It is because of their help and support that I have managed to write this PhD thesis. I got a lot of inspiration, discussion and support from many people throughout this process and I owe thanks to many wonderful people. Let me first give you a mental image of what it feels like to do a PhD. Doing a PhD can feel like hiking up a difficult mountain. It is tough at times, challenging, and sometimes the heights can seem scary. In the beginning you still have lots of energy; it is exciting and you want to run up the whole mountain. But then you are still below the tree border and it is more like a walk up a steep hill. But as you move on it gets trickier, and you have to follow a path and not just aimlessly run through the woods. If it is a really difficult mountain, like Großglockner, the highest mountain in Austria, or even a Himalayan mountain, you will need a guide to help you up. Hiking alone is not much fun, anyhow; it is more enjoyable to walk with people who also cheer you on when you get tired and just want to give up or take a long break. On my PhD mountain hike, sometimes I was exhausted and did not want to continue. Sometimes I got scared of heights and needed support. Sometimes I did not know which path to follow, as on the PhD mountain there are no markings to show the way; you have to find your own safe way up. But there are people guiding you, supporting you and sharing their experiences and knowledge about which way seems safest. Fortunately, I had many guides and safety tools that helped me complete my journey up the mountain safely. First, I have to thank the municipal housing company Stångåstaden in Linköping for their collaboration work within the CAREER project; this made it possible for me to write this PhD thesis. Thank you for opening your doors to us. We enjoyed coming to your headquarters, not only due to the great hotel breakfasts
