Baker's highly influential and widely cited studies suggest that people are capable of non-visual navigational performance comparable to that of homing pigeons. Past failures to replicate this work have been attributed by Baker to geomagnetic influences. We report a series of experiments in which both temporal and spatial geomagnetic controls were introduced. We could still find no evidence for...

Home equity conversion for the elderly is a means for elderly homeowners to draw down a portion of their accumulated wealth without having to sell their homes and/or move. The instruments to convert equity have substantial promise for matching the expenditure needs associated with long-term care services. There have been no formal attempts to pair these potential revenues and expenditures, but ...

Data from a 1997 nationwide telephone survey are used to assess the relationship between choice and public opinion about managed care. We found that only a minority of the working-age population effectively control what health plan they get. Persons without choice were markedly more dissatisfied with their health plan, especially when enrolled in managed care. In multivariate analysis, how resp...

Using a method of R. McKenzie, we construct a finitely generated semisimple variety of infinite type, and a finitely generated nonsemisimple variety of finite type, both having arbitrarily large finite but no infinite simple members. This amplifies M. Valeriote’s negative solution to Problem 11 from [1]. R. McKenzie [2] has constructed a finitely generated variety having arbitrarily large finit...

The totality of 4X4 matrices with coefficients in GF [22], determinant unity, and which permute among themselves the vectors of dimension 4 having 4 co-ordinates nonzero marks of GF [22], or 2 zeros and 2 nonzero marks of the field, forms a simple [l, p. 285, problem 9, part (4)]1 (multiplicative) group, G, of order 26-34-5. It will be demonstrated that G is isomorphic with no multiply transiti...

Recently in epistemology a number of authors have mounted Bayesian objections to dogmatism. These objections depend on a Bayesian principle of evidential confirmation: Evidence E confirms hypothesis H just in case Pr(H|E)>Pr(H). I argue using Keynes’ and Knight’s distinction between risk and uncertainty that the Bayesian principle fails to accommodate the intuitive notion of having no reason to...

It is proved that, for any prime power q; a 3-connected matroid with no U3;6-minor has at most ðq 2Þ! inequivalent representations over GFðqÞ: r 2004 Elsevier Inc. All rights reserved.
