Konferensbidrag (refereegranskat)abstract
- This study explores the opportunities and challenges of teaching under flexible spatial and digital conditions of the learning environment of a newly build school, analyzing how teaching is organized and what curricular genres can be discerned, what resources and practices are offered to stimulate students meaningmaking and what framing, relations and accessibility can be distinguished by the flexibility of furniture and classroom space. The analyses of a teacher team’s planning and teaching of the thematic work project on Space in years 2-3 (ages 8 to 9) and another teacher team’s thematic work project onCommunication in years 4-7 (ages10 to12) reveal varied teaching strategies between teacher-led and student-centered forms offering students linguistic, visual and audiovisual resources to make meaning of shared content in different school subjects. The young students practice reading comprehension, both of written texts and films, that also serves their knowledge-building about space. The older students display skills relating to different subjects through different technological and digital resources.

Tema, rum och digitalisering i ny skolverksamhet : Slutrapport från projektet Digiflex Didaktisk Design i Samverkan
- 2023
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Sveriges befolkning ökar och med det följer om- och nybyggnation av skolor med förväntningar på innovativa skolmiljöer som erbjuder god arbetsmiljö för elever och lärare och främjar en modern, elevcentrerad och elevaktiv pedagogik. Detta projekt var baserat i en sådan nybyggd skola som erbjuder flexibilitet i variation av rum och öppna ytor, flyttbara möbler och digital teknologi i sin utformning.Syftet med projektet har varit att utveckla förståelse för den nybyggda skolans lärmiljö och studera hur skolans flexibla rumsliga och digitala ramar påverkar lärares undervisning och elevers kunskapsutveckling med utgångspunkt i följande frågeställningar:1. Hur används skolans fysiska och digitala rum i lärares undervisningsdesign?2. Hur kan elevers kunskapsutveckling stöttas genom rumslig och digital undervisningsdesign?3. Hur utnyttjas fysiska och digitala rum för att lyckas med det kompensatoriska uppdraget?Projektets har tillämpat co-design metoder, en kombination av aktionsforskning och design-baserad forskning, där lärare och forskare systematiskt och tillsammans studerat förändring och utveckling av undervisning i skolans lärmiljö över tid. Projektet har fokuserat på lärares didaktiska planering, undervisning och reflektion, möblering och rörelse i och mellan rummen, användning av digitala resurser, anpassning till elever samt ledarskapets roll. I utvecklingen av undervisningsdesign ingick kollegial planering, uppföljning, reflektion och re-design av undervisning i workshopsformat utifrån en tidigare utvecklad meta-tänkande modell för didaktisk design kallad Tanketärningar. Undervisningsdesignen har prövats i småskaliga interventioner och studerats genom observationer av lärares och elevers praktiker. En återkommande enkät har använts för att fånga lärarnas individuella röster. Dessutom genomfördes samtal och intervjuer med lärare och ledare på skolan.Resultaten visar på att skolans flexibla rumsliga och digitala lärmiljö ställer nya krav på lärare att tänka organisatoriskt runt elevflöden och digitala resurser i undervisningen. Lärares varierande rumsliga inramningar av undervisningen mellan fri rörlighet och statiska arrangemang ger möjligheter till olika relationsbyggande. Skolans goda digitala infrastruktur erbjuder lärarna ett multimodalt planeringsstöd och flexibilitet i feedback och anpassning av innehåll till eleverna. Dock kan den digitala undervisningen även framkalla hårt paketerad och ”klicka-sig-fram” undervisning som minskar lärares handlingsutrymme och elevinflytande. Lärare skolar in elever till en strukturerad flexibilitet för att hantera rumslig och digital variation som uppfattas även ge utrymme att möta eleverna individuellt när andra elever i gruppen arbetar mer självständigt. Samtidigt är inte lärmiljön anpassad för elever som kräver en högre grad av didaktiskt ledarskap.Samverkansambitioner har utmanats under projektets gång av coronapandemin men också oregelbundenheten i möten utöver workshoppar. Personalomsättning har påverkat relationsbygget mellan lärare och forskare över tid. Verksamhetens kollegiala arbete i lärarlag och ämnesövergripande undervisning utifrån ett fokus på tematiskt arbete har visat sig utmana lärarrollen, främst i de högre årskurserna. Projektets resultat pekar tydligt på vikten av kollegial samsyn och ledarskapets roll i det pedagogiska arbetet. Flexibiliteten behöver tolkas och kräver omfattande kollektiv planering i lärarlag som behöver ges tid och handlingsutrymme.Projektets resultat har spridits kontinuerligt genom skolans webbsida, vetenskapliga publikationer, presentationer och workshoppar på forskningskonferenser, föredrag i Göteborgs stad som listas i slutet på rapporten. En film har samproducerats om arbetet med tanketärningsmodellen. Under projektets gång producerades sex examensarbeten på lärarutbildningarna och en masteruppsats inom informatik. Masteruppsatsen skrevs om till ett vetenskapligt prisbelönt bidrag.

