How Do Planners Participate In Formulating Viable Green Infrastructure Plans?, Kaylen Francis
How Do Planners Participate In Formulating Viable Green Infrastructure Plans?, Kaylen Francis
All Theses
The planning field is increasingly involved in balancing biodiversity with the expansion of urban areas to meet changing societal demands. Regions, states and cities have begun trying to mitigate the negative effects of sprawl by creating green infrastructure plans to conserve open space. However, little is known about planners' roles in facilitating and/or implementing these visions in cities with a population of over one million people in the core and hinterlands. The goal of this project was to study the Chicago Wilderness Green Infrastructure Vision to determine if planners played a role in its formulation and/or implementation, and if so, …
Assessment Of Conceptual Understanding Of Atomic Structure, Covalent Bonding, And Bond Energy, Alma Gonzales
Assessment Of Conceptual Understanding Of Atomic Structure, Covalent Bonding, And Bond Energy, Alma Gonzales
All Theses
This research work relied upon the importance of conceptual understanding to meaningful learning. Conceptual understanding is strongly influenced by students' prior knowledge (1). Many of these ideas pose strong barriers to deeper understanding and are called misconceptions since they are inconsistent or in conflict with generally accepted scientific facts (2). Thus, it is beneficial for instructors to initially elicit students' conceptual understanding in order to properly address student's misconceptions during the learning process. However, results are very dependent on the instrument used to elicit conceptual understanding (3). The most commonly used tools are summative assessments or achievement tests (4). They …
A Study Of The Biltmore Estate's Ramble: Researching Design Intent, Evaluating Change Over Time, And Proposing A Rehabilitation Plan, Owen Mclaughlin
A Study Of The Biltmore Estate's Ramble: Researching Design Intent, Evaluating Change Over Time, And Proposing A Rehabilitation Plan, Owen Mclaughlin
All Theses
The purpose of this study is to propose a historically appropriate rehabilitation plan for the Biltmore Estate's Ramble based upon Olmsted's original design intent. In order to ascertain Frederick Law Olmsted's original design intent for the Ramble, an extensive review of Victorian Era garden design, cultural landscapes, the U.S. Horticultural Industry, and possible design influences on Olmsted as he designed the site was performed. Using primary archival materials and secondary sources, the developmental history of the Ramble from 1890 to present was studied. From that work, design intent was determined by analyzing character-defining features from the original 1893 planting plan …
Evaluating The Impacts Of Production Process And Product Origin On Willingness To Pay For Shrimp, Addison Ellis
Evaluating The Impacts Of Production Process And Product Origin On Willingness To Pay For Shrimp, Addison Ellis
All Theses
The 2002 Farm Bill included a provision requiring various agricultural commodities to comply with country of origin labeling (COOL). Proponents of COOL argued that the policy would support U.S. producers and benefit U.S. consumers. This argument was based on the assumption that U.S. consumers prefer domestic products to imported products and hence the demand for U.S. products would increase following the implementation of COOL. However, analyzing the impact of COOL on shrimp, one of the first commodities covered the program, is complicated by recent trade disputes, concerns over the safety of farm raised products and potential stigma effects associated with …
Open Source Rigging In Blender: A Modular Approach, Ryan Cushman
Open Source Rigging In Blender: A Modular Approach, Ryan Cushman
All Theses
Character rigs control characters in the traditional CG pipeline. This thesis examines the rig creation process and discusses several problems inherant in the traditional workflow--excessive time spent and a lack of uniformity, and proposes a software plugin which solves these issues. This thesis describes the creation of a tool for Blender 3D which automates the rigging process yet keeps the creativity and control in the hands of the user. A character rig designed by this tool will be fully functional--yet capable of being split into its component parts and reconstructed as the user determines. These body parts are individually scripted …
Examination Of Qualitative Methodology Usefulness In Assessing Management Effectiveness Of Protected Areas: A Case Study Of Mexico, Carla Mora-Trejos
Examination Of Qualitative Methodology Usefulness In Assessing Management Effectiveness Of Protected Areas: A Case Study Of Mexico, Carla Mora-Trejos
All Theses
Parks and Protected Areas (PAs) are an important approach for conservation of cultural and natural diversity worldwide (Bruner 2001; McNeely 1994; Rao & Geisler 1990). Their long term success depends on effective management in relation to the goals set forth for the PA. Measuring this can be complex and challenging and has been done in a variety of ways in order to better get at the answer of how to measure management effectiveness. The purpose of this research was to develop and test qualitative methodology designed to explore management effectiveness using all six elements from the WCPA framework (Hockings et …
Wounded Planet, Wounded People: The Possibility Of Ecological Trauma, Lauren Woolbright
Wounded Planet, Wounded People: The Possibility Of Ecological Trauma, Lauren Woolbright
All Theses
