Show moreThis study attempts to identify normalization cues within multimodal scholarship to highlight moments of (")un-seeing(") multimodal composing practices and theoretical contributions from non-Western traditions. Advocates of this approach to teaching composition understand it as an effective way for incorporating other voices into the curricular structures of composition courses. However, the instructional resources do not include or cite research that does not lend itself easily to dominant views of composing within academia. I assert that academia must go further with how value is assessed. There is research that acknowledges the multiliteracies practices found within subcultures of America, and plenty of work that deems the communicative practices observed in these subcultural communities as valuable. However, it is more than just including and citing scholarship from and about people of color's compositional practices, academia must also employ these ways of knowing and being to fully empower students and utilize the knowledge that the students bring with them to the FYC classroom. The dominant assignment genre in academia is the academic essay. Other dominant methods of communication and transferring scholarship are the journal article, annotated bibliography, proposal, and personal essay. Not to mention the many scholars who have critiqued academia for privileging print literacies, which although may be multimodal, promotes a multimodality of one culture and ideological standpoint. Although the seminal texts from the study offer exceptional multimodal composition research and classroom resources, if we can agree that (")the mission of education is to ensure that all students benefit from learning in ways that allow them to participate fully in public, community, and economic life(") and that literacy pedagogy, essentially what the FYC course offers, (")is expected to play a particularly important role in fulfilling this mission,(") then failing to see the value and utilize the scholarship from and about people of color ensures those that are marginalized continue to be (")un-seen(") and students remain unprepared for the tasks of composing and communicating outside of school (New London Group 60).

Title: EDUCATIONAL HANDHELD VIDEO: EXAMINING SHOT COMPOSITION, GRAPHIC DESIGN, AND THEIR IMPACT ON LEARNING.
Creator: Hutchens, Jason, Taylor, Rosemarye, University of Central Florida
Abstract / Description: Formal features of video such as shot composition and graphic design can weigh heavily on the success or failure of educational videos. Many studies have assessed the proper use of these techniques given the psychological expectations that viewers have for video programming (Hawkins et al., 2002; Kenny, 2002; Lang, Zhou, Schwardtz, Bolls, & Potter, 2000; McCain, Chilberg, & Wakshlag, 1977; McCain & Repensky, 1972; Miller, 2005; Morris, 1984; Roe, 1998; Schmitt, Anderson, & Collins, 1999;...

This study examined formal features within the context of the newly emerging distribution method of viewing video productions on mobile handheld devices. Shot composition and graphic design were examined in the context of an educational video to measure whether or not they had any influence on user perceptions of learning and learning outcomes. The two formal features were modified for display on 24 inch screens and on 3.5 inch or smaller screens. Participants were shown one of the four modified treatments, then presented with a test to measure whether or not the modified formal features had any impact or influence on learning outcomes from a sample of 132 undergraduate college students. No significant differences were found to occur as a result of manipulation of formal features between the treatment groups.

Show moreAn accurate determination of a spacecraft's radio frequency electromagnetic field environment during launch and flight is critical for mission success. Typical fairing structures consist of a parabolic nose and a cylindrical core with diameters of 1 to 5 meters resulting in electrically large dimensions for typical operational sources at S, C and X band where the free space wavelength varies from 0.15 m to 0.03 m. These electrically large size and complex structures at present have internal fairing electromagnetic field evaluation that is limited to general approximation methods and some test data. Though many of today's computational electromagnetic tools can model increasingly complex and large structures, they still have many limitations when used for field determination in electrically large cavities. In this dissertation, a series of test anchored, full wave computational electromagnetic models along with a novel application of the equivalent material property technique are presented to address the electrical, geometrical, and boundary constraints for electromagnetic field determination in composite fairing cavity structures and fairings with acoustic blanketing layers. Both external and internal excitations for these fairing configurations are examined for continuous wave and transient sources. A novel modification of the Nicholson Ross Weir technique is successfully applied to both blanketed aluminum and composite fairing structures and a significant improvement in computational efficiency over the multilayered model approach is obtained. The advantages and disadvantages of using commercially available tools by incorporating Multilevel Fast Multipole Method (MLFMM) and higher order method of moments (HO MoM) to extend their application of MoM to electrically large objects is examined for each continuous wave transmission case. The results obtained with these models are compared with those obtained using approximation techniques based on the Q factor, commonly utilized in the industry, and a significant improvement is seen in a prediction of the fields in these large cavity structures. A statistical distribution of data points within the fairing cavity is examined to study the nature of the fairing cavity field distribution and the effect of the presence of a spacecraft load on these fields is also discussed. In addition, a model with external application of Green's function is examined to address the shielding effectiveness of honeycomb panels in a fairing cavity. Accurate data for lightning induced effects within a fairing structure is not available and hence in this dissertation, a transmission line matrix method model is used to examine induced lightning effects inside a graphite composite fairing structure. The simulated results are compared with test data and show good agreement.

