- This paper discusses the playworlds of the Playworld of Creative Research (PWCR) research group. Play- worlds are created from a relatively new form of play that can be described as a combination of adult forms of creative imagination (art, science, etc.), which require extensive real life experience, and children’s forms of creative imagination (play), which require the embodiment of ideas and emotions in the material world. In playworlds, adults and children (or teenagers or seniors) enter into a common fantasy that is designed to support the development of both adults and children (or teenagers or seniors). The PWCR understands play- worlds and the study of playworlds as ways of being. In this paper we present unique, individual playworlds that we truly love from the perspective of researchers, artists, teachers, children, administrators, and imagi- nary characters, who participate in playworlds. We use a master fiction writer’s words on the love of literature to frame our discussion of playworlds, focusing on truth, time, human magic, infinite possibilities, fun, and the enriching and intensifying (and so, creating) of the real in playworlds in Japan, Finland, Sweden and the US.

The Comet Interceptor Mission
- 2024

Ingår i: Space Science Reviews. - : Springer Nature. - 0038-6308 .- 1572-9672. ; 220:1

Tidskriftsartikel (refereegranskat)abstract
- Here we describe the novel, multi-point Comet Interceptor mission. It is dedicated to the exploration of a little-processed long-period comet, possibly entering the inner Solar System for the first time, or to encounter an interstellar object originating at another star. The objectives of the mission are to address the following questions: What are the surface composition, shape, morphology, and structure of the target object? What is the composition of the gas and dust in the coma, its connection to the nucleus, and the nature of its interaction with the solar wind? The mission was proposed to the European Space Agency in 2018, and formally adopted by the agency in June 2022, for launch in 2029 together with the Ariel mission. Comet Interceptor will take advantage of the opportunity presented by ESA’s F-Class call for fast, flexible, low-cost missions to which it was proposed. The call required a launch to a halo orbit around the Sun-Earth L2 point. The mission can take advantage of this placement to wait for the discovery of a suitable comet reachable with its minimum Δ V capability of 600 ms − 1 . Comet Interceptor will be unique in encountering and studying, at a nominal closest approach distance of 1000 km, a comet that represents a near-pristine sample of material from the formation of the Solar System. It will also add a capability that no previous cometary mission has had, which is to deploy two sub-probes – B1, provided by the Japanese space agency, JAXA, and B2 – that will follow different trajectories through the coma. While the main probe passes at a nominal 1000 km distance, probes B1 and B2 will follow different chords through the coma at distances of 850 km and 400 km, respectively. The result will be unique, simultaneous, spatially resolved information of the 3-dimensional properties of the target comet and its interaction with the space environment. We present the mission’s science background leading to these objectives, as well as an overview of the scientific instruments, mission design, and schedule.

Konferensbidrag (refereegranskat)abstract
- Swedish preschool pedagogues have recently been coping with increased expectations to engage in “adult-led, goal oriented” teaching, and work with sustainability-related issues. In Swedish preschool provision, teaching and sustainability are contested concepts that embody pedagogical tensions (e.g. teaching as a school-like vs. a holistic activity; sustainability as an environmental and/or social concern). Some pedagogues have thus responded with ambivalence to this teaching/sustainability assignment. The present study explores how Swedish preschool pedagogues, experienced in Early Childhood Education and Care for Sustainability (ECECfS) research and practice, engage in teaching. Qualitative case studies were conducted of teacher teams from three preschools. The teams participated in a series of government-sponsored workshops for designing outdoor spaces in preschools as sustainable, multifunctional environments. Case studies were based on group interviews, surveys, and field observations. Drawing on concepts from cultural-historical activity theory, thematic analyses were conducted to characterize practitioner conceptions and practices of ECECfS and teaching in preschool. The study met all criteria for ethical conduct. Teachers described ECECfS in terms of what is learned and how. What: environmental knowledge; attitudes, feelings toward the environment, and toward others; self-confidence. How: arrangements for time “in nature”; systematic observation; pretend play; themed project work. Pedagogical tensions were identified which linked these descriptions thematically: ECECfS as teaching content vs. “teaching” values; approach vs. sensitivity to the environment; ECECfS as environmentally vs. socially focused. Implications are discussed for developing pedagogies that advance the ECECfS ethos of adult-child coparticipation in and co-determination of preschool activities.

What is Community in Early Childhood Education and Care for Sustainability? Exploring Communities of Learners in Swedish Preschool Provision
- 2022
-
Ingår i: International Journal of Early Childhood. - : Springer. - 0020-7187 .- 1878-4658. ; 54, s. 51-74

Tidskriftsartikel (refereegranskat)abstract
- In UNESCO’s recent publication Education for Sustainable Development: A Roadmap the idea of community is described as playing an important role in the organization of education for sustainable development as a means of supporting transformations towards sustainability. In the present study we examine the relationship between community and the organization of Early Childhood Education and Care for Sustainability (ECECfS). This examination is based on case studies of Swedish preschool teachers’ perspectives and practices in relation to ECECfS. Drawing on Cultural Historical Activity Theory and the concept of ontological Communities of Learners, we describe ways in which community-based characteristics of the preschools shape and are shaped by cultural tools used to pursue ECECfS. Themed-Project Work (TPW), a common means in Swedish preschools of organizing day-to-day activities, emerged as an important practice through which to examine questions of community within and across preschools. We describe organizational tensions concerning how pedagogical practices like TPW change from being tools to support a preschool’s activities, to being objects toward which these activities are oriented. Such changes can enable or constrain a preschool’s possibilities for building pluralistic and democratic ECEC environments. We also discuss how the said organizational tensions are rooted in how community is conceived of in preschool provision. Community is constituted not only through the relationships among members of individual preschools but also through the relationships that preschools have with other preschools in their administrative networks. We discuss contradictions that emerge in this matrix of relationships that shape how preschools enact good governance in the pursuit of ECECfS.

