Hooliganism can be a problem at ice hockey matches. Two students at Blekinge Technical College spent the autumn analysing Karlskrona Hockey Club, and say that a smile and a free hot dog could do a lot of good.
The researchers, Markus Höglund and Mikael Ljungqvist Lavhammar, have focused on the standing area, where the away-fans are.
Some of the ideas that they're proposing include better lighting when away-fans are in town, meeting and greeting, and match stewards who watch the crowd, not the match.
They sent a survey out to all of the supporter organisations linked to the top Swedish hockey clubs. Mikael Ljungqvist Lavhammar says that one thing has been clear form the answers.
"They want to be treated with respect, and have the same freedom and opportunities as the home crowd."
The head of the Karlskrona Hockey Klub says that they two students have come up with a clever suggestion to solve the problem of how to get surveillance cameras into the arena.
"We have been thinking about cameras, and then these two come and ask, why haven't we been using cameras from mobile phones? I mean, why haven't we thought of this before?" says club boss Mats Johansson. The idea would be for one of the stewards to start filming with a phone, if a fight broke out.
One of the issues they have been looking at is how to deal with fans' frustration, when their club loses.
Researcher Marcus Höglund says that they think it might be a good idea to take an idea from one of Sweden's most famous companies.
"At Ikea you can buy a cheap hotdog, and everything feels ok. So we wondered whether we couldn't do something similar at a hockey match. I mean, who wouldn't be happy, to get a free hot dog on the way to the bus?"
The head of Karlskrona club says that they may very well be using some of these ideas.
