Characterization Of Electrodeposited Copper Foil Surface Roughness For Accurate Conductor Power Loss Modeling, Michael B. Griesi Dec 2014

Characterization Of Electrodeposited Copper Foil Surface Roughness For Accurate Conductor Power Loss Modeling, Michael B. Griesi

Theses and Dissertations

As computer data rates have increased, designers observed that the standard models for estimating the impact of copper foil surface roughness on conductor loss are limited to a few GHz. The more recent snowball model (a “snowball” estimation of the Huray Model) has demonstrated improved conductor loss predictions up to 50 GHz by estimating the necessary parameters using reasonable assumptions about the geometric surface features of electrodeposited copper foil. Since then, the Huray Model has been incorporated into commercial electromagnetic field simulators. However, a standard method of characterizing the electrodeposited copper foil used in high-speed circuits to directly implement the …

Analysis Of Hurricane Preparedness Levels And Evacuation Intent For South Carolina Coastal Residents, Wesley Chad Seigler Dec 2014

Analysis Of Hurricane Preparedness Levels And Evacuation Intent For South Carolina Coastal Residents, Wesley Chad Seigler

Theses and Dissertations

Many communities across the nation, especially those in coastal areas, are experiencing extensive growth and expansion. This growth and the associated need for additional infrastructure, goods and services, and basic human needs often place people and the things they value in harm’s way due to the threat of a natural disaster. In order to properly prepare and mitigate disaster impacts, individuals and communities must view disasters as events that will likely occur at least once during their lifetime rather than simply outside possibilities. Residents of coastal communities must prepare for potential impacts from hurricanes and resulting storm surges and must …

A Phenomenological Study Of Student Engagement In United States History Classrooms, Emily Louvette Manigault Dec 2014

A Phenomenological Study Of Student Engagement In United States History Classrooms, Emily Louvette Manigault

Theses and Dissertations

The purpose of this phenomenological study is to explore the relationship between student engagement and the perception of academic achievement (learning) by teachers and students in an urban high school social studies course. Over the past several years, educational leaders and researchers have tried to find a cause for a number of issues in public education, including low academic achievement, increasing student drop-out rates and the decline of positive perceptions of schools in general. As a result, there has been increasing research done on the level of engagement that students experience during their schooling. Much of the research has focused …

Measurement Of Polarization Observables PZ, PSZ, And PCZ In Double-Pion Photoproduction Off The Proton, Yuqing Mao Dec 2014

Measurement Of Polarization Observables PZ, PSZ, And PCZ In Double-Pion Photoproduction Off The Proton, Yuqing Mao

Theses and Dissertations

Meson production from excited nucleons is important in the study of baryon resonances and pion photoproduction is attracting much attention. To date a rather large amount of unpolarized cross-section measurements have been reported for both single- and double-pion photoproduction. However, polarization observables provide complementary information as they probe different combinations of transition amplitudes. The database for polarization observables remains quite sparse. Double-pion photoproduction have been studied in Hall B at Jefferson Lab with linearly polarized tagged photon beams incident on longitudinally polarized protons. The experiment covered center-of-mass energies between 1.4 GeV and 2.3 GeV. The target was a FROzen Spin …

Toward A Theory Of Safe Passage: Agentic Practices Of Women Writers Who Teach, Lillian Gordon Reeves Dec 2014

Toward A Theory Of Safe Passage: Agentic Practices Of Women Writers Who Teach, Lillian Gordon Reeves

Theses and Dissertations

Past studies show that narrative is an effective tool for guiding teachers to develop teacher identity, to recognize their practical knowledge, and to engage in teacher transformation, especially during initial teacher training and the early years of their career. Consequently, other researchers have identified how narrative studies inform what we know about teachers’ identities, their practical knowledge, and their transformations during initial training and early career teaching. However, we do not know how narrative functions in the experiences of teachers beyond initial teacher training and early career teaching. This study intends to fill this gap in the research. In this …

Determinants Of Cross-Country Differences In The Equity Risk Premium: A Cross-Sectional Analysis, William John Arant Dec 2014

Determinants Of Cross-Country Differences In The Equity Risk Premium: A Cross-Sectional Analysis, William John Arant

