The Effects Of Supplemental Educational Services On Student Achievement, Regina F. Miller

Theses and Dissertations

Supplemental educational services (SES) are a core component of the No Child Left Behind Act of 2001 (NCLB) that provide free academic assistance in reading, language arts and mathematics for eligible students. Supplemental educational services include tutoring and other educational interventions that align with the state's academic content standards provided outside of the regular school day. Despite four years of supplemental services educational and millions of dollars spent, little is known about the effects of SES on student achievement. This study hypothesized that after the sixth month of SES tutoring, students in the experimental group would achieve higher scores on …

An Investigation Of Teachers' Perceptions Of School Psychologists, Noelle Bisinger

Theses and Dissertations

The purpose of this study was to investigate public school teachers' general knowledge and perceptions of school psychologists. This research examined 144 Kindergarten to 12th grade teachers' familiarity and interaction with school psychologists. Self-reported measures of school psychologists' helpfulness, performance, and general knowledge of school psychologists' duties and responsibilities were evaluated. Information pertaining to teachers' specialization, employment history, student population characteristics, and school size were also considered. It was hypothesized that years of teaching experience, teacher type (whether special or general education), and school population size would effect the ratings of school psychologists on all three subscales. A few significant …

Determinants Of International Long-Distance Eldercare: Evidence From Ghanaian Immigrants In The United States, Stephen Kodwo

Theses and Dissertations

Studies of Ghanaians who have immigrated to the United States indicate that both economic and emotional support continue to be provided to non-migrant families in Ghana. However support to “family relatives” has been studied generally, without specifying age. Thus, relationships between immigrants and their elderly relatives, particularly those who may be frail and vulnerable, have not been the focus of previous research. In addition, it is necessary to examine the dynamics that shape attitudes towards elderly people, and which in turn influence eldercare patterns among Ghanaian immigrants. Based on the literature, the researcher identified four factors relevant to international long-distance …

Blood Knot, William Nicholas White

Theses and Dissertations

This collection of original poetry is preceded by a critical introduction that details how Marianne Moore and Elizabeth Bishop’s similar aesthetics in poetry have influenced my own. The following poems focus on themes that challenge the nature of “manhood,” particularly the archetype of Southern masculinity, and highlight characters who struggle to understand themselves, their desires, and their society. The critical essay tracks how Bishop’s personifications, as she grows as a poet and as her narrator’s “drive into the interior” of nature, become harder to define and control and how this loss of control precipitates a jubilant self-awareness—an awareness of the …

Campus Emergency Evacuation Traffic Management Plan, Di Wu

Theses and Dissertations

This thesis was motivated to simulate the evacuation traffic of Mississippi Stated University (MSU) main campus using the Path-Following logic of TSIS/CORSIM and to evaluate a set of traffic management plans. Three scenarios of traffic management plans were developed and tested. A NCT of 123 minutes was projected if evacuate without any plan. In comparison, under a pre-planned traffic management plan the NCT would decrease to 39 minutes. Further, if implement contra flow the NCT would reduce to 21 minutes. If even further adjust the signal timing plans at the university exits a NCT of 20 minutes would be achieved. …

Educational Counter Culture:Motivations, Instructional Approaches, Curriculum Choices, And Challenges Of Home School Families, Kenneth Vance Anthony

Theses and Dissertations

This project is a case study on the vertical and horizontal occupational structures of physical therapy and how gender attitudes on opportunities can influence one’s workplace satisfaction. The theoretical perspective is based upon a gendered organizational theory and organizational justice operating in a latent manner through gendered opportunities on workplace satisfaction. Horizontal segregation (location and specialty) has been linked to gender essentialism, while vertical hierarchy (work continuity, earnings, and supervisory duties) has also been linked to male primacy. Workers’ perceived attitudes about opportunities for women (promotions and jobs) can potentially influence the outcome of job satisfaction. The 2004 Physical Therapy …

Evaluation Of The Program Delivery Of Every Women's Life In Virginia, Landolt Susan Kenney

