The Grim Word: 'Home' In Fiction By Graham Greene, Geoff Cowgill

Masters Theses

Graham Greene's treatment of the subject of home in his writings is remarkably negative. Focusing on nine of his major novels (England Made Me, A Gun for Sale, Brighton Rock, The Heart of the Matter, The Quiet American, The Comedians, Travels with My Aunt, The Honorary Consul, and The Human Factor), this study explicates the ways in which home fails his characters. In this thesis, 'home' has been split into three facets: family, domicile and homeland. Each facet seems to promise benefits for the characters that don't materialize. The way in which Greene's writing promotes a betrayal of home reflects …

Bullying And Victimization In High School As Perceived By Female Students In A Midwestern University, Shannon Y. Schwab

Masters Theses

Bullying and victimization increased tremendously over the past 2 decades and are presently one of the most enduring and underrated problems in U.S. schools. Much of the research available on bullying has focused primarily on males; however, recently, research has shown that females are just as likely as males to engage in bullying behaviors. Unfortunately, female bullying occurs quite frequently, yet remains unrecognized because it is often overlooked. Females tend to prefer more indirect forms of bullying behaviors in order to keep it anonymous. The focus of the current research was to examine the nature and frequency of female bullying …

Soil Sisters: Independent Land Owning Women In Coles And Douglas Counties, Illinois, 1870-1930, Rachel E. Kleinschmidt

Masters Theses

In the Midwest during the late nineteenth and early twentieth centuries, many women owned and worked on farmland, but the male-dominated capitalistic farming system negated much of the legal and economic authority they had as farmers. Progressive Era changes in the farming system shifted family farming systems to profit-driven business-oriented farms, marginalizing women's productive contributions. Single and widowed women farmers in Coles and Douglas Counties in Illinois managed to retain ownership of farm land despite gender and legal biases inherent in common law practices defined by patriarchy.

A survey of local history sources, including federal census data, probate records, and …

No statistically significant differences were found between Blacks and Whites in attitudes toward Black-White interracial marriages and Black-White biracial identity. No statistically significant differences were found between men and women, either. The insiders' reports, however, contradicted these findings. Both Black-White interracial couple and Black-White biracial adult participants of this study reported …

An Exploration Of The Perception Of Collective Identity Threat Among Muslim Students In Higher Education, Donna Vitale

Masters Theses

The purpose of the present study was to examine the perspectives of Muslim students in higher education concerning their connections to campus based on their perceptions of collective identity threat. Collective identity exists when an individual holding group membership fears that in-group members' behavior will reinforce a negative stereotype about their group. Similarly, stereotype threats are personally relevant threats in which individuals may fear reinforcing the stereotype themselves (Cohen & Garcia, 2005). Research in the area of stereotype threat has high generalizability and can transfer to any race or gender (Steele, Spencer, & Aronson, 2002). For the purpose of the …

A Genetic Assessment Of The Red Squirrel In Illinois: Natives, Immigrants, Or Exotics?, William Beatty

Masters Theses

A small population ofred squirrels (Tamiasciurus hudsonicus) has existed in Iroquois County, Illinois since the 1970' s. The origin of this population is unknown, but some accounts suggest they are the offspring of released red squirrels from Minnesota. Alternatively, they may be a remnant Illinois population or more recent immigrants from Indiana. Finally, this population could reflect a mixed ancestry of the above scenarios. Mitochondrial DNA (mtDNA) was utilized to determine the genetic relationships among red squirrel populations in Illinois, Indiana, Michigan, Minnesota, and Wisconsin. My results showed low levels of haplotype diversity and nucleotide diversity in the Illinois sample. …

Beneficial Effects Of Estradiol Are Mediated Through Apoe, Aseem Hussain

Masters Theses

Estradiol is the primary premenopausal hormone circulating in women. It is a powerful hormone in the female body since it sends signals to the brain, regulates ovulation and menstrual cycle and acts on the nervous syste~ heart, breast and many other tissues in the body. However all estradiol production is stopped after menopause. Post menopausal women can develop a host of neurodegenerative diseases such as Alzheimer's disease. If the onset of progressive dementia is after menopause during loss of estradiol, it seems logical to assume that the lack of estradiol should have a big role to play in the pathogenesis …

Tracing Sperm In Multiply-Mated Female Anastrepha Suspensa, (Diptera:Tephridae), Preeti Dhakal

Masters Theses

Anastrepha suspensa females have four different sites of sperm storage in their reproductive tract, may mate with more than one male, and store sperm in differing amounts in each organ after copulation. In order to study the dynamics of sperm storage patterns and subsequent paternity outcomes, a method was developed for both genotyping and quantifying sperm in the spermathecae. Spermathecae were isolated and sonicated to remove maternal cells, and subsequently crushed between two microslides to release sperm from the capsule. After DNA isolation, microsatellite loci could be amplified by PCR for fragment analysis. A newly developed method was then used …

Influence Of Seed Source On Vegetative And Reproductive Performance Of Three Common Prairie Grasses Common In Grassland Restoration, Matt Burmeister

