The ontology of the "tractatus", In terms of which objects are characterized as propertyless simples, Is coherent provided wittgenstein is not mistakenly taken to be a constructive atomist building complexes from simples. A geometrical model is given to illustrate this. It is also shown that an ontology like that of the "tractus" removes much of the conceptual puzzlement of modern particle physics and has implications for current debates about realism, Possible worlds and rigid designators.

It is shown that the paradoxes of confirmation are closely linked to the paradoxes of material implication and that they can be avoided by formulating natural laws in terms of a genuine if-Connective rather than the material conditional. However, Natural laws so expressed are not confirmed by simple conjunctions. The question then is whether the common assumption that simple conjunctions do confirm universal generalizations is correct. The answer given is that it is not. In particular, A confirming proposition of the (...) form 'this is a black raven' is not equivalent to 'this is a raven and this is black'. (shrink)

It is shown that all those theses of traditional logic which were rejected by Russell in terms of a preferred interpretation of 'all' and 'some', in fact lead to inconsistency in any formal system of traditional logic satisfying certain minimal conditions. Hence, Russell's refutation is ultimately independent of his interpretation. Further, the derivation of each of the refutable theses depends crucially on the Bochenski/Lukasiewicz postulate 'Some _A are _A'. If this postulate is removed, the theses which remain are exactly those (...) which translate into theses of quantification theory. (shrink)

I want to pull together some well-known facts which, when taken together, provide us with a plausible, and I think persuasive, argument that Aristotle's logic is inconsistent. We cannot, of course, hope to show that it is formally inconsistent since he does not present us with a fully worked-out formal system. On the other hand, we do have Lukasiewicz's formal version of Aristotelian logic which he proves consistent. (edited).

The specialist field of intellectual disability nursing has been subjected to a number of changes since the move towards deinstitutionalisation from the 1970s. Government policies sought to change the nature of the disability workforce from what was labelled as a medicalised approach, towards a more socially oriented model of support. Decades on however, many nurses who specialise in the care of people with intellectual disability are still employed. In Australia, the advent of the National Disability Insurance Scheme offers an apt (...) moment to reflect upon these decades of specialised nursing care as the context of this nursing care will continue to evolve. A review of the published literature was conducted to explore what has shaped the field in the past and how this might inform the future of this speciality area under new policy and service contexts. People with intellectual disability have specific health and support needs that require a specialised workforce. Specialist nurses continue to be needed for people with intellectual disability.
