What Is a Reasonable Argumentation Semantics?

In view of the plethora of different argumentation semantics, we consider the question what the essential properties of a “reasonable” semantics are. We discuss three attempts of such a characterization, based on computational complexity, logical expressivity and invariance under partial duplication, which are satisfied by most, if not all, known semantics. We then challenge each of these propo...

What ‘ shape ’ is space - time ?

Some examples from the mathematics of shape are presented that question some of the almost hidden assumptions behind results on limiting behaviour of finitary approximations to space-time. These are presented so as to focus attention on the observational problem of refinement and suggest the necessity for an alternative theory of 'fractafolds' against which the limiting theory of C ∞-differenti...

P-value: What is and what is not

The misinterpretation and misuse of p-value have been increasing for decades. In March 2016, the American Statistical Association released a statement to warn about the use and interpretation of p-value. In this study, we provided a definition and discussion of p-value and emphasized the importance of its accurate interpretation.
