Yearbooks As A Genre: A Case Study, Melissa Caudill Dec 2007

Yearbooks As A Genre: A Case Study, Melissa Caudill

All Theses

ABSTRACT
In the United States, high school and college yearbooks are extraordinarily well known as a genre, yet they are largely unstudied. Yearbooks preserve images, stories, and facts from each year for one specific group of people, linked by age and geographic community. Yearbook production is a significant commercial enterprise, yet it involves novice writers, editors, and designers. Blending elements of craft, tradition, business, and media, yearbooks as a distinctive genre bear closer rhetorical study and application of professional communication theories.
This historical case study of production practices for a particular college yearbook positions yearbooks rhetorically as texts and sites …

Spitzer Irs Observations Of Seyfert 1.8 And 1.9 Galaxies: A Comparison With Seyfert 1 And Seyfert 2, R. P. Deo, D. M. Crenshaw, S. B. Kraemer, M. Dietrich, Moshe Elitzur, H. Teplitz, T. J. Turner Dec 2007

Spitzer Irs Observations Of Seyfert 1.8 And 1.9 Galaxies: A Comparison With Seyfert 1 And Seyfert 2, R. P. Deo, D. M. Crenshaw, S. B. Kraemer, M. Dietrich, Moshe Elitzur, H. Teplitz, T. J. Turner

Physics and Astronomy Faculty Publications

We present Spitzer mid-infrared spectra of 12 Seyfert 1.8 and 1.9 galaxies over the 5-38 μm region. We compare the spectral characteristics of this sample to those of 58 Seyfert 1 and 2 galaxies from the Spitzer archives. An analysis of the spectral shapes, the silicate 10 μm feature and the emission-line fluxes have enabled us to characterize the mid-IR properties of Seyfert 1.8/1.9s. We find that the EWs of the 10 μm silicate feature are generally weak in all Seyfert galaxies, as previously reported by several studies. The few Seyfert galaxies in this sample that show …


Provisioning And Prey Quality In Brown Pelicans (Pelecanus Occidentalis) In Charleston Harbor, South Carolina, Elena Sachs Dec 2007

Provisioning And Prey Quality In Brown Pelicans (Pelecanus Occidentalis) In Charleston Harbor, South Carolina, Elena Sachs

All Theses

I examined parent and nestling behavior during early chick rearing in Brown Pelicans (Pelecanus occidentalis) nesting at a colony in Charleston Harbor, South Carolina during the 2006 breeding season. There were significant differences in the frequency of feeding, attendance, and chick aggression according to chick age, although the pattern differed among behaviors. The rate of adult feeding, chick feeding and adult attendance all decreased with chick age while chick aggressive behavior peaked when chicks were ca. 21 d post-hatch. I found that nests with at least one juvenile parent had a lower average clutch size, hatch rate, and number of …


Mixed Convective Heat Transfer And Evaporation At The Air-Water Interface, Prasad Gokhale Dec 2007

Mixed Convective Heat Transfer And Evaporation At The Air-Water Interface, Prasad Gokhale

All Theses

Functional forms for mixed convective heat transfer and evaporation from an air-water interface were obtained. To obtain these functions, heat transfer and evaporation rates from the air-water interface of an evaporating body of water were quantified in a wind/water tunnel in the presence of an oleyl alcohol monolayer on the water surface. The Nusselt (Nu) and Sherwood (Sh) numbers, parameterizing the dimensionless heat and mass transfer respectively, for transport from the water bulk to air were expressed as functions of the air side Rayleigh (Ra) and Reynolds (Re) numbers. The Nu and Sh were calculated for a range of Ra …

Learning Languages From Positive Data And A Limited Number Of Short Counterexamples, Sanjay Jain, Efim Kinber Dec 2007

Learning Languages From Positive Data And A Limited Number Of Short Counterexamples, Sanjay Jain, Efim Kinber

School of Computer Science & Engineering Faculty Publications

We consider two variants of a model for learning languages in the limit from positive data and a limited number of short negative counterexamples (counterexamples are considered to be short if they are smaller than the largest element of input seen so far). Negative counterexamples to a conjecture are examples which belong to the conjectured language but do not belong to the input language. Within this framework, we explore how/when learners using n short (arbitrary) negative counterexamples can be simulated (or simulate) using least short counterexamples or just ‘no’ answers from a teacher. We also study how a limited number …


Sediment Transport Upstream Of Orifices, David Powell Dec 2007

Sediment Transport Upstream Of Orifices, David Powell

All Dissertations

Sediment transport upstream of orifices has not been studied outside the realm of the restoration of reservoir storage capacity. This experimental study used a large basin with a circular orifice outlet and a movable sand bed leveled with the invert of the orifice. Three sizes of non-cohesive, uniform sand were used with d50 values of 0.29mm, 0.72mm, and 0.89mm. Bed profiles at equilibrium scour conditions were measured for three different head levels for each sediment size. The maximum scour depth, length, and scour width were related to the particle size and the available head. The longitudinal and lateral extents …


Hybrid Image/Model Based Gaze-Contingent Rendering, Hunter Murphy Dec 2007

Hybrid Image/Model Based Gaze-Contingent Rendering, Hunter Murphy

All Dissertations

A non-isotropic hybrid image/model based gaze-contingent rendering technique utilizing ray casting on a GPU is discussed. Empirical evidence derived from human subject experiments indicates an inverse relationship between a peripherally degraded scene's high-resolution inset size and mean search time, a trend consistent with existing image-based and model-based techniques. In addition, the data suggest that maintaining a target's silhouette edges decreases search times when compared to targets with degraded edges. Benefits of the hybrid technique include simplicity of design and parallelizability, both conducive to GPU implementation.


