Silencing science: partisanship and the career of a publication disputing the dangers of secondhand smoke
This paper examines the silencing of science, that is, efforts to prevent the making of specific scientific claims in any or all of the arenas in which these claims are typically reported or circulated. Those trying to mute the reporting or circulation of scientific claims are termed “partisans.” The paper examines silencing through a systematic examination of the “rapid responses” to a smoking study published in the British Medical Journal claiming that secondhand smoke is not as dangerous as conventionally believed. Media coverage of the smoking study is also examined, as is the question of whether there is self-silencing by the media regarding doubts about the negative effects of passive smoke. The results suggest that the public consensus about the negative effects of passive smoke is so strong that it has become part of a regime of truth that cannot be intelligibly questioned.
Generalizing earlier results on dust collapse in higher dimensions, we show here that cosmic censorship can be restored in some classes of gravitational collapse models with tangential pressure present, if we take the spacetime dimension to be $N\ensuremath{\ge}6$. This is under conditions to be motivated physically, such as smoothness of initial data from which the collapse develops. The models considered here with nonzero pressure include the Einstein cluster spacetimes which have been earlier studied extensively. Our work provides a step towards an understanding of the cosmic censorship conjecture and the necessary conditions for its validity.