Continuous adsorption in food industry: The recovery of sinapic acid from rapeseed meal extract
- 2020
-
Ingår i: Separation and Purification Technology. - : Elsevier BV. - 1383-5866. ; 254
-
Tidskriftsartikel (refereegranskat)abstract
- Efficient recovery and utilization of valuable components from industrial food side streams is a main driver towards a circular economy. Among different available purification techniques, adsorption can effectively recover these components. However, the conventional batch mode of operation can limit its applicability in food processes due to limited efficiency. This work compares conventional batch packed bed adsorption with semi-continuous adsorption (so-called CaptureSMB) for the recovery of sinapic acid at industrial scale, using a food grade resin AmberliteTM FPX66. A mathematical mechanistic model able to describe semi-continuous operation is successfully validated and used to identify optimum operating parameters to maximize productivity and resin capacity utilization in batch and semi-continuous operating modes. The results indicate that CaptureSMB outperforms batch operation, increasing productivity from 5.18 g/L/h to 10.3 g/L/h for a given yield (>97%). A resin capacity utilization (RU) of around 70% is observed in both operating modes when productivity is maximized. A 92% RU can be accomplished for a given yield using the CaptureSMB process at a productivity of 7.0 g/L/h, higher than for conventional batch operation. The use of semi-continuous adsorption operation in food industry contributes to more efficient processes at reduced purification costs.

Baltic Sea Spray Emissions : In Situ Eddy Covariance Fluxes vs. Simulated Tank Sea Spray
- 2021
-
Ingår i: Atmosphere. - : MDPI AG. - 2073-4433. ; 12:2
-
Tidskriftsartikel (refereegranskat)abstract
- We present the first ever evaluation of sea spray aerosol eddy covariance (EC) fluxes at near coastal conditions and with limited fetch, and the first over water with brackish water (on average 7 ppt). The measurements were made on the island of Garpen in the Baltic Sea (56°23′ N, 16°06′ E) in September 2005. We found that wind speed is a major factor that is driving an exponential increase in sea spray sea salt emissions, comparable to previous studies over waters with higher salinity. We were able to show that the inclusion of a thermodenuder in the EC system allowed for the parallel measurements of the dry unheated aerosol flux (representing both organic and sea salt sea spray emissions) and the heated (300 °C) non-volatile sea salt emissions. This study’s experimental approach also included measurements of the artificial sea spray formed in a tank in locally sampled water at the same location as the EC fluxes. We attempted to use the EC aerosol flux measurements to scale the tank measurements to aerosol emissions in order to derive a complete size distribution for the sea spray emission fluxes below the size range (0.3–2 µm dry diameter) of the optical particle counters (OPCs) in the EC system, covering in total 0.01 µm to 2 µm diameter. In the wind directions with long fetches (corresponding to conditions similar to open sea), we were able to distinguish between the aerosol emission fluxes of dry aerosol and heated non-volatile (sea salt only) in the smallest size bins of the OPC, and could therefore indirectly estimate the organic sea spray fraction. In agreement with several previous ambient and tank experiments deriving the size resolved chemical mass concentration of sea salt and water-insoluble organic sea spray, our EC fluxes showed that sea sprays were dominated by sea salt at sizes ≥1 µm diameter, and by organics at the smallest OPC sizes. Since we used direct measures of the sea spray emission fluxes, we confirmed previous suggestions that this size distribution of sea salt and organics is a signature of sea spray aerosols. We were able to show that two sea salt source parameterizations (Mårtensson et al. (2003) and Salter et al. (2015)) agreed fairly well with our observed heated EC aerosol emission fluxes, as long as their predicted emissions were modified for the actual salinity by shifting the particle diameters proportionally to the cubic rote of the salinity. If, in addition, we added organics to the parameterized sea spray following the mono-layer model by Ellison et al. (1999), the combined sea spray parameterizations for sea salt and organics fell reasonably close to the observed fluxes for diameters > 0.15 µm, while one of them overpredicted the sea spray emissions below this size. The organic mono-layer model by Ellison et al. appeared to be able to explain most of the differences we observed between the aerosol emission fluxes with and without the thermodenuder.

Tidskriftsartikel (refereegranskat)abstract
- Objective: More than 50% of patients with rheumatoid arthritis (RA) are >65 years at diagnosis. Age of onset and sex may influence the disease course, outcome and treatment. This study follows a large cohort of patients with early RA to assess contributions of age and sex to disease outcomes. Methods: Patients from the BARFOT cohort, n=2837 (68% women), were followed for eight years at predefined time points to assess inflammation, function, joint destruction and treatment with disease modifying anti-rheumatic drugs (DMARDs) and glucocorticoids (GC). The patients were divided by sex and age at inclusion (<40, 40–54, 55–69 and ≥70 years). Results: For both sexes, disease activity, function and pain improved over time, significantly more in men than in women in all age groups. In men, those <40 years displayed significantly lower DAS28 compared with all other groups. This group was also the least represented group in the study. The Sharp van der Heijde Score (SHS) increased over time in both sexes and all age groups. Women ≥70 years showed less improvement in disability and the highest progression of SHS mainly due to increased joint space narrowing. Patients <40 years were more likely to receive biological DMARDs, while those ≥70 years more often received only GC treatment. Conclusion: There were significant age-and sex-dependent differences in the medical treatment and in outcome of RA 8 years after diagnosis. The differences were most pronounced in men<40 and women ≥70 years, but whether they are due to disease phenotype or treatment is unclear.
