Untold Stories And Silenced Voices: Lives Inside A North Georgia Elementary School, Donna S. Troupe

College of Graduate Studies: Theses & Dissertations

This is an inquiry into the lived experiences of Southern, white, female teachers who teach their overwhelmingly Southern, white student populations in a rural/suburban North Georgia elementary school. I explore the obstacles and challenges they face as they experience the negative and crippling effects of the policies and practices forced upon them in their teaching and learning environments. Drawing upon the theoretical works of Dyer (1997), McIntosh (2012), Anderson & Collins (2007), Morrison (1992), Jupp (2013), Sleeter (1993, 2003), Smith (1944,1949), and hooks (1992) on race and critical white studies; the works of Apple (2001,2008), McLaren (1998), Foucault (1977), Freire …

College of Graduate Studies: Theses & Dissertations

In this study the African American childcare provider’s life experiences are heard through the use of narrative inquiry and oral history. Often perceived as individuals who could not become teachers in the K-12 system, the women presented tell the reader in their own words what factors lead them to becoming childcare providers. By focusing on oral history, the stories told solidify the idea of the past creating the present. Education, religion, socioeconomics, culture and racial issues play an important part in each person’s life. Therefore, these factors were the main focus when participants were asked to describe their lives. The …

Impact Of Community-Based Interventions On Hiv Knowledge, Attitudes And Transmission, Rehana A. Salam, Sarah Haroon, Hashim H. Ahmed, Jai K. Das, Zulfiqar A. Bhutta

Department of Paediatrics and Child Health

In 2012, an estimated 35.3 million people lived with HIV, while approximately two million new HIV infections were reported. Community-based interventions (CBIs) for the prevention and control of HIV allow increased access and ease availability of medical care to population at risk, or already infected with, HIV. This paper evaluates the impact of CBIs on HIV knowledge, attitudes, and transmission. We included 39 studies on educational activities, counseling sessions, home visits, mentoring, women's groups, peer leadership, and street outreach activities in community settings that aimed to increase awareness on HIV/AIDS risk factors and ensure treatment adherence.

Differential-Forms-Motivated Discretizations Of Electromagnetic Differential And Integral Equations, Qi I. Dai, Weng Cho Chew, Li (Lijun) Jun Jiang, Yumao Wu

Electrical and Computer Engineering Faculty Research & Creative Works

In this letter, we present a differential-forms-motivated procedure to unify and guide discretizations of differential and integral equations in computational electromagnetics (CEM). In order to solve such equations accurately, it is crucial to find an appropriate matrix representation of the governing differential or integral operator. Differential forms theory inspires a general procedure of selecting both expansion and test functions wisely. Many well-functioning discretizations in finite element method (FEM) and boundary element method (BEM) can be reinterpreted with this theory. Moreoever, our approach offers guidance for discretizing complicated problems where straightforward discretizations may not be available. © 2014 IEEE.

A Calderón Preconditioner For The Electric Field Integral Equation With Layered Medium Green's Function, Yongpin P. Chen, Sheng Sun, Lijun Jiang, Weng Cho Chew

Electrical and Computer Engineering Faculty Research & Creative Works

A Calderón preconditioner is developed for the analysis of electromagnetic scattering of perfect electrically conducting (PEC) objects embedded in a layered medium. The electric field integral equation (EFIE) is formulated with the kernel of layered medium Green's function to account for the effects from the multilayered background. The Calderón projector is derived based on the general source-field relationship and the extinction theorem for inhomogeneous environment in electromagnetic theory. The Calderón identities can be naturally deduced based on this projector, which is then leveraged to precondition the EFIE with layered kernel. An alternative implementation is then proposed to make the implementation …

A Rigorous Approach For The Radiated Emission Characterization Based On The Spherical Magnetic Field Scanning, Ping Li, Li (Lijun) Jun Jiang

Electrical and Computer Engineering Faculty Research & Creative Works

Electromagnetic radiated emissions from antennas, printed circuit boards (PCBs), and electronic devices are becoming increasingly critical to today's IC electromagnetic compatibility and interference properties. In this paper, a rigorous characterization approach is proposed. The electromagnetic field sampling over a spherical testing surface is applied to obtain the radiated magnetic field of the device under test (DUT) placed at the center of the sampling region. Using the dyadic Green's function (DGF) and Huygens' principle, the transformation from the sampled spherical tangential field to the far field is directly computed without resorting to the conventional inverse algorithm. The DGF considers the existence …