Theses and Dissertations

Introduction: Among women, breast cancer is the most prevalent cancer and the second leading cause of cancer death. Although technology advances have improved survival rates for breast cancer overall, improvements have not been universally experienced by all socioeconomic and racial groups. Known determinants of breast cancer care disparities include socioeconomic status, race, age, and social support. As a part of the Breast and Cervical Cancer Mortality Prevention Act of 1990 and with the help of CDC funding, the Virginia Breast and Cervical Cancer Early Detection Program (BCCEDP) or Every Woman’s Life (EWL) was created. EWL provides breast cancer screening to …

A Dash Of Sufferage Spice: Rural And Urban Ethnicity Construction In The Transnational Women's Suffrage Movement, Anna M. Peterson

Theses and Dissertations

The women's suffrage movement in Europe and the United States led to female enfranchisement in much of the West in the early twentieth century. Suffrage historiography, however, places too much emphasis on a middle-class history of urban white women's struggle to win the vote. This traditional scholarship not only lacks a thorough class-based analysis but also fails to examine ethnicity's role in the American women's suffrage movement as well as larger transnational connections.

Research on the construction of Norwegian ethnicity and its corresponding influence on Norwegian-American support of women's suffrage contributes to filling this historiographical gap. In addition, the influence …

This research builds on the literature about power and performance, offering new theory that extends the literature by accounting for the transformational effects of information technology. The role of information technology in the relationship between organizational power and performance is unclear in the literature. Management literature offers theories describing the relationship between power and performance. IS literature investigates the relationship between information technology (IT) and power and between information systems technology and performance, but is silent on the impact of IT on the relationship between power and performance. The nature of this relationship – direct, moderating, or indirect – is …

Stratified Neighborhoods, Stratified Schools: Intradistrict Transfer And Racial And Socioeconomic Stratification, Elisabeth Stuart Larsen

Theses and Dissertations

Intra-district transfer policies allow students to attend any school within a district and thus may have unique consequences for stratification within a district. If parents make choices based on common academic interests, this policy can create racial and socioeconomic integration across the schools in a district. However, socially motivated choices may lead to the creation of increasingly stratified zones. This study examines one urban school district with an intra-district transfer policy to examine if the schools in the district become more racially and economically stratified under the choice policy and if the level of stratification at family's zoned schools is …

Molecular Systematics Of Spiny Pocket Mice (Subfamily Heteromyinae) Inferred From Mitochondrial And Nuclear Sequence Data, Melina Crystal Williamson

Theses and Dissertations

This study aims to determine species-level relationships within the genus Heteromys, as well as generic-level relationships among members of the subfamily Heteromyinae using a phylogenetic framework. Molecular sequence data were generated from two mitochondrial genes (cytochrome b and cytochrome oxidase I) and three nuclear gene segments (β-fibrinogen, engrailed protein II, and myosin heavy chain II), and analyzed under maximum parsimony, maximum likelihood, and Bayesian optimality criteria to infer relationships. Chapter 1 focuses on the phylogenetic and taxonomic implications for Heteromys from the analyses of sequence data. Phylogenies also provided a framework for delimiting species boundaries within the wide-ranging Heteromys desmarestianus …

Place Names In Israeli Sign Language, Bettina Revilla

Theses and Dissertations

One of the obstacles in translating the Hebrew Scriptures into sign language is the lack of signs for Biblical places in most sign languages of the world. What solutions are there? One possibility is to borrow existing signs for Biblical places from another sign language, particularly from Israeli Sign Language, since Israeli Deaf already have signs for the places where they live.

