- Cooperative awareness basic services are key components of several Connected Autonomous Vehicles (CAV) functions. We present a rigorous approach to the analysis of cooperative awareness basic services in a CAV setup. Our approach addresses a major challenge in the traditional analysis techniques of such services, namely, coming up with effective scenarios that can meaningfully cover their various behaviours, exercise the limits of these services and come up with a quantitative means for design-space exploration.Our approach integrates model-based testing and search-based testing to automatically generate scenarios and steer the scenario generation process towards generating inputs that can lead to the most severe hazards. Additionally we define other objectives that maximise the coverage of the model and the diversity of the generated test inputs. The result of applying our technique to the analysis of cooperative awareness services leads to automatically generated hazardous scenarios for parameters that abide by the ETSI ITS-G5 vehicular communications standard. We show that our technique can be used as an effective design-space exploration method and can be used to design adaptive protocols that can mitigate the hazards detected through our initial analysis. © 2020 by IEEE

- © Author(s) 2019. Aims: The aim of this study was to investigate the prevalence of cybervictimization in the six Nordic countries and to assess its overlap with traditional bullying. A further aim was to examine potential associations between life satisfaction, on the one hand, and traditional bullying and cyberbullying on the other. Methods: Analyses were based on data from the 2013⁄2014 Health Behaviour in School-aged Children study. It included 32,210 boys and girls, aged 11, 13, and 15, living in the six Nordic countries. Results: The prevalence of cyberbullying by both pictures and by messages was around 2% in all the Nordic countries except Greenland. There it was considerably higher. The prevalence of being bullied in a traditional manner varied widely by country. For boys, this type of bullying was most frequent in the youngest age group and then decreased steadily in the older age groups. Girls were on average more likely to be cyberbullied. Cyberbullying was more common among 13- and 15-year-olds than 11-year-olds. Higher family affluence was unrelated to the risk of cyberbullying. However, it was related to traditional bullying and combined forms of bullying. Compared with intact families, cybervictimization was commoner among single-parent families and stepfamilies. Adjusting for age, gender, family affluence, and family structure, those subjected to cyberbullying had lower life satisfaction than those who were not bullied. Conclusions: We found relatively little overlap between cyberbullying and traditional bullying, indicating that the two may be separate phenomena stemming from different mechanisms, at least in the Nordic context.

- Studien analyserar sambanden mellan sysselsättning för unga vuxna med intellektuell funktionsnedsättning som gått i gymnasiesärskolan och deras sociala bakgrund, mätt som föräldrarnas utbildningsnivå och geografiska härkomst. Den här registerstudien baseras på Halmstad university register on pupils with intellectual disabilities (HURPID), Longitudinell integrationsdatabas för arbetsmarknads- och sjukförsäkringsstudier (LISA) samt LSS-registret. Studien omfattar 12 269 unga med intellektuell funktionsnedsättning som gick ut gymnasiesärskolan mellan 2001 och 2011. De samband som studeras analyseras genom multipla logistiska regressioner. Resultaten visar att föräldrars utbildningsnivå har viss betydelse för före detta gymnasiesärskoleelevers sysselsättning. Barn till högutbildade föräldrar har med större sannolikhet en sysselsättning inom daglig verksamhet och barn till lågutbildade föräldrar har med större sannolikhet ett förvärvsarbete. Sannolikheten för att ha någon av sysselsättningskategorierna daglig verksamhet eller förvärvsarbete är lägst bland barn till föräldrar som är födda i länder utanför Norden. Högutbildade föräldrar antas ha en högre grad av den ”välfärdskompetens” som krävs för att hantera dagens välfärdssystem och härigenom kunna påverka de ungas möjligheter att få insatser likt daglig verksamhet. Lågutbildade föräldrar antas ha egna erfarenheter av, och kontakter med, arbetsplatser där det finns arbetsuppgifter utan (eller med låga) formella kompetenskrav. Samhällets kunskaper och medvetenhet om den sociala bakgrundens betydelse för efter(sär)gymnasial sysselsättning bland unga med intellektuell funktionsnedsättning behöver öka. Detta i syfte att bättre möta varierande individuella förutsättningar och främja etablering i arbetslivet för fler unga vuxna med intellektuell funktionsnedsättning vid övergången från skoltid till arbetsliv.

- Accurate and comprehensive healthcare data coupled with modern analytical tools can play a vital role in enabling care providers to make better-informed decisions, leading to effective and cost-efficient care delivery. This paper describes a novel strategic healthcare analysis and research platform that encapsulates 360-degree pseudo-anonymized data covering clinical, operational capacity and financial data on over 500,000 patients treated since 2009 across all care delivery units in the county of Halland, Sweden. The over-arching goal is to develop a comprehensive healthcare data infrastructure that captures complete care processes at individual, organizational and population levels. These longitudinal linked healthcare data are a valuable tool for research in a broad range of areas including health economy and process development using real world evidence.Key messagesStructured and standardized variables have been linked from different regional healthcare sources into a research information platform including all healthcare visits in the county of Halland in Sweden, from 2009 to date.Since 2015, the regional information platform integrates a cost component to each healthcare visit: thus being able to quantify patient level value, safety and cost efficiency across the continuum of care. © The Author(s) 2020; all rights reserved.

