- Background: Problem gambling is a public health issue affecting both the gamblers, their families, their employers, and society as a whole. Recent law changes in Sweden oblige local and regional health authorities to invest more in prevention and treatment of problem gambling. The economic consequences of gambling, and thereby the potential economic consequences of policy changes in the area, are unknown, as the cost of problem gambling to society has remained largely unexplored in Sweden and similar settings. Methods: A prevalence-based cost-of-illness study for Sweden for the year 2018 was conducted. A societal approach was chosen in order to include direct costs (such as health care and legal costs), indirect costs (such as lost productivity due to unemployment), and intangible costs (such as reduced quality of life due to emotional distress). Costs were estimated by combining epidemiological and unit cost data. Results: The societal costs of problem gambling amounted to 1.42 billion euros in 2018, corresponding to 0.30% of the gross domestic product. Direct costs accounted only for 13% of the total costs. Indirect costs accounted for more than half (59%) of the total costs, while intangible costs accounted for 28%. The societal costs were more than twice as high as the tax revenue from gambling in 2018. Direct and indirect costs of problem gambling combined amounted to one third of the equivalent costs of smoking and one sixth of the costs of alcohol consumption in Sweden. Conclusions: Problem gambling is increasingly recognized as a public health issue. The societal costs of it are not negligible, also in relation to major public health issues of an addictive nature such as smoking and alcohol consumption. Direct costs for prevention and treatment are very low. A stronger focus on prevention and treatment might help to reduce many of the very high indirect and intangible costs in the future.

Book chapter (peer-reviewed)abstract
- This study investigates how much English Swedish-speaking children are able to extract from media prior to the instruction of English that takes place in school. The participants are 41 Swedish-speaking, 7 to 8-year-old children in grades 1 and 2. Their receptive knowledge of English grammar and vocabulary is tested using two picture-pointing tasks. For grammar, the ELIAS Grammar test is used (Kersten et al. 2010). Three morphological structures (plural -s, possessive -s and 3rd person singular -s) are targeted and analysed through the lens of Processability Theory (PT; Pienemann 1998, 2015). For vocabulary, the BVPS is used (Dunn et al. 1997). The results on grammar confirm the processability hierarchy predicted in PT, with a few exceptions. The remarks from the children reveal that they are able to discuss the linguistic forms and also give declarative rules. No signs of transfer from the L1 are found in the comprehension of morphology. However, the results on vocabulary indicate that the children use transfer. They rely on cognates and also on L1 phonology when trying to guess the meaning of the L2 words.

Low bandwidth network-rtk correction dissemination for high accuracy maritime navigation
- 2021
-
In: TransNav, International Journal on Marine Navigation and Safety of Sea Transportation. - : Faculty of Navigation, Gdynia Maritime University. - 2083-6473 .- 2083-6481. ; 15:1, s. 171-179

Journal article (peer-reviewed)abstract
- More than half of the incidents reported to EMSA relate to nautical events such as collision, groundings and contacts. Knowledge of accurate and high-integrity positioning is therefore not only a need for future automated shipping but a base for today’s safe navigation. Examples on accidents include Ever Given in the Suez Canal and HNoMS Helge Ingstad in Norway. A Network-RTK (NRTK) service can be used as an augmentation technique to improve performance of shipborne GNSS receivers for future positioning of manned and unmanned vessels in restricted areas, such as port areas, fairways, and inland water ways. NRTK service providers generate RTK corrections based on the observations of networks of GNSS reference stations which enables the users to determine their position with centimeter accuracy in real-time using a shipborne GNSS receiver. Selection of appropriate communication channels for dissemination of NRTK corrections data is the key to a secure positioning (localization) service. In PrePare-Ships project, the modern maritime communication system VDES (VHF Data Exchange System) is proposed to distribute SWEPOS (NRTK in Sweden) correction data to shipborne positioning modules. VDES is a very reliable technique and it is compatible with most onboard functionalities. In order to minimize the impact on the overall VDES data capacity in a local area, NRTK correction data shall only occupy a single VDES slot with a net capacity of 650 bytes. Update rates may vary but are preferably at 1Hz. However, NRTK correction data size changes instantly, depending on the number of visible GNSS satellites, and the data rate can therefore sometimes reach in excess of 1000 byte/s. In this study, a smart technique is proposed to reduce size of NRTK correction data to instantly adapt with the VDES requirements by choosing a combination of specific signals, satellites or even constellations such that the data rate is not more than 650 byte/s, and at the same time it achieves optimal positioning performance with the accuracy required by the PrePare-Ships project application.

