Stacking of untyped bonuses: Initiative

[Kinithin]

Do untyped bonuses stack? Specifically,

"you receive a bonus on initiative checks equal to 1/2 your wizard level (minimum +1)." (Divination specialisation)

"You get a +4 bonus on initiative checks." (Improved Initiative feat)

Different sources so yes in this case.
