- In this paper, an approach to generate surrogate modelsconstructed by radial basis function networks (RBFN) with a prioribias is presented. RBFN as a weighted combination of radialbasis functions only, might become singular and no interpolationis found. The standard approach to avoid this is to add a polynomialbias, where the bias is defined by imposing orthogonalityconditions between the weights of the radial basis functionsand the polynomial basis functions. Here, in the proposed a prioriapproach, the regression coefficients of the polynomial biasare simply calculated by using the normal equation without anyneed of the extra orthogonality prerequisite. In addition to thesimplicity of this approach, the method has also proven to predictthe actual functions more accurately compared to the RBFNwith a posteriori bias. Several test functions, including Rosenbrock,Branin-Hoo, Goldstein-Price functions and two mathematicalfunctions (one large scale), are used to evaluate the performanceof the proposed method by conducting a comparisonstudy and error analysis between the RBFN with a priori and aposteriori known biases. Furthermore, the aforementioned approachesare applied to an engineering design problem, that ismodeling of the material properties of a three phase sphericalgraphite iron (SGI) . The corresponding surrogate models arepresented and compared

Tidskriftsartikel (refereegranskat)abstract
- BACKGROUND: Diabetes is a growing threat to public health, and secondary diseases like foot complications are common. Foot ulcers affect the individual's quality of life and are a great cost to society. Regular foot examinations prevent foot ulcers and are a recommended approach both in Sweden and worldwide. Despite existing guidelines, there are differences in the execution of the foot examination, which results in care inequality. A structured foot examination form based on current guidelines was developed in this study as the first step toward digitalized support in the daily routine, and was validated by diabetes health care professionals.OBJECTIVE: The study aimed to validate a structured foot examination form by assessing health care professionals' experiences of working with it "foot side" when examining patients with diabetes.METHODS: Semistructured interviews were held in a focus group and individually with 8 informants from different diabetes professions, who were interviewed regarding their experiences of working with the form in clinical practice. The users' data were analyzed inductively using qualitative content analysis. The study is part of a larger project entitled "Optimised care of persons with diabetes and foot complications," with Västra Götaland Region as the responsible health care authority, where the results will be further developed.RESULTS: Experiences of working with the form were that it simplified the foot examination by giving it an overview and a clear structure. Using the form made differences in work routines between individuals apparent. It was believed that implementing the form routinely would contribute to a more uniform execution. When patients had foot ulcers, the risk categories (established in guidelines) were perceived as contradictory. For example, there was uncertainty about the definition of chronic ulcers and callosities. The expectations were that the future digital format would simplify documentation and elucidate the foot examination, as well as contribute to the accessibility of updated and relevant data for all individuals concerned.CONCLUSIONS: The foot examination form works well as a support tool during preventive foot examination, creates a basis for decision-making, and could contribute to a uniform and safer foot examination with more care equality in agreement with current guidelines.TRIAL REGISTRATION: ClinicalTrials.gov NCT05692778; https://clinicaltrials.gov/ct2/show/NCT05692778.

- This study explores and analyzes how adult women in Sweden exposed to childhood maltreatment describe wellbeing, by using a thematic analysis of 22 semi-structured interviews with women maltreated as children. The results show that wellbeing was described as relative to both social norms and the childhood experiences and constituted four dimensions: Material and/or economic; Social and relational;Emotional; and Physical and/or mental. This study concludes that it is important to consider the relative and multiple ways wellbeing can be experienced and understood and to problematize norms of wellbeing, acknowledging the various ways people appraise their lives.

Fit for the job? How corporeal expectations shape physical education teachers' understandings of content, pedagogy, and the purposes of physical education
- 2021

Tidskriftsartikel (refereegranskat)abstract
- Background: People often expect physical education teachers to look fit and athletic, to do lots of physical activity, and to eat well. While ample research exists on physical education teachers' bodies, relatively few scholars have investigated how physical educators relate corporeal expectations to broader ideas about subject content, pedagogy, and the purposes of the school subject. Aim: The specific aim of the paper is to identify the assumptions about content, pedagogy, and educational purposes that teachers make when they talk about a perceived need for physical educators to look fit and athletic. Method: To frame our work theoretically, we draw from a Swedish didaktik of physical education tradition and employ Bakhtin's concept of speech genres, and Wertsch's concept of privileging. Our empirical material consists of transcripts generated from 6 focus group and 6 individual interviews (24 teachers in total, average age of 40 years, average teaching experience 11 years). Findings: Data suggest that when teachers use an 'athletic-looking teacher as healthy role model' speech genre, they tend to privilege: (1) a particular version of health as subject content that involves not being too overweight and maintaining physical functionality in sports. This content is based on biomedical conceptions of health which foreground exercise, eating and weight, and a pathogenic reduction of risk; (2) particular pedagogies in PE that put the teacher at the centre of the pedagogical situation, and; (3) a certain educational purpose in PE, which is to educate citizens for healthy lives through participation in sport. With respect to this purpose, increasing body weight enters the genre as a potential obstacle for educational success. Discussion: The findings raise questions concerning appropriate curricular content and its relation to teacher identities. They suggest that learning possibilities may be missed when certain content, pedagogies, and outcomes are privileged. The findings also indicate how wider voices are implicated in the speech genre. Conclusion: The paper is concluded with reflections on the possibility for change regarding expectations of physical education teachers' bodies and pedagogies.

