Comparing The Statistical Tests For Homogeneity Of Variances., Zhiqiang Mu

Electronic Theses and Dissertations

Testing the homogeneity of variances is an important problem in many applications since statistical methods of frequent use, such as ANOVA, assume equal variances for two or more groups of data. However, testing the equality of variances is a difficult problem due to the fact that many of the tests are not robust against non-normality. It is known that the kurtosis of the distribution of the source data can affect the performance of the tests for variance. We review the classical tests and their latest, more robust modifications, some other tests that have recently appeared in the literature, and use …

Designed For The Good Of All: The Flushing Remonstrance And Religious Freedom In America., Tabetha Garman

Electronic Theses and Dissertations

On December 27, 1657, the men of Flushing, Long Island, signed a letter of protest addressed to the Governor-Director of New Netherlands. Though the law of the colony demanded otherwise, the men of Vlissengen pledged to accept all persons into their township, regardless of their religious persuasion. Their letter, called the Flushing Remonstrance, not only defied the laws of one of the most powerful, religious governors of the colonial age, it articulated a concept of religious freedom that extended beyond the principles of any other contemporary document.

Given its unique place in early American colonial history, why have historians not …

American Reeducation Of German Pows, 1943-1946., Pamela Croley

Electronic Theses and Dissertations

The United States held almost 500,000 enemy combatants within her borders during World War II. Out of those 500,000 men, 380,000 were from Nazi Germany. Nazi POWs were confined to camps built near small rural towns in almost every state. It was not something that was well known to the American public. Even less known was the American Military's effort, through reeducation, to introduce Hitler's soldiers to a new political ideology-democracy.

The Internal Odyssey Of Identity: James Baldwin, Go Tell It On The Mountain, And History., Brent Nelson Lamons

Electronic Theses and Dissertations

This study investigates how James Baldwin thought about history and treats his first novel as an important document in extricating his construct of the past. A close reading of the work reveals that it is an examination rather than a symptom of two powerful forces that dominate Baldwin's psychology, his father and his history.

James Baldwin felt the individual interpretation of one's experience is just as important as the experience itself. The novel is an informative exposition of how people interpret their experience and how that interpretation affects their psychology. Through Go Tell It on the Mountain Baldwin recreates the …

Separation Of Church And State: A Diffusion Of Reason And Religion., Patricia Annettee Greenlee

Electronic Theses and Dissertations

The evolution of America's religious liberty was birthed by a separate church and state. As America strides into the twenty first century the origin of separation of church and state continues to be a heated topic of debate. Conservatives argue that America's version of separation of church and state was birthed by principles of Christian liberty. Liberals reject this idea maintaining that the evolution of a separate church and state in America was based on enlightened thinking that demanded rational men should have religious liberty. The best way to achieve this was by erecting a wall of separation between church …

Product Placement During The Family-Viewing Hour., Harry C. Arnold

Electronic Theses and Dissertations

The so-called family-viewing hour, the eight to nine o’clock hour of prime time, is one of the most watched hours of television by both adults and children. Advertisers, of course, favor shows that draw large audiences so their product presentations or commercials are witnessed by masses of people. Now, because of videocassette recorders and other similar control devices, viewers are eliminating commercials from their viewing experience¹ and advertisers are clamoring for new ways to get their products into the mind of the consumer.² To counteract this commercial avoidance by consumers, advertisers are embedding products within television programming thereby …

Polyaniline And Its Derivatives For Environmental Analysis., Atogho Jude Abia

Electronic Theses and Dissertations

Electrooxidation has been used to deposit thin film polyaniline as well as its derivative - thin film poly (ortho-phenylenediamine) (POPD) and poly (meta-phenylenediamine) (PMPD) on carbon electrodes, which are subsequently used to monitor the environmental heavy metal ions (Hg²⁺, Pb²⁺ ,Cd²⁺) through a rather unusual "blocking" of anodic stripping for these metals. Using Hg²⁺ as a model, its cyclic voltammogram for a modified glassy carbon electrode with the resultant polymer shows an enhanced cathodic peak that increases linearly with the analyte ion concentration. POPD also exhibits unique selective detection for organic species. Acetaminophen and …

Particle Size Reduction Of Phthalocyanine Blue Pigment., Robert Ian Mcdowell 1981-

Electronic Theses and Dissertations

In a printing ink plant, phthalocyanine (Pc) aqueous slurries are produced by grinding the Pc pigment in water using a media mill. Mostly, dispersions of Pc in water are used in heat-set printing inks to make the color phthalo blue. Typically, Pc slurries are 40-50% solids and ground with steel media (spherical beads) to produce a stabilized dispersion with 99.9 percent of all solid particles less than 0.5 microns in size. Vertical media mills have been the industry norm; however, in producing submicron particle sizes, the efficiency is less than that of newer horizontal media mills that feature high internal …

Electronic Theses and Dissertations

For many years the concept of Lean Manufacturing has been applied in automotive development as a tool to refine the manufacturing practices to the greatest efficiency possible through waste reduction. Continuous Improvement is a quality innovation process that supports this objective, based on the manufacturing pillar – work processes and scientific experiments must be controlled and constantly modified and improved by the people who do, and are accountable for the work. Continuous Improvement implicitly implies the understanding and recognition of what is a problem and problem solving techniques used to formulate the best countermeasures to those problems. The process of …

Using Auditory Evoked Brain Responses To Detect Anxious Vulnerabilities In Neonates., Kyle William Harvison

Electronic Theses and Dissertations

Anxiety disorders are prevalent in both adult and child populations, and are associated with significant economic and psychosocial costs. There are clearly familial patterns of transmission within the anxiety disorders, and the inherited risk is likely a non-specific vulnerability toward negative affect, with a biological-environmental interaction leading to specific manifestations within the anxiety disorders. Among the vulnerabilities toward anxiety may be information processing biases that predispose individuals to be more vigilant to novelty, processes that may be specifically associated with the right cerebral hemisphere. The current study utilized auditory event related potentials (ERPs) to explore the degree to which such …
