This study was done regarding whether sealing or ventilation is the best solution to prevent moisture on cold attics. The authors of this report addressed the problem with moisture in attics when they started their cooperation with Peab. The methods included interviews with people, database research, and calculations of a project in Akersberga north of Stockholm. The conclusion is based on interviews and other information as they are analyzed in relation to the house of reference. The focus of this report is on problems with moisture in the attics known as cold attics. The background of the problem with moisture is that today’s slabs are usually insulated to save energy and that the attics nearly gives the climate as the outdoor climate. The contribution of moisture increases this problem when the relative humidity reaches 75 %, which in most cases promotes mould. Moisture comes with natural ventilation through the eaves due to outside humidity and precipitation finding its way in, and at the same time comes from the inside through openings or cracks on concrete slabs, ventilation ducts, and attic doors. Moisture also comes into the attic from building materials, especially from the concrete slabs that evaporate which gives off a lot of moisture throughout the years. These things are possible to prevent with four different methods ventilation, sealing, heating or insulating the outer roof. Moisture effects are calculated from the examples given by Roxull FuktFakta in comparison with the authors own calculations from other databases. The object of reference, Bergahojden 6, is a residential building that has served as a model for all the calculations. The conclusion shows that air circulation has to increase to get out the moisture through the ventilation. The winters here in Sweden are so humid that the ventilation should be suitable enough so that the humidity does not rise above 75 % in the attic. To heat up the attic with devices, or by using roof insulation, would bring the same climate as the outdated slab insulations. There will be a big loss of energy with heat going out if the roof is not insulated. To apply both systems would be a double investment which would be hard to convince builders of. The conclusion is that the best method would be to combine sealing with ventilation, or a possible mechanical system which allows the attic to be ventilated during the summer and sealed during the winter.

This study is based on six semi-structured interviews with police officers regarding how humor is used by the police. The purpose of the study was to understand and explain how humor is being used between colleagues within the police force and how it is used towards the public. The aim is to gain a deeper understanding on how humor helps the police officers to handle the emotions that they encounter on a daily basis. We will also explain the moral boundaries for this social group and where the transgression for these gets too big. We explain these factors by analyzing them with the help of Goffmans (2020) Dramaturgical perspective and Hochschild’s (2003) research about emotional management.   In conclusion, the results of the interviews showed that humor that is used between colleagues is used to distance themself from tragic encounters at work. The humor that is used towards the public has the purpose to calm down stressful situations as well as gain a sort of relationship with them. These are both positive aspects of how the humor is being used by police officers, hence it gains a sense of unity within the police force and helps them cope with difficult situations. The result also showed that the moral boundaries in humor were different if you were male or female. The male officers answered that they did not have a clear line when the transgression became too big, as long as it did not become offensive toward someone else in the group. The women on the other hand all spoke about the importance of speaking up if the jokes went too far, in order to mark the line on what's okay to joke about.               Key words: Police, humor, processing, venting, cohesion, emotional management, boundary setting, moral boundaries
