Tropisetron As A Neuroprotective Agent Against Glutamate-Induced Excitotoxicity: Potential Mechanisms Of Neuroprotection, Michael M. Swartz

Masters Theses

Glutamate-induced excitotoxicity has been shown to play a key role in a number of neurodegenerative diseases of the central nervous system. Activation of nicotinic acetylcholine receptors (nAChRs) significantly protects various types of neuronal tissues from excitotoxic cell death (Kaneko et al., 1997; Dajas-Bailador et al., 2000; Wehrwein et al., 2004; Thompson et al., 2006). Tropisetron is a highly selective 5-HT3 class serotonin receptor antagonist that is also a partial acetylcholine (ACh) agonist of the α7 nAChR (Papke et al., 2005). In the current study we aim to determine if tropisetron offers protection to adult pig RGCs. We further aim to …

Laboratory Measures Of Aggression In Methadone Patients, Catherine M. Gayman

Masters Theses

Research suggests that current heroin users and individuals with a prior history of heroin dependence tend to be more aggressive than nonusers. No study has yet investigated whether opioid withdrawal affects aggressive responses on a laboratory task. The present study investigates whether mild opioid withdrawal affects aggression in six males and six females (N=12) undergoing methadone maintenance therapy. Aggressive behavior is measured using the Point Subtraction Aggression Paradigm (Cherek, 1981) computer task. Participants press buttons to earn money towards gift certificates. Money subtractions occur periodically and these are attributed to the behavior of a partner who is actually fictitious. Participants …

Stratigraphic Framework For Deposits Of The Saginaw Lobe, Barry And Calhoun Counties, Michigan, Usa, Stephanie K. Ewald

Masters Theses

Between 2006 and 2012, twelve rotasonic borings were drilled in Barry and Calhoun Counties, south central Michigan, as part of several Great Lakes Geological Mapping Coalition projects. Natural gamma ray logs were collected at every location and a detailed description and textural analysis was completed for seven of these cores. Five of the seven analyzed cores reached bedrock. Six of the seven borings were drilled north of the Kalamazoo Moraine of the Saginaw Lobe, which was constructed during retreat of the lobe after the Late Glacial Maximum. Five borings, drilled in tunnel valleys, indicate an increase in depth of tunnel …

Characterizing The Internal Architecture Of Upper Bone Spring Limestone Turbidites And Mass-Transport Deposits (Mtds) Utilizing High-Resolution Image Log Technology, Jason J. Asmus

Masters Theses

Characterization of reservoir scale (less than 1 meter thick) turbidites and mass-transport deposits (MTDs) using conventional subsurface data is complex, due to millimeter-centimeter scale architectural heterogeneity exhibited by these deposits.

Limited studies of the Bone Spring carbonate turbidites and MTDs within the Delaware Basin subsurface emphasized the use of conventional wire-line log and seismic data to evaluate reservoir potential of such strata. As a result, limited resolution offered by these data sets do not allow for accurate characterization of reservoir, and sub-reservoir scale, architectural and compositional variations.

The present investigation integrates high-resolution (centimeter scale) electrical borehole image logs with conventional …

Physics Faculty Use Of Example Solutions In Teaching Introductory Physics, William O. Mamudi

Masters Theses

This study investigates how physics faculty perceive and use features of example problem solutions. Thirty physics instructors from diverse institutions participated in semi-structured interviews. In addition to open-ended questions, three example problem solution artifacts were used to focus on specific solution features. Data were analyzed to identify instructors’ goals for the use of example solutions and whether their goals were consistent with the solution features that they valued and used. The study concludes that many faculty have three major goals: keeping students cognitively involved, helping students become better problem solvers, and supporting students in learning physics. The study also found …

The Effect Of Innovative Technology On Seatbelt Use, Bryan W. Hilton

Masters Theses

A previous pilot study documented that providing sustained haptic feedback to the gas pedal when a driver exceeded 25mph with his seatbelt unbuckled and removing the feedback contingent on seatbelt use increased seatbelt use in 7 commercial drivers. This study replicated this effect with 20 young drivers who did not consistently wear their seatbelt.

In the current study unbuckled drivers received increased accelerator pedal resistance when they exceeded 20 mph. A non-concurrent multiple baseline design was employed for this study. The dependent variable was percentage of trips driven without seatbelt use. The independent variable was an increase accelerator pedal resistance …

"His Head Rolled Forth Onto The Floor:" Women, The Abject, And The Male Gaze In Old English Poetry, Jaime Michelle Myers

Masters Theses

Old English poetry features several female characters who challenge androcentric authority by violently killing men. I argue in this thesis that three of these women—Modthryth, Grendel’s mother, and Judith—are linked together by their rejection or reversal of the male gaze. In their forceful refusal to be visually objectified, each character is portrayed as abject—outside of normal and outcast from community. They cause disorder, illustrate the fragility of androcentric control, and force a confrontation with death. In so doing, they create ambiguity and, at times, reverse the subject/object and masculine/feminine gender binaries.