Show moreFiber reinforced polymer (FRP) composites have been of interest to the structural engineering society since the earliest days of FRP composites industry. The use of such systems has been implemented in both new construction and for repair and rehabilitation of existing structures. Since the 1980s, researchers have developed a significant body of knowledge to use FRP composites in infrastructure applications; however, most of this established knowledge was concentrated on the use of traditional epoxy (EP) systems (epoxy matrix FRPs and epoxy adhesives). FRP composites with polyurethane (PU) matrices and adhesives have recently attracted the attention of a few researchers due to their potential advantages in constructibility and mechanical properties. The deployment of these systems is currently limited by a lack of knowledge on mechanical and durability performance. The objective of this research is to quantify the mechanical behavior of PU composites utilized in externally-bonded repair of common flexural and flexural-axial reinforced concrete systems. In addition, the mechanical performance, strength, and failure modes are compared directly with an epoxy-based composite by subjecting reinforced concrete specimens utilizing each of the matrix types (EP and PU) to the same protocols. The study presented therefore allows an objective comparison (advantages and disadvantages) between the two composite system used for repair and rehabilitation of concrete infrastructure. An experimental research program was designed with different length scales. Small-scale experiments were utilized to characterize the component level properties of the materials and bond to concrete, which include the flexural behavior as well as the pure shear behavior. The results of these small scale experiments were used to calibrate analytical models of the interface behavior between FRP laminate and concrete, and paved the way for the next level of the research which studied the behavior of each composite system at larger scales. The large scale experiments included flexural retrofitting of reinforced concrete girders and retrofitting of circular columns using FRP laminates. The large-scale experimental specimens were mechanically damaged prior to FRP repair and testing, making the testing more appropriate compared to common practice of repairing undamaged specimens.

Show moreCurrent approaches to teaching creative writers the ways to success in creative writing courses consist largely of workshop style classes. While workshops often vary from class to class in style, generally a workshop will consist of a group of writers, led by a mentor/instructor, who exchange drafts and provide reader and writer focused feedback to the author. Yet because the workshop approach has not been the subject of close empirical study, it is unclear whether it is an effective pedagogy. This thesis serves two purposes. First, it presents an argument for new research into creative writing pedagogy and creative writers' processes and suggests that any future research should take an empirical turn. However, because creative writing has developed few theories or methods useful for the empirical study of creative writing, I suggest adopting theories and methods from the field of rhetoric and composition. The second part of this thesis is an empirical study of three creative writing undergraduate students in an introductory creative writing course over one semester. This study uses qualitative methods: semi-structured retrospective interviews, close textual analysis, and in-class observations to understand how creative writers are enculturated into the creative writing community using Christine Tardy's theories of acquiring genre expertise as a framework for analysis. Based on this research this study concludes that while creative writers enculturate in different ways, based on several factors, all creative writers develop greater awareness of genre complexity, authorial identity, and intermodal influences on their writing. Furthermore, this study recommends further case studies into creative writers writing processes and the effectiveness of various workshop models on student enculturation. ?

