  • Associations of autozygosity with a broad range of human phenotypes
  • 2019

    • In many species, the offspring of related parents suffer reduced reproductive success, a phenomenon known as inbreeding depression. In humans, the importance of this effect has remained unclear, partly because reproduction between close relatives is both rare and frequently associated with confounding social factors. Here, using genomic inbreeding coefficients (FROH) for >1.4 million individuals, we show that FROH is significantly associated (p < 0.0005) with apparently deleterious changes in 32 out of 100 traits analysed. These changes are associated with runs of homozygosity (ROH), but not with common variant homozygosity, suggesting that genetic variants associated with inbreeding depression are predominantly rare. The effect on fertility is striking: FROH equivalent to the offspring of first cousins is associated with a 55% decrease [95% CI 44–66%] in the odds of having children. Finally, the effects of FROH are confirmed within full-sibling pairs, where the variation in FROH is independent of all environmental confounding.

  • Preferences and willingness to pay for close to home nature for outdoor recreation in Sweden
  • 2015
  • In: Journal of Environmental Planning and Management. - : Informa UK Limited. - 0964-0568 .- 1360-0559. ; 58, s. 283-296
  • Journal article (peer-reviewed)abstract
    • In Sweden there is a strong tradition of using nature areas for outdoor recreation. This paper reports on a study which explored preferences and willingness to pay for outdoor recreation close to home (<= 100km away from home and <= 24hours stay at a recreation site) using the contingent valuation method. The data originated from a mail survey that involved Swedish residents who were randomly selected from a national register. An ordinary least squares regression model was used to account for factors influencing willingness to pay. The results showed that approximately 50% of the respondents used nature areas close to their home for recreation and their average frequency of visits to these areas was 74times annually. Areas dominated by forests were the most preferred, followed by water. The respondents were willing to pay approximately 7200 SEK (US$1080) annually. Their willingness to pay was influenced by factors such as type of nature area, distance to and time spent at the recreation site and income. The results provide one input to the land use planning process by considering the demand for nature-based outdoor recreation close to home.

  • Everything is possible to structure-even the software engineering body of knowledge
  • 2017
  • In: Proceedings - 2017 IEEE/ACM 1st International Workshop on Software Engineering Curricula for Millennials, SECM 2017. - : Institute of Electrical and Electronics Engineers (IEEE). - 9781538627952 ; , s. 61-67
  • Conference paper (peer-reviewed)abstract
    • Everything is possible to structure, even the software engineering body of knowledge. In this paper, we suggest a conceptual model of the software engineering body of knowledge. The model is a restructured version of SWEBOK and ACM/IEEE Curriculum Guidelines. It constitutes the first attempt to create an underlying structure that is common to most of the software engineering bodies of knowledge.

  • Viewpoints on wind and air infiltration phenomena at buildings illustrated by field and model studies
  • 2015
  • In: Building and Environment. - : Elsevier. - 0360-1323 .- 1873-684X. ; 92, s. 504-517
  • Journal article (peer-reviewed)abstract
    • Ventilation and infiltration caused by wind are difficult to predict because they are non-local phenomena: driving factors depend on the surrounding terrain and neighbouring buildings and on the building orientation with respect to the wind direction. Wind-driven flow through an opening is complex because wind can flow through the opening or around the building, in contrast to buoyancy driven flow. We explored wind and air infiltration phenomena in terms of pressure distributions on and around buildings, stagnation points, flow along façades, drag forces, and air flow through openings. Field trials were conducted at a 19th-century church, and wind tunnel tests were conducted using a 1:200 scale model of the church and other models with openings. The locations of stagnation points on the church model were determined using particle image velocimetry measurements. Multiple stagnation points occurred. The forces exerted on the church model by winds in various directions were measured using a load cell. The projected areas affected by winds in various directions were calculated using a CAD model of the church. The area-averaged pressure difference across the church was assessed. A fairly large region of influence on the ground, caused by blockage of the wind, was revealed by testing the scale model in the wind tunnel and recording the static pressure on the ground at many points. The findings of this study are summarized as a number of steps that we suggest to be taken to improve analysis and predictions of wind driven flow in buildings.
