  • Wind power or uranium mine : Appraisal of two energy-related environmental changes in a local context
  • 2012
  • Ingår i: Energy Policy. - Amsterdam : Elsevier. - 0301-4215 .- 1873-6777. ; 44, s. 312-319
  • Tidskriftsartikel (refereegranskat)abstract
    • This study explores factors associated with the individual’s appraisal of anticipated environmental changes caused by energy production facilities. The study took place in a Swedish village where exploratory drilling, that could eventually lead to a uranium mine, was being conducted at the same time as a wind farm was approved. Results from the survey, which included the total population, were interpreted in the light of cognitive stress theory. Most residents thought that the wind farm would have a positive impact on the village but that the uranium drilling would have a negative impact; these opinions were closely related to attitudes towards wind and nuclear power. Perceiving the wind farm as positive was further predicted by young age, high education, being an ordinary rather than a committed recycler and having attended a meeting about the wind farm. A negative view of uranium drilling was predicted by the individual valuing closeness to nature, being a recycler, and having attended the uranium meeting. Psychological factors such as concerns for the environment (manifested as pro-environmental behaviour), valuing closeness to nature, and involvement impinge on the appraisal process and should be considered when new developments are presented. © 2012 Elsevier Ltd.

  • Nanoscale Size Control of Protein Aggregates
  • 2013
  • Ingår i: Small. - : John Wiley & Sons. - 1613-6810 .- 1613-6829. ; 9:19, s. 3320-3326
  • Tidskriftsartikel (refereegranskat)abstract
    • Herein, a novel method to synthesize soluble, sub-micrometer sized protein aggregates is demonstrated by mixing native and denatured proteins without using bacteria and contaminating proteins. Ovalbumin (OVA) is employed as a model protein. The average size of the formed aggregates can be controlled by adjusting the fraction of denatured protein in the sample and it is possible to make unimodal size distributions of protein aggregates. OVA aggregates with a size of ∼95 nm are found to be more immunogenic compared to native OVA in a murine splenocyte proliferation assay. These results suggest that the novel method of engineering size specific sub-micrometer sized aggregates may constitute a potential route to increasing the efficacy of protein vaccines. The protein aggregates may also be promising for use in other applications including the surface functionalization of biomaterials and as industrial catalysis materials.

  • Factors Governing Human Fear of Brown Bear and Wolf
  • 2012
  • Ingår i: Human Dimensions of Wildlife. - London : Taylor & Francis. - 1087-1209 .- 1533-158X. ; 17:1, s. 58-74
  • Tidskriftsartikel (refereegranskat)abstract
    • This article analyzes people's subjectively experienced fear in areas with presence of brown bear or wolf. Departing from the Human-Environment Interaction Model (Küller, 1991), a hypothetical model of environmental and individual antecedents of fear was tested using structural equation modeling of survey data (n  = 391). In the model of fear of brown bear, the main predictor was the appraisal of the species as dangerous/uncontrollable and unpredictable. In the model of fear of wolf, the greater experience with the species and a stronger appraisal of wolf as dangerous, uncontrollable, and unpredictable led to low social trust and this, together with the appraisal of wolf as dangerous/uncontrollable and unpredictable, increased the likelihood of fear. Efforts to reduce human fear of wolves should focus on building trust between the public and authorities, whereas efforts to reduce fear of brown bear should focus on the individual's appraisal of the species. © 2012 Copyright Taylor and Francis Group, LLC.

  • Perceived outdoor lighting quality POLQ. A lighting assessment tool
  • 2014
  • Ingår i: Journal of Environmental Psychology. - : Elsevier BV. - 1522-9610 .- 0272-4944. ; 39, s. 14-21

    • Abstract in UndeterminedA shift towards more energy-efficient light sources for outdoor lighting such as light-emitting diodes (LEDs) is underway. Photometric measures are not sufficient to capture how users experience the light, so complementary tools are required. This study aimed to develop an observer-based environmental assessment tool, based on bipolar semantic differentials, for outdoor lighting in urban spaces. Exploratory (N = 130) and confirmatory (N = 117) factor analyses of observations of lighting installations made by laypersons on-site along pedestrian paths, resulted in two dimensions of high reliability: the Perceived Strength Quality (PSQ, Cronbach's alpha = 0.82–0.85) and the Perceived Comfort Quality (PCQ, Cronbach's alpha = 0.77–0.81). PSQ and PCQ differentiated between light sources of different illuminance level, colour temperature and colour rendering. Regression analyses showed that the perceived lighting qualities helped to explain the variance in visual accessibility, whereas PCQ helped to explain perceived danger in the environment. The perceived lighting qualities can add to the understanding of pedestrians' perception of outdoor lighting, and is proposed as a complementary tool for development of sustainable light designs in the urban environment
