The Introductory Essay: Richard Wright's Covert Challenging of Jim Crowism and Uncle Tomism

Richard Wright’s introductory essay to his collection of short stories Uncle Tom's Children describes hidden forms of resistance against Jim Crowism and Uncle Tomism. The essay entitled The Ethics of Living Jim Crow: An Autobiographical Sketch relates Wright’s daily confrontations with Jim Crowism with a particular emphasis on his evasive actions, and his covert activities, such as silence, pla...

A speed-up of oblivious multi-head finite automata by cellular automata

In this paper, we present a parallel speed-up of a simple, yet significantly powerful, sequential model by cellular automata. The simulated model is called oblivious multi-head finite automata and is characterized by the fact that the trajectory of the heads only depends on the length of the input word. While the original k-head finite automaton works in time O(nk), its corresponding cellular a...

Head-coupled Stereo Display for Visualization in a Document Retrieval System using Associative Networks

The Document Explorer provides head-coupled stereoscpopic viewing of 3-d visual representations for document collections, associative term thesauri, and individual documents. This style of interface has been called "fish tank VR" and shown to be relatively effective for 3-d viewing and interaction tasks. The system also provides mechanisms to integrate query formulation across the visual repres...

Nudging by Shaming, Shaming by Nudging

In both developing and developed countries, health ministries closely examine use of so-called nudges to promote population health and welfare. Cass Sunstein and Richard Thaler, who developed the concept, define a nudge as “any aspect of the choice architecture that alters people’s behavior in a predictable way without forbidding any options or significantly changing their economic incentives. ...
