This had been done by revising a pamphlet explaining the code of conduct to students to "more explicitly" inform them of the types of behaviour the university was concerned about.
"Even though [these behaviours] have always been in the code, if we were to say 'we are just going to enforce it more' the students could feel that is rather unfair.
"So, what we are saying is that you will be held to account, regardless of whether you have done this before, or whether you see it as a change."
Asked to respond to students who believed the university had gone too far and was eroding "scarfie culture", she said: "The university hasn't suggested that students shouldn't drink at all and if they think the university has gone too far, they should go to a university somewhere else."
"All we are asking is that students abide by the code of conduct. It's very simple. I don't think there are many students... who would argue that the code of conduct isn't fair, particularly when they are sober."
She was also keen to remind students the university had their best interests at heart.
The effort to see a culture change involved everybody and not just students, she said.
This could be seen in a discussion point in the action plan, which questioned whether the university should be "more directive" about the amount of alcohol consumed at departmental camps.
Other measures discussed in the plan included making student behaviour at bars and restaurants governed by the code of conduct, increasing the number of students who take part in online screening for alcohol problems and co-operating with other organisations, such as the council and police, in trying to improve drinking culture. Prof Connor said improved behaviour during this year's Orientation Week showed the university's efforts could be working, but emphasised it was not being "complacent".
"I don't think we have won the battle - if it is a battle. It's a continual, gradual process."