Show morePolymer-derived ceramics (PDCs) are exceptional ultra-high temperature and stable multifunctional class of materials that can be synthesized from a polymer precursor through thermal decomposition. The presented research focuses on 1-D nanofibers, 2-D films and 3-D bulk, carbon-rich silicon carbon nitride (SiCN) ceramics. 1-D nanofibers were prepared via electrospinning for light weight, flame retardant and conductive applications. The commercially available CerasetTM VL20, a liquid cyclosilazane pre-ceramic precursor, was mixed with polyacrylonitrile (PAN) in order to make the cyclosilazane electrospinnable. Carbon-rich PDC nano?bers were fabricated by electrospinning various ratios of PAN/cyclosilazane solutions followed by pyrolysis. Surface morphology of the electro spun nanofibers characterized by SEM show PDC nano?bers with diameters ranging from 100-300 nm. Also, thermal stability towards oxidation showed a 10% mass loss at 623oC. 2-D carbon/SiCN films were produced by drop-casting a mixture of PAN/cyclosilazane onto a glass slide followed by pyrolysis of the film. Samples ranging from 10:1 to 1:10 PAN:cyclosilazane were made by dissolving the solutes into DMF to produce solutions ranging from 1% to 12% by weight. Green, heat-stabilized, and pyrolyzed 8% films were examined with FTIR to monitor the change in chemical structure at each step of the ceramization. SEM shows that high PAN samples produced films with ceramic embedded spheroid components in a carbon matrix, while high cyclosilazane samples produced carbon embedded spheroid.Finally, this research focuses on the challenge of making fully dense, 3-D bulk PDCs materials. Here we present a composite of SiCN with reduced graphene oxide (rGO) aerogels as a route for fully dense bulk PDCs. Incorporation of the rGO aerogel matrix into the SiCN has its pros and cons. While it lowers the strength of the composite, it allows for fabrication of large bulk samples and an increase in the electrical conductivity of the PDC. The morphology, mechanical, electrical properties and thermal conductivity of graphene-SiCN composite with varying rGO aerogel loading (0.3-2.4%) is presented. The high temperature stability, high electrical conductivity and low thermal conductivity of these composites make them excellent candidates for thermoelectric applications. Generally, carbon-rich SiCN composites with improved thermal and electrical properties are of great importance to the aerospace and electronics industries due to their expected harsh operating environments.

Show moreWe investigate the spectra of asteroids at near- and mid-infrared wavelengths. In 2010 and 2011 we reported the detection of 3 ?m and 3.2-3.6 ?m signatures on (24) Themis and (65) Cybele indicative of water-ice and complex organics [1] [2] [3]. We further probed other primitive asteroids in the Cybele dynamical group and Themis family, finding diversity in the shape of their 3 ?m [4] [5] [6] and 10 ?m spectral features [4]. These differences indicated mineralogical and compositional variations within these asteroid populations. Also in the mid-infrared region we studied a larger population of asteroids belonging to the Bus C, D, and S taxanomic classes to understand the relationship between any mineralogy and hydration inferred in the visible and near- infrared with the shape, strength, and slope of the 10 ?m emission. We have discovered that at least 3 of the main Bus taxanomic groups (Cs, Ds, and Ss as defined by their visible spectra) clearly cluster into 3 statistically distinct groups based on their 8-13 ?m spectra. Additionally we have attempted to simulate in a laboratory the possible organic compounds we have detected on two asteroids, using various mixtures containing aromatic and aliphatic hydrocarbons. We find that asteroid (24) Themis and (65) Cybele have ?CH2/?CH3 and NCH2/NCH3 ratios similar to our 3- methylpentane, propane, and hexane residues, suggesting that the organics on these asteroids may be short chained and/or highly branched. The ?CH2/?CH3 and NCH2/NCH3 for asteroid(24)Themis are most consistent with the DISM, and some carbonaceous chondrites. The band centers of the C-H stretch absorptions indicate that both asteroids may have aliphatic carriers chemically bonded to electronegative groups (i.e. aromatics), and some that are not. We also detect a 3.45 ?m feature in the spectra of both asteroids that is present in several dense molecular clouds. Our results suggest an interstellar origin for the organics on (24) Themis, and likely (65) Cybele. The differences in the organics of Themis and Cybele are likely related to variations in thermal processing, irradiation and/or formation region in the solar nebula.

