For example, if it is now the case that Obama was born in 1961, it will never be the case that he was not born in 1961. A semantic consequence of this view is the following: (TP) Context-insensitive, temporally specific sentences about the past are truth-value-persistent ...

Editorial for ECAP, July Issue 2010 [PDF]
European Child & Adolescent Psychiatry, 2010 More and more studies deal with the problem of gene 9 environment interaction (G 9 E) to explain the origins and courses of child psychiatric disorders [3]. However, this kind of knowledge is still in its infancy and few of these G 9 E effects have been sufficiently replicated [8]. Nevertheless, the results can and should be introduced already in today’
