Book chapter (other academic/artistic)abstract
- Motiverande samtal (MI) är en samtalsmetod som lämpar sig väl för att använda inom fysisk aktivitet, träning och idrott för att främja motivation till förändring och utveckling. MI har dock, i viss utsträckning, kritiserats för att sakna en övergripande teoribildning. Således har ett ”giftermål” mellan MI och självbestämmandeteorin (SDT) föreslagits. I detta kapitel kommer vi att redogöra för: (1) likheter och skillnader mellan MI och SDT samt hur de kan förenas; (2) grunderna i MI; (3) hur MI-samtal i såväl en fysisk aktivitets- och träningskontext som i en idrottskontext kan stärka de psykologiska behoven i SDT: autonomi, kompetens, tillhörighet (fallexempel i Bilaga 1); samt (4) redogöra för ett forskningsprojekt där integration av MI och SDT har testats i praktiken.

- In this paper, we utilize bulk acoustic waves to control the position of micropartides inside droplets in two-phase microfluidic systems and demonstrate a method to enrich the micropartides. In droplet microfluidics, different unit operations are combined and integrated on-chip to miniaturize complex biochemical assays. We present a droplet unit operation capable of controlling the position of micropartides during a trident shaped droplet split. An acoustic standing wave field is generated in the microchannel, and the acoustic forces direct the encapsulated micropartides to the center of the droplets. The method is generic, requires no labeling of the micropartides, and is operated in a noncontact fashion. It was possible to achieve 2+-fold enrichment of polystyrene beads (5 mu m in diameter) in the center daughter droplet with an average recovery of 89% of the beads. Red blood cells were also successfully manipulated inside droplets. These results show the possibility to use acoustophoresis in two-phase systems to enrich micropartides and open up the possibility for new droplet-based assays that are not performed today.

Effects of an Empowerment-Based Health-Promotion School Intervention on Physical Activity and Sedentary Time among Adolescents in a Multicultural Area
- 2018

In: International Journal of Environmental Research and Public Health. - Basel : MDPI. - 1661-7827 .- 1660-4601. ; 15:11
-
Journal article (peer-reviewed)abstract
- Physical activity (PA) decreases with age, and interventions are needed to promote PA during adolescence, especially, among those in low-socioeconomic status (SES) areas. The aim of this study was to investigate whether a two-year, empowerment-based health-promotion school intervention had any effects on changes in (a) moderate-to-vigorous PA (MVPA), (b) sedentary time (SED), (c) exercise training (ET) frequency, and (d) ET duration, among adolescents. Participants (aged 12-13 years at baseline) from one intervention school and two control schools, were recruited from a multicultural area of Sweden, characterized by low-SES. During the course of the two-year intervention, a total of 135 participants (43% boys) were included in the study. The intervention was developed and implemented as a result of cooperation and shared decision-making among the researchers and the participants. MVPA and SED were measured with accelerometers, and ET frequency and duration was self-reported at the beginning of the seventh, eighth, and ninth grade, respectively. There were no significant effects of the two-year, empowerment-based health-promotion school intervention on changes in the accelerometer-measured MVPA and SED, or the self-reported ET frequency and duration, among the adolescents. Overall, the intervention was unsuccessful at promoting PA and reducing SED. Several possible explanations for the intervention's lack of effects are discussed.

Empowering aspects for healthy food and physical activity habits : adolescents’ experiences of a school-based intervention in a disadvantaged urban community
- 2018

Journal article (peer-reviewed)abstract
- Purpose:This study aimed to describe adolescents’ experiences of participating in a health-promoting school-based intervention regarding food and physical activity, with a focus on empowering aspects. Method:The school was located in a urban disadvantaged community in Sweden, characterized by poorer self-reported health and lower life expectancy than the municipality average. Focus group interviews with adolescents (29 girls, 20 boys, 14–15 years) and their teachers (n = 4) were conducted two years after intervention. Data were categorized using qualitative content analysis. Results: A theme was generated, intersecting with all the categories: Gaining control over one’s health: deciding, trying, and practicing together, in new ways, using reflective tools. The adolescents appreciated influencing the components of the intervention and collaborating with peers in active learning activities such as practicing sports and preparing meals. They also reported acquiring new health information, that trying new activities was inspiring, and the use of pedometers and photo-food diaries helped them reflect on their health behaviours. The adolescents’ experiences were also echoed by their teachers. Conclusions: To facilitate empowerment and stimulate learning, health-promotion interventions targeting adolescents could enable active learning activities in groups, by using visualizing tools to facilitate self-reflection, and allowing adolescents to influence intervention activities.

Den undflyende lukten

Journal article (peer-reviewed)abstract
- The Fleeting Sense of Smell (Den undflyende lukten)This is an overview of the elusive sense of smell, both from a historical/cultural and psychological perspective. We follow two themes. In the first, we describe the repeated efforts to understand and categorize human olfaction, from antiquity to present day. We disseminate how smell has been positioned in sensory hierarchies, describe odor classifications systems and discuss differing views on the relationship between odor and health. The second theme regards how odors and the senseitself has been used as a means for understanding, separating and classifying other phenomena. Odors have throughout history been used to de- marcate class boundaries; the (non-)reliance of the sense of smell has been seen as an indication of civilization. Olfactory acuity is used to separate humans from animals, women from men, and young from old. These smell-based taxonomies persist, despite having no clear backing from em- pirical evidence. Finally, we suggest that the inter- est in smell may be on the rise, both from a societal and scientific perspective.