Enhancing The Ability Of Panicum Virgatum To Survive Flooding And Its Effects On Soil Activity When Used For Lakeshore Stabilization, Lee Edwards Dec 2007

Enhancing The Ability Of Panicum Virgatum To Survive Flooding And Its Effects On Soil Activity When Used For Lakeshore Stabilization, Lee Edwards

All Dissertations

Reservoirs in upstate South Carolina are subject to erosion and vegetation has been placed to help stabilize banks, but soils are nutrient-poor and have high bulk densities. Panicum virgatum L. (switchgrass) has been planted in several sites, and it is hypothesized that over time, changes in microbial activity and soil quality will occur in response to the planting. As vegetated sites aged, acid phosphomonoesterase, nitrate reductase, and dehydrogenase activity increased. Low values of nitrogen fixation and substrate-induced respiration were measured at all sites with no statistical differences between sites. Fatty acids indicative of Gram negative bacteria were found in vegetated …


The Consumer Choice Of E-Channels As A Purchasing Avenue: An Investigation Of The Communicative Aspects Of Information Qualtiy , Jaejoo Lim Dec 2007

The Consumer Choice Of E-Channels As A Purchasing Avenue: An Investigation Of The Communicative Aspects Of Information Qualtiy , Jaejoo Lim

All Dissertations

A conspicuous paradox is evident in the statistics concerning purchases over the internet. While a majority of the US population uses the internet to seek product information for purchasing decisions, less than two percent of actual retail sales occur on the Internet. To explain this small ratio of e-channel choice for purchase, a comprehensive model that extends DeLone and McLean's (2004) e-commerce success model was developed. The model centers on the importance of perceived information quality and its relationship to e-channel choice as a purchasing channel. Using the overarching theoretical frame of motivation, two questions were examined: (a) what influences …


Examining The Effects Of Fatigue On Decision-Making In Nursing: A Policy-Capturing Approach, Laura Mcclelland Dec 2007

Examining The Effects Of Fatigue On Decision-Making In Nursing: A Policy-Capturing Approach, Laura Mcclelland

All Dissertations

Some previous research has focused on better understanding factors that influence nurses' decision-making; however, previous research has not used policy-capturing as a methodology to examine the impact of fatigue on registered nurses' decision-making. The purpose of the current study was to examine whether the fatigue of working a 12-hour day shift influenced a sample of registered nurses' decision-making. Participants consisted of 69 registered nurses working a 12-hour day shift from 7 AM to 7 PM at a large southeastern hospital. The participants completed a general questionnaire and a policy-capturing questionnaire at the beginning and at the end of a 12-hour …


Characterization Of The Anti-Angiogenic Properties Of Kdr-Ig4-7 And Its Variants As Potential Anti-Cancer Therapeutics, Jang Pyo Park Dec 2007

Characterization Of The Anti-Angiogenic Properties Of Kdr-Ig4-7 And Its Variants As Potential Anti-Cancer Therapeutics, Jang Pyo Park

All Dissertations

Beginning with the development of an embryo and throughout one's adult life angiogenesis plays an essential role for organ growth and repair. The balancing of pro-angiogenic factors to anti-angiogenic factors is what regulates the process of angiogenesis. When this balance is disrupted in one direction or the other, numerous disorders can occur including ocular and inflammatory diseases and, in particular, tumor growth and metastasis. Therefore, inhibition of angiogenesis has become an effective therapy for arresting the growth of tumors.
A key regulator of angiogenesis involves vascular endothelial growth factor (VEGF) and its receptor, VEGFR-2 (KDR). The binding of VEGF to …


Phylogeny And Classification Of Hydropsychidae Subfamilies And Genera Of The World (Insecta: Trichoptera), Christy Geraci Dec 2007

Phylogeny And Classification Of Hydropsychidae Subfamilies And Genera Of The World (Insecta: Trichoptera), Christy Geraci

All Dissertations

The family Hydropsychidae is nearly ubiquitous in streams and rivers, with over 1600 described species worldwide. Hydropsychidae is ecologically important and its larvae play key roles as indicators of water quality. Conflicting morphological characters have obscured the evolutionary history of the subfamilies, and the wide diversity of phallic morphology among Hydropsyche sensu lato species has created unstable classification systems that have been disputed among authors. My research used five nuclear ribosomal and mitochondrial COI fragments to infer a molecular phylogeny for Hydropsychidae subfamilies and genera, focusing particularly on the Hydropsychinae and the Hydropsyche sensu lato lineage. The monophyly of four …