Show moreThis research explores the application of Viewpoints and Composition training with a cast of high school students to measure changes in the social cognitive development (SCD) of individuals and the collective group. The research centers on the writing of Michael F. Mascolo and Deborah Margolis, which takes a coactive approach to the relationship between oneÃƒÂƒÃ‚Â‚ÃƒÂ‚Ã‚Â's social cognitive development and how it is manifested in his or her actions within a social group. Using this framework, the researcher assesses the personality types within the cast and analyzes how utilizing Viewpoints training creates shifts within these personalities. The researcher approaches this study from both a theoretical standpoint as a student during a two-week intensive training course for adults with SITI Company, and a practical standpoint in the direction of a fully mounted production with high school actors. The objective of the research is to propose a method to implement advanced Viewpoints training within a high school ensemble in order to cultivate ensemble and ultimately aid the social cognitive development of the individual actors.

Show moreThis study focuses on developing explicit analytical and numerical process models for mechanical micro-machining of heterogeneous materials. These models are used to select suitable process parameters for preparing and micro-machining of these advanced materials. The material system studied in this research is Magnesium Metal Matrix Composites (Mg-MMCs) reinforced with nano-sized and micro-sized silicon carbide (SiC) particles.This research is motivated by increasing demands of miniaturized components with high mechanical performance in various industries. Mg-MMCs become one of the best candidates due to its light weight, high strength, and high creep/wear resistance. However, the improved strength and abrasive nature of the reinforcements bring great challenges for the subsequent micro-machining process.Systematic experimental investigations on the machinability of Mg-MMCs reinforced with SiC nano-particles have been conducted. The nanocomposites containing 5 Vol.%, 10 Vol.% and 15 Vol.% reinforcements, as well as pure magnesium, are studied by using the Design of Experiment (DOE) method. Cutting forces, surface morphology and surface roughness are characterized to understand the machinability of the four materials. Based on response surface methodology (RSM) design, experimental models and related contour plots have been developed to build a connection between different materials properties and cutting parameters. Those models can be used to predict the cutting force, the surface roughness, and then optimize the machining process.An analytical cutting force model has been developed to predict cutting forces of Mg-MMCs reinforced with nano-sized SiC particles in the micro-milling process. This model is different from previous ones by encompassing the behaviors of reinforcement nanoparticles in three cutting scenarios, i.e., shearing, ploughing and elastic recovery. By using the enhanced yield strength in the cutting force model, three major strengthening factors are incorporated, including load-bearing effect, enhanced dislocation density strengthening effect and Orowan strengthening effect. In this way, the particle size and volume fraction, as significant factors affecting the cutting forces, are explicitly considered. In order to validate the model, various cutting conditions using different size end mills (100 (&)#181;m and 1 mm dia.) have been conducted on Mg-MMCs with volume fraction from 0 (pure magnesium) to 15 Vol.%. The simulated cutting forces show a good agreement with the experimental data. The proposed model can predict the major force amplitude variations and force profile changes as functions of the nanoparticles' volume fraction. Next, a systematic evaluation of six ductile fracture models has been conducted to identify the most suitable fracture criterion for micro-scale cutting simulations. The evaluated fracture models include constant fracture strain, Johnson-Cook, Johnson-Cook coupling criterion, Wilkins, modified Cockcroft-Latham, and Bao-Wierzbicki fracture criterion. By means of a user material subroutine (VUMAT), these fracture models are implemented into a Finite Element (FE) orthogonal cutting model in ABAQUS/Explicit platform. The local parameters (stress, strain, fracture factor, velocity fields) and global variables (chip morphology, cutting forces, temperature, shear angle, and machined surface integrity) are evaluated. Results indicate that by coupling with the damage evolution, the capability of Johnson-Cook and Bao-Wierzbicki can be further extended to predict accurate chip morphology. Bao-Wierzbiki-based coupling model provides the best simulation results in this study. The micro-cutting performance of MMCs materials has also been studied by using FE modeling method. A 2-D FE micro-cutting model has been constructed. Firstly, homogenized material properties are employed to evaluate the effect of particles' volume fraction. Secondly, micro-structures of the two-phase material are modeled in FE cutting models. The effects of the existing micro-sized and nano-sized ceramic particles on micro-cutting performance are carefully evaluated in two case studies. Results show that by using the homogenized material properties based on Johnson-Cook plasticity and fracture model with damage evolution, the micro-cutting performance of nano-reinforced Mg-MMCs can be predicted. Crack generation for SiC particle reinforced MMCs is different from their homogeneous counterparts; the effect of micro-sized particles is different from the one of nano-sized particles.In summary, through this research, a better understanding of the unique cutting mechanism for particle reinforced heterogeneous materials has been obtained. The effect of reinforcements on micro-cutting performance is obtained, which will help material engineers tailor suitable material properties for special mechanical design, associated manufacturing method and application needs. Moreover, the proposed analytical and numerical models provide a guideline to optimize process parameters for preparing and micro-machining of heterogeneous MMCs materials. This will eventually facilitate the automation of MMCs' machining process and realize high-efficiency, high-quality, and low-cost manufacturing of composite materials.

