Consistent application of dialectical materialism leads Marxism-Leninism to the assertion that matter is infinite in its properties. However, the history of physics shows that the various levels of matter possess geometric dimensions that originate at the lowest level and continue through the others. The search for absolute natural constants -- which Planck called the most pleasant task of physics -- shows the conviction of the physicists that there is a limit to the parameters, a limit beyond which matter is no (...) longer divisible.

A pO -algebra $${(L; f, \, ^{\star})}$$ is an algebra in which ( L ; f ) is an Ockham algebra, $${(L; \, ^{\star})}$$ is a p -algebra, and the unary operations f and $${^{\star}}$$ commute. Here we consider the endomorphism monoid of such an algebra. If $${(L; f, \, ^{\star})}$$ is a subdirectly irreducible pK 1,1 - algebra then every endomorphism $${\vartheta}$$ is a monomorphism or $${\vartheta^3 = \vartheta}$$ . When L is finite the endomorphism monoid of L is (...) regular, and we determine precisely when it is a Clifford monoid. (shrink)

The Database on Ethics Related Legislation and Guidelines was launched in March 2007 as the fourth database of the UNESCO Global Ethics Observatory system of databases in ethics of science and technology. The database offers a collection of legal instruments searchable by region, country, bioethical themes, legal categories and applicability to specific articles of the UNESCO Universal Declaration on Bioethics and Human Rights and International Declaration on Human Genetic Data. This paper discusses the background and rationale for the database and (...) its role as a consultative and comparative resource hub for the study of ethics related legal instruments across the world, with the purpose of informing and inspiring relevant stakeholders on the implementation of the principles contained within the UNESCO declarations on bioethics.

This essay is a critique of medical/clinical ethics from the personal perspective of a medical historian in an academic health science centre who has interacted with ethicists. It calls for greater transparency and accountability of ethicists involved in ‘bedside consulting;’ it questions the wisdom of the four principles of biomedical ethics and their American cultural origins with respect to training; challenges the authority of ‘core competencies’ for ethicists as identified by the American Society for Bioethics and Humanities; and muses over (...) the apparent reintroduction of religion into clinical medicine through the medium of bioethics. This essay is designed to provoke reflection on the putative ‘professionalism’ of the consulting ethics enterprise for which educational baselines and curricula are not standardized. By analysing sources such as the professional material communicated by the Canadian Bioethics Society, it also critiques the collective ethical shortcoming... (shrink)