A Hybrid Time-Domain Discontinuous Galerkin-Boundary Integral Method For Electromagnetic Scattering Analysis, Ping Li, Yifei Shi, Li (Lijun) Jun Jiang, Hakan Baǧci

Electrical and Computer Engineering Faculty Research & Creative Works

A scheme hybridizing discontinuous Galerkin time-domain (DGTD) and time-domain boundary integral (TDBI) methods for accurately analyzing transient electromagnetic scattering is proposed. Radiation condition is enforced using the numerical flux on the truncation boundary. The fields required by the flux are computed using the TDBI from equivalent currents introduced on a Huygens' surface enclosing the scatterer. The hybrid DGTDBI ensures that the radiation condition is mathematically exact and the resulting computation domain is as small as possible since the truncation boundary conforms to scatterer's shape and is located very close to its surface. Locally truncated domains can also be defined around …

The Soft-Feedback Isi Canceller-Based Turbo Equalizer For Multilevel Modulations, Huang Lou, Chengshan Xiao

Electrical and Computer Engineering Faculty Research & Creative Works

In this paper, we investigate the soft-feedback equalizer (SFE) proposed by Lopes et al. for multilevel modulations. The SFE is based on InterSymbol interference canceller structure and is compared to both soft-decision feedback turbo equalizer (SDFE) and the exact solution of MMSE linear equalizer (Exact-MMSE-LE) by means of EXIT chart analysis and BER simulations. Interesting results reveal that, for multilevel modulations, the SFE not only exhibits the same low complexity, low SNR threshold and fast convergence as SDFE but also reaches matched filter bound after a large number of iterations. © 2013 Springer Science + Business Media New York.

An Accurate Frame Error Rate Approximation Of Coded Diversity Systems With Non-Identical Diversity Branches, Gang Wang, Jingxian Wu, Yahong Rosa Zheng

Electrical and Computer Engineering Faculty Research & Creative Works

This paper presents an accurate approximation of the frame error rate (FER) of coded wireless communication systems with receiver diversity, such as single-input multiple-output (SIMO) systems with maximum ratio combining (MRC) or hybrid automatic repeat request (HARQ) systems with Chase combining. The signals at different diversity branches experience independent but non-identically distributed Rayleigh fading. The FER approximation is obtained with a threshold-based method. Specifically, the threshold value, which is critical to the FER approximation accuracy, is modeled as a linear function of the frame length in the log-domain, with the slope and intercept of the linear function determined by the …

Aerogels As Diverse Nanomaterials, Abhishek N. Bang

Doctoral Dissertations

"Aerogels are 3-D light-weight nanoporous materials pursued for their low thermal conductivity, low dielectric constant and high acoustic attenuation. Those exceptional macroscopic properties of aerogels are dependent on the chemical nature of nanoparticles, complex hierarchical solid skeletal framework and porosity. Also, the free space can become host for functional guests such as pharmaceuticals. In chapter I, we investigated randomly mesoporous bio-compatible polymer-crosslinked dysprosia aerogels as drug delivery vehicles and demonstrated storage and release of drugs under physiological conditions. Comparative study with ordered and randomly mesoporous silica showed high drug uptake and slower release rate for random nanostructures (silica or dysprosia) …

Student Affairs Professionals’ Perceptions Of Campus Incivility, Amy J. Zieziula, Daniel W. Calhoun

Journal of Higher Education & Student Affairs

The purpose of this study was to gather data regarding student affairs professionals’ perceptions of student incivility and which acts of incivility are most often observed. Results from 409 participants suggested that student affairs professionals perceive that “very uncivil” acts are observed less often whereas acts that are perceived to be neither civil nor uncivil are witnessed more frequently. In addition, findings indicated that student affairs professionals are seeing an increase in uncivil acts related to social media and technology, and the manner in which students are using social media to vent frustrations with campus staff and their peers. Finally, …

Sexual Attitudes As Predictors Of Homonegativity In College Women, James G. Archibald, Tamera Dunn

Journal of Higher Education & Student Affairs

Rancorous attitudes toward lesbian women and gay men are widespread in the United States (Morrison, Parriag, & Morrison, 1999). Homonegativity is any prejudicial attitude or discriminatory behavior directed toward an individual because of his or her homosexual orientation (Morrison, McLeod, Morrison, Anderson, & O’Connor, 1997). A small amount of research has been done regarding women’s attitudes towards lesbians. The purpose of this study is to investigate the potential relationship between sexual attitude expression and homonegativity. It was hypothesized that females with conservative sexual attitudes would show higher levels of homonegativity, and females with liberal sexual attitudes should show more non-homonegative …

