- Introduction: Parkinson's disease (PD) is a neurodegenerative disease with motor and nonmotor symptoms. Coronavirus disease 2019 (COVID-19) is an infectious disease caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).Objectives: To explore how COVID-19 affects motor, nonmotor, and general health aspects of PD and to map how PD patients perceive their change in symptoms since falling ill with COVID-19.Method: The study was descriptive, case-controlled, and based on both registry and questionnaire data. At baseline, the controls were matched on age, sex, and disease severity. Information on the severity of the disease, nonmotor symptoms, motor symptoms, and general health was retrieved from the Swedish Registry for PD. Registry data from a COVID-19 group (n=45) and a control group (n=73), as well as questionnaires from a COVID-19 group (n=24) and a control group (n=42), were compared.Results: We did not find that SARS-CoV-2 infection affects any major aspect of nonmotor symptoms, motor symptoms, general health, and perception of change in PD patients' post-COVID-19. Compared to controls, the COVID-19 group reported a more positive subjective experience of pain and quality of life and a perception of change post-COVID-19 regarding general motor function, sleep quality, and mood (all p<0.05).Conclusion: Although SARS-CoV-2 infection does not seem to affect PD symptoms in any major respect, the subjective experience of several aspects of life in PD patients might be slightly improved post-COVID-19 compared to a control group. The findings warrant further investigations due to the small sample size and possible survivorship bias.

Additive Manufacturing of a Cold-Work Tool Steel using Electron Beam Melting
- 2020

Tidskriftsartikel (refereegranskat)abstract
- Metal additive manufacturing (AM) is on its way to industrialization. One of the most promising techniques within this field, electron beam melting (EBM), is nowadays used mostly for the fabrication of high‐performance Ti‐based alloy components for the aerospace and medical industry. Among the industrial applications envisioned for the future of EBM, the fabrication of high carbon steels for the tooling industry is of great interest. In this context, the process windows for dense and crack‐free specimens for a highly alloyed (Cr–Mo–V) cold‐work steel powder are presented in this article. High‐solidification rates during EBM processing lead to very fine and homogeneous microstructures. The influence of process parameters on the resulting microstructure and the chemical composition is investigated. In addition, preliminary results show very promising mechanical properties regarding the as‐built and heat‐treated microstructure of the obtained material.

Allt kan bli aktiverat och skapande liv : Öyvind Fahlströms processuella estetik
- 2023
-
Bok (övrigt vetenskapligt/konstnärligt)abstract
- Poeten och konstnären Öyvind Fahlström (1928–1976) är en av ytterst få internationellt kända svenska konstnärer under 1900-talet. När han och hans fru, bildkonstnären Barbro Östlihn, flyttade till New York 1961 kom de att bli en naturlig del av det framväxande neoavantgardet, och Fahlström erövrade omedelbart en central position i rörelsen tillsammans med framträdande konstnärer som Robert Rauschenberg, Claes Oldenburg och John Cage. Parallellt fortsatte han att skriva i svenska dagstidningar och tidskrifter och hade på så sätt ett avgörande inflytande också över det svenska kulturlivet. I den här boken utläser Per Bäckström Fahlströms estetik genom att läsa vad denne skrev i sina artiklar, manifest och program. Han lyfter i polemik med en etablerad statisk syn på konstnärskapet fram det dynamiska, processuella och performativa i Öyvind Fahlströms estetik.

Tidskriftsartikel (refereegranskat)abstract
- Performance art has been regarded as solidly rooted in the “Hierund Jetzt”, asserted by Walter Benjamin as the only remaining conditionfor the Aura. However, as Philip Auslander observes, every performancetoday is always already mediatized in one way or another,and still we might experience liveness and then also authenticity. Mediatizationis, therefore, a (necessary) condition for authenticity. Inmy discussion on the Swedish artist Öyvind Fahlström’s (1928–76) performanceKisses Sweeter than Wine 1966, I nonetheless argue that noteven the use of Verfremdungseffekts in avant-garde performance disruptsthe construction of authenticity, even though this effect is usedto attack the (presupposed) media-transparency believed to be necessaryfor an “authentic” experience. In his use of new technology anddifferent broadcasting media, Fahlström was a forerunner for mediaart. The intermedial intricacy can be fully understood and discussedonly in our own information age. His and other similar experiments inthe 1960s are important links in the genealogy of today’s networked,global and multiscreen world, since they constitute early confluencesof cybernetics, art and media. This is best seen in his performance,which was part of 9 Evenings. Theatre and Engineering arranged, in1966, by Experiments in Art and Technology (E.A.T.) at the 69th RegimentArmory in New York. Fahlström mixes performance on stagewith a plethora of mediated and mediatized events, which results ina show that is characterized by strong Verfremdungseffekts, yet stillgives rise to an experience of authenticity.

Färdplan för öppen vetenskap vid Linnéuniversitetet
- 2021
-
Rapport (populärvet., debatt m.m.)abstract
- Denna färdplan följer upp rapporten ”Implementering av öppen vetenskap vid Linnéuniversitetet: Möjligheter och problem” från december 2020, där arbetet med öppen vetenskap på Linnéuniversitetet kartlades. Bakgrunden finns både i Europeiska unionens The EU’s Open Science Policy (2019) och EU:s European Research Area Policy Agenda (2021), som har undertecknats av alla medlemsländer. Sveriges Regerings Nationell färdplan för det europeiska forskningsområdet 2019–2020, stipulerar dessutom att öppen vetenskap ska vara fullt implementerad i Sverige senast 2026, och att alla vetenskapliga texter ”ska vara omedelbart öppet tillgängliga med verkan från 2021”.Tankarna bakom öppen vetenskap ligger i linje med både Linnéuniversitetets ”Vision 2030” och ”Målsättningar 2025”, och utvecklingen av kunskapsmiljöer. Under hösten 2021 har arbetet med öppen vetenskap intensifierats inom Lnu och bland annat ägde en hearing rum den 27 oktober. Hela vägen fram till 2026 ska nu stakas ut och detta dokument ska ses som en förundersökning av och inledning på detta arbete.

Bokkapitel (refereegranskat)abstract
- In this chapter, we will focus on performance as an aesthetic orcommunicative event that unfolds at a specific time and in a specific space set apart from the social world. Not only people come together in a performance, bu talso many different kinds of materialities and media. In the unique moment ofperformance that unfolds in time and space, the performer interacts with anaudience but also with other objects: props such as the famous skull thatHamlet holds in his hand or technical devices such as the microphone in astand-up act. In this chapter, we will look closely at how different kinds ofbodies and objects interact in a performance and at how the presence and emergence of an event interact with mediation and transmediation. Pantomimes, stand-up comedy acts, drama and music concerts can be understood as different qualified media types that take place in the context of different architectural framings that already in themselves indicate which conventions areat play, what kind of performance the audience should expect and what kind ofresponse is expected from the audience.
