camp sessions. Findings indicated that participation in …

The Development And Analysis Of A Closed System Of Vitrification For Mammalian Embryos, Jennifer Graves-Herring Dec 2008

The Development And Analysis Of A Closed System Of Vitrification For Mammalian Embryos, Jennifer Graves-Herring

All Dissertations

Embryo cryopreservation is an integral part of assisted reproduction because it allows for future use of these embryos. Cryopreservation occurs when there are supernumerary embryos or when an embryo transfer cannot be performed.
There are two main methods to cryopreserve embryos. The most recent is vitrification, which uses high concentrations of cryoprotectants, a short time to cool and avoids ice crystals. The 'gold standard' is the slow-cool method, which uses low concentrations of cryoprotectants, a long time to cool embryos and produces extracellular ice crystals.
Prior to introducing vitrification as part of the human cryopreservation regime, it is important that …

'Fabrication And Characterization Of Polymer Blends And Composites Derived From Biopolymers', Suraj Sharma Dec 2008

'Fabrication And Characterization Of Polymer Blends And Composites Derived From Biopolymers', Suraj Sharma

All Dissertations

This research focuses on fabricating blends and composites from natural polymers especially from proteins and natural epoxy, and describing the properties of plastics made from them. Specifically, plastic samples from partially denatured feathermeal and bloodmeal proteins, derived from the animal co-products (rendering) industry, were successfully produced through a compression molding process. The modulus (stiffness) of the material obtained was found to be comparable with that of commercial synthetic materials, such as polystyrene, but was found to have lower toughness characteristics, which is a common phenomenon among plastics produced from animal and plant proteins. Therefore, this study explored blending methods for …

Characterization Of Vascular Smooth Muscle Cell Mechanical And Frictional Properties Using Atomic Force Microscopy, Jason Hemmer Dec 2008

Characterization Of Vascular Smooth Muscle Cell Mechanical And Frictional Properties Using Atomic Force Microscopy, Jason Hemmer

All Dissertations

A working hypothesis within the Laboratory of Vascular Research is that mechanical loading on vascular smooth muscle cells (VSMCs), especially due to solid contact from endovascular devices, contributes to the development of restenosis. In order to better understand the role of mechanical loading on VSMCs in vascular disease development, it is imperative to understand the mechanical properties of VSMCs themselves. To measure the viscoelastic and frictional properties of living VSMCs in an in vitro setting, an atomic force microscope (AFM) was utilized, thereby allowing for mechanical testing of living cells in a fluid environment. In the first phase of research, …

Human Microvasculature Fabrication Using Thermal Inkjet Printing Technology, Xiaofeng Cui Dec 2008

Human Microvasculature Fabrication Using Thermal Inkjet Printing Technology, Xiaofeng Cui

All Dissertations

The current tissue engineering paradigm is that successfully engineered thick tissues must include vasculature. As biological approaches alone such as VGEF have fallen short of their promises, one may look for an engineering approach to build microvasculature. With the advent of cell printing, one may be able to build precise human microvasculature with suitable bio-ink. Human Microvascular Endothelial Cells (HMVEC) and fibrin were studied as bio-ink for microvasculature construction. Endothelial cells are the only cells to compose the human capillaries and also the major cells of blood vessel intima layer. Fibrin has been already widely recognized as tissue engineering scaffold …

Fabrication And Optical Properties Of Noble Metal Nanostructures, Mark Kinnan

All Dissertations

Experimental and theoretical results are presented in Chapters 2, 3, and 4 on the effects of dielectric medium, particle size, and interparticle distance, respectively, on plasmon coupling in two-dimensional arrays of silver nanoparticles. The arrays were fabricated via the self-assembly of single crystal particles from c.a. 46 nm to 287 nm on PVP-modified glass substrates. Spin-coated poly(methylmethacrylate) layers were used to immobilize the particles and prevent their surface aggregation. Varying the thickness of the PMMA layer made it possible to change the average dielectric medium between the particles. UV-Visible spectra of different arrays were compared to the corresponding electron microscope …

Effect Of Clinically Relevant Mechanical Forces On Smooth Muscle Cell Response In Model Of Balloon Angioplasty, Kara Acampora Dec 2008

Effect Of Clinically Relevant Mechanical Forces On Smooth Muscle Cell Response In Model Of Balloon Angioplasty, Kara Acampora

All Dissertations

Restenosis remains a common problem affecting the patency of endovascular intervention such as balloon angioplasty and stent placement as treatments for atherosclerosis. Denudation of the endothelial layer and the increased injury from balloon deployment can cause phenotypic changes in surrounding vascular smooth muscle cells (SMCs) in vivo. The presented work modeled this mechanical environment in vitro to investigate the role of the altered mechanical environment on the phenotypic response of SMCs. Through the system design and CFD channel characterization, a six-independent-channel system providing low oscillating wall shear stress (WSS) was manufactured to apply concurrent shear and tensile forces with uniform …

Synthesis, Characterization, And Application Of Ag Nanostructures, Stephen Hudson Dec 2008