This research not only examines how cultural values affect individual nutrition and maintenance of eating behaviors, it also addresses the extent to which accessibility impacts eating behaviors. Notably, the research endeavor uses the concept of dietary habitus as an underlying directive mechanism for study. This study finds that most students experience a reduction in their fruit and vegetable intake. Another finding suggests that international students eat healthier and are more structured in comparison to domestic students if they hybridize their dietary habitus. Research findings also suggest that most participants perceive food on campus to be both equally healthy and unhealthy, with limited accessibility to national cuisines and affordable healthy foods.

Show moreWhile the field of writing studies has studied digital writing as a response to multiple calls for more research on digital forms of writing, research on hashtags has yet to build bridges between different disciplines' approaches to studying the uses and effects of hashtags. This dissertation builds that bridge in its interdisciplinary approach to the study of hashtags by focusing on how hashtags can be fully appreciated at the intersection of the fields of information research, linguistics, rhetoric, ethics, writing studies, new media studies, and discourse studies. Hashtags are writing innovations that perform unique digital functions rhetorically while still hearkening back to functions of both print and oral rhetorical traditions. Hashtags function linguistically as indicators of semantic meaning; additionally, hashtags also perform the role of search queries on social media, retrieving texts that include the same hashtag. Information researchers refer to the relationship between a search query and its results using the term (")aboutness(") (Kehoe and Gee, 2011). By considering how hashtags have an aboutness, the humanities can call upon information research to better understand the digital aspects of the hashtag's search function. Especially when hashtags are used to organize discourse, aboutness has an effect on how a discourse community's agendas and goals are expressed, as well as framing what is relevant and irrelevant to the discourse. As digital activists increasingly use hashtags to organize and circulate the goals of their discourse communities, knowledge of ethical strategies for hashtag use will help to better preserve a relevant aboutness for their discourse while enabling them to better leverage their hashtag for circulation. In this dissertation, through a quantitative and qualitative analysis of the Twitter discourse that used #OrlandoStrong over the five-month period before the first anniversary of the Pulse shooting, I trace how the #OrlandoStrong discourse community used innovative rhetorical strategies to combat irrelevant content from ambiguating their discourse space. In Chapter One, I acknowledge the call from scholars to study digital tools and briefly describe the history of the Pulse shooting, reflecting on non-digital texts that employed #OrlandoStrong as memorials in the Orlando area. In Chapter Two, I focus on the literature surrounding hashtags, discourse, aboutness, intertextuality, hashtag activism, and informational compositions. In Chapter Three, I provide an overview of the stages of grounded theory methodology and the implications of critical discourse analysis before I detail how I approached the collection, coding, and analysis of the #OrlandoStrong Tweets I studied. The results of my study are reported in Chapter Four, offering examples of Tweets that were important to understanding how the discourse space became ambiguous through the use of hashtags. In Chapter Five, I reflect on ethical approaches to understanding the consequences of hashtag use, and then I offer an ethical recommendation for hashtag use by hashtag activists. I conclude Chapter Five with an example of a classroom activity that allows students to use hashtags to better understand the relationship between aboutness, (dis)ambiguation, discourse communities, and ethics. This classroom activity is provided with the hope that instructors from different disciplines will be able to provide ethical recommendations to future activists who may benefit from these rhetorical strategies.

