- As with any programs in teacher education, Swedish mathematics teacher education is influenced by changing political winds, developments in Information and Communication Technology (ICT), culture, history, PISA results, research-based program designs, and a fair amount of passion. Content and outcomes are nationally determined and include the requirement of a strong research foundation, but this is often not how practcing techers work, which exerts its own pull on teacher education. The specific implementations of programs take different forms at the universities that offer mathematics teacher education. In order to provide a comprehensive yet meaningful ntroduction to both the current system and current practices, we describe the overall organization of Swedish mathematics teacher education, and then offer short cases of implemented programs. To ensure inclusivity, the various parts are written by mathematics educators from the respective institutions. In this way, both variation across mathematicas teacher education for diffrent grade levels and variation across different institutions working with the same national directives can be distinguished. Issues such as the academization of teacher education are problematized, as are other forces that constitute the crosscurrents in Swedish mathematics teacher education.

Towards WCET Analysis of Multicore Architectures using UPPAAL

- To take full advantage of the increasingly used shared-memory multicore architectures, software algorithms will need to be parallelized over multiple threads. This means that threads will have to share resources (e.g. some level of cache) and communicate and synchronize with each other. There already exist software libraries (e.g. OpenMP) used to explicitly parallelize available sequential C/C++ and Fortran code, which means that parallel code could be easily obtained. To be able to use parallel software running on multicore architectures in embedded systems with hard real-time constraints, new WCET (Worst-Case Execution Time) analysis methods and tools must be developed. This paper investigates a method based on model-checking a system of timed automata using the UPPAAL tool box. It is found that it is possible to perform WCET analysis on (not too large and complex) parallel systems using UPPAAL. We also show how to model thread synchronization using spinlock-like primitives.

Digitalisering av krisövning : Erfarenheter från CriseIT-projekten
- 2021
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Genomförandet av övningar är en nyckel till stärkt förmåga att agera effektivt i kris. CriseIT-projekten har haft som mål att bidra till detta genom att skapa möjligheter för kommuner och andra aktörer med krisövningsbehov att öva enklare och oftare.Det finns en önskan om, och en medvetenhet om behoven av, att öva mer än vad som görs i nuläget i många organisationer. Digitala verktyg är ett sätt att göra det möjligt att öva oftare, med lägre resursåtgång och kortare tid för planering och genomförande. Corona-pandemin har ytterligare gjort det tydligt vilka möjligheter digitaliseringen innebär för att effektivisera processer som tidigare varit inramade av tids-och rumsbegränsningar –t.ex. övning.Denna rapport syftar till att på ett lättillgängligt sätt redogöra för och diskutera utmaningar och möjligheter med den digitala övningsprocessen, så som den kommit till uttryck i CriseIT-projekten, genom att beskriva metodiska arbetssätt för design, genomförande och utvärdering av digitala krisövningar samt några perspektiv på implementering av digital övningsmetodik i organisationer. Målgrupp för rapporten är den som arbetar med krisberedskap i offentlig eller privat verksamhet, och som önskar lära sig mer om möjligheten att digitalisera sin övningsprocess. Arbetsrapporten är del av resultatredovisning för CriseIT2.

A Bermuda Triangle?: A Review of Method Application and Triangulation in User Experience Evaluation
- 2018

- User experience (UX) evaluation is a growing field with diverse approaches. To understand the development since previous meta-review efforts, we conducted a state-of-the-art review of UX evaluation techniques with special attention to the triangulation between methods. We systematically selected and analyzed 100 papers from recent years and while we found an increase of relevant UX studies, we also saw a remaining overlap with pure usability evaluations. Positive trends include an increasing percentage of field rather than lab studies and a tendency to combine several methods in UX studies. Triangulation was applied in more than two thirds of the studies, and the most common method combination was questionnaires and interviews. Based on our analysis, we derive common patterns for triangulation in UX evaluation efforts. A critical discussion about existing approaches should help to obtain stronger results, especially when evaluating new technologies.

Konferensbidrag (refereegranskat)abstract
- Background/Objective: The aim of this study was to assess whether home phototherapy is a safe alternative to hospital treatment.Method: This was a randomised controlled, multicentre, trial in which term newborns with a total serum bilirubin of 300-400 μmol/ were randomized to either home phototherapy or conventional in-hospital phototherapy.The outcome measurements were parent-infant bonding, stress and measurements of safety and feasibility. A descriptive qualitative study based on interviews was performed as well as a health economic analysis.Result: 147 patients were recruited from 6 hospitals, Results showed no difference between groups in the safety and feasibility outcomes. Parents in the intervention group had better scores on bonding and lower levels of stress. The interviews showed that parents felt secure at home. The cost per patient was €337 for home phototherapy compared with €1156 for the hospital alternative indicating average cost savings of €819 or 71% per patient.Conclusion: Home phototherapy can be considered a safe and feasible alternative to hospital care for well selected patients. It improves bonding and stress for parents and reduces health care costs. Since the first publication from this study was published home phototherapy is now recommended by the American Academy of Pediatrics as an alternative to hospital care for patients with uncomplicated hyperbilirubinemia.

- AIM: We aimed to evaluate whether in-home phototherapy for hyper bilirubinaemia could reduce the poorer parent-infant bonding and increased parental stress associated with neonatal hospital treatment.METHODS: In this multicentre randomised controlled trial we allocated families to either home phototherapy or standard hospital care. The primary outcome was parent-infant bonding measured on the Postpartum Bonding Questionnaire directly after therapy and 4 months later. Secondary outcomes were results on four other instruments measuring parental bonding, quality of life, and mental health.RESULTS: We randomised 78 of 147 newborn infants to intervention and 69 to the control group. No significant differences were detected in length of stay, mean bilirubin, or weight gain. Parents in the intervention group had better scores on bonding both at discharge (p = 0.034) and at 4 months (p = 0.008; effect size r = 0.2) and lower levels of stress at 4 months (p = 0.024) than controls. No statistically significant outcomes were found for the secondary outcomes.CONCLUSION: In-home phototherapy improved bonding and reduced parental stress in comparison with usual in-hospital treatment. Caregivers should consider offering home phototherapy to families of non-immunised term infants with hyperbilirubinaemia.
