- DN DEBATT 26/9. Vuxna bör följa uppmaningen från ungdomarna i Fridays for future-rörelsen och protestera eftersom det politiska ledarskapet är otillräckligt. Omfattande och långvariga påtryckningar från hela samhället behövs för att få de politiskt ansvariga att utöva det ledarskap som klimatkrisen kräver, skriver 171 forskare i samhällsvetenskap och humaniora.

Journal article (peer-reviewed)abstract
- Introduction. Antecedents of accompanying impairments in cerebral palsy and their relation to neuroimaging patterns need to be explored. Material and methods. A population-based study of 309 children with cerebral palsy born at term between 1983 and 1994. Prepartum, intrapartum, and postpartum variables previously studied as antecedents of cerebral palsy type and motor severity were analyzed in children with cerebral palsy and cognitive impairment and/or epilepsy, and in children with cerebral palsy without these accompanying impairments. Neuroimaging patterns and their relation to identified antecedents were analyzed. Data were retrieved from the cerebral palsy register of western Sweden, and from obstetric and neonatal records. Results. Children with cerebral palsy and accompanying impairments more often had low birthweight (kg) (odds ratio 0.5, 95% confidence interval 0.3-0.8), brain maldevelopment known at birth (p = 0.007, odds ratio infinity) and neonatal infection (odds ratio 5.4, 95% confidence interval 1.04-28.4). Moreover, neuroimaging patterns of maldevelopment (odds ratio 7.2, 95% confidence interval 2.9-17.2), cortical/subcortical lesions (odds ratio 5.3, 95% confidence interval 2.3-12.2) and basal ganglia lesions (odds ratio 7.6, 95% confidence interval 1.4-41.3) were more common, wheras white matter injury was found significantly less often (odds ratio 0.2, 95% confidence interval 0.1-0.5). In most children with maldevelopment, the intrapartum and postpartum periods were uneventful (p

- The purpose of this study was to determine whether antecedents and neuroimaging patterns vary according to the severity of motor impairment in children with cerebral palsy. Material and methods. A population-based study in which all 309 term-born children with spastic and dyskinetic cerebral palsy born between 1983 and 1994 and 618 matched controls were studied. Antecedents were retrieved from obstetric records. Information on neuroimaging was retrieved from the cerebral palsy Register of Western Sweden. Cases were grouped by severity of motor impairment: mild (walks without aids), moderate (walks with aids) or severe (dependent on wheelchair). Binary logistic regression, the Cochran-Armitage test for trends, interaction analyses and interrelationship analyses were performed. Results. Antecedents associated with mild motor impairment were antepartum (placental weight, maternal weight and antibiotic therapy) or intrapartum and postpartum adverse events (meconium-stained amniotic fluid, low Apgar score, admission to neonatal intensive care unit and neonatal encephalopathy). Antecedents associated with severe motor impairment were antepartum (congenital infection, small head circumference and brain maldevelopment) or intrapartum and postpartum (emergency cesarean section and maternal antibiotic therapy). Comparisons between mild and severe motor impairment revealed congenital infection, maldevelopment, neonatal encephalopathy and meconium aspiration syndrome significantly more often in the group with severe motor impairment (p

Från realism till post-sanning och tillbaka igen? : Nyhetsbransch, museer och högre utbildning mot fejkade nyheter och faktaresistens

Journal article (peer-reviewed)abstract
- From realism to post truth? News, museums and higher education against fake news and fact resistanceRecently, the problem with fake news, fact resistance and the growing digital, global circulation of disinformation have caused debates and worries, and posed a challenge for several institutions of knowledge in society. In this article, we discuss how the news industry, museums and higher education confront the challenges of the ‘post truth’ era. We can see a mobilization by these institutions in Sweden: The news industry has initiated so-called fact checking sites, the major museums create exhibitions about false news and educate youth in digital literacy and many universities have launched initiatives to legitimize scientific knowledge production, thereby safeguarding professional authority. However, these initiatives are faced with dilemmas concerning how concepts of knowledge, truth and facts are negotiated and understood. This article discusses such epistemological issues in general, and focuses in particular on the risk of falling into the trap of so called neorigorism.

Digital politik : sociala medier, deltagande och engagemang
- 2015
-
Editorial collection (other academic/artistic)abstract
- Den här boken handlar om hur sociala medier kan fungera politiskt i människors vardag. Digitaliseringen av samhället har starkt aktualiserat frågan om förhållandet mellan medier och deltagande. I Sverige har exempelvis de olika politiska partierna lagt mycket resurser på synlighet, inte minst via bloggar,Facebook och Twitter. Sociala nätverksmedier medför även möjligheter till en mer vardaglig form av engagemang och deltagande i en mängd olika politiska och sociala frågor.Vilken betydelse har sociala medier för exempelvis politiker, journalister och aktivister? Hur används nya digitala kommunikationstekniker för att utöva politiska påtryckningar och för politisk mobilisering? Vad innebär det att vara engagerad i dagens digitaliserade samhälle? Hur kan "det politiska" – också i termer av olika typer av livsstilar och identitetsarbete – spåras i olika gruppers och individers medieanvändning?Digital politik — Sociala medier, deltagande och engagemangbestår av tio kapitel som från olika perspektiv bidrar till att belysa och problematisera sociala mediers betydelse för "det politiska" i dag. Författarna är forskare verksamma inom humaniora och samhällsvetenskap i Sverige och Norge.

Spatial Model Predictive Control for Smooth and Accurate Steering of an Autonomous Truck
- 2017

In: IEEE Transactions on Intelligent Vehicles. - : IEEE. - 2379-8858 .- 2379-8904. ; 2:4, s. 238-250

Journal article (peer-reviewed)abstract
- In this paper, we present an algorithm for lateral control of a vehicle – a smooth and accurate model predictive controller. The fundamental difference compared to a standard MPC is that the driving smoothness is directly addressed in the cost function. The controller objective is based on the minimization of the first- and second-order spatial derivatives of the curvature. By doing so, jerky commands to the steering wheel, which could lead to permanent damage on the steering components and vehicle structure, are avoided. A good path tracking accuracy is ensured by adding constraints to avoid deviations from the reference path. Finally, the controller is experimentally tested and evaluated on a Scania construction truck. The evaluation is performed at Scania’s facilities near So ̈derta ̈lje, Sweden via two different paths: a precision track that resembles a mining scenario and a high-speed test track that resembles a highway situation. Even using a linearized kinematic vehicle to predict the vehicle motion, the performance of the proposed controller is encouraging, since the deviation from the path never exceeds 30 cm. It clearly outperforms an industrial pure-pursuit controller in terms of path accuracy and a standard MPC in terms of driving smoothness.