Show moreCarbon nanotubes, graphene and nano sized core shell rubber particles have all been extensively researched for their capability to improve mechanical properties of thermoset resins. However, there has been a lack of research on their evaluation for energy absorption in high velocity impact scenarios, and the fundamental mechanics of their failure mechanisms during highly dynamic stress transfer through the matrix. This fundamental research is essential for laying the foundation for improvement in ballistic performance in composite armor. In hard armor applications, energy absorption is largely accomplished through delamination between plies of the composite laminate. This energy absorption is accomplished through two mechanisms. The first being the elongation of the fiber reinforcement contained in the resin matrix, and the second is the propagation of the crack in between the discreet fabric plies. This research aims to fundamentally study the energy absorption characteristics of various nano-particles as reinforcements in thermoset resin for high velocity impact applications. Multiple morphologies will be evaluated through use of platelet, tubular and spherical shaped nano-particles. Evaluations of the effect on stress transfer through the matrix due to the combination of nano sized and micro scale particles of milled fiber is conducted. Three different nano-particles are utilized, specifically, multi-walled carbon nanotubes, graphene, and core shell rubber particles. The difference in surface area, aspect ratio and molecular structure between the tube, platelet and spherical nano-particles causes energy absorption through different failure mechanisms. This changes the impact performance of composite panels enhanced with the nano-particle fillers. Composite panels made through the use of dispersing the various nano-particles in a non-contact planetary mixer, are evaluated through various dynamic and static testing, including unnotched cantilever beam impact, mixed mode fracture toughness, split-Hopkinson bar, and ballistic V50 testing.The unnotched cantilever beam testing showed that the addition of milled fiber degraded the impact resistance of the samples. Addition of graphene nano platelets unilaterally degraded impact resistance through the unnotched cantilever beam testing. 1.5% loading of MWCNT showed the greatest increase in impact resistance, with a 43% increase over baseline.Determining the critical load for mixed mode interlaminar shear testing can be difficult for composite panels that bend without breaking. An iterative technique of optimizing the coefficient of determination, R2, in linear regression is developed for objectively determining the point of non-linearity for critical load. This allows for a mathematical method of determination; thereby eliminating any subjective decision of choosing where the data becomes non-linear. The core shell rubber nano particles showed the greatest strain energy release rate with an exponential improvement over the baseline results.Synergistic effects between nano and micro sized particles in the resin matrix during transfer of the stress wave were created and evaluated. Loadings of 1% milled carbon fiber enhanced the V50 ballistic performance of both carbon nanotube and core shell rubber particles in the resin matrix. However, the addition of milled carbon fiber degrades the impact resistance of all nano-particle enhanced resin matrices. Therefore, benefits gained from the addition of micro-sized particles in combination with nano-sized particles, are only seen in high energy impact scenarios with micro second durations.Loadings of 1% core shell rubber particles and 1% milled carbon fiber have an improvement of 8% in V50 ballistic performance over the baseline epoxy sample for 44 mag single wad cutter gas check projectiles. Loadings of 1% multi-walled carbon nanotubes with 1% milled carbon fiber have an improvement of 7.3% in V50 ballistic performance over the baseline epoxy sample.The failure mechanism of the various nano-particle enhanced resin matrices during the ballistic event is discussed through the use of scanning electron microscope images and Raman spectroscopy of the panels after failure. The Raman spectroscopy data shows a Raman shift for the fibers that had an enhancement in the V50 performance through the use of nano-particles. The Raman band for Kevlar(&)#174; centered at 1,649 cm-1 stemming from the stretching of the C==O bond of the fiber shows to be more sensitive to the residual axial strain, while the Raman band centered at 1,611 cm-1 stemming from the C-C phenyl ring is minimally affected for the CSR enhanced panels due to the failure mechanism of the CSR particles during crack propagation.

The models investigate an interactive blend of textually-based linear-sequential approaches and visually-based spatial-simultaneous approaches. The models employ Gestalt-inspired figure-ground segregation models, along with other theoretical models, that demonstrate the dynamic capabilities of images as conceptual tools as well as alternate forms of text. The models encourage an interpretative style with active participants in open-ended, multi-sensory meaning-making processes. The models use the flexible tools of modern technology as approaches to meaning-making with art strategies used for research strategies as well as a means to appreciate reading and writing in the context of an increasingly visual environment.