Tidskriftsartikel (refereegranskat)abstract
- INTRODUCTION: Research indicates that newly graduated registered nurses struggle to develop practical skills and clinical understanding and to adapt to their professional role. To ensure quality of care and support new nurses, it is vital that this learning is elucidated and evaluated. Aim The aim was to develop and evaluate the psychometric properties of an instrument assessing work-integrated learning for newly graduated registered nurses, the Experienced Work-Integrated Learning (E-WIL) instrument.METHOD: The study utilized the methodology of a survey and a cross-sectional research design. The sample consisted of newly graduated registered nurses (n = 221) working at hospitals in western Sweden. The E-WIL instrument was validated using confirmatory factor analysis (CFA).RESULTS: The majority of the study participants were female, the average age was 28 years, and participants had an average of five months' experience in the profession. The results confirmed the construct validity of the global latent variable E-WIL, "Transforming previous notions and new contextual knowledge into practical meaning," including six dimensions representing work-integrated learning. The factor loadings between the final 29 indicators and the six factors ranged from 0.30 to 0.89, and between the latent factor and the six factors from 0.64 to 0.79. The indices of fit indicated satisfactory goodness-of-fit and good reliability in five dimensions with values ranging from α = 0.70 to 0.81, except for one dimension showing a slightly lower reliability, α = 0.63, due to the low item number. Confirmatory factor analysis also confirmed two second-order latent variables, "Personal mastering of professional roles" with 18 indicators, and "Adapting to organisational requirements" with 11 indicators. Both showed satisfactory goodness-of-fit, and factor loading between indicators and the latent variables ranged from 0.44 to 0.90 and from 0.37 to 0.81, respectively.CONCLUSION: The validity of the E-WIL instrument was confirmed. All three latent variables could be measured in their entirety, and all dimensions could be used separately for the assessment of work-integrated learning. The E-WIL instrument could be useful for healthcare organisations when the goal is to assess aspects of newly graduated registered nurses' learning and professional development.

Tidskriftsartikel (refereegranskat)abstract
- Aim: The aim of this study was to describe newly graduated nurses´(NGNs´) experience of work-integrated learning (WIL), from an educational and occupational perspective.Background: NGNs often find themselves unprepared to meet occupational demands on their competence on entering working life, and express difficulties integrating educational theory into a practical context. Qualitative and effective WIL becomes particularly important for NGNs to develop the competence required to handle the transition from education to working life.Design: This is a qualitative, descriptive study with an inductive approach.Methods: Seven focus-group discussions were performed and subjected to qualitative content analysis.Results: The results revealed that WIL for NGNs includes personal mastering of several professional roles: a self-directed and collaborative learning role, a relational nursing role, and a transition from a student role to a collegial role. Furthermore, WIL entails adapting to organisational requirements, including development of contextual workplace knowledge and understanding; striving for confidence in medical-technical performance; and developing an experience-based understanding of clinical situations.Conclusion: The results reveal that WIL is complex, encompassing adaptation to roles and personal capabilities that increase new graduates´competence and preparation for work. In addition, WIL requires personal commitment to one’s own learning as well as organisational and social support.