Theses and Dissertations

The equity risk premium (ERP) is a critical factor in financial decision-making and allocating capital for the future. The ERP can indicate the aggregate risk in an economy and thereby the price agents attach to that risk. Understanding the factors that determine ERPs across countries is important for understanding investors’ actions in a globalized environment. This study will focus on long-run measures of the ERP across countries while applying four common measures. Variations in the size of the ERP across countries and across measures will be examined. Then, country-specific determinants of the long-run ERP will be investigated. These determinants include …

Essays On Battle Clusters In Internal Armed Conflicts And Insurgencies: Concept, Causes And Consequences, Chifeng Liu Dec 2014

Essays On Battle Clusters In Internal Armed Conflicts And Insurgencies: Concept, Causes And Consequences, Chifeng Liu

Theses and Dissertations

With the purpose to re-conceptualize the intensity of internal armed conflicts, I argue that the characteristics such as location, scale and duration of “major battlefields,” i.e. the spatio-temporal clusters of combat events are important in the evaluation of impact of modern civil wars and insurgencies. I start with elaborating and constructing a new concept of conflict magnitude with battle clusters using up-to-date geo-referenced data and spatial statistic methods. In the second article, I first explain the location and duration of major battlefields. The findings indicate that an area with multiple non-state armed groups (NSAGs) is more likely to become main …

Living On The Moon: Women, Home Making, And The House After World War Ii In Shirley Jackson’S We Have Always Lived In The Castle, Leslie Dennis

Theses and Dissertations

In my thesis, I concentrate on Shirley Jackson, her novel We Have Always Lived in the Castle, and women’s place in post-World War II American society. To start, I introduce Jackson and her role in literary history, the housewife writer in the 1950s and 60s, and magazine culture. Then I move to a historical perspective of the 1950s and propaganda during the atomic war era. I focus my attention on how government literature worked to contain women in the home and control sexuality and gender roles. Following my discussion of domesticity, I concentrate on the history of the Gothic novel …

Task-Specific Human Capital Accumulation And Wage Outcomes Among Young Men: An Empirical Analysis, Morgan Holland Dec 2014

Task-Specific Human Capital Accumulation And Wage Outcomes Among Young Men: An Empirical Analysis, Morgan Holland

Theses and Dissertations

Existing literature suggests that investment in different kinds of task-specific human capital may have significant effects on wage outcomes and overall economic wellbeing of individuals. To examine this claim, the accumulation of task-specific human capital in young male workers with no college education and its effects on wages is measured. Using National Longitudinal Survey of Youth panel data merged with six task-specific human capital measures derived from the Dictionary of Occupational Titles task contents data, fixed effects regression was utilized to measure how workers’ taskspecific human capital develops over time. This process shows that among the task measures used, accumulation …

The Poetic Works Of Charlotte Smith: Philosophy, Sympathy, And Forging Community, Jessica Danielle Castillo Dec 2014

The Poetic Works Of Charlotte Smith: Philosophy, Sympathy, And Forging Community, Jessica Danielle Castillo

Theses and Dissertations

This work will focus on Charlotte Smith’s poetic works and how, over the course of her entire poetic career (the late eighteenth century/early nineteenth century), she exhibits a concrete sense of a poetic ethos regarding sympathy in her writing. I seek to account for the overwhelming focus on suffering subjects by illuminating her view of the relation between poetry and sympathy for others. I will also place her within a history of writers and philosophers who examined the epistemological and practical nature of feeling, sympathy, and emotional connection among human beings. Smith feels that poetry renders suffering visible to others, …

An Engineering Approach For The Design Of Archaeological Reburial Systems, Angel Ari Perez Mejia Dec 2014

An Engineering Approach For The Design Of Archaeological Reburial Systems, Angel Ari Perez Mejia

Theses and Dissertations

Archaeological sites are a non-renewable resource which is often our only link to the past. However, sites are under constant threat of destruction due to construction activities. Civil engineers and archaeologists must the work together to ensure both the continued survival of archaeological sites while allowing for development to continue. Reburial systems, when properly designed and constructed, allow for the protection of archaeological sites while allowing the continued use of the land. However, because reburial as an intentional conservation technique is relatively modern, practice is fragmented and there are no universally accepted guidelines. Current reburial system design relies on prescriptive …

