- In response to global challenges in resource supply, many industries are adopting the principles of the Circular Economy (CE) to improve their resource acquisition strategies. This paper introduces an innovative approach to address the environmental impact of waste Glass Fiber Reinforced-Polymer (GFRP) pipes and panels by repurposing them to manufacture structural components for new bicycle and pedestrian bridges. The study covers the entire process, including conceptualization, analysis, design, and testing of a deck system, with a focus on the manufacturing process for a 7-m-long prototype bridge. The study shows promising results in the concept of a sandwich structure utilizing discarded GFRP pipes and panels, which has the flexibility to account for variabilities in dimensions of incoming products while still meeting mechanical requirements. The LCA analysis shows that the transportation of materials is the governing contributing factor. It was concluded that further development of this concept should be accompanied by a business model that considers the importance of the contributions from the whole value chain.

- The article discusses the importance of personal sporting skills in PE Teacher Education. The article is based on interviews with a group of teachers in PE Education. They were interviewed about how they perceive the needs of skills in PE Students. The article also discusses the diminished importance in PE Education of the need of physical literacy. A particular focus is on the discussion of personal skills in dancing and in ball games. The results show that there is a difference between how the PE educators talk about personal skills in dance and in ball games. There is consensus concerning the importance of the need for good personal ability in dancing, which also permeates the exams that the students are doing. In ball games, on the other hand, the discussion underlines the importance of general skills in coaching and leadership rather than personal skills in various ball games, in order to create good learning situations for different groups of pupils.

EQUALITY IN PHYSICAL EDUCATION IN SWEDEN DURING TWO DECADES
- 2022
-
Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- Introduction: Education equality is a central goal in well-fair states around the world. In Sweden, the school and the subject physical education (PE) should be equal and compensate for students’ different backgrounds, e.g. socioeconomic, - and migration background. Although equality is a central goal, little is known about how equality in PE has changed during the last decades (Jansson et al., 2021). One approach to study equality is to analyze how grades for biological siblings correlate – this captures all aspects that siblings share, among others, socioeconomic, - and migration background. Although this approach is well established in educational research, there are no studies in PE-research (Jansson et al., 2021). As a result, there is limited knowledge about the extent to which students’ backgrounds have affected their grades in PE. Therefore, the aim of this study is to analyze how equality in PE in Sweden has changed over the last two decades. Method: The method is based on quantitative analyzes of students’ (N = 5,848,642) grades in PE, between the years 1999-2019. The method is based on analyzing correlations between siblings’ grades, using variance decomposition. More precisely, analyzing the correlation between full siblings, born within a three-year window, and their annually standardized grades in PE. In addition to socioeconomic, - and migration background, the measure takes into account all the aspects that full siblings share, such as: upbringing, genetic factors, living conditions, parenting and regional factors. Results: In relation to the total variation in students’ grades in PE, the proportion explained by variation between siblings has increased between the years 1999-2019. That is, the results indicate that the importance of students’ family background, over the past two decades, has become more important for students’ grades in PE. Furthermore, the largest increase in sibling correlation is found within the group of students born abroad.Discussion: The results indicate that equality in PE in Sweden has deteriorated. This can be explained by that, between 1999 and 2019, (i) the student group has become more heterogeneous, i.e., it has become more difficult to compensate for students’ different backgrounds; (ii) PE has become worse at compensating for students with different backgrounds, e.g. lower socioeconomic background.Reference: Jansson, A., Sundblad, G.

- Research about physical education teacher education (PETE) indicates that the education program attracts homogeneous groups of students, consisting mainly of young men originating from the country in question and who have academic backgrounds. The purpose of this article is, through a case study of one Swedish PETE institution, to explore a cohort of 60 students regarding background characteristics (gender, social and migration background) and secondary characteristics (school success, experience of sport and physical activity cultures, and perceived physical ability). The case study indicated that the students have slightly more diverse backgrounds than is found in previous PETE research, but at the same time, they remain fairly homogeneous regarding, e.g. such as school success, the experience of sport and physical activity, and perceived physical ability. Attracting a more diverse group of students does not mean necessarily that the students are equally diverse when it comes to experiences of movement culture, and the abilities and knowledge that they have gained from participation in this culture.