Tidskriftsartikel (refereegranskat)abstract
- Background: Relatives of a person suffering from cancer risk being affected both physically and psychologically. Blogging has become increasingly popular as a forum for communicating experiences, but few studies have focused on what blogging about a relative's cancer journey means to the author. Aim: To illuminate relatives' experiences of blogging when a family member is in the end-of-life phase of cancer. Method: Telephone interviews were conducted with 12 people about their experiences of blogging during and after their family member's illness. The data was analysed using qualitative content analysis. Findings: Blogging facilitated everyday life, introduced the relatives to new friends with similar experiences, helped them in their grief process, and helped them to preserve memories. The negative aspects were being misunderstood and publicly criticised as well as the feeling of providing readers with 'reality show' entertainment. Conclusion: Blogging was seen as a complement to professional care that contributed to the prevention of ill health.

Tidskriftsartikel (refereegranskat)abstract
- There is a lack of knowledge about the early phase of severe infection. This report describes the early chain of care in bacteraemia as follows: (a) compare patients who were and were not transported by the Emergency Medical Services (EMS); (b) describe various aspects of the EMS chain; and (c) describe factors of importance for the delay to the start of intravenous antibiotics. It was hypothesized that, for patients with suspected sepsis judged by the EMS clinician, the delay until the onset of antibiotic treatment would be shorter.All patients in the Municipality of Gothenburg (Sweden) with a positive blood culture, when assessed at the Laboratory of Bacteriology in the Municipality of Gothenburg, from February 1 through April 30, 2012 took part in the survey.In all, 696 patients fulfilled the inclusion criteria. Their mean age was 76 years and 52% were men. Of all patients, 308 (44%) had been in contact with the EMS and/or the emergency department (ED). Of these 308 patients, 232 (75%) were transported by the EMS and 188 (61%) had “true pathogens” in blood cultures. Patients who were transported by the EMS were older, included more men, and suffered from more severe symptoms and signs.The EMS nurse suspected sepsis in only six percent of the cases. These patients had a delay from arrival at hospital until the start of antibiotics of one hour and 19 minutes versus three hours and 21 minutes among the remaining patients (P =.0006). The corresponding figures for cases with “true pathogens” were one hour and 19 minutes versus three hours and 15 minutes (P =.009).Among patients with bacteraemia, 75% used the EMS, and these patients were older, included more men, and suffered from more severe symptoms and signs. The EMS nurse suspected sepsis in six percent of cases. Regardless of whether or not patients with true pathogens were isolated, a suspicion of sepsis by the EMS clinician at the scene was associated with a shorter delay to the start of antibiotic treatment.

- 2024
-
Ingår i: Applied Sciences. - 2076-3417. ; 14:17, s. 7572-7572

Tidskriftsartikel (refereegranskat)abstract
- The PH 13-8 Mo family of steels belong to the martensitic precipitation hardening stainless steels (MPHSSs) category, which exhibits a good combination of mechanical properties and corrosion resistance. Additive manufacturing (AM) offers advantages, including reduced material waste and the capability to produce complex, near-net-shape parts. Consequently, the application of AM techniques to the PH 13-8 Mo family is being increasingly explored across various industries. This review paper presents the existing literature on the topic and provides an overview. The review starts by presenting information about the PH 13-8 Mo family, including microstructure, chemical compositions, heat treatments, and mechanical properties. Afterwards, the work focuses on presenting the microstructure and resulting properties of PH 13-8 Mo family processed by three different additive manufacturing processes: Powder Bed Fusion using a Laser Beam (PBF-LB), Directed Energy Deposition using an Electric Arc (DED-Arc), and Directed Energy Deposition using a Laser Beam (DED-LB), both in their as-built condition and following post-processing heat treatments. The review concludes with a summary and outlook that highlights existing knowledge gaps and underscores the need for further research to tailor the microstructural evolution and enhance the properties. The findings indicate that AM of the PH 13-8 Mo family has the potential for industrial applications, yet further studies are necessary to optimize its performance.