- BACKGROUND: Non-alcoholic fatty liver disease (NAFLD) is highly prevalent and causes serious health complications in individuals with and without type 2 diabetes (T2D). Early diagnosis of NAFLD is important, as this can help prevent irreversible damage to the liver and, ultimately, hepatocellular carcinomas. We sought to expand etiological understanding and develop a diagnostic tool for NAFLD using machine learning. METHODS AND FINDINGS: We utilized the baseline data from IMI DIRECT, a multicenter prospective cohort study of 3,029 European-ancestry adults recently diagnosed with T2D (n = 795) or at high risk of developing the disease (n = 2,234). Multi-omics (genetic, transcriptomic, proteomic, and metabolomic) and clinical (liver enzymes and other serological biomarkers, anthropometry, measures of beta-cell function, insulin sensitivity, and lifestyle) data comprised the key input variables. The models were trained on MRI-image-derived liver fat content (

Att styra på tvären. Tre studer om tvärsektoriell koordinering och dess aktörer i offentlig förvaltning
- 2020
-
Samlingsverk (redaktörskap) (övrigt vetenskapligt/konstnärligt)abstract
- Idag uppfattas alltfler frågor som komplexa och som i behov av strategisk samordning och tvärsektoriell koordinering. Detta har gett till upphov till nya roller och professioner i den offentliga förvaltningen. Dessa kallas ofta strateger och samordnare och återfinns på alla nivåer i den offentliga sektorn. Forskningen om dessa roller är mycket begränsad, dock finns ett stort behov av fördjupning av de utmaningar som aktörerna möter. I denna rapport presenteras tre fördjupande studier på detta tema. Anton Holmgren Jonsson undersöker hur kommunala politiker förhåller sig till sina jämställdhetsstrateger och huruvida strategerna fungerar som styrinstrument för den beslutade politiska inriktningen. Johanna Jansson utforskar hur folkhälsostrateger hanterar och formar sin professionella roll då förväntningarna på vad de ska göra inte alltid är tydliga och konsekventa. Josephine Massie studerar hur nationella samordnare fungerar som styrinstrument mellan olika administrativa nivåer. Dessa studier är skrivna som examensarbeten inom masterprogrammet i offentlig förvaltning under år 2016. Författarna är alla pol. master vid Förvaltningshögskolan, Göteborgs universitet och har idag (januari 2020) olika roller inom statlig, regional och kommunal offentlig förvaltning. Rapportens redaktör, Petra Svensson, är fil. dr i offentlig förvaltning med inriktning mot tvärsektoriell styrning och organisering och handledde arbetet med de tre studierna. ©2020 Författarna

Forskningsöversikt (refereegranskat)abstract
- In the last two decades, questions have been raised against the relevance of business education all around the globe including the famous MBA program. Despite few shortcomings of western MBA programs, they are considered to be the global benchmark owing to their reputation, quality, research focus etc., whereas most of their Chinese counterparts are criticized heavily for their different weaknesses ranging from obsolescence and incorporating unique Chinese characteristics to blindly following the US model, without devising the right mix. This study compares the Chinese MBA with the Western MBA programs, highlighting the crucial weaknesses prevailing in Chinese MBA programs and then identifying the necessary improvements to bring them at par with their western counterparts. The study also contributes by bringing-forth 'must have' and 'can have' courses as a part of the MBA curriculum by going through both Western and Chinese MBA curriculums in depth. © 2020 Copyright 2020 by Koninklijke Brill NV, Leiden, The Netherlands.

Tidskriftsartikel (refereegranskat)abstract
- The main impetus for lower distribution temperatures in district heating systems is the lower heat supply costs obtained by these lower temperatures. In this paper, the differences in heat supply costs for two different temperature levels have been estimated for various future heat supply options. The estimations were obtained by modelling a district heating system characterised by typical climate conditions for Central Europe. High sensitivity to lower supply costs from lower temperatures was found for geothermal heat, industrial excess heat, and heat pumps, whereas low cost sensitivity was estimated for combined heat and power plants using waste or biomass. Lower heat distribution loss constitutes a minor component of the total cost reductions. The current use of high heat distribution temperatures was identified as an important barrier for the transition to renewable and recycled heat supply in district heating systems. Hence, lower distribution temperatures would facilitate this required transition because lower distribution temperatures provide higher profitability for these renewable and recycled heat sources. © 2019 The Authors.

Low‐temperature excess heat recovery in district heating systems : The potential of European Union metro stations
- 2020

Ingår i: Book of Abstracts. ; , s. 34-34

Konferensbidrag (övrigt vetenskapligt/konstnärligt)abstract
- This paper presents an assessment of the excess heat recovery potential from EU metro stations. The assessment is a sub-study on low temperature recovery opportunities, explored in the H2020 ReUseHeat project, and consists of spatial mapping of 1994 underground stations with quantitative estimates of sensible and latent heat, monthly and annually, attainable in rejected platform ventilation exhaust air. Being a low-temperature source, the assessment conceptually anticipates recovery of attainable heat with compressor heat pumps to facilitate the temperature increase necessary for utilisation in district heating systems. Further, the paper explores the influence on useful excess heat volumes from low-temperature heat recoveries when distributed at different temperature levels. The findings, which distinguishes available (resource) and accessible (useful) excess heat potentials, indicate an annual total EU28 available potential of ~21 PJ, characterised by a certain degree of seasonal temporality, and corresponding accessible potentials of ~40 PJ per year at 3rd generation distribution, and of ~31 PJ at anticipated 4th generation conditions. Despite lower accessible volumes, utilisation in 4th generation systems are naturally more energy efficient, since relatively less electricity is used in the recovery process, but also more cost-effective, since heat pumps, at lower temperatures, can be operated at capacities closer to design conditions and with less annual deviations.

- Autonomous driving relies on a variety of sensors, especially radars, which have unique robustness under heavy rain/fog/snow and poor light conditions. With the rapid increase of the amount of radars used on modern vehicles, where most radars operate in the same frequency band, the risk of radar interference becomes a compelling issue. This article analyzes automotive radar interference and proposes several new approaches that combine industrial and academic expertise toward the goal of achieving interference-free autonomous driving (AD). © IEEE.
