The existence of consciousness in animals may have been overlooked. Continuity in consciousness between humans and animals is predicted by evolutionary theory. However, there are specific methodological difficulties associated with investigating such a phenomenon: it cannot be directly measured; animals, unlike humans, cannot directly tell us about their conscious experience; experiments which have made comparisons to human consciousness cannot detect consciousness of a different form; application of the law of parsimony in science has traditionally led to the conclusion that it (...) does not exist.

"We prove that any variety of relation algebras which contains an algebra with infinitely many elements below the identity, or which contains the full group relation algebra on some infinite group (or on arbitrarily large finite groups), must have an undecidable equational theory. Then we construct an embedding of the lattice of all subsets of the natural numbers into the lattice of varieties of relation algebras such that the variety correlated with a set [italic capital]X of natural numbers has a (...) decidable equational theory if and only if [italic capital]X is a decidable (i.e., recursive) set. Finally, we construct an example of an infinite, finitely generated, simple, representable relation algebra that has a decidable equational theory.'' -- Abstract. (shrink)

Summary One aim of this paper is to provide an assessment of the recent attempts to interpret the development of Galileo's theory of motion in the late Paduan period 1604?1610. In addition to this a new interpretation of this process of development is advanced. This interpretation is the first that proves able to provide a full account of all the features on folio 152r of volume 72 of the Galilean manuscripts which has been claimed to be of crucial significance. The (...) major feature of the interpretation is that it is the first to account for the relationship between Galileo's theoretical and experimental work in the period 1604?1610. (shrink)

Recent study of Galileo's surviving manuscript notes on motion has revealed that by 1609 he had developed the major part of his theory of projectile motion. During the period of these theoretical advances Galileo was engaged in important related experimental investigations; this has become clear from the study of folios 114r and 116v of the manuscript on motion. This paper provides an interpretation of a manuscript not previously discussed—folio 81r. The analysis provided indicates that it is evidence of an important (...) early experiment of the series in which Galileo studied the projectile trajectory. The reconstruction of the experiment concerned reveals relationships with the enquiries suggested by folio 114r and 116v and indicates that Galileo examined the form of projectile trajectories with some care.

Properties sometimes attributed to the “particle” aspect of a neutron, e.g., mass and magnetic moment, cannot straightforwardly be regarded in the Bohm interpretation of quantum mechanics as localized at the hypothetical position of the particle. This is shown by examining a series of effects in neutron interferometry. A related thought-experiment also provides a variation of a recent demonstration that which-way detectors can appear to behave anomolously in the Bohm theory.

Objective Recent legislation mandating the inclusion of children in clinical trials has resulted in an increase in the number of children participating in research. We reviewed the literature regarding the reasons parents chose to accept or decline an invitation to enrol their children in clinical research. Methods We searched for qualitative studies, written in the English language that considered the experiences of parents who had been invited to enrol their children in research. SCOPUS and Web of Knowledge electronic databases and (...) reference lists of retrieved articles and review papers were searched. Retrieved articles were synthesised using the narrative synthesis method. Results 16 qualitative studies exploring the experiences of parents living in five countries whose children had a range of health conditions of varying severity were included. The health status of the child appeared to influence parents' reasons for participation. Parents whose children had life threatening conditions often considered they had no choice but to participate and many welcomed the innovation offered through research participation. Such parents also viewed the risks of research less negatively than those whose children were healthy or in the stable stage of a chronic condition. This raises questions regarding the voluntariness of informed consent by such parents. Conclusions A tailored approach is needed when discussing research participation with parents of eligible children. While parents of healthy children may be more open to discussions of altruism, those whose children have life threatening illnesses should be given adequate information about the alternatives to, and risks of, research participation.
