Animal Contribution to Human Medicine

Description: The use of animal models in research has led to a fierce debate between animal rights activists and scientists. The former claim that little useful information is gained from animal studies and the suffering of animals does not preclude any treatments which may be used to treat human illnesses. Yet, research scientists claim that in vivo animal models are of absolute necessity to developing treatments and cures to disease. To determine the necessity of animal use, one must examine the models c… more

Anne Brontë's New Women: Agnes Grey and The Tenant of Wildfell Hall as Precursors of New Woman Fiction

Description: Anne Brontë's Agnes Grey and The Tenant of Wildfell Hall were published more than forty years before the appearance of the feminist type that the Victorians called the “New Woman;” yet, both novels contain characteristics of New Woman fiction. By considering how Brontë's novels foreshadow New Woman fiction, the reader of these novels can re-enact the “gentlest” Brontë as an influential feminist whose ideology informed the construction of the radical New Woman. Brontë, like the New Woman writ… more

The Apologist Tradition: A Transitional Period in Southern Proslavery Thought, 1831-1845

Description: Early antebellum defenders of slavery acknowledged that slavery created problems for southern society. They contended, however, that slave society was better and more natural than other forms of social organization. Thomas R. Dew, William Harper, and James Henry Hammond each expressed a social philosophy in which slavery had a crucial role in preserving social order. They argued from the basis of social organicism, the idea that society should have an elite that controlled the masses. For all t… more

Asserting Identity in Wagner's Shadow: The Case of Engelbert Humperdinck's Königskinder (1897)

Description: Engelbert Humperdinck (1854-1921), who was considered a Wagnerian due to to his past work in Bayreuth and the Wagnerian traits of his Hänsel und Gretel, seems to have believed that to define himself as a composer, he had to engage somehow with that designation, whether through orthodox Wagner imitation or an assertion of his independence from Wagner's musical legacy. The latter kind of engagement can be seen in Humperdinck's Königskinder (1897), in which he developed a new kind of declamatory … more

Automated Defense Against Worm Propagation.

Description: Worms have caused significant destruction over the last few years. Network security elements such as firewalls, IDS, etc have been ineffective against worms. Some worms are so fast that a manual intervention is not possible. This brings in the need for a stronger security architecture which can automatically react to stop worm propagation. The method has to be signature independent so that it can stop new worms. In this thesis, an automated defense system (ADS) is developed to automate defense… more