- Aim: To provide insight into how physical education teachers use discursive resources related to obesity to create particular professional identities.Method: Data come from focus group and individual interviews with physical education teachers in Sweden. Discourse theory on teacher identities frame the analysis of the empirical material.Results: Data suggest that teachers in Sweden make use of six distinct but related discursive contributions to produce three professional identities: the caring practitioner, an identity concerned with ensuring all pupils irrespective of size participate in physical education; the activity luminary, an identity that focuses on inspiring pupils toward activity across the lifespan, and; the body rationalist, an identity concerned with challenging unrealistic media discourses and reassuring pupils that they have “normal” bodies.Discussion: The identities appear more inclusive, sensitive, and critical than current physical education literature on obesity suggests, however they also contain elements that are fundamentally unsympathetic to overweight individuals.

- Tool wear in machining changes the geometry of the cutting edges, which affects the direction and amplitudes of the cutting force components and the dynamics in the machining process. These changes in the forces and dynamics are picked up by the internal encoders and thus can be used for monitoring of changes in process conditions. This paper presents an approach for the monitoring of a multi-tooth milling process. The method is based on the direct measurement of the output from the position encoders available in the machine tool and the application of advanced signal analysis methods.The paper investigates repeatability of the developed method and discusses how to implement this in a process monitoring and control system. The results of this work show that various signal features which are correlated with tool wear can be extracted from the first few oscillating components, representing the low-frequency components, of the machine axes velocity signatures. The responses from the position encoders exhibit good repeatability, especially short term repeatability while the long-term repeatability is more unreliable.

- The concept of digital divides has been on the agenda in research and policy making for at least the last 20 years. But it is still, a challenge to grasp this concept that is so elusive and transforming. Inclusion, access and equality are still key values for democratic governance and must be addressed in particular when forming and contributing to a digital government. This paper seeks to intervene in current debates on digital divides and digital inclusion by analyzing two cases of responses among street-level public administration in relation to e-government services in Sweden. The case studies are strategically chosen and conducted in national agencies and in local public libraries. Three lines of contributions are discussed, firstly thei mportance to care for equality secondly the need to seethe non-users, and thirdly to discuss the potential of putting focus on digital diversity.

- Music and high levels of sound have not traditionally been associated with risk-taking behaviors. Loud music may intensify and bring more power and meaning to the musical experience, but it can at the same time be harmful to hearing. The present study aims to increase the knowledge about young women′s and men′s risk judgement and behaviour by investigating patterns in adolescent risk activities among 310 adolescents aged 15-20 (143 women; 167 men). The Australian instrument ARQ was used with additional questions on hearing risks and a factor analysis was conducted. The main results showed that the factor structure in the judgement and behavior scale for Swedish adolescents was rather different from the factor structure in the Australian sample. Also, the factor structure was not similar to the Australian sample split on gender. The results are discussed from a gender- and existential perspective on risk taking, and it is emphasized that research on risk behavior needs to reconceptualize stereotypical ideas about gender and the existential period in adolescence.

University teacher and student judgments on misleading behavior in study situations
- 2016
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- This study deals with teachers' and students' judgments of misleading (e.g. cheating or plagiarism) behaviors during examinations. The data was collected at a university in Sweden using a questionnaire presenting specific behaviors to bejudged. In total, 253 individuals completed the questionnaire. The teachers, incontrast to the students, tended to judge the behaviors presented as more serious. There was, however, plenty of variation in the judgments made by both teachers and students. Although the teachers, on average, tended to judge the behaviors as more serious, about 20% of the students were found to judge the behaviors as more serious than the average teacher. It was also found that about 20 % of the teachers judged the scenarios as less serious compared to the average student judgments. This indicates a lack of agreement among teachers and students on the definition of misleading behavior. Subjective opinions seem to play a more important role for judgment than having actual knowledge about the rules and regulations stating what misleading behaviors really are inacademic work.
