The problem of how the brain produces consciousness, subjectivity and "something it is like to be" remains one of the greatest challenges to a complete science of the natural world. While various scientists and philosophers approach the problem from their own unique perspectives and in the terms of their own respective fields, Biophysics of Consciousness: A Foundational Approach attempts a consilience across disparate disciplines to explain how it is possible that an objective brain produces subjective experience. This volume unites the (...) cr me de la cr me of physicists, neuroscientists, and psychiatrists in the attempt to understand consciousness through a foundational approach encompassing ontological, evolutionary, neurobiological, and Freudian interpretations with the focus on conscious phenomena occurring in the brain. By integrating the perspectives of these diverse disciplines with the latest research and theories on the biophysics of the brain, the book tries to explain how what John Searle calls a "conscious field" can be an adaptive and causal element in the natural world.

Recent studies showing that pontine burst cells carry a monocular code for rapid eye movements raise questions about the organisation of signals at more central levels. Evidence that the superior colliculus may also be involved in the coding of movements in depth is reviewed. Recent work showing that the global effect is a property of refixations in 3-D space is another indication that the oculomotor systems for direction and depth are centrally coupled.

This is a periodic table explicitly for chemists rather than physicists. It is derived from Newlands’ columns. It solves many problems such as the positions of hydrogen, helium, beryllium, zinc and the lanthanoids but all within a succinct format.

Products of particlelike representations of the homogeneous Lorentz group are used to construct the degrees of spin angular momentum of a composite system of protons and neutrons. If a canonical labeling system is adopted for each state, a shell structure emerges. Furthermore the use of the Dirac ring ensures that the spin is characterized by half-angles in accord with the neutron-rotation experiment. It is possible to construct a Clebsch-Gordan decomposition to reduce a state of complex angular momentum into simpler states (...) which can be identified with α and β particles, multipole operators, etc. Finally, ground-state energy levels are calculated for all the even-even nuclei by using a differentiable manifold that is spin-graded and gauge-invariant by construction. It is shown that this manifold is Grassmann. (shrink)

This is a summary of “Toward a Global Media Ethics: Theoretical Perspectives,” which appeared in Ecquid Novi: African Journalism Studies , 29(2), 2008, 135-172. The article was written by Clifford G. Christians, University of Illinois at Urbana-Champaign; Shakuntala Rao, State University of New York-Plattsburgh; Stephen J. A. Ward, University of Wisconsin-Madison; and Herman Wasserman, University of Sheffield. It was the result of a workshop on global media ethics by the article's authors hosted by the Stellenbosch Institute for Advanced Study (STIAS) (...) at the University of Stellenbosch, South Africa. The authors brought to the discussion the different perspectives of contractualism, communitarianism, and critical theory. The intention of the summary is to the draw the attention of scholars and ethicists outside the readership of Ecquid Novi to this leading-edge theoretical work. It is hoped the summary will stimulate comment and further work in global media ethics. The summary is not intended to replace the original article. Readers should consult the original for the full argument. (shrink)