Show moreLegends of the Fabricated Wild is a feature-length body of work of landscape films. Voice-Destroy, Self-Portrait: Impermanence and the titular Legends of the Fabricated Wild are the experimental films that comprise my body of work. Keep your Distance, a single-channel installation, is a supplemental piece.Legends of the Fabricated Wild frames the complex interaction between a filmmaker and the collective unconsciousness of the natural environment, a theory outlined by Carl Jung, considering the implications and discoveries along the way. Subtle movement and precise compositions provide a transcendental perspective on the natural Florida landscape. Images of landscapes devoid of human figures are structured together in my work to meditate on the environment and the way humanity has shaped the landscape. Super 8mm and 16mm analog film frames expansive landscapes in a square image and challenges modern cinematic representations by applying the texture of celluloid. High definition digital video contrasts analog film. I foreground artificiality and the ways humanity has utilized the landscape through this medium.While searching for places to document (")pure(") or untouched landscapes, I discovered that modern landscapes are always influenced by the exchange between humanity and the natural environment. I wanted to foreground my own interaction with the natural Florida environment and challenge my interests and dominant ways of viewing landscapes. Through the assembly of a cinematic essay of landscape images with subtle motion, I foster an appreciation for the natural environment in an age of hyper-activity and exploitation of the landscape.

Show moreDeveloping and demonstrating English proficiency is a critical skill for non-native English speakers (NNESs) who wish to study in American universities. Unlike their native English speaker (NES) counterparts, NNES students who apply for university admission are required to demonstrate their proficiency in English via tests, such as the Test of English as a Foreign Language (TOEFL), that measure an NNES's ability to understand, speak, read, and write English. Although the number of students who have attained those minimum scores is large, there is a large population of adult NNESs enrolled in intensive English programs (IEPs) that are designed to help them improve their proficiency in English and again admission into mainstream university courses. Given that many university instructors require the submission of written work that demonstrates students' understanding of course content, perhaps the most important academic skill developed in IEPs is writing. Furthermore, the lack of attention given to addressing grammatical errors at the tertiary level highlights IEP instructors' need for effective and efficient methods of addressing grammatical errors in NNES writing.The present quantitative study used two experimental designs, a pretest-posttest design and a posttest-only design with proxy pretest (Campbell (&) Stanley, 1963), to investigate the efficacy of two types of indirect corrective feedback (CF) for improving adult, IEP-enrolled, intermediate level NNES writers' (participants) grammatical accuracy in academic papers. Grammatical accuracy for this study was measured by counting the number of errors participants committed when using English definite and indefinite articles in academic papers. The independent variable for this study was the type of CF participants were randomly selected to receive (-) either screencast corrective feedback (SCF) or written corrective feedback (WCF). The dependent variable, which measured the effect of the CF given, was the number of errors participants made with English definite and indefinite articles on three compositions completed to satisfy the requirements of their IEP writing class. The results of the current research demonstrated that participants made similar gains in grammatical accuracy when using CF to revise descriptive compositions. These results are in keeping with the results of previous studies that showed the usefulness of CF for improving grammatical accuracy on revised compositions (Bitchener, 2008, Bitchener (&) Knoch, 2008, 2009a, 2009b, 2010a). However, the improvement observed on the revised descriptive compositions did not transfer to new classification essays, regardless of the type of CF participants received. Participants' lack of grammatical accuracy on new compositions of a different genre effectively illustrated the difficulty English articles pose for NNESs when writing and the need for multiple exposures to CF and writing practice to develop NNESs' ability to consistently use English articles accurately.The main implication of the present study lies in the recommendation of the provision of CF to NNES students and systematic instruction about how to use CF received in order to allow NNESs to become more self-sufficient learners and writers of English.

