The ethical treatment of cancer patientsparticipating in clinical trials requiresthat patients are well-informed about thepotential benefits and risks associated withparticipation. When patients enrolled in phaseI clinical trials report that their chance ofbenefit is very high, this is often taken as evidence of a failure of the informed consent process. We argue, however, that some simple themes from the philosophy of language may make such a conclusion less certain. First, the patient may receive conflicting statements from multiple speakers about the expected (...) outcome of the trial. Patients may be reporting the message they like best. Second, there is a potential problem of multivocality. Expressions of uncertainty of the frequency type can be confused with expressionsof uncertainty of the belief type. Patients may be informed using frequency-type statements and respond using belief-type statements. Third, each speech episode involving the investigator and the patient regarding outcomes may subservemultiple speech acts, some of which may beindirect. For example, a patient reporting ahigh expected benefit may be reporting a beliefabout the future, reassuring family members,and/or attempting to improve his or her outcome by apublic assertion of optimism. These sources oflinguistic confusion should be considered injudging whether the patient's reported expectation isgrounds for a bioethical concern that there hasbeen a failure in the informed consent process.

The superfluid state of fermion-antifermion fields developed in our previous papers is generalized to include higher orbital and spin states. In addition to single-particle excitations, the system is capable of having real and virtual bound or quasibound composite excitations which are akin to bosons of spinJ P equal to0 −, 1−, 2+, etc. These pseudoscalar, vector, and tensor bosons can be massive or massless and provide the vehicles for strong, electromagnetic, weak, and gravitational interactions. The concept that the basic (unmanifest) (...) fermion-antifermion interaction can lead to a multiplicity of manifest interactions seems to provide a basis for a unified field theory. (shrink)

A new model for the aether is suggested according to which it is a superfluid state of fermion and antifermion pairs, describable by a macroscopic wave function. The vacuum state of this superfluid pervades the entire universe and may account for the missing matter. The visible matter in the universe appears as excitations from the underlying superfluid vacuum.

Children’s exposure to the marketing of energy-dense nutrient-poor (EDNP) foods is a public health concern and marketing investment is known to be shifting to non-broadcast media, such as the Internet. This paper examines the perceptions of parents and children on ethical aspects of food marketing to which children are exposed. The research used qualitative methods with parent-child (aged between 8–13 years), from South Australia. Thirteen parent-child pairs participated in this research. Ethical concerns raised by parents and children included, the marketing (...) of EDNP foods, pester power and family conflict and the use of powerful techniques via the Internet. Their views on rights and responsibilities represented a complex mixture of idealistic and pragmatic positions. They appeared to be caught within the tensions of problematizing unhealthy food marketing to children, both as a social problem and as an individual problem. Their dilemmas are not dissimilar to the broader policy debate in Australia on the matter of food marketing to children. The stale-mate on statutory regulations to protect children from exposure to EDNP food marketing could be advanced by stronger use of ethical arguments to protect children from harmful exploitation and to protect parents from forces that undermine their authority.

This collection of essays, presented to William Humbert Kane, O.P., founder of the Albertus Magnus Lyceum, has as its principle of unification the notion that the metaphysics and philosophy of nature of Aristotle, Albertus Magnus, and Thomas Aquinas relate directly and importantly--and more than historically--to modern science in all of its aspects. The general reader will probably find that several of the articles illumine for him aspects of the Aristotelian philosophy as much as they do aspects of modern science.--K. P. (...) F. (shrink)