Banks, Marijuana, And Federalism Symposium: Marijuana, Federal Power, And The States, Julie Andersen Hill

Articles

Although marijuana is illegal under federal law, twenty-three states have legalized some marijuana use. The state-legal marijuana industry is flourishing, but marijuana-related businesses report diffi- culty accessing banking services. Because financial institutions will not allow marijuana-related businesses to open accounts, the mari- juana industry largely operates on a cash-only basis-a situation that attracts thieves and tax cheats. This Article explores the root of the marijuana banking problem as well as possible solutions. It explains that although the United States' dual banking system comprises both federal- and state- chartered institutions, when it comes to marijuana banking, federal regulation is pervasive and …

Individuals and organizations invest significant time and financial resources to comply with mandatory education and training requirements. Although the mandates and demand for CE and MCE continues to increase, there is minimal research on the efficacy of various delivery methods. The purpose of this study was to examine and document the efficacy of andragogical …

First-Year Male Students' Adherence To Traditional Male Gender Roles And Their Attitudes Toward Bystander Approach Behaviors To Stop Sexual Assault, Kamal M. Harb

Doctoral Dissertations

Sexual assault on university campuses may affect any person at any time. However, university-aged women are disproportionally affected by it, with 25% of women reporting being assaulted on campus, and 84% to 97.8% of them perpetrated by young, heterosexual men known to the victim. To curb sexual assault on the university campus, research studies have advocated for the bystander approach. It encourages bystanders (observers) to intervene and ultimately stop a potentially dangerous situation in which a friend or stranger may experience a sexual assault. Despite its popularity, research studies evaluating the bystander approach have reported, at best, modest success with …

Artist As Citizen: Transnational Cultural Work In The National Democratic Movement Of The Philippines, Ryan Anthony Leano

Doctoral Dissertations

The inspiration for this topic comes from my own experiences as a Filipino transnational cultural worker in this movement. There has been research done on Filipinos in the arts and social movements, however there is a paucity of information concerning Filipino cultural work. Cultural work and cultural workers are intentional in creating culture as an act of resistance to imperialism, as of the stories they tell though their creative work are not revealed much in mainstream media. Cultural workers also seek to debunk the myth of artists working in isolation from the community. As shared by the participants in this …

An Investigation Of Special Education Teachers' Perceptions Of The Effectiveness Of A Systematic 7-Step Virtual Worlds Teacher Training Workshop For Increasing Social Skills, Natalie Christina Nussli

Doctoral Dissertations

This study describes how a systematic 7-Step Virtual Worlds Teacher Training Workshop promoting inquiry, experiential learning, and sociocultural theory guided the enculturation of 18 special education teachers into three-dimensional virtual worlds. The main purpose was to enable these teachers to make informed decisions about the usability of virtual worlds for students with social skills challenges, such as students with autism. Mixed-methods data analysis and triangulation were based on the analysis of seven instruments. Six of the seven steps of the intervention received high ratings indicating its viability for teachers' professional development opportunities

Fiscal Federalism As Risk-Sharing: The Insurance Role Of Redistributive Taxation, John R. Brooks

Georgetown Law Faculty Publications and Other Works

In addition to funding government and redistributing income, a redistributive tax-and-transfer system, and a progressive income tax in particular, provides insurance against the risk of uncertain future income. By providing for high taxes for high incomes, and low taxes, exemptions, and transfers for low incomes, a progressive income tax lowers the volatility of potential after-tax income relative to a lump-sum tax. This insurance function is distinct from the redistributive function of the system, since it provides a direct risk-mitigation benefit to the taxpayer himself, rather than simply redistributing income from one taxpayer to another.

This article analyzes the question of …

Overrides: The Super-Study, Victoria Nourse

Georgetown Law Faculty Publications and Other Works

Overrides should be of interest to a far larger group of scholars than statutory interpretation enthusiasts. We have, in overrides, open inter branch encounters between Congress and the Courts far more typically found in the shadows of everyday Washington politics. Interestingly, Christiansen and Eskridge posit the court-congress relationship as more triadic than dyadic given the role played by agencies. One of their more interesting conclusions is that agencie are the big winners in the override game: agencies were present in seventy percent of the override cases and the agency view prevailed with Congress and against the Supreme Court in three-quarters …
