Lecturing, professional positions and memberships are all experience of some kind, though :-)
I think "sundry" also gives me this impression of the things being random and not massively important. If you just use a single word, "Other" at least drops the "random" suggestion.
sundry adj various; assorted; miscellaneous; several. noun (sundries) various small unspecified items; oddments. all and sundry everybody.
ETYMOLOGY: Anglo-Saxon syndrig. (Chembers)
sun•dry /sndri/ adj. [only before noun] (formal) various; not important enough to be named separately: a watch, a diary and sundry other items http://www.oup.com/oald-bin/web_getald7index1a.pl