Journal article (peer-reviewed)abstract
- OBJECTIVES: Physical inactivity and sedentary behaviour are associated with higher breast cancer risk in observational studies, but ascribing causality is difficult. Mendelian randomisation (MR) assesses causality by simulating randomised trial groups using genotype. We assessed whether lifelong physical activity or sedentary time, assessed using genotype, may be causally associated with breast cancer risk overall, pre/post-menopause, and by case-groups defined by tumour characteristics.METHODS: We performed two-sample inverse-variance-weighted MR using individual-level Breast Cancer Association Consortium case-control data from 130 957 European-ancestry women (69 838 invasive cases), and published UK Biobank data (n=91 105-377 234). Genetic instruments were single nucleotide polymorphisms (SNPs) associated in UK Biobank with wrist-worn accelerometer-measured overall physical activity (nsnps=5) or sedentary time (nsnps=6), or accelerometer-measured (nsnps=1) or self-reported (nsnps=5) vigorous physical activity.RESULTS: Greater genetically-predicted overall activity was associated with lower breast cancer overall risk (OR=0.59; 95% confidence interval (CI) 0.42 to 0.83 per-standard deviation (SD;~8 milligravities acceleration)) and for most case-groups. Genetically-predicted vigorous activity was associated with lower risk of pre/perimenopausal breast cancer (OR=0.62; 95% CI 0.45 to 0.87,≥3 vs. 0 self-reported days/week), with consistent estimates for most case-groups. Greater genetically-predicted sedentary time was associated with higher hormone-receptor-negative tumour risk (OR=1.77; 95% CI 1.07 to 2.92 per-SD (~7% time spent sedentary)), with elevated estimates for most case-groups. Results were robust to sensitivity analyses examining pleiotropy (including weighted-median-MR, MR-Egger).CONCLUSION: Our study provides strong evidence that greater overall physical activity, greater vigorous activity, and lower sedentary time are likely to reduce breast cancer risk. More widespread adoption of active lifestyles may reduce the burden from the most common cancer in women.

- ObjectiveTo explore associations between perinatal activity and survival in infants born at 22 and 23 weeks of gestation in Sweden. Design/SettingData on all births at 22 and 23 weeks' gestational age (GA) were prospectively collected in 2004-2007 (T1) or obtained from national registers in 2014-2016 (T2) and 2017-2019 (T3). Infants were assigned perinatal activity scores based on 3 key obstetric and 4 neonatal interventions. Main outcomeOne-year survival and survival without major neonatal morbidities (MNM): intraventricular haemorrhage grade 3-4, cystic periventricular leucomalacia, surgical necrotising enterocolitis, retinopathy of prematurity stage 3-5 or severe bronchopulmonary dysplasia. The association of GA-specific perinatal activity score and 1-year survival was also determined. Results977 infants (567 live births and 410 stillbirths) were included: 323 born in T1, 347 in T2 and 307 in T3. Among live-born infants, survival at 22 weeks was 5/49 (10%) in T1 and rose significantly to 29/74 (39%) in T2 and 31/80 (39%) in T3. Survival was not significantly different between epochs at 23 weeks (53%, 61% and 67%). Among survivors, the proportions without MNM in T1, T2 and T3 were 20%, 17% and 19% for 22 weeks and 17%, 25% and 25% for 23 weeks' infants (p>0.05 for all comparisons). Each 5-point increment in GA-specific perinatal activity score increased the odds for survival in first 12 hours of life (adjusted OR (aOR) 1.4; 95% CI 1.3 to 1.6) in addition to 1-year survival (aOR 1.2; 95% CI 1.1 to 1.3), and among live-born infants it was associated with increased survival without MNM (aOR 1.3; 95% CI 1.1 to 1.4). ConclusionIncreased perinatal activity was associated with reduced mortality and increased chances of survival without MNM in infants born at 22 and 23 weeks of GA.

Morphology and atomic structure of the sputtered and annealed Mo3Si and Cr3Si (110) surfaces
- 1994

Journal article (peer-reviewed)abstract
- Scanning tunneling microscopy was used to study the sputtered and annealed (110) surfaces of Mo3Si and Cr3Si. Both surfaces show extended and atomically flat terraces, but in the case of Mo3Si there is also a uniform distribution of Mo crystallites. This difference in morphology is discussed in terms of different preferential sputtering effects. In both cases, measured step heights show that the ideally bulk-truncated surfaces are either purely Si or metal terminated. Atomically resolved images suggest that the Mo3Si surface is Si terminated, but although no atomic resolution could be obtained for the Cr3Si surface, there are indications that this surface is instead metal terminated. © 1994 The American Physical Society.
