How to be a good Associate

I'm a senior analyst at an EB that has accepted an A2A promotion that will be starting over the summer. From the time I accepted the promotion, I was taken off of all of my analyst staffings and restaffed as an associate. I've been playing associate on deals and books with first year analysts working under me for the last few months.

I never minded working with hard-ass VPs and Associates and never took getting yelled at personally; however, I know that's not everyone, so I'm really trying not to be an asshole that yells and I always take them into a conference room if I'm providing constructive feedback so I don't embarrass them.

That being said, I feel like I'm not seeing the outcomes I'd like to see with this approach.

How do I motivate analysts to produce good work and act professionally at work without yelling at them and alienating myself. I've never had to motivate anyone other than myself before so this is new for me. Would love feedback from more senior folks as well as analysts.
