Electronic Theses and Dissertations Archive

Through two studies, this research is some of the first to-date to test how the use of social networking websites affects worker well-being and career success. In a period of less than a decade, online social media has quickly redefined many core aspects of human relationships. In 2012, the website, Facebook, reported that one in eight people worldwide used the site weekly. Given such prevalence, this research has far reaching implications for U.S. workers and organizations. The first study (N = 238) used structural equation modeling to examine the effect of site use with coworkers on well-being through increases in …

Flood Inundation Mapping Using Hec-Ras And Gis For Shelby County, Tennessee, Farid Javadnejad

Electronic Theses and Dissertations Archive

Flood zones with 1% and 0.02% of annual flooding chance are projected in the ‎Federal Emergency Management Agency’s (FEMA) digital flood insurance rate maps ‎‎(DFIRMs) and are suited for identifying flood risk at the largest impacts. However, less ‎severe floods, which are not mapped in DFIRMs, still cause significant damage and ‎occur on a more frequent basis. This article employs an easy-to-setup GIS-based ‎solution for rapid inundation mapping of small flood events. The linear interpolation ‎technique (LITE Flood) is developed to rescale the hydraulic behavior inherent with a ‎larger flood event without performing additional hydraulic simulations. The approach is ‎evaluated …

The incorporation of ArcGIS 10 is critical to the success of this project because it provides a means of quick visual analysis of intersection related crash data within the city. This provides Germantown officials with a …

Passivization Of Em Peec Solutions In The Frequency And Time Domain, Albert E. Ruehli, Giulio Antonini, Lijun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

The stability issues for time domain integral equations is well known and it has been investigated for a long time. In this paper, we pursue an approach for the stabilization and even passivization of the electromagnetic solutions in the time and frequency domain using the PEEC circuit techniques. We aim to enhance the passivity by adding more passivization to the EM solution rather than using a post-processing technique which have to be used in the EM solver is not available. © 2013 IEEE.

Fast And Efficient Low-Frequency Algorithms For Multiscale Structure Modeling, Sheng Sun, Zu Hui Ma, Qin S. Liu, Zhi Guo Qian, Lijun Jiang, Weng Cho Chew

Electrical and Computer Engineering Faculty Research & Creative Works

This paper reviews our recently developed fast and efficient algorithms for multiscale structure modeling. Low-frequency electromagnetic analysis becomes indispensable for multi-scale structures because of the involved minute length-scale compared to wavelength and mid length-scale on the order of wavelength or larger, where wave physics meets circuit physics. We are currently investigating stable low-frequency solutions in solving integral equations without the need for loop-tree decomposition, including the augmented EFIE, equivalence principle based algorithms, and perturbation-based Calderon multiplicative preconditioning methods. © 2013 IEEE.

Surficial Geologic Map Of Kings Canyon: Implications For Relatively Slow Stream Incision Rates, Andrew Farris

Natural Resources Management and Environmental Sciences

Most of the Kings River in the Sierra Nevada Mountains of California has responded to regional uplift with rapid incision, creating the deepest canyon in the United States. However, Kings Canyon near Cedar Grove is still a mountainous relict landscape with little evidence of fluvial incision. Mapping took place in the Cedar Grove area of Kings Canyon to assess factors and/or processes causing relatively low stream incision rates in the region during Holocene time. A surficial geologic map was created in the field, along with visual observations of the South Fork of the Kings River and characterization of geologic map …

The Leonard Bernstein Artful Learning Model: A Case Study Of An Elementary School, David S. Brothman

Other Dissertations

Case study methodology was used to explore and better understand how the Leonard Bernstein Artful Learning comprehensive school reform model impacted a high performing suburban elementary school outside Chicago, Illinois. The school adopted the model not because it was doing poorly academically, but rather as a vehicle to institute a comprehensive arts-based curriculum school wide. Focusing primarily on teachers’ perceptions of how the model affected teaching and learning in their classroom, the study also uncovered how the school, families, the community, and district leadership responded to and supported Artful Learning over a five year period since its inception. The study …

Fabrication And In Vivo Thrombogenecity Testing Of Nitric Oxide Generating Artificial Lungs, Kagya Amoako, Patrick Montoya, Terry C. Major, Ahmed B. Suhaib, Hitesh Handa, David O. Brant, Mark E. Meyerhoff, Robert H. Bartlett, Keith E. Cook

Mechanical and Industrial Engineering Faculty Publications

Hollow fiber artificial lungs are increasingly being used for long-term applications. However, clot formation limits their use to 1–2 weeks. This study investigated the effect of nitric oxide generating (NOgen) hollow fibers on artificial lung thrombogenicity. Silicone hollow fibers were fabricated to incorporate 50 nm copper particles as a catalyst for NO generation from the blood. Fibers with and without (control) these particles were incorporated into artificial lungs with a 0.1 m2 surface area and inserted in circuits coated tip-to-tip with the NOgen material. Circuits (N = 5/each) were attached to rabbits in a pumpless, arterio-venous configuration and run for …

Development And Application Of A Biorobotic Simulation Of Stance Phase Gait To Study Foot And Ankle Kinematics, Kelly N. Salb

Theses and Dissertations (ETD)

Ankle instantaneous axis of rotation (IAR) measurements represent a more complete parameter for characterizing joint motion. However, few studies have implemented this measurement to study normal, injured, or pathological foot-ankle biomechanics. Additionally, while load is suggested to play a major role in ankle biomechanics, including influences on articular surfaces, bony motion, and formation of the arches, studies concerning the effects of joint loading are limited.

A novel testing protocol was developed to simulate in vivo mechanics of the foot-ankle complex during early stance phase gait in a human cadaveric model. Two studies were conducted. The first study was to assess …

Discipleship As A Catalyst For Personal Transformation In The Christian Faith, Vanessa Marie Seifert

Theses & Dissertations

Some Christian churches approach the majority of their faith expression with a 'go to the community' dynamic, while other churches focus primarily on attracting the community to 'come to them.' The problem is that there is a growing population of religiously unaffiliated people in the United States for whom traditional forms of faith expression are not meaningful. A new way of thinking about communal faith expression is needed if the church seeks to reach people who are spiritually curious but not interested in the attractional church model. The journey towards organizational change, even for churches, often begins with a commitment …

Cultural Commons In Non-Traditional And Traditional Secondary Education: A Media Ecology Approach, Anthony Baerga

Theses & Dissertations

Based on the theory of media ecology, this study explores the cultural commons between traditional and non-traditional education in secondary schools. Postman's study of media ecology presents the notion that media technology plays an integral part in society and cannot be overlooked; more so, technologies should be used as an ecological learning tool to balance education systems (Postman 1992). Within the past four years, U.S. education witnessed over 100,000 students leave the traditional classroom to embark on a virtual education journey (Miron, Horvitz, and Gulosino, 2013). The purpose of this exploratory study is to examine how teachers create a media …