Lmx Theory Related To Administrator And Educator Perceptions, Theodore Mauro

All Dissertations

Retaining qualified special educators has been a persistent challenge for school districts nationwide. Given that research findings have identified the presence of a supportive principal as a vital factor in the retention of special educators, it is imperative that this pressing issue be further examined. The purpose of this study was to examine differences in the perceptions of principals (ADM), general educators (GET), and special educators (SET) across nine schools in a South Carolina school district regarding what constitutes a supportive and collaborative school environment. Specifically, (a) do administrators, educators and special educators have different perceptions of the collaborative nature …

Development Of Fullerene Based Sturctures For Photovoltaic And Electronic Applications, Amit Palkar Dec 2007

Development Of Fullerene Based Sturctures For Photovoltaic And Electronic Applications, Amit Palkar

All Dissertations

Solar energy can be envisioned as a long term alternative to rapidly depleting fossil fuels. The energy from the sun can be harnessed by constructing donor-acceptor (D-A) type devices where the incident photon induces the transfer of an electron from the donor to the acceptor. If recombination is prevented, this electron can then be channeled through an external circuit, thus leading to the generation of photocurrent. Porphyrins, which are the naturally occurring pigments in photosynthesis, have been widely established as donors while fullerenes, such as C60 and C70 , due to their unique electron accepting properties, have been …

Ddasaccident548, Hd-Aid Dec 2007

Ddasaccident548, Hd-Aid

Global CWD Repository

The deminer was investigating the signal and excavating by sitting/squatting position and his prodder/bayonet detonated the PMN mine. The evidence on site shows that the excavation of the signal started from the first mark, and not 30cm back from the indication. The bayonet directly touched the mine causing a detonation. This indicates he was not conducting operations with the correct procedure.

When West Meets East: Communicative Language Teaching In China, Rong Li

Theses and Dissertations

With radical social change and educational reform taking place in China since 1976, the English teaching system there has been changing accordingly. The Chinese Traditional Method (CTM) is giving way to the Western Communicative Language Teaching (CLT) approach. This research is a study of both Chinese and expatriate English teachers who are involved in classrooms and affected by reforms. The goal of this research study is to identify the extent to which Chinese and expatriate English teachers use CLT in China, to discover the possible factors that prevent them from using CLT and to explore an English teaching method that …


A Context Aware Content Based Federated Access Control System For Healthcare Domain, Haseeb Amjad Dec 2007

A Context Aware Content Based Federated Access Control System For Healthcare Domain, Haseeb Amjad

Department of Electrical and Computer Engineering Masters Theses

Legislation to create electronic healthcare records and provide electronic healthcare services requires the same level of privacy and disclosure regulations as are applicable to the current practices for paper based patient health records. Most of work in this area has been organization-oriented that deals with exchange of information among healthcare organizations (such as referrals). However, the requirements for ensuring security and privacy of information for online access and sharing of health records in a federated healthcare environment have not been adequately addressed. To address this problem, we have developed a context-aware content-based access control policy specification framework, known as Generalized …

Structure Formation Inside Triaxial Dark Matter Halos: Galactic Disks, Bulges, And Bars, Clayton Heller, Isaac Shlosman, Evangelie Athanassoula Dec 2007

Structure Formation Inside Triaxial Dark Matter Halos: Galactic Disks, Bulges, And Bars, Clayton Heller, Isaac Shlosman, Evangelie Athanassoula

Physics & Astronomy: Faculty Publications

We investigate formation and evolution of galactic disks immersed in assembling live DM halos. Models have been evolved from cosmological initial conditions and represent the collapse of an isolated density perturbation. The baryons include gas participating in star formation (SF) and stars with the energy feedback onto the ISM. We find that (1) the triaxial halo figure tumbling is insignificant and the angular momentum (J) is channeled into the internal circulation, while the baryonic collapse is stopped by the centrifugal barrier; (2) density response of the (disk) baryons is out of phase with DM, thus washing out the …

Porcine Intestinal Epithelial Cell Lines As A New In Vitro Model For Studying Adherence And Pathogenesis Of Enterotoxigenic Escherichia Coli, Seung Y. Koh, Sajan George, Volker Brozel, Rodney A. Moxley, David H. Francis, Radhey Kaushik

School of Veterinary and Biomedical Sciences: Faculty Publications

Enterotoxigenic Escherichia coli (ETEC) infections result in large economic losses in the swine industry worldwide. The organism causes diarrhea by adhering to and colonizing enterocytes in the small intestines. While much progress has been made in understanding the pathogenesis of ETEC, no homologous intestinal epithelial cultures suitable for studying porcine ETEC pathogenesis have been described prior to this report. In the current study, we investigated the adherence of various porcine ETEC strains to two porcine (IPEC-1 and IPEC-J2) and one human (INT-407) small intestinal epithelial cell lines. Each cell line was assessed for its ability to support the adherence of …
