Reasoning with hypothetical cases helps decision-makers evaluate alternate hypotheses for deciding a case. The hypotheticals demonstrate the sensitivity of a hypothesis to apparently small factual differences that may require different results because they shift the tradeoffs among conflicting underlying principles. By anticipating variations, the decision-maker seeks to formulate as general an...

I outline an interpretive theory of vagueness, emphasizing its advantages as a theory of language in use, compatibility with the data of descriptive linguistics, and its explanation for the interest-relativity of vagueness.

OpenGL is the industry-leading, cross-platform graphics application programming interface (API), and the only major API with support for virtually all operating systems. Many languages, such as Fortran, Java, Tcl/Tk, and Python, have OpenGL bindings to take advantage of OpenGL visualization power. In this article, we present Ch OpenGL Toolkit, a truly platform-independent Ch binding to OpenGL f...

The survival of any organization depends upon its competitive edge. Even though Lean is one of the most powerful quality improvement methodologies, nearly two-thirds of the Lean implementations results in failures and less than one-fifth of those implemented have sustained results. One of the most significant tasks of top management is to identify, understand and deploy the significant Lean pra...

We apply topic modeling to classifying the genre of Ghazal, a form common in Persian poetry. We show that a classifier based on automatically-generated topics exposes important information with only a small performance penalty: the top discriminative topics can be manually aligned with themes prevalent in the associated genres, as identified by scholars of literature. We also weigh in on a long...
