The development of ever smaller integrated circuits at the sub-micron and nanoscale—in accordance with Moore’s Law—drives the production of very small tags, smart cards, smart labels and sensors. Nanoelectronics and submicron technology supports surveillance technology which is practically invisible. I argue that one of the most urgent and immediate concerns associated with nanotechnology is privacy. Computing in the twenty-first century will not only be pervasive and ubiquitous, but also inconspicuous. If these features are not counteracted in design, they will facilitate (...) ubiquitous surveillance practices which are widely available, cheap, and intrusive. RFID technology is an instructive example of what nanotechnology has in store for privacy. (shrink)

Van den Belt recently examined the notion that synthetic biology and the creation of ‘artificial’ organisms are examples of scientists ‘playing God’. Here I respond to some of the issues he raises, including some of his comments on my previous discussions of the value of the term ‘life’ as a scientific concept.
The present discussion of sociobiological approaches to ethnic nepotism takes Pierre van den Berghe ʼs theory as a starting point. Two points, which have not been addressed in former analyses, are considered to be of particular importance. It is argued that the behavioral mechanism of ethnic nepotism—as understood by van den Berghe—cannot explain ethnic boundaries and attitudes. In addition, I show that van den Bergheʼs central premise concerning ethnic nepotism is in contradiction to Hamiltonʼs formula, the essential principle of kin (...) selection theory. It is further discussed how other approaches that make reference to ethnic nepotism are related to van den Bergheʼs account and its problems. I conclude with remarks on the evolutionary explanation of ethnic phenomena. (shrink)
We revisit the characterization of the Shapley value by van den Brink (Int J Game Theory, 2001, 30:309–319) via efficiency, the Null player axiom, and some fairness axiom. In particular, we show that this characterization also works within certain classes of TU games, including the classes of superadditive and of convex games. Further, we advocate some differential version of the marginality axiom (Young, Int J Game Theory, 1985, 14: 65–72), which turns out to be equivalent to the van den Brink (...) fairness axiom on large classes of games.

We use a new construction of an o-minimal structure, due to Lipshitz and Robinson, to answer a question of van den Dries regarding the relationship between arbitrary o-minimal expansions of real closed fields and structures over the real numbers. We write a first order sentence which is true in the Lipshitz-Robinson structure but fails in any possible interpretation over the field of real numbers.
L. van den Dries proved that the theory of n-valued rings has a model companion. We show here that this result is still true when the valuation rings are required to satisfy given inclusion relations (we restrict ourselves to the case of residual characteristic zero).