Synthesis, Characterization, And Application Of Ag Nanostructures, Stephen Hudson

All Dissertations

Noble metal nanoparticles (NPs) have been used for many centuries; however their properties were not truly scrutinized until Michael Farady's investigations in the 1850's. Advances in the field of nanotechnology over the last three decades have enabled insights into the properties of materials as their dimensions are reduced to the nanoscale. The repercussions of these insights are seen in many modern applications.
In this dissertation, properties of novel nanostructures based on Ag NPs are presented and discussed. The exceptional optical properties of Ag NPs stem from the collective oscillations of the conduction electrons known as plasmon resonances. The excitation of …

Agritourism As A Viable Strategy For Economic Diversification: A Case Study Analysis Of Policy Options For The Bahamas, Erecia Hepburn Dec 2008

Agritourism As A Viable Strategy For Economic Diversification: A Case Study Analysis Of Policy Options For The Bahamas, Erecia Hepburn

All Dissertations

This research examines the prospects for developing an economic diversification policy for The Bahamas, utilizing agritourism. The Bahamas is plagued with the dominance of one traditional sector, tourism combined with the lack of economic innovation and the inability to maintain domestic demand for food security, which has the potential for economic crisis if there are any serious 'external shocks' or setbacks in mainstream tourism. Such a possible drop in tourism is most evident from experiences in 2001 with the Straw Market fire of Sept 4th, and the terrorist attacks in America on September 11th, coupled with the escalating cost of …

Vascular Tissue Engineering: The Creation Of Living, Non-Thrombogenic, Functional Blood Vessels Based On Elastin Scaffolds, Aditee Kurane Dec 2008

Vascular Tissue Engineering: The Creation Of Living, Non-Thrombogenic, Functional Blood Vessels Based On Elastin Scaffolds, Aditee Kurane

All Dissertations

Cardiovascular diseases are the leading cause of death worldwide. Blood vessel replacement is a common treatment for vascular diseases such as atherosclerosis, restenosis and aneurysm, with over 300,000 bypass procedures performed each year. However, vein grafts are limited due to their availability. Although synthetic vascular replacements have been successful for large diameter arteries, they have shown minimal success in arteries with diameters <6mm. This is because most synthetic materials induce thrombus formation which, within a few months of implantation, causes failure of the vascular graft due to occlusion. Tissue engineering is a promising approach to the fabrication of non-thrombogenic vascular grafts, but a reliable and expandable cell source for tissue-engineered vascular graft (TEVG) has not been established.
The work presented here is motivated by the current unavailability of an ideal tissue engineered blood vessel replacement. Our overall goal is to create a living tissue engineered vascular graft that is biodegradable, non-thromobogenic, presents low antigenicity and …

Institutional Culture, Performance, And Learning In A Two-Year Technical/Community College, Vicky Maloney Dec 2008

Institutional Culture, Performance, And Learning In A Two-Year Technical/Community College, Vicky Maloney

All Dissertations

The environments of higher education institutions have undergone significant changes in the past twenty years as a result of concerns expressed in prominent reports. These external concerns and initiatives reflect contemporary criticisms by the public about the efficiency and effectiveness of the performance of institutions. The response from research, legislatures, and the institutions has been to implement practices aimed at improvement and borrowed from business and industry. Research indicates that this performance orientation to change in higher education has largely failed, due in part to the lack of attention given to the culture of the institution.
Emerging research indicates a …

Functional Characterization Of Hexokinase-Like 1 (Hkl1) From Arabidopsis Thaliana, Abhijit Karve Dec 2008

Functional Characterization Of Hexokinase-Like 1 (Hkl1) From Arabidopsis Thaliana, Abhijit Karve

All Dissertations

Arabidopsis hexokinase1 (AtHXK1) is a moonlighting protein with roles in both glucose signaling and catalysis. In this study, we first cloned and characterized the six HXK related genes from Arabidopsis. Three of the six encoded proteins were shown not to phosphorylate hexoses and thus, are designated as hexokinase-like (HKL) proteins. Though they are only 50% identical to HXK1, the amino acid sequences of HKL1 and HKL2 both have well conserved glucose binding domains and other recognized structural elements. The possible basis for their lack of catalytic activity was further probed by site-directed mutagenesis and ultimately was attributed to a suite …

Mother Load, Jeanine Garrett

All Theses

In this body of work I interweave elements of the Catholic Rite of Reconciliation and that of the domestic realm to explore the tension between idealistic expectations within American culture and the imperfect realities of everyday life. I chose to create a sculptural installation for its unique ability to allow the audience to be immersed in its visual and conceptual questions. By drawing on my own experience of struggling to fulfill an ideal, the work should encourage my audience to consider the wide range of social tensions that they themselves are faced with.
My installation is deeply engaged in the …

Discarded To The Transcendent, Robert Brownlow Dec 2008

Discarded To The Transcendent, Robert Brownlow

All Theses

My current body of work strives to elevate the discarded to the transcendent, to take the unwanted and bring it to new life. I choose to transform materials in a way that challenges perceptions of space and material. The work also serves to create an experience for the viewer, an experience that may allow an escape from the mundane of every day life and journey, for a moment, to a world that embraces unexpected emotion.
With obsolescence in mind, I tend to use materials that are found throughout scrap yards, surplus warehouses, and anywhere else I may find underutilized materials …

