Dog Training - Love or Corrections?

Can't help myself today, I'm enjoying being the asker! lol

So let's hear it.

What is going to more effectively train your dog?
Showing your dog love or providing corrections?
In either case, why do you believe this is the correct method?
Update: I understand that people can give love and affection when they are not misbehaving.

Please read the question carefully - this pertains to training ONLY.
The closest thing to "affection" my dog gets during training session is quiet verbal praise when he is doing something correctly.
Update 2: @Chigirl - I'm glad I could help lol