- Introduction: Research has indicated that Physical Education (PE) is often characterized by teacher-centred teaching (e.g. Byra 2006; Tinning 2010), where the pupils follow instruction and perform pre-established movements (Karlefors and Larsson 2018). Pupils are expected to listen, do as they are told, and follow rules (Fitzpatrick and Russell 2015; Quennerstedt 2013). PE teaching has been described as an act of control (Quennerstedt 2013), and teachers face the dilemma of letting go of control and still having enough control to make sure that the lesson smoothly moves forward (Alfrey and O'Connor 2020). However, when the pupils are given more power and the teacher applies student-centred teaching, the pupils get to come up with ideas and make decisions (e.g. Byra 2006; Garrett and Wrench 2018; Mattsson and Larsson 2021). This is significant because it can develop PE and contribute to meaning making among pupils and their experiences of movement. This article aims to analyse the use of exploratory circus assignments in PE teaching and to discuss this in relation to current school norms. Biesta's (The Beautiful Risk of Education [Paradigm Publishers 2014]) concept of risk, which means not knowing the outcome, is used. The article problematizes pupils' own ideas and suggestions in relation to prevailing norms in school. What happens when pupils participate in teaching based on exploratory circus assignments? Exploration, playfulness, and expression were focused, and the lessons were characterized by the absence of primary focus on competitiveness as a counterweight to traditional PE content. Methods: A research teacher (a university teacher with experience teaching school PE and circus) conducted 10 lessons together with 20 pupils (aged 10) and their PE teacher using exploratory circus assignments. Data was collected through participant observation, video observation, and field diary. The data analysis generated three themes, Following instruction, Limited exploration, and Shared power, that were reviewed in relation to the theoretical framework. Results: The results show that the research teacher and the PE teacher resisted embracing risk in PE due to the prevailing norms and what Biesta (2014) describes as the practice of schooling. They focused on keeping the pupils in order rather than being flexible and open to unknown outcomes. The exploratory circus assignments involved risk to different extents, and the research teacher's tendency to embrace risk increased over time. Her letting go of control enabled her to embrace risk. It did not mean a total relinquishment of control, but rather not having exclusive control over the decision-making and meaning-making processes. When she shared the power with the pupils, new and other movements could be explored. The results show that pupils' actions can be more educative than what teachers initially consider. Conclusion: Teachers need to relinquish control to conduct teaching which embraces risk. Doing so enables them to share power with the pupils, which allows pupils to explore and discover different ways of moving and using the material. Exploratory circus assignments can enable risk embracement in PE and function as a way for teachers to reflect upon pedagogical considerations and practice the sharing of power with their pupils.

- Air infiltration has great importance regarding energy, comfort, moisture and dust deposition in naturally ventilated historical buildings like churches. In these buildings, air infiltration is driven by stack effect and wind. When assessing the wind effect, reasonable estimation of wind pressure coefficients is crucial. Local wind pressure coefficients are significantly affected by the shape of the building and turbulence generated by its geometrical features, which – for moderately large churches – typically consist of main building body and window recesses, gable roof, tower, apse, and sacristy. To yield practically useful pressure coefficients, this study conducted wind tunnel and numerical investigations at a church, with gradual addition of these features. Wind pressure was measured on a small-scale model in a wind tunnel, while computational fluid dynamics (CFD) simulations were carried out for both small-scale and full-scale models. By comparing the experimental and numerical results, the SST k–ω turbulence model showed the best accuracy, yielding CFD results in good agreement with wind tunnel measurements. Most challenging was predicting the strong negative wind pressures occurring on a flat roof. Building structures like tower, apse, and sacristy had significant impact on the wind pressures on the central, main building body. This study adds knowledge on wind pressure effects by commonly occurring building components, with particular reference to churches and similar buildings. It was an important basis for developing further models for calculating the wind pressure coefficient.