Application Of Web Services To A Simulation Framework, Matthew Bennink Dec 2008

Application Of Web Services To A Simulation Framework, Matthew Bennink

All Theses

The Joint Semi-Automated Forces (JSAF) simulator is an excellent tool for military training and a great testbed for new SAF behaviors. However, it has the drawback that behaviors must be ported into its own Finite State Machine (FSM) language. Web Services is a growing technology that seamlessly connects service providers to service consumers. This work attempts to merge these two technologies by modeling SAF behaviors as web services. The JSAF simulator is then modeled as a web service consumer.
This approach allows new Semi-Automated Forces (SAF) behaviors to be developed independently of the simulator, which provides the developer with greater …

From The Gilded Ghetto To Hollywood: Bruce Lee, Kung Fu, And The Evolution Of Chinese America, Darcy Coover

All Theses

As has been true for most groups of immigrants arriving in the United States, the Chinese have undergone a wide-ranging, and at times rapid, transformation in the eyes of mainstream America. No other ethnic or racial group in American history has been so singled out for immigration regulation as have the Chinese--the Exclusion Act, passed in 1882, still represents the only time that a particular ethnic group was selected for immigration restriction. While an analysis of the legal history of the era reveals the various restrictions faced by Chinese immigrants in terms of the state, a look at American popular …

Insights Into Biogeophysical Signatures Using Polarization Force Microscopy, Elizabeth Bartosik Dec 2008

Insights Into Biogeophysical Signatures Using Polarization Force Microscopy, Elizabeth Bartosik

All Theses

The success of bioremediation strategies is dependent upon effective monitoring of microorganisms in the subsurface. Induced polarization (IP) may represent a cost-effective, complementary technique to existing borehole-based microbe detection schemes. Recent studies show a significant, yet poorly understood IP effect associated with the presence of bacteria in aqueous and porous media. This effect is believed to be rooted in the physicochemical surface interactions between cells and minerals which we probe using polarization force microscopy. Polarization force experiments were conducted on a hydrated mica surface using the gram positive bacterium Bacillus subtilis and the gram negative bacterium Escherichia coli. On all …

Computational Analysis Of Input-Shaping Control Of Microelectromechanical Mirrors, Thomas Starling Dec 2008

Computational Analysis Of Input-Shaping Control Of Microelectromechanical Mirrors, Thomas Starling

All Theses

Advances in micromachining technology have enabled the design and development of high performance microelectromechanical systems (MEMS). There is a pressing need for control techniques that can be used to improve the dynamic behavior of MEMS such as the response speed and precision. In MEMS applications, open-loop control is attractive as it computes a priori the required system input to achieve desired dynamic behavior without using feedback, thus eliminating the problems associated with closed-loop MEMS control. While the input-shaping control is attractive due to its simplicity, the effectiveness of this control approach depends on the accuracy of the model that is …

New American Witches: A Transitioning Figure In The Twentieth Century, Daniel Grafton Dec 2008

New American Witches: A Transitioning Figure In The Twentieth Century, Daniel Grafton

All Theses

This thesis compares the Wiccan faith with fantasy literature of the twentieth century in an effort to reveal the spread of radical feminist thought between 1963 and 1983 by examining how these groups represented the shared figure of the witch. By comparing these different representations it may be determined whether radical feminist thought was promoted through fantasy literature. If the figure of the witch did become radically feminist in this popular setting then this would indicate a broader acceptance of radical feminist thought in American culture. This is examined by establishing a definition of fantasy literature during the late twentieth …

Transformation Of Sulfonamide Antibiotics On Soil Mineral Oxides, Baishu Guo

All Theses

Determining the occurrence and potential adverse effects of antibiotic pharmaceuticals released into the environment is a critical step towards responsible environmental stewardship. Under aqueous conditions typically found in soils and natural waters, the antibiotic agent sulfamethoxazole (SMX) was transformed in the presence of pyrolusite MnO2 via oxidative pathways. At least 50% loss of SMX was observed after 269 hr in acidic and basic solutions (pH 3-9). A maximum of 100% loss was recorded at pH 3 and 66% loss was recorded at circumneutral pH. Concomitantly, aqueous manganese concentrations increased to around 10 µM at pH 3 and 2 µM at …

Mouthful Idol, Claudia Dishon

All Theses

In my work, I create an imaginative realm as a means to structure chaos. This fictional realm is a place to manifest my perceptions of the world. In alignment with my world view, the pieces exhibit multi-faceted sprays of information meant to explain a more rounded picture of reality. Mental clutter becomes visual clutter when realized in my prints. Recognizable objects, animals, foods, herbs, and written text are layered to form compositions that function abstractly at a distance. A closer inspection reveals identifiable forms within the layers of color and shape.
Haphazard imagery receives the same attention and support as …