Show moreAerospace research for next-generation travel increasingly focuses on the use of advanced composites to reduce weight and cost while retaining strength. One subset of materials with great potential is based on the combination of resin matrix and glass-fiber reinforcement. This research explores the application of a candidate nanopaper coating with a given composite. Prior research applied a set of given heat fluxes to the top surface of the composite for a set of given periods of time, and subsequently performed a 3-point flexural test to determine the elastic modulus for both the coated and uncoated composite for all of the combinations of heat flux and time. A finite element (FE) model is developed using the ANSYS general purpose finite element analysis (FEA) software that models the degradation in strength/stiffness properties based on heating condition and with the goal of predicting cracking using the element death feature in ANSYS. This thesis describes the prior research suggesting both the need for and novelty of this model, and the procedures used to form the model. The loading conditions of the 3-point flexural test are replicated, and four measures of accuracy are developed based on the force versus displacement curve of the test and the FE model. It is envisioned that continuum-level models developed as a part of these research be applied for design of next-generation space components These measurements are used to verify the FE model, and this model is then employed to extrapolate beyond the context of experimental conditions.

Show moreA growing body of writing research suggests college students' and teachers' conceptualizations of writing play an important role in learning to write and making the transition from secondary to post-secondary academic composition. First-year college writers are not blank slates; rather, they bring many assumptions and beliefs about academic writing to the first-year writing classroom from exposure to a wide range of literate practices throughout their lives. Metaphor acts as a way for scholars to trace students' as well as their instructors' assumptions and beliefs about writing. In this study, I contend that metaphor is a pathway to meta-cognitive awareness, mindfulness, and reflection. This multi-method descriptive study applies metaphor analysis to a corpus of more than a dozen first-year composition students' end-of-semester writing portfolios; the study also employs an auto-ethnographic approach to examining this author's texts composed as a graduate student and novice teacher. In several cases writing students in this study appeared to reconfigure their metaphors for writing and subsequently reconsider their assumptions about writing. My literature review and analysis suggests that metaphor remains an underutilized inventive and reflective strategy in composition pedagogy. Based on these results, I suggest that instructors consider how metaphoric competence might offer writers and writing instructors an alternate means for operationalizing key habits of mind such as meta-cognitive awareness, reflection, openness to learning, and creativity as recommended in the Framework for Success in Post-Secondary Writing. Ultimately, I argue that writers and teachers might benefit from adopting a more flexible attitude towards metaphor. As a rhetorical trope, metaphors are contextual and, thus, writers need to learn to mix, discard, create, and obscure metaphors as required by the situation.

Show moreGraphite is an allotrope of carbon made up of atomically thin sheets, each covalently bound together, forming a ?-conjugated network. An individual layer, called graphene, has extraordinary electrical, thermal and physical properties that provide the opportunity for innovating new functional composites. Graphene can be produced directly on a metallic substrate by chemical vapor deposition or by chemical oxidation of graphite, forming a stable aqueous suspension of graphene oxide (GO), which allows for convenient solution processing techniques. For the latter, after thermal or chemical reduction, much of the properties of the starting graphene re-emerge due to the reestablishment of ?-conjugation. The ?-conjugated basal plane of graphene has been shown to influence the crystallization of ?-conjugated polymers, providing thermodynamically strong nucleation sites through the relatively strong ?-? interactions. These polymers can homocrystallize into 1-D filaments, but when nucleated from graphene, the orientation and geometry can be controlled producing hierarchical structures containing an electrical conductor decorated with wires of semi-conducting polymer. The resulting structures and crystallization kinetics of the conjugated polymer, poly(3-hexylthiophene-2,5-diyl) (P3HT) nucleated by graphene was studied. Further, field-effect transistors were developed using graphene as both the electrodes and the polymer crystallization surface to directly grow P3HT nanowires as the active material. This direct crystallization technique lead to higher charge mobility and higher on-off ratios, and this result was interpreted in terms of the morphology and polymer-graphene interface.Besides these thin-film technologies, neat GO suspensions can be lyophilized to produce monolithic, free-standing aerogels and then reduced to produce an electrically conductive porous material with a surface area greater than 1000 m2/g. The present research focuses on functionalizing the aerogel surfaces with metal nanoparticles to increase electrical conductivity and to impart functionality. Functionalization was carried out by adding a metal salt as a precursor and a chelating agent to inhibit GO flocculation. The GO and metal salt were simultaneously reduced to form rGO aerogels homogeneously loaded with metal nanoparticles. The size and distribution of these nanoparticles was controlled by concentration and chelating agent identity and abundance. Optimum aerogel formulations were used as a functioning and reversible conductometric hydrogen gas sensor and as an anode in an asymmetric supercapacitor with excellent properties.
