perverse formative » experience formative (Expand search)
formative process » formation process (Expand search), creative process (Expand search)
decrease not » decrease akt (Expand search), decrease on (Expand search), decrease or (Expand search)
not perverse » not reverse (Expand search), of perverse (Expand search), to perverse (Expand search)
decrease of » decrease in (Expand search)
of decrease » or decrease (Expand search), not decrease (Expand search), to decrease (Expand search)
decrease at » decrease akt (Expand search), decrease and (Expand search), decrease in (Expand search)

You may be able to get more results by adjusting your search query.

• If you are trying to use Boolean operators, they must be ALL CAPS: (( decrease NOT perverse formative process ) OR ( decrease of decrease at decrease ))~.
• The words AND, OR and NOT may confuse the search; try adding quotes: "(( decrease not perverse formative process ) OR ( decrease of decrease at decrease ))~".
• Adding a wildcard symbol may retrieve word variants: (( decrease not perverse formative process ) OR ( decrease of decrease at decrease ))*.
