From Doubt To Its Social Articulation

From Acoustics to Articulation

The focus of this thesis is the relationship between the articulation of speech and the acoustics of produced speech. There are several problems that are encountered in understanding this relationship, given the non-linearity, variance and non-uniqueness in the mapping, as well as the differences that exist in the size and shape of the articulators, and consequently the acoustics, for different...

1 From certainty to doubt in fishery science

Fishery science is usually perceived by its practitioners as being a critical and quantitative activity, deeply dependent on mathematical analysis; indeed, the introduction to a well-known text on fisheries science suggests that only those who are comfortable writing computer programs or playing with numbers should become involved in fisheries management. This blunt statement demonstrates what ...

Defeasible inheritance with doubt index and its axiomatic characterization

This article introduces and uses a representation of defeasible inheritance networks where links in the network are viewed as propositions, and where defeasible links are tagged with a quantitative indication of the proportion of exceptions, called the doubt index. This doubt index is used for restricting the length of the chains of inference. The representation also introduces the use of defea...

Beyond Reasonable Doubt: Evolution from DNA Sequences

We demonstrate quantitatively that, as predicted by evolutionary theory, sequences of homologous proteins from different species converge as we go further and further back in time. The converse, a non-evolutionary model can be expressed as probabilities, and the test works for chloroplast, nuclear and mitochondrial sequences, as well as for sequences that diverged at different time depths. Even...
