Authoritative And Unbiased Responses To Geographic Queries, Naresh Adhikari May 2020

Authoritative And Unbiased Responses To Geographic Queries, Naresh Adhikari

Theses and Dissertations

Trust in information systems stem from two key properties of responses to queries regarding the state of the system, viz., i) authoritativeness, and ii) unbiasedness. That the response is authoritative implies that i) the provider (source) of the response, and ii) the chain of delegations through which the provider obtained the authority to respond, can be verified. The property of unbiasedness implies that no system data relevant to the query is deliberately or accidentally suppressed. The need for guaranteeing these two important properties stem from the impracticality for the verifier to exhaustively verify the correctness of every system process, and …

"Swamp Thing: Alligators, Symbolism, And The Meaning Of Animals In The American South, Nathan Drake May 2020

"Swamp Thing: Alligators, Symbolism, And The Meaning Of Animals In The American South, Nathan Drake

Theses and Dissertations

Humans form lasting and unique relationships with the natural world and, by extension, the organisms and animals who have for millennia carved out niche environments. Scholars and general observers agree—at least in principle—that human beings have actively shaped (for better and for worse) the habitats, behaviors, and population of the Earth’s creatures. In turn, those spaces and animals have influenced not only how humans think of the natural world, but also of humanity itself. Animals, in other words, help humans understand themselves.1 This dissertation is a history of the American Alligator. A study of human interactions with alligators can reveal …
