Evolving power dynamics in an unconventional, powerless ethics committee

Power Politics and the Powerless

Unconventional protein secretion: an evolving mechanism.

The process by which proteins are secreted without entering the classical endoplasmic reticulum (ER)-Golgi complex pathway, in eukaryotic cells, is conveniently called unconventional protein secretion. Recent studies on one such protein called Acb1 have revealed a number of components involved in its secretion. Interestingly, conditions that promote the secretion of Acb1 trigger the biogenesis ...

Renormalising Nn Scattering: Is Power Counting Powerless?

The renormalisation of NN scattering in theories with zero-range interactions is examined using a cut-off regularisation where the cut-off is taken to infinity, dimensional regularisation (DR) with minimal subtraction, and DR with powerdivergence subtraction. In the infinite cut-off limit power counting breaks down: terms of different orders in the potential contribute to the scattering amplitu...

Ethics-committee authorization in Germany.

On 9 August 1994 the German legislature revised the German Drug Law (AMG). Included in the revision is a passage requiring, for the first time, that the sponsors and investigators of clinical studies involving human subjects first obtain the approval of an ethics committee before carrying out such studies. According to the legislation, which takes effect on 17 August 1995, approval is to come f...

Dynamics in an Evolving Partnership

Repeat players’ ability to cooperate in equilibrium depends on how long they expect their relationship to last (“stability”), which itself may change over time. This paper develops a theory of endogenous stability and dynamic performance in partnerships with evolving payoffs, in the context of a simple repeated Prisoners’ Dilemma with voluntary entry and exit. More stable partnerships are more ...
