RE: &&

&& and 'and' have different precendence that's the only difference, but in
your case it doesn't matter.

what exactly are you trying to do? Your code reads

if @dates has data 
	and the other two BOTH do not have data 
then do somthing with @dates

else if the above is false and 
	@dates has no data and
	@themes does have data AND
	@cities doesn't have data
then do something with themes.