Early Arrest Mutant Ogre: A Defect In Cytokineis Caused By A Mutation In The Gene Racgap1, April Wicklund

Masters Theses

The early arrest mutant ogre, isolated in the Tübingen screen, has a block in cytokinesis (Kane et al., 1996). Here I use genetic and molecular techniques to demonstrate that the ogre phenotype is caused by a lesion in the gene encoding Racgap1. I performed fine mapping studies using microsatellite markers to a 0.15 cM region containing the ogre locus. DNA sequence data revealed a nonsense mutation in the Racgap1 gene of ogre mutants, and in situ hybridization experiments showed a loss of racgap1 mRNA at later stages of development, likely by nonsense mediated decay. This evidence supports the abolishment …

Faunal Distribution And Relative Abundance In A Silurian (Wenlock) Pinnacle Reef Complex - Ray Reef, Macomb County, Michigan, Jennifer L. Trout

Masters Theses

Niagaran (Silurian) reefs are important sources of hydrocarbons in the Michigan Basin. In addition, some of these reservoirs have been used for gas storage and may be potential CO2 sequestration sites.

Despite extensive research on Niagaran reefs, most studies concerning faunal abundance and distribution have been qualitative studies conducted by paleontologists with an emphasis on taxonomy, paleoecology, and evolution.

This study is the first quantitative study of relative abundance and general distribution of fauna throughout a single Wenlock reef located in the southern trend of the Michigan Basin. This study will build on previous work done by WMU students and …

"Make Over Your Body": Conflicting Messages In Women's Fitness Magazines, Joy Zoodsma

Masters Theses

SHAPE Magazine is a women's fitness magazine that has been consistently popular since its initial publication in 1981. This study explores how the messages of health and beauty in this publication have evolved over the last three decades, especially in response to the cultural imperatives of consumerism and feminism. It critically analyzes the visual and textual messages on SHAPE Magazine covers and in letters from the editor, which offer important examples of the ways in which SHAPE attempts to “hail” readers – to draw them in, to convince them that what the magazine has to offer is relevant to their …

Factors Influencing The Spatial And Temporal Distrubtion Of Primary Productivity And Community Respiration In The Mississippi Coastal Estuarine Region, Ryan Anthony Vandermeulen

Master's Theses

This study describes the spatial and temporal distribution of net primary productivity (NetPP) and respiration (RESP) in relation to the biogeochemical, optical, and hydrographic variability in the Mississippi Sound and Mississippi Bight over the course of one year. Surface in-situ measurements of NetPP and RESP were regularly determined at two stations by a time-course detection of dissolved oxygen (DO) using novel optode technology. In addition, various biogeochemical, optical, and hydrographic parameters were examined over 14 stations throughout the estuary over a year, using ground and satellite (MODIS Aqua) measurements. In this study, consistently low dissolved inorganic N:P ratios (average N:P …

Analyzing Revenue Sharing And Buyback Contracts: An Experimental Study, Chinthana Ramaswamy

Graduate Masters Theses

This paper considers a standard newsvendor problem in a two-echelon supply chain setup. We use an experimental approach to investigate the deviation of decision makers from choosing optimal values in the context of supply chain contracts. Literature suggests that the coordinating contracts, such as revenue sharing or buyback contracts, do not necessarily improve the performance. Approaches to improve the existing revenue sharing and buyback contracts are examined in this paper. A rational supplier, who is likely to commit decision errors, sets the contract parameters to a retailer. These approaches are observed in a laboratory setting where human subjects are used …

Bereavement Among Urban University Students: The Role Of Meaning Making In Adjustment To Loss, Rebecca L. Norris-Bell

Graduate Doctoral Dissertations

Employing Neimeyer's theory of meaning reconstruction as a guiding framework, this study examined meaning making in a diverse sample of bereaved university students. The aims of this study were to 1) identify types of meanings made about loss, 2) examine socio-demographic and bereavement-related characteristics that might influence meaning making, and 3) investigate associations between types of meanings and post-loss psychological adjustment. Participants were 229 students from an urban commuter university. This was a cross-sectional study, employing self-report data collected on a secure, Web-based system. Participants were 18 years or older and had experienced the loss of a friend or family …

Being A (Good) Student: Conceptions Of Identity Of Adult Basic Education Participants Transitioning To College, Mina Reddy