Masters Theses

Though tallgrass prairie once covered 250 million acres of the midwestem U.S, now less than one percent· of this original area is left. In recent years the restoration and reconstruction of tallgrass prairie has become more popular throughout the prairie region. There is evidence that local and distant populations may both be practical seed sources for ecological restoration projects. To address this basic issue in restoration, I tested the how performance of three grass species from different locations was affected by the distance from the restored area. Three species, Andropogon gerardii, Sorghastrum nutans and Panicum virgatum, of perennial grasses common …

Individual-Based Artificial Ecosystems For Design And Optimization, Shivakar Vulli

Masters Theses

"Individual-based modeling has gained popularity over the last decade, mainly due to the paradigm's proven ability to address a variety of problems seen in many disciplines, including modeling complex systems from bottom-up, providing relationship between component level and system level parameters, and discovering the emergence of system-level behaviors from simple component level interactions. Availability of computational power to run simulation models with thousands to millions of agents is another driving force in the widespread adoption of individual-based modeling. This thesis proposes an individual-based modeling approach for solving engineering design and optimization problems using artificial ecosystems"--Abstract, page iii.

Co-Optimization: A Generalization Of Coevolution, Travis Service

Masters Theses

"Many problems encountered in computer science are best stated in terms of interactions amongst individuals. For example, many problems are most naturally phrased in terms of finding a candidate solution which performs best against a set of test cases. In such situations, methods are needed to find candidate solutions which are expected to perform best over all test cases. Coevolution holds the promise of addressing such problems by employing principles from biological evolution, where populations of candidate solutions and test cases are evolved over time to produce higher quality solutions...This thesis presents a generalization of coevolution to co-optimization, where optimization …

Carbon Credits And Energy Subsidies In Economic Decision Making For Confined Animal Feedlot Operation Waste Treatment, Taresh Grover

Masters Theses

"Released waste into the environment has always had a societal cost. Current issues with swine waste suggest that improved treatment is needed as agricultural production has become more industry-like and also as we now globally value the mitigation of global warming. The current need for and the economic support of advanced waste treatment has converged for animal agriculture, and now improved waste treatment is possible with concurrent economic benefit through alternative energy and carbon emissions. Recent changes have resulted in renewal of interest in anaerobic digestion (AD) technology with methane capture and energy production. An economic model was constructed to …

Role Of Microtubules In Budding Yeast Cytokinesis, Su Young Park

Masters Theses

"Cytokinesis is an important step to finish cell cycle events and separate into two daughter cells. This event is driven by actomyosin ring contraction. In budding yeast, the mitotic exit network (MEN) controls completion of ana/telophase by signaling events. Bub2 is a mitotic exit network regulator and binds to Tem1p which is an important component in MEN. Mad2 is a component of a separate spindle checkpoint. Mad2 dependent pathway prevents the metaphase to anaphase transition under spindle damage. Because yeast cells have cell walls, septum formation follows actin ring contraction. Here it was investigated how microtubule defects affect cytokinesis in …

Aflp Fingerprint Analysis Of Hybrid Salamanders In The Missouri Caverns Section Of Onondaga Cave, Maria Louise Potter

Masters Theses

"Two species and one subspecies of salamander in the genus Eurycea, two species of Plethodon and one species of Typhlotriton (recently considered to be Eurycea) salamander currently reside in an area of Onondaga Cave known as the Missouri Caverns section. Due to the presence of two known interbreeding subspecies of salamanders, Eurycea Longicauda (Long-tailed salamander) and Eurycea longicauda melanopleura (Dark-sided salamander), the possibility may exist for interbreeding of one or all of these taxa. Specifically, it is hypothesized that the two species of Eurycea longicauda may interbreed with Eurycea lucifuga (Cave salamander). through visual assessment and phenotypic analysis, …

Co-Evolutionary Automated Software Correction: A Proof Of Concept, Joshua Lee Wilkerson

Masters Theses

"The task of ensuring that a software artifact is correct can be a very time consuming process. To be able to say that an algorithm is correct is to say that it will produce results in accordance with its specifications for all valid input. One possible way to identify an incorrect implementation is through the use of automated testing (currently an open problem in the field of software engineering); however, actually correcting the implementation is typically a manual task for the software developer. In this thesis a system is presented which automates not only the testing but also the correction …

An Approach For Human Swarm Interaction, Shishir Bashyal

Masters Theses

"This study shows that appropriate human interaction can benefit a swarm of robots to reach to goal more efficiently. The common belief in swarm robotics that user intervention adversely affects intelligence of the swarm is studied carefully to show that the traditional human-robot interaction approaches are not suitable for human swarm interaction. A set of desirable features for human swarm interaction is identified and an interaction architecture is proposed that has all of the desirable features. A swarm simulation environment is then created that allows simulating a swarm behavior in an indoor environment. Three different applications of the swarm are …

Synthesis Of Nanostructured Conducting Polymers And Their Application As Gas Sensors, Zhe-Fei Li