In recognizing that the human relationship to the nonhuman natural world has been characterized primarily by trauma, we might notice that humans abuse landscapes and deplete resources, harming the very ecosystems that support us, moving on when they no longer can or using technology in order to remain. This might be seen as a double trauma in which the human traumatizes ecosystems, which are then traumatic to the human. Our unwillingness as a culture to consider the nonhuman natural world as a valuable subject capable of experiencing trauma prevents us from understanding the repercussions of our actions. Spivak's theory offers …
Biodiesel Production Using Chemical And Enzymatic Catalysts And Improvement Of Cold Flow Properties Using Additives, Hem Joshi
All Dissertations
Biodiesel production was carried out from soybean, canola and cottonseed oils along with poultry fat using catalytic potassium hydroxide. Further, the physical properties of biodiesel were studied with addition of ethyl levulinate (ethyl 4-oxopentanoate), short-chain alcohols (ethanol, isopropanol and butanol), and commercial cold flow improver (CFI) additives. The effects of adding ethyl levulinate, short-chain alcohols, and commercial additives were determined by studying their influence on the acid value (AV), cloud point (CP), pour point (PP), cold filter plugging point (CFPP), induction period (IP), kinematic viscosity (KV) and the flash point (FP). The results showed improved low temperature properties of the …
Information Seeking Behavior: The Effects Of Relationalism On The Selection Of Information Sources, Chris Zimmer
Information Seeking Behavior: The Effects Of Relationalism On The Selection Of Information Sources, Chris Zimmer
All Dissertations
In a world where 'Google' is a verb, this research asks the question 'what influences an individual's decision to select one information source over another?' Previous works have discussed relational versus nonrelational information sources (Rulke, Zaheer, & Anderson, 2000). Other research focuses on the information quality (O'Reilly, 1982), source accessibility (Culnan, 1984, 1985), or source richness (Daft, Lengel, & Trevino, 1987; Daft & Macintosh, 1981) but all these prior works do not address the social aspects of information sources.
This research defines and develops the construct of relationalism which is reflective of the social aspects of information sources. An important …
Regulation Of Trypanosoma Brucei Hexokinase 1 And 2 On Multiple Levels: Transcript Abundance, Protein Expression And Enzyme Activity, Heidi Dodson
All Dissertations
Trypanosoma brucei, a unicellular eukaryotic parasite, is the causative agent of African sleeping sickness in sub-Saharan Africa. The parasite encounters two main environments as it progresses through its life cycle: the tsetse fly and the mammalian
bloodstream. Nutrient availability is distinct in the two environments, requiring the parasite to utilize diverse metabolic pathways to efficiently produce ATP for survival. Bloodstream form parasites (BSF), residing in a glucose rich environment, rely solely on
glycolysis for energy, while procyclic form (PF) parasites metabolize readily available proline and threonine in addition to glucose.
T. brucei expresses two hexokinases, the first enzyme in the …
The Ethics Of Obstruction, Joshua Abboud
The Ethics Of Obstruction, Joshua Abboud
All Dissertations
This work engages the film The Five Obstructions (2003) as a configuration for multimodal composition. It explores a theory of general composition as a matter of confronting obstructions or creative constraints as a process of collaborative revision and pedagogy. Writing in this context constitutes ethical responses to the shifting constraints of communication and signification. The obstructions performed by the film as a series of revisions offer sources of proliferating rhetorical invention and play grounded on negotiated fields of operations.
The first two chapters explore the relations between image and ethics in a pedagogy of revision, while the third considers the …
Activities Of Muscadine Grape Skin And Polyphenolic Constituents Against Helicobacter Pylori, Joseph Brown
Activities Of Muscadine Grape Skin And Polyphenolic Constituents Against Helicobacter Pylori, Joseph Brown
All Dissertations
Helicobacter pylori is a microaerophilic, gram-negative bacterium and among the most persistent of all human pathogens. Its presence in the gastric environment is corre-lated with diseases such as gastritis, peptic ulcers, mucosa-associated lymphoid tissue lymphoma, and gastric carcinoma. Multiple factors are believed responsible for disease progression and outcome including infecting strain(s) genetic composition, age of acqui-sition, host immune response, environment, and diet. Due to the complexity of H. pylori infection, all possible host-pathogen interactions should be considered. One important factor frequently underplayed is host dietary habits which may serve a more important role during and immediately following infection with H. …
Synthesis, Characterization, And Reactivity Of Biologically Relevant Copper(I) Selone And Thione Complexes, Martin Kimani
Synthesis, Characterization, And Reactivity Of Biologically Relevant Copper(I) Selone And Thione Complexes, Martin Kimani
All Dissertations
In Fenton-like reactions, Cu+ localized on DNA reduces hydrogen peroxide to form hydroxyl radical (*OH), resulting in oxidative DNA damage. This DNA damage causes mutation and cell death, which can lead to diseases such as cancer, Alzheimer's, and arteriosclerosis. Sulfur and selenium antioxidants have been investigated for the prevention and treatment of these diseases, and studies have shown that sulfur- and selenium-containing antioxidants prevent DNA damage from copper-generated hydroxyl radical and that metal coordination is required for the observed antioxidant activity.
