Living With Paine: The Age Of Reason In Nineteenth-Century American Literature, Joe Webb

Masters Theses

The completion of this thesis represents a reasonable stopping point after a year of detective work - a year spent trying to piece together one small story in the history of nineteenth-century American free thought. In July of 2005, I happened to pick up a copy of Thomas Paine's The Age of Reason at a bookstore in Chicago, and having nothing much to do for the next few hours, I sat down in a café and read the book cover to cover. I was captivated. My experience, in fact, was probably not unlike the experience of Mark Twain when he …

The Slave Trade, The Constitutional Convention, And The Compromises That Let To Union: A Reinterpretation, Ryan Ervin

Masters Theses

At the 1787 Philadelphia Convention, abolitionist and anti-slavery delegates were faced with a direct choice: they could either explicitly end the institution, or they could allow for it to continue. If they had decided to push for abolition, the confederation would almost certainly have dissolved into two or three separate sovereign confederacies or countries. If they chose not to endorse abolition within the text of the Constitution, they could still restrain the facilitator of slavery, the slave trade, and continue to endorse the institution's end, while also maintaining the Union.

Because they did not abolish slavery outright, these abolitionist and …

Coping Strategy Use And Resilience Among Children Reporting Victimization, Julie K. Gepner

Masters Theses

Prior studies have established the negative implications of peer victimization; additional literature has focused on how children cope with the negative effects of peer bullying. However, no current research has examined the specific coping strategies, which may result in resiliency to the negative effects of peer victimization. The present study examined victimization, coping strategies, and resilience in a sample of 143 third through sixth grade students. The results indicated that the coping strategy of seeking social support was associated with resiliency among victims of aggression. In contrast, coping using externalizing behavior was associated with significantly lower levels of resiliency. The …

Beaver Home Ranges And Movement Patterns On The Embarras River Watershed In East Central Illinois, Randall P. Havens

Masters Theses

The beaver (Castor canadensis) is an ecologically and economically important species that has been much studied and exploited during its long association with humans (Bradt 1938, Hodgdon 1978, Novak 1987, Muller-Schwartze and Schulte 1999). Beavers have been described as ecosystem engineers and a keystone species because of their ability to physically modify, maintain, or create wetlands thereby controlling resources used by other organisms and altering the physical state of the environment (Jones et al. 1994). They are capable of impacting the local environment through dam construction, selective tree harvest, and den construction. For example, beaver dams impact stream hydrology, nutrient …

Model Checking Control Communication Of A Facts Device, David Andrew Cape

Masters Theses

"This thesis concerns the design and verification of a real-time communication protocol for sensor data collection and processing between an embedded computer and a DSP. In such systems, a certain amount of data loss without recovery may be tolerated. The key issue is to design and verify the correctness in the presence of these lost data frames under real-time constraints. This thesis describes a temporal verification that if the end processes do not detect that too many frames are lost, defined by comparison of error counters against given threshold values, then there will be a bounded delay between transmission of …

The maintenance and repair work in the civil engineering infrastructures develops the production of huge wastes which causes the growth of waste piles, additional costs in construction projects and some environmental problems. If this waste is recycled and used again in construction projects, it will help to overcome the problems discussed earlier. Moreover, if natural aggregates are supplemented by recycled aggregate, it will preserve the natural resources and also put a pause in the deterioration of natural landscape.

This thesis addresses the importance of using recycled aggregate in concrete structures. Its practical feasibility in construction projects is studied in light …

Detecting And Mapping The Michigan Vegetation Tension Zone Using Ecological Indicators, Janice Marie Fulford

Masters Theses

Ecotones are areas of transition between adjacent ecosystems that exist at various geographic scales, and are useful in measuring climatic changes. Ecotones are defined by their length and breadth and the ability to detect and map an ecotone from a specific period in time would be useful in measuring current and future change.

