With lost credibility, ratings, and circulation, journalism faces a crisis of conscience. One answer is participatory community journalism; journalists become activists on behalfofthe process of self-government. A veteran journalist and author of Agents of Power, Altschull questions the press's arrogance, its faith in objectivity, and its unvarying insistence on its First Amendment rights, and asks instead that the public interest be put ahead of the maximization of profit, that media help to mediate public issues, and that the public be allowed (...) to play a bigger role in the news decision making process.

Evidence is summarized which indicates that the DNA loop anchoring proteins in chromosomes are effectively heterodimers that stack and are fastened into a bilaterally symmetrical array along the chromonemal axis. The evidence consists primarily of the observations made twenty five to thirty years ago on the pattern of sister chromatid exchanges and the way the DNA chains are sorted in the formation of diplochromosomes in cells that have undergone endoreduplication. The evidence indicates that each chain of DNA in the single (...) duplex, which is assumed to run the length of a chromosome, is anchored to a bilaterally symmetrical axis of heterodimers that sort the two original chains among the four derived chromatids of each diplochromosome in a very precise way. These observations are considered in the context of investigations on the nature of scaffold proteins and the loop anchorage sequences, as well as the advances being made on the nature of DNA binding proteins and the roles of topoisomerase II.

Multiple accounts of how theories of human psychology and of image-making influenced each other in a decisive period in the history of philosophy and art.

In this paper certain basic assumptions about causation will be made explicit and then an attempt will be made to show, on the basis of those assumptions, that causation must be supplemented by an extra-causal operation of a selective nature. It is hoped that our assumptions will have in their own right a certain general acceptability, but since assumptions or “postulate sets”, whether antecedently acceptable or not are usually chosen for the purpose of proving something already deemed desirable, a word (...) should be said as to why it was thought desirable to argue for selectivity.

The mind as a whole escapes objective studies because belief in mind- independent reality is self-contradictory and by definition excludes subjective experience (awareness, 'consciousness') from reality. The mind's center therefore vanishes in studies which imply exclusive objectivism or empiricism. This conceptual difficulty can be counteracted by acknowledging that all mental and world structures arise within an unstructured origin- and-matrix for knowledge-structures and beliefs. The mind's structure is thus at the center of reality. Use of such a zero-structure reference can also (...) help to clarify some related conceptual difficulties and to bridge the gap between the 'two cultures'. (shrink)

This essay examines the effects of a change from traditional to working ontology on some conceptual problems that are under discussion in the literature : the liar paradox, the announced surprise paradox, the measurement problem, and the uncertainty relation. Some aspects of these puzzles appear to be by-products of the use of traditional ontology - as it is implied, for instance, in naïve realism - where conceptual tools have a (mind-independent) life of their own. Considering (in working ontology) what people (...) can actually do with the conceptual tools they have facilitates the access to these puzzles. (shrink)

Here is a simple, clear, useful proof that quantum mechanics contradicts Einstein, Podolsky, and Rosen's local realistic assumptions. It is a variant of the powerful argument first worked out by Daniel Mordechai Greenberger, Michael A. Horne, and Anton Zeilinger. This version uses the eigenstates of two orthogonal spin components for three spin-1/2 particles. No operator or matrix algebra is necessary. A novel discussion of the background and history serves to introduce this proof and to place it in the context of (...) Danny's work. (shrink)

A Boolean product construction is used to give examples of existentially closed algebras in the universal Horn class ISP generated by a universal classKof finitely subdirectly irreducible algebras such that Γa has the Fraser-Horn property. If ⟦a≠b⟧ ∩ ⟦c≠d⟧ = ∅ is definable inKandKhas a model companion ofK-simple algebras, then it is shown that ISP has a model companion. Conversely, a sufficient condition is given for ISP to have no model companion.