There is a trend towards borrowing foreign place name signs (toponyms), especially when a language does not have a sign. This research provides a corpus of Israeli Sign Language (ISL) toponyms for ninety-two place names, documenting in photos …

Speaking Of Myself: Independence, Self-Representation, And The Speeches Of Rudyard Kipling, Jacob M. Wilkes

Theses and Dissertations

Rudyard Kipling is a man of immense diversity. He successfully managed to write for over half a century in a variety of genres: short story, travelogue, ballad, personal narrative, and news reporting, to name only a few. While doing so, Kipling readily interacted with a range of subjects and created a multitude of ideas. Likewise, on a personal level, Kipling led an immensely diverse life. He could easily claim four separate continents as home, living variously in India, the United States, England, and South Africa. By profession he was a writer, but as an observer he was so skilled that …

Exploitation Of Geographic Information Systems For Vehicular Destination Prediction, Richard T. Muster

Theses and Dissertations

Much of the recent successes in the Iraqi theater have been achieved with the aid of technology so advanced that celebrated journalist Bob Woodward recently compared it to the Manhattan Project of WWII. Intelligence, Surveillance, and Reconnaissance (ISR) platforms have emerged as the rising star of Air Force operational capabilities as they are enablers in the quest to track and disrupt terrorist and insurgent forces. This thesis argues that ISR systems have been severely under-exploited. The proposals herein seek to improve the machine-human interface of current ISR systems such that a predictive battle-space awareness may be achieved, leading to shorter …

Performance Enhancements Of Ranging Radio Aided Navigation, Patric J. Ernsberger

Theses and Dissertations

Determining the position of team members is always useful information, whether it is a team of firefighters fighting a blaze or combatants clearing a building in the field. This information becomes even more decisive for the people responsible for their safety. To accomplish this in areas denied Global Navigation Satellite System (GNSS), such as around buildings or in steep valleys, alternative methods must be used. Radio ranging systems have been a part of the navigation solution for years. They unfortunately have poor performance in certain areas, such as inside buildings, due to multipath and other errors. To improve the position …

Hyperspectroscopy for fast transient events such as battlefield explosions is an undeveloped area of spectral imaging. This thesis is a discussion of issues involved with taking a laboratory design for a rotating prism hyperspectral chromotomographic (CT) instrument and producing a first approximation satellite payload design, operating scheme and trade space analysis to support demonstration of this technology in low-earth orbit. This instrument promises the capability of adding a time dimension to the normal spatial and spectral data produced by most hyperspectral imagers. The ultimate goal is to conduct experiments demonstrating the ultimate viability of spectral definition of transient combustion events …

A Comparison Of Two Common Classification Procedures For Economical Urban Land Cover Mapping Using Naip Imagery, Kent Lowell Simons

Theses and Dissertations

Detailed urban land cover maps are increasingly useful and important applications of remote sensing. Municipal agencies and others use land cover maps and data for numerous critical local planning and monitoring functions and for urban geographical research studies. Because of this, there is a demand for accurate urban land cover maps that can be produced quickly and economically. The availability of very high resolution multispectral imagery is an important factor in enabling such production, as the judicious selection of source imagery has a large impact on the resulting map products. Likewise, the implementation of appropriate digital image processing methods is …

Vision-Aided Cooperative Navigation For Multiple Unmanned Vehicles, Jason K. Bingham

Theses and Dissertations

In the recent past, a shift has taken place from manned to unmanned Intelligence, Surveillance, and Reconnaissance (ISR) missions. This shift has lead to an increase in the number of unmanned vehicles (UV) operating in a theater. Additionally, removal of the crew allows for a reduction in vehicle scale, which leads to an increased ability to operate in GPS degraded environments. With the loss of GPS signals the vehicles must rely on Inertial Navigation Systems (INS) which when reduced to an appropriate size are inherently inaccurate. This research endeavors to exploit three attributes of increased UV use for ISR missions. …

Using Multiple Robust Parameter Design Techniques To Improve Hyperspectral Anomaly Detection Algorithm Performance, Matthew T. Davis

Theses and Dissertations

Detecting and identifying objects of interest is the goal of all remote sensing. New advances, specifically in hyperspectral imaging technology have provided the analyst with immense amounts of data requiring evaluation. Several filtering techniques or anomaly detection algorithms have been proposed. However, most new algorithms are insufficiently verified to be robust to the broad range of hyperspectral data being made available. One such algorithm, AutoGAD, is tested here via two separate robust parameter design techniques to determine optimal parameters for consistent performance on a range of data with large attribute variances. Additionally, the results of the two techniques are compared …