To determine how copper coordination results in DNA damage inhibition, Cu+ complexes with selone and thione ligands were synthesized …
Cellulose Nanocrystals Properties And Applications In Renewable Nanocomposites, Esteban Urena Benavides
Cellulose Nanocrystals Properties And Applications In Renewable Nanocomposites, Esteban Urena Benavides
All Dissertations
Development of novel bio-based nanocomposites is fundamental to reduce the dependence on fossil resources and provide a sustainable future. In light of this global problem, cellulose nanocrystals (CNCs) have raised interest due to their remarkable mechanical properties. Adequate design of nanocomposites requires a fundamental understanding of how the structure affects the mechanical properties of the material. However, contradictory results in the literature have revealed a lack of comprehension of this relationship for CNC based composites. Consequently, this work provides an explanation to unusual results for CNC nanocomposites presented in the literature and demonstrates the ability to achieve property enhancements in …
Characterization Of Piedmont Prairie Sites In North And South Carolina, James Benson
Characterization Of Piedmont Prairie Sites In North And South Carolina, James Benson
All Dissertations
Grassland habitats have essentially disappeared from the Piedmont. This study was conducted to determine which site characteristics in remnant Piedmont prairie sites could be used as indicators of suitable sites. Eight prairie remnant sites located in the Piedmont of North and South Carolina were evaluated based on soil series, slope, aspect, landform index, temperature, and precipitation. Geographic Information System technology was used to create layers of these characteristics to predict potential restoration sites throughout the North and South Carolina Piedmont. It was found that southern aspects, slopes generally less than 15%, upper slope positions, and occurrence on Enon (Fine, mixed, …
Comparative Forelimb Muscle Function In Turtles: Tests Of Environmental Variation And Neuromotor Conservation, Angela Rivera
Comparative Forelimb Muscle Function In Turtles: Tests Of Environmental Variation And Neuromotor Conservation, Angela Rivera
All Dissertations
Novel locomotor functions in animals may evolve through changes in morphology, muscle activity, or a combination of both. The idea that new functions or behaviors can arise solely through changes in structure, without concurrent changes in the patterns of muscle activity that control movement of those structures, has been formalized as the `neuromotor conservation hypothesis'. In vertebrate locomotor systems, evidence for neuromotor conservation is found across transitions in terrestrial species and into fliers, but transitions in aquatic species have received little comparable study to determine if changes in morphology and muscle function were coordinated through the evolution of new locomotor …
Fluid Dynamics Of Cell Printing, Ping He
Fluid Dynamics Of Cell Printing, Ping He
All Dissertations
Cell printing is an emerging technology that uses droplets to deliver cells to desired positions with resolution potentially comparable to the size of single cells. In particular, ink–jet based cell printing technique has been successfully used to build simple bio–constructs and has shown a promise in building complex bio–structures or even organs. Two important issues in ink–jet based cell printing are the moderate survival rate of delicate cells and the limited cell placement resolution. Resolving these issues is critical for the ink–jet based cell printing techniques to realize their full potential.
In this work, we use numerical simulations to reconstruct …
Electromechanics Of Biological Systems Studied By Scanning Probe Microscopy, Gary Thompson
Electromechanics Of Biological Systems Studied By Scanning Probe Microscopy, Gary Thompson
All Dissertations
The functional role of piezoelectricity and of other modes of electromechanical coupling across the hierarchical structures of biological materials garnered interest many years ago. Many biological materials have been described as exhibiting piezoelectric behavior, from wool fibers to wood planks and even to living mammalian cells, but efforts are on-going towards understanding how electromechanical coupling in biological systems transcends from the molecular to tissue levels.
In pursuit of high-resolution measurements of such hierarchical electromechanical coupling, scanning probe microscopy-based techniques are considered. Piezoresponse force microscopy (PFM) becomes the specific focus of this work, and the nascent development of PFM is reviewed …

The Healing Species: Animal-Assisted Character Education For Improving Student Behavior, Wanda Pearson
The Healing Species: Animal-Assisted Character Education For Improving Student Behavior, Wanda Pearson
Journal of Youth Development
The Healing Species program aims to reduce disruptive behaviors at school by increasing students’ abilities to avoid conflict when possible and to resolve conflicts peaceably when they occur. The program’s 11 lessons incorporate elements of behavior theory that postulate behavior follows belief. This study hypothesized that 5th and 6th grade students who completed the Healing Species curriculum would show fewer normative beliefs favoring aggression, greater empathy, and fewer disciplinary infractions, than a comparable group of students who did not receive the Healing Species program. Lessons included the participation of rescued dogs to emphasize compassion, empathy, responsibility, and forgiveness. Study results …
