Eliminating the “concept” concept [PDF]

open access: yesBehavioral and Brain Sciences, 2010
AbstractMachery suggests that the concept of “concept” is too heterogeneous to serve as a “natural kind” for scientific explanation, so cognitive science should do without concepts. I second the suggestion and propose substituting, in place of concepts, inborn and acquired sensorimotor category-detectors and category-names combined into propositions ...

Fatal Relapse of Myelodysplastic Syndrome in a Patient with HIV/Hepatitis C Coinfection Treated with Simeprevir/Sofosbuvir

open access: yesJournal of the International Association of Providers of AIDS Care, 2017
Registrational studies and observational cohorts clearly suggest sustained virologic response (SVR) rates in HIV-/hepatitis C–coinfected patients are similar to monoinfected patients when utilizing interferon-free regimens, and this can be accomplished ...