Low Probability Of Intercept Waveforms Via Intersymbol Dither Performance Under Multipath Conditions, Jonathan K. Keen

Theses and Dissertations

This thesis examines the effects of multipath interference on Low Probability of Intercept (LPI) waveforms generated using intersymbol dither. LPI waveforms are designed to be difficult for non-cooperative receivers to detect and manipulate, and have many uses in secure communications applications. In prior research, such a waveform was designed using a dither algorithm to vary the time between the transmission of data symbols in a communication system. This work showed that such a method can be used to frustrate attempts to use non-cooperative receiver algorithms to recover the data. This thesis expands on prior work by examining the effects of …

Abstracting Gis Layers From Hyperspectral Imagery, Torsten E. Howard

Theses and Dissertations

Modern warfare methods in the urban environment necessitates the use of multiple layers of sensors to manage the battle space. Hyperspectral imagers are one possible sensor modality to provide remotely sensed images that can be converted into Geographic Information Systems (GIS) layers. GIS layers abstract knowledge of roads, buildings, and scene content and contain shape files that outline and highlight scene features. Creating shape files is a labor-intensive and time-consuming process. The availability of shape files that reflect the current configuration of an area of interest significantly enhances Intelligence Preparation of the Battlespace (IPB). The solution presented in this thesis …

Ohio River Denial As A Transportation Corridor And Its Economic Impacts On The Energy Industry, Caglar Utku Guler

Theses and Dissertations

What if the Ohio River is disrupted or denied partially or completely as a transportation corridor? A disruption may be either a natural or man-made disaster or a planned outage on the river’s lock and dam structures. Recent history is full of water transport disruption events having significant economic effects on the waterside industries. To assess coal-based economic impacts, we developed a network flow model to represent waterside coal-fired power plants situated along the Ohio River, their respective coal supplying mines, and the various transportation modes that connect them. We show that significant transportation-centric insights can be derived by using …

Satellite-Based Fusion Of Image/Inertial Sensors For Precise Geolocation, Neil R. Jesse

Theses and Dissertations

The ability to produce high-resolution images of the Earth’s surface from space has flourished in recent years with the continuous development and improvement of satellite-based imaging sensors. Earth-imaging satellites often rely on complex onboard navigation systems, with dependence on Global Positioning System (GPS) tracking and/or continuous post-capture georegistration, to accurately geolocate ground targets of interest to either commercial and military customers. Consequently, these satellite systems are often massive, expensive, and susceptible to poor or unavailable target tracking capabilities in GPS-denied environments. Previous research has demonstrated that a tightly-coupled image-aided inertial navigation system (INS), using existing onboard imaging sensors, can provide …

Position Concordant - Haptic Mouse, Ravi Rastogi

Theses and Dissertations

Haptic mice, computer mice modified to have a tactile display, have been developed to enable access to computer graphics by individuals who are blind or visually impaired. Although these haptic mice are potentially very helpful and have been frequently used by the research community, there are some fundamental problems with the mouse, limiting its acceptance. In this paper we have identified the problems and have suggested solutions using one haptic mouse, the VT Player. We found that our modified VT Player showed significant improvement both in terms of the odds of obtaining a correct responses and the time to perform …

Extended Holiday In Hurghada: Russian Women And 'Urfi Marriage As An 'Alternative Circuit Of Survival', Joanne Walby

Theses and Dissertations

“The effort to identify the enemy as singular in form is a reverse-discourse that uncritically mimics the strategy of the oppressor instead of offering a different set of terms” (Judith Butler, 1990: 18) Since the disintegration of the former Soviet Union, the ―trope of the trafficked Russian1 woman‖ has shaped the fears and perceptions of Russian women moving abroad for work. This discourse reifies fears of exploitation and victimhood but overlooks women‘s ability to rationally consider the risks and benefits of international migration for economic and social reasons. In Egypt, some negative stereotypes have been associated with the Russian population …