Piezotransistive Iii-V Nitride Microcantilever Based Mems/Nems Sensor For Photoacoustic Spectroscopy Of Chemicals, Abdul Hafiz Ibne Talukdar Dec 2014

Piezotransistive Iii-V Nitride Microcantilever Based Mems/Nems Sensor For Photoacoustic Spectroscopy Of Chemicals, Abdul Hafiz Ibne Talukdar

Theses and Dissertations

Microcantilevers are highly attractive as transducers for detecting chemicals, explosives, and biological molecules due to their high sensitivity, micro-scale dimensions, and low power consumption. Though optical transduction of the mechanical movement of the microcantilevers into an electrical signal is widely practiced, there is a continuous thrust to develop alternative transduction methods that are more conducive to the development of compact miniaturized sensors. Piezoelectric and piezoresistive transduction methods are two of the most popular ones that have been utilized to develop miniaturized sensor systems. Piezoelectric cantilevers, which are commonly made of PZT film, have demonstrated very high sensitivity; however, they suffer …

Grand Prix: A Trainer's Guide To Show Ring Success, Lauren Rebecca Allen

Theses and Dissertations

This is a memoir of my experiences as a horse lover and professional horse trainer, and the startling parallels I discovered in the Los Angeles equestrian and entertainment industries. Both worlds revolve around commodifying something that is rooted in beauty but somehow gets bruised in the process of spinning art into business. I found that my taste for romance and adventure spurred me to new heights and simultaneously crashed against reality. In pursuit of the big prizes, I was willing to slowly sell off the things I cared about most to get what I wanted, until I woke up to …

Single Nucleotide Polymorphisms In Dna Repair And Oxidative Stress Genes, And Their Interaction With Antioxidants On Prostate Cancer Aggressiveness, Samuel Antwi Dec 2014

Single Nucleotide Polymorphisms In Dna Repair And Oxidative Stress Genes, And Their Interaction With Antioxidants On Prostate Cancer Aggressiveness, Samuel Antwi

Theses and Dissertations

Prostate cancer is the leading invasive malignancy and the second most common cause of cancer death among American men. Despite compelling evidence that oxidative stress, ineffective DNA damage repair, and habitually low antioxidants intake may act in tandem to influence prostate carcinogenesis, few studies have examined gene-diet interactions involving these risk factors. Even fewer studies have examined such interactions in relation to prostate cancer aggressiveness. This study investigated whether single nucleotide polymorphisms (SNPs) in DNA repair- and oxidative stress-related genes modulated associations between antioxidant intake and prostate cancer aggressiveness. We utilized data from the North Carolina-Louisiana Prostate Cancer Project (PCaP) …

Perception Of Police In Public Housing Communities, Taylor Brickley Dec 2014

Perception Of Police In Public Housing Communities, Taylor Brickley

Theses and Dissertations

Research on the relationship between police and citizens consistently finds that attitudes toward police (ATP) are least positive among black citizens in areas of concentrated disadvantage. While much of the research in this area focuses specifically on ATP among young black males in low-income communities because they have the most contact with police, there has been relatively little research that has included older and/or female residents. Additionally, research has yet to examine ATP in racial and economic enclaves that may have different social and environmental characteristics than the surrounding community. This study utilizes in-depth interviews with 60 residents of two …

Attention-Deficit/Hyperactivity Disorder And Academic Performance: Student Engagement In The Classroom, Emily B. Mancil Dec 2014

Attention-Deficit/Hyperactivity Disorder And Academic Performance: Student Engagement In The Classroom, Emily B. Mancil

Theses and Dissertations

Youth with Attention/Deficit-Hyperactivity Disorder (ADHD) have many obstacles to positive development (including difficulties in school settings) and are in need of support. However, few studies have focused on the ways in which positive factors, such as student engagement (SE), may be beneficial for this population to identify strategies for supporting their strengths. Although many studies have examined academic and behavioral aspects of SE, few studies have examined the psychological (i.e., teacher-student relationships, peer support for learning, family support for learning) and cognitive (i.e., control and relevance of school work, future aspirations and goals, extrinsic motivation) sub-components of engagement. The current …