Graduate Doctoral Dissertations

This study examines the perceptions of identity of a category of students that has rarely been studied in the context of higher education. These are adults who have participated in GED preparation or English for Speakers of Other Languages (ESOL) courses in Adult Basic Education (ABE) programs. A college education is increasingly necessary for individual economic success and a higher quality of life, and a college-educated workforce is a major element in national economic competitiveness. Rates of college enrollment and persistence of ABE students, however, are low. The study seeks to determine how ABE students and graduates conceive of their …

Physical Sciences Publications

We present the results of a joint observational campaign between the Green Bank radio telescope and the VERITAS gamma-ray telescope, which searched for a correlation between the emission of very-high-energy (VHE) gamma rays (E γ > 150 GeV) and giant radio pulses (GRPs) from the Crab pulsar at 8.9 GHz. A total of 15,366 GRPs were recorded during 11.6 hr of simultaneous observations, which were made across four nights in 2008 December and in 2009 November and December. We searched for an enhancement of the pulsed gamma-ray emission within time windows placed around the arrival time of the GRP events. …

The Impact Of Freeway Traffic Conditions On In-Vehicle Exposure To Ultrafine Particulate Matter, Miguel A. Figliozzi, Alexander Y. Bigazzi

Civil and Environmental Engineering Faculty Publications and Presentations

There is evidence of adverse health impacts from human exposure to traffic-related ultrafine particulate matter pollution. As more commuters are spending a significant portion of their daily routine inside vehicles, it is increasingly relevant to study exposure levels to harmful pollutants inside the vehicle microenvironment. This study is one of the first research efforts to combine detailed freeway traffic data (at 20 s intervals) and in-vehicle ultrafine particulate (UFP) exposure data under varying vehicle ventilation conditions. Results show that due to negative correlation between traffic speed and density, traffic states have a small but significant impact on in-vehicle UFP concentrations, …

Carbon And Nitrogen Dynamics In High Intensity Minimal Exchange Shrimp (Litopenaeus Vannamei) Raceways, John Henry Francis

Master's Theses

Three separate shrimp (litopenaeus vannamei) growouts were examined at The University of Southern Mississippi's Thad Cochran Marine Aquaculture Center. The objectives of this project were to (1) determine if there was a significant difference in any water quality parameters between the 2 density treatments, (2) construct carbon and nitrogen budgets to see where the carbon and nitrogen went in the system for all growouts, (3) determine if plastic media had any effects on water quality parameters and shrimp production, (4) determine if plastic media allowed for a nitrifying bacteria population to establish more rapidly, (5) determine if the …

"We Need The Storm, The Whirlwind, The Earthquake": The Intersection Of Language And Violence In Nat Turner's "Confessions" And Frederick Douglass's My Bondage And My Freedom, Allison L. Tharp

Master's Theses

Resistance literature is an established genre, dating back to the late eighteenth century, but it underwent a rhetorical revision as slavery increased within the United States in the years leading up to the Civil War. As slaves and free blacks began to rebel against their oppressed condition, they "stole" two prominent tools whites used_ to - oppress slaves: language and violence. Frederick Douglass's My Bondage and My Freedom is a self-conscious revision within resistance literature that argues for national change by advocating physical violence with written language. Reading this text as an intertext with Nat Turner's "Confessions" reveals the ways …

Moral Responsibility For Computing Artifacts: "The Rules" And Issues Of Trust, Frances S. Grodzinsky, Keith W. Miller, Marty J. Wolf

School of Computer Science & Engineering Faculty Publications

“The Rules” are found in a collaborative document (started in March 2010) that states principles for responsibility when a computer artifact is designed, developed and deployed into a sociotechnical system. At this writing, over 50 people from nine countries have signed onto The Rules (Ad Hoc Committee, 2010). Unlike codes of ethics, The Rules are not tied to any organization, and computer users as well as computing professionals are invited to sign onto The Rules. The emphasis in The Rules is that both users and professionals have responsibilities in the production and use of computing artifacts. In this paper, we …

Effective Computer Programming Instruction For Pre-University Albanian Students, Robert Mccloud, Ardiana Sula

School of Computer Science & Engineering Faculty Publications

The relationship between pre-university students and technology is frequently overrated. While we receive glowing reports about how young people are knowledgeable about computers, the truth is that their knowledge is typically about computer content and the manipulation of applications. Young students too often treat the actual programming and understanding of computers as a sort of magical mystery.

In this paper we look at a new Albanian initiative to identify and nurture the most talented of our pre-university students. In particular we look at contributions to the goal of making Albanians the most talented programmers in this area of Europe.