The study focused on a 1880's vegetation ecotone in the center of Michigan's Lower Peninsula. This was achieved by deriving ecological variables from the U.S. public land survey's tree species data. These variables were then used to ascertain the length of the ecotone by finding the boundary …

Cloning, Overexpression, Purification And Characterization On N-Terminal Metal Binding Domains 5 And 6 Of Wilsons Disease Protein, David Achila

Masters Theses

Wilsons disease is an autosomal recessive disorder of copper metabolism which results from mutations in the gene encoding for Wilson disease protein (WDP). The cytosolic N-terminus of WDP comprises six metal binding domains each containing a conserved metal binding motif, GMXCXXC. The contribution of these metal binding domains to copper homeostasis is poorly understood. We have cloned, expressed and purified residues 485 to 633 corresponding to N-terminal metal-binding domains 5 and 6 of WDP (WD5-6). Two of the 3 disease causing mutations in the N-terminal metal binding domains of WDP occur one in each of these domains and the two …

Gambling On A Simulated Slot Machine Under Conditions Of Repeated Play, Andrew Ellis Brandt

Masters Theses

Three experiments using a parametric, single-subject design investigated gambling behavior in eight adult humans on a slot-machine simulation. Participants were staked with credits exchangeable for money prior to each session. Experiment 1 a was a systematic replication of Weatherly and Brandt (2004), which investigated the effects of percentage payback (the amount of money gained as a proportion of the amount of money bet) on gambling. Percentage payback was varied from 50% to 110% across conditions. Consistent with Weatherly and Brandt, gambling did not vary systematically across percentage-payback conditions. Experiment 1 b replicated Experiment 1 a but also included forced-exposure sessions …

Simulating Discriminatory Profiling, Oscar Neal

Masters Theses

There is a concern that racial profiling is being used to invoke searches and stops in spite of its violation of the fourth amendment. Simulation methods are used to study the correlation test of stops, searches and citations with race, age, and gender. The design uses sensitivity analysis of inputs to determine their relationship to outputs statistics of a police department's citations and stops. Experimental results are than used to verify and predict departmental bias. A simulation program written in Visual Basic is used as a tool to explore simulation techniques. A formulation of simulation uses in studying discriminatory profiling …

Hispanic Political Power: A Case Study Of Southwest Michigan, Jason Glatz

Masters Theses

This thesis examines the relationship between rising Hispanic immigration and its influence on voting patterns. It examines thirteen Southwestern Michigan counties and compares averaged Republican voting percentages from past elections for the U.S. House of Representatives with the 2000 election. Previous research has established that Hispanics, with the exception of Cubans, predominantly vote for Democratic candidates. If this relationship is true for Southwest Michigan, areas with increasing Hispanic populations should display diminishing Republican voting percentages.

A normal Republican vote was computed for 284 minor civil divisions from the period immediately preceding significant Hispanic immigration and was compared to the 2000 …

The Effects Of Feedback On Hourly Pay And Individual Monetary Incentives, Douglas A. Johnson

Masters Theses

The effects of performance feedback when individuals received fixed or individual incentive pay were examined. A 2 X 2 factorial design was used with approximately 30 college students in each group. Participants attended six experimental sessions. They entered the cash value of simulated bank checks presented on a computer screen. Monetary incentives increased the number of correctly completed checks (p = .000); however feedback had no effect (p = .825). Time spent working and rate of performance correlated strongly with the number of checks completed correctly, suggesting that both influenced the checks completed correctly. The results suggest that incentives increase …

The Journey Of A Social Movement: A Glimpse Into Hizb 'Allah And Its Integration Into The Lebanese Landscape, Lisa L. Peters

Masters Theses

Historically, research in Social Movement Theories has been limited to only certain aspects of a social movement, whether it was the impetus of the movement, explaining the reasons for its mobilization, how they recruit members and money, how social movements are able to function as an organization, or why groups suffer demise after flourishing for a period of time. This research attempts to build a framework of a particular social movement, Hizb'allah, a Shi'a Islamic movement based in Lebanon. This framework is built by extracting various elements from several social movement theories to explain and illustrate this movement's life course …

A K-Epsilon Extension For Wall-Bounded Flows On The Broadband Aeroacoustic System Simulator, David González

Masters Theses

The turbulence modeling capabilities of the Broadband Aeroacoustic System Simulator (BASS), an experimental code developed at NASA Glenn Research Center, have been extended to include wall-bounded flow capabilities. This was done by first validating the code's viscous solving routines by comparing numerical solutions to known, simple analytic solutions. Finally, the dynamics of the wall shear flows were accounted for with the use of wall-damping functions incorporated into the turbulence model. The results for both viscous and turbulence routines agree well with published data.
