New reals: Can live with them, can live without them

Judah and Shelah [3] proved that countable support iterations of proper forcings preserve the ω-bounding property (see 2.2 here). In his book Proper and Improper Forcing [8, XVIII §3] Shelah gave several cases of general preservation theorems for proper countable support iterations (the proofs tend to be hard to digest, though). In this paper we deal with “Case A”. A simplified version of this ...

Let them cheat!

We consider the problem of fairly allocating a bundle of infinitely divisible goods among a group of agents with “classical” preferences. We propose to measure an agent’s “sacrifice” at an allocation by the size of the set of feasible bundles that the agent prefers to her consumption. As a solution, we select the allocations at which sacrifices are equal across agents and this common sacrifice ...

New Reals: Can Live with Them, Can Live without Them (draft)

A simplified version of this case appeared in Section 5 of Goldstern’s Tools for your forcing constructions [2]. This version uses the additional requirement that every forcing of the iteration adds a new real. Note that this requirement is met in most applications, but the case of forcings not adding reals has important applications as well (and not adding reals is generaly not preserved under...

Antidepressants: can't live with them, can't live without them.

A new wave of meta-analyses suggests that antidepressants are no better than placebo for major depressive disorder (MDD), and therefore, antidepressants not only don't work, but even worse, they harm patients because of the risk of adverse effects. The authors analyzed data from all antidepressant studies submitted to the Food and Drug Administration for registration (including failed studies w...