Lean And Mean: Workplace Culture And The Prevention Of Workplace Bullying, Andra Gumbus, Patricia Meglich

WCBT Faculty Publications

Workplace bullying has become a hot topic in the popular press as well as scholarly literature. Compared to targets of sexual harassment, bullied workers quit their jobs more often, are more unhappy, stressed at work, and less committed to the workplace. Little is done about it because there currently is no US law against bullying and often the only recourse for targets is to quit their jobs. We present a case study and then review various legal remedies and sample company policies to explore the actions organizations might take to eliminate this destructive workplace behavior.

Substantive Change Policy

Academic Affairs Policies

Georgia Southern University’s Substantive Change Policy follows the policies in effect at our accrediting body, the Southern Association of Colleges and Schools Commission on Colleges (SACSCOC) as well as at the University System of Georgia (USG). All campuses need to be aware of both of these policies when submitting curriculum changes; however, the Provost’s Office holds responsibility for communicating all substantive changes to the Board of Regents and SACSCOC on behalf of the President of Georgia Southern University.

Residential Grid-Tied With Battery Backup Photovoltaic System, Thomas Stobuagh

Electrical Engineering

When power outages occur, many homes are left without power for some time as they are dependent on the power grid. This project aims to design a residential grid tied battery backup photovoltaic system that will provide up to 7.2kW in an area that gets 5.36-5.49 kWh/m2/day [1] to support a home with an average daily usage of 28.4 kWh/day. To effectively use this system the house remains connected to the electric utility at all times, so any power needed above what the solar system can produce is simply drawn from the utility. It includes battery backup or uninterruptible power …

Examining Slot Machine Play With Varying Percentages Of Losses Disguised As Wins, Johnna L. Dunning

Research Papers

When playing on multiline slot machine games, small “wins” often amount to less than the original spin wager, which results in a financial loss to the gambler. However, the gambler may feel as if he is winning because these “wins” are paired with audio-visual feedback. The influence of losses disguised as wins was examined to determine if this had an influence on latency, trial ratings, and the number of trials played. Thirty-one participants played a minimum of 50 trials on a simulated multi-line slot machine. The participants were divided into three groups with 16%, 30%, and 46% of trials being …

Reassessing The Impact Of Inflation Targeting In Emerging Market Economies, Babatunde Aiyemo

Research Papers

In this paper, we subject a seeming consensus on the impact of inflation targeting in emerging market economies to some robustness assessments. First we report performance along carefully redefined country brackets, we find little evidence to support the notion that economies with inflation targeting policies performed better than non-targeting economies in terms of GDP growth, inflation and economic volatility. In fact, there is a suggestion in the results that amongst certain clusters of economies, certain restrictive aspects of the policy actually inhibit growth

In a subsequent assessment, we control for extent of development using specific country proxies but equally observe, …

Regular Homotopy Of Closed Curves On Surfaces, Katherine Kylee Zebedeo

Boise State University Theses and Dissertations

The use of rotation numbers in the classification of regular closed curves in the plane up to regular homotopy sparked the investigation of winding numbers to classify regular closed curves on other surfaces. Chillingworth [1] defined winding numbers for regular closed curves on particular surfaces and used them to classify orientation preserving regular closed curves that are based at a fixed point and direction. We define geometrically a group structure of the set of equivalence classes of regular closed curves based at a fixed point and direction. We prove this group structure coincides with the one introduced by Smale [9] …

Evaluation Of Multiple Schedules With Naturally Occurring And Contrived Discriminative Stimuli Following Functional Communication Training, Kenneth D. Shamlian Psyd

All Student Scholarship

The purpose of this dissertation is to describe a doctoral research study designed to compare use of contrived and naturally occurring discriminative stimuli when using multiple schedules to thin reinforcement following functional communication training and their subsequent efficacy when introduced to novel contexts. Results indicated for one participant training with contrived stimuli was most effective, both contrived and naturally occurring stimuli were similarly effective for a second, and further modifications of a) pairing specific therapists to training conditions and, (b) adding toys during EXT components were necessary for either training condition to be effective for a third. For one participant, …

Electron Self-Trapping In Ge2 Se3 And Its Role In Ag And Sn Incorporation, Arthur H. Edwards, Kristy A. Campbell, Andrew C. Pineda

Electrical and Computer Engineering Faculty Publications and Presentations

We present a set of density functional theory (DFT) calculations on the electronic structure of Ag and Sn in Ge₂ Se₃ in a periodic model. We show that electron self-trapping is a persistent feature in the presence of many defects. Ag and Sn autoionize upon entering Ge₂ Se₃ becoming Ag₊ and Sn₂₊ , respectively, and the freed electrons self trap at the lowest energy site. Both Ag and Sn can substitute for Ge, and we present formation energies as a function of Fermi level that show that Sn can substantially alter the incorporation of …
