A Closer Look at Salish Intransitive/Transitive Alternations

A Closer Look at Preduction

In a recent paper Jun Arima formalises the idea of preduc-tion { a non-monotonic schema providing a common basis for inductive and analogical reasoning. We examine some of the implications of this schema, as well as its connections with prototypes and conceptual spaces. A generalised version of his schema is motivated and developed to address diiculties with asymmetry and disjuncts.

A Closer Look at HMAC

Bellare, Canetti and Krawczyk [BCK96] show that cascading an ε-secure (fixed input length) PRF gives an O(εnq)-secure (variable input length) PRF when making at most q prefix-free queries of length n blocks. We observe that this translates to the same bound for NMAC (which is the cascade without the prefix-free requirement but an additional application of the PRF at the end), and give a matchin...

A Closer Look at Trumping1

According to Schaffer (2000a), “trumping preemption” is a category of redundant causation distinct from early and late preemption and from overdetermination. I show that the putative causal difference between causal processes in cases thought to be trumping preemption generates early preemption or overdetermination rather than trumping. I draw a novel lesson from cases thought to be trumping: t...

A closer look at the elementary fermions.

Although there have been many experimental and theoretical efforts to measure and interpret small deviations from the standard model of particle physics, the gap that the model leaves in understanding why there are only three generations of the elementary fermions, with hierarchical masses, has not received the attention it deserves. I present here an attempt to fill this gap. Although our find...
