This paper introduces the idea of using the Dempster-Shafer theory of evidence with qualitative values. Dempster-Shafer theory is a formalism for reasoning under uncertainty which may be viewed as a generalisation of probability theory with special advantages in its treatment of ambiguous data and the ignorance arising from it. Here we are interested in applying the theory when the numbers that...

In this paper, we sharpen and generalize Shafer-Fink’s double inequality for the arc sine function.

I focus on the ethical non-naturalism of Russ Shafer-Landau. First, spend a good bit time specifying nature two versions naturalism and arguing that one is embraced ubiquitously—more importantly, should be embraced—by contemporary naturalists. do so because if am right about this, before we investigate details Shafer-Landau’s non-naturalism, there will significant burden proof for him to meet. ...

Recently, there has been renewed interest about incomplete security markets. Hart (1975) provided an example of nonexistence of competitive equilibria for incomplete real securities, which are claims to commodity bundles. Given this finding, Duffie and Shafer (1985, 1986a, b) prove generic existence of competitive equilibria of incomplete real security markets. Husseini et al. (1990) Geanakoplo...

Multi-classifier combination based on Dempster-Shafer theory of evidence has demonstrated it’s superior performance. In the approach based on Dempster-Shafer theory, the basic probability assignments for evidence are usually derived from classifiers’ global performance. However, our study discovered that while using classifiers’ global performance as basic probability assignments doesn’t necess...