Tidskriftsartikel (refereegranskat)abstract
- The combination of corrosion resistance and mechanical properties of martensitic precipitation hardening stainless steels (MPHSS) makes them well suited for demanding applications in aerospace, high-pressure gas bottles, or in injection molding of corrosive plastics. Directed energy deposition methods and specifically the laser metal deposition process with powder as feedstock (LMDp) have the potential to be applied in the production of such components. It is well-known that the geometrical features of the deposited beads such as aspect ratio and dilution are crucial for process efficiency and deposition quality. Therefore, this work aims at understanding the influence of the process parameters and the resulting microstructure of a MPHSS modified PH 13-8Mo alloy when using LMDp. Design of experiment (DoE) was used to plan and analyze the influence and interaction of the different LMDp process variables in the geometry of the deposits. It was found that height, width, and depth were statistically significantly influenced by speed, while height was also considerably influenced by the powder feeding rate. In terms of laser power, it was the most significant factor for the width and the depth, but it did not significantly affect the height of the beads. The results showed that the as-deposited microstructure of the modified PH 13-8Mo under the LMDp conditions investigated in this work consists of a martensitic matrix with some amount of primary δ ferrite. The presence of a low amount of retained austenite and aluminum-enriched inclusions was confirmed. This work enhances the fundamental process and material understanding of LMDp of the modified PH 13-8Mo alloy as a first stage in the fabrication of additively manufactured components.

Tidskriftsartikel (refereegranskat)abstract
- Modified PH 13-8Mo alloy exhibits a good combination of corrosion resistance and mechanical properties for demanding applications in aerospace, petrochemical, and tooling industries. Additive manufacturing, specifically the laser metal deposition process with powder as feedstock (LMDp), has the potential to be utilized in these industries. However, very limited knowledge on the LMDp of this alloy currently exists. The aim of this work was, therefore, to deposit a multi-track single layer of modified PH 13-8Mo alloy as a first step towards 3D geometries, and to analyze the resulting microstructure by using Optical Microscopy, Scanning Electron Microscopy, X-Ray Diffraction, Electron Backscatter Diffraction, and micro-hardness. It was found that the multitrack single layer was free from major defects. The microstructure was heterogeneous, and it consisted of a martensitic matrix and small amounts of δ ferrite, austenite, and AlN. The results of this research will be used to tailor the microstructure and properties of future 3D additively manufactured components.

Corrosion resistance and microstructure analysis of additively manufactured 22% chromium duplex stainless steel by laser metal deposition with wire
- 2023

Ingår i: Journal of Materials Research and Technology. - 2238-7854 .- 2214-0697. ; 26, s. 6741-6756

Tidskriftsartikel (refereegranskat)abstract
- Microstructure characteristics and pitting corrosion of a duplex stainless steel (DSS) manufactured by laser metal deposition with wire (LMDw) were studied. The layer-by-layer LMDw process resulted in a mixed microstructure of predominantly ferrite with 2% austenite and chromium-rich nitrides, and reheated regions with ~33% austenite. The high cooling rate of LMDw restricted the distribution of Cr, Mo, and Ni, in ferrite and austenite, while N diffuses from ferrite to austenite. Subsequent heat treatment at 1100 C for 1 h resulted in homogenized microstructure, dissolution of nitrides, and balanced ferrite/austenite ratio. It also led to the redistribution of Cr and Mo to ferrite, and Ni and N to austenite. At room temperature, cyclic potentiodynamic polarization measurements in 1.0 M NaCl solution showed no significant differences in corrosion resistance between the as-deposited and heat-treated samples, despite the differences in terms of ferrite to austenite ratio and elemental distribution. Critical pitting temperature (CPT) was the lowest (60 C) for the predominantly ferritic microstructure with finely dispersed chromium-rich nitrides; while reheated area with ~33% austenite in as-deposited condition achieved higher critical temperature comparable to what was obtained after heat treatment (73 and 68 C, respectively). At temperatures above the CPT, selective dissolution of the ferrite after deposition was observed due to depletion of N, while after heat treatment, austenite preferentially dissolved due to Cr and Mo concentrating in ferrite. In summary, results demonstrate how microstructural differences in terms of ferrite-to-austenite ratio, distribution of corrosion-resistant elements, and presence of nitrides affect corrosion resistance of LMDw DSS.
