The feasibility of working memory tablet tasks in predicting scholastic skills in classroom settings
Cognitive assessment in natural group settings facilitates data collection but poses threats to the validity. In this study, tabletâbased working memory (WM) tasks, the counting span, and reading span were used in predicting 12âyearâold children's (N = 837) scholastic skills and fluid intelligence in a classroom with environmental noise. WM tasks had excellent internal consistency, correlated with scholastic skills, and accounted for more of the variance in cognitive performance (grade point average, fluid intelligence, scholastic skills) compared with individually administered (n = 190) digit span task. Furthermore, the multilevel analysis revealed that compared with the classrooms with no noise, when naturally occurring speech or nonspeech types of environmental noises were present during assessment, WM scores or the reliability estimates were not lower. In contrast, when both types of noises were present, the relationships between some of the WM and achievement scores were even stronger. Thus, assessments in natural classroom contexts may promote revealing the individual differences in WM.Peer reviewe
Parental financial support : A safety net for young adults with debt problems
Parental financial support benefits young adults in societies with decreasing welfare-state support and a pattern of early home-leaving. This article focuses on the association between young adults' debt problems and parental financial support: the extent to which indebted young adults receive financial help from their parents. We also investigate the extent to which specific benefits are associated with debt problems or parental financial support. The data were gathered in an online survey conducted among 18-to-35-year-old Finns (n = 1,019). The results revealed, first, that many parents safeguard their indebted adult children's lives by means of financial support and second, that heavy cash-welfare-benefit users are particularly likely to receive parental financial support. Our analysis also revealed that the prevalence of debt problems as well as of parental financial support were especially high among those who had received social assistance, sickness benefit or labour-market subsidy within the previous 12 months. In a society open to new social risks as well as to debt problems, young people who lack financial support from their parents have a rockier transition to adulthood than those who receive support.Peer reviewe
Low prevalence of zoonotic multidrug-resistant bacteria in veterinarians in a country with prudent use of antimicrobials in animals
The occurrence of multidrug-resistant zoonotic bacteria in animals has been increasing worldwide. Working in close contact with livestock increases the risk of carriage of these bacteria. We investigated the occurrence of extended-spectrum beta-lactamase (ESBL) and plasmidic AmpC beta-lactamase producing Enterobacteriaceae (ESBL/pAmpC-PE) and livestock-associated methicillin-resistant Staphylococcus aureus (LA-MRSA) in Finnish veterinarians (n = 320). In addition to microbiological samples, background information was collected. Bacterial whole genome sequencing was performed to deduce sequence types (STs), spa types and resistance genes of the isolates. In total, 3.0% (9/297) of the veterinarians carried ESBL producing Escherichia coli, with one ESBL producing E. coli isolate producing also AmpC. Seven different STs, sequences of several different plasmid groups as well as several different bla(ESBL/pAmpC )genes existed in different combinations. No carbapenemase or colistin resistance genes were detected. MRSA was detected in 0.3% (1/320) of the samples. The strain belonged to LA-MRSA clonal complex (CC) 398 (ST398, spa type 011, lacking Panton-Valentine leukocidin genes). In conclusion, this study shows low carriage of multidrug-resistant zoonotic bacteria in Finnish veterinarians. However, finding LA-MRSA for the first time in a sample from a veterinarian in a country with prudent use of animal antimicrobials and regarding the recent rise of LA-MRSA on Finnish pig farms, a strong recommendation to protect people working in close contact with animals carrying LA-MRSA CC398 is given. Further studies are needed to explain why the prevalence of LA-MRSA in veterinarians is lower in Finland than in other European countries.Peer reviewe
Significant decrease in the rate of fatal alcohol poisonings in Finland validated by blood alcohol concentration statistics
Background: Alcohol may cause death directly by acute poisoning, as well as induce illnesses or accidents that lead to death. Our research question was whether the current decreasing trend in acute fatal alcohol poisonings in Finland is a real phenomenon or an artefact caused by possible changes in the process of determining the cause of death. Methods: All cases in the national post-mortem toxicology database in which the underlying cause of death was acute alcohol poisoning in 1987-2018 were investigated in terms of blood alcohol concentration (BAC), age and gender. The number of acute alcohol poisonings was compared to the number of deaths from alcohol induced illness in the post-mortem toxicology database. Results: A total of 12 126 acute alcohol poisoning cases were retrieved. Between 2004 and 2017 the number of acute alcohol poisonings decreased 60.1 %. At the same time the number of alcohol induced illnesses in the study material remained stable or decreased marginally. The median BAC in all acute alcohol poisonings was 3.2 g/kg. The annual median BAC values showed a small but significant decrease over the study period. The proportion of women in acute alcohol poisonings increased significantly over the study period, from 17.1%-22.3%. Women were on average 2.5 years older than men. Conclusions: On grounds of the BAC statistics and supporting evidence, we conclude that the significant decrease in the number of fatal alcohol poisonings is true and likely reflects changes in the overall consumption of alcohol.Peer reviewe

Removing these residues from a harvest site reduces the carbon stock of the forest compared with conventional stem-only harvest because less litter in left on the site. The indirect carbon dioxide (CO 2) emission from producing bioenergy occur when carbon in the logging residues is emitted into the atmosphere at once through combustion, instead of being released little by little as a result of decomposition at the harvest sites. In this study (1) we introduce an approach to calculate this indirect emission from using logging residues for bioenergy production, and (2) estimate this emission at a typical target of harvest residue removal, i.e. boreal Norway spruce forest in Finland. The removal of stumps caused a larger indirect emission per unit of energy produced than the removal of branches because of a lower decomposition rate of the stumps. The indirect emission per unit of energy produced decreased with time since starting to collect the harvest residues as a result of decomposition at older harvest sites. During the 100 years of conducting this practice, the indirect emission from average-sized branches (diameter 2cm) decreased from 340 to 70kgCO 2eq.MWh -1 and that from stumps (diameter 26cm) from 340 to 160kgCO 2eq.MWh -1. These emissions are an order of magnitude larger than the other emissions (collecting, transporting, etc.) from the bioenergy production chain. When the bioenergy production was started, the total emissions were comparable to fossil fuels. The practice had to be carried out for 22 (stumps) or four (branches) years until the total emissions dropped below the emissions of natural gas. Our results emphasize the importance of accounting for land-use-related indirect emissions to correctly estimate the efficiency of bioenergy in reducing CO 2 emission into the atmosphere.Peer reviewe

The version of record is available online at doi: 10.1111/j.1757-1707.2011.01124.x © 2011 Blackwell Publishing LtdBioenergy from forest residues can be used to avoid fossil carbon emissions, but removing biomass from forests reduces carbon stock sizes and carbon input to litter and soil. The magnitude and longevity of these carbon stock changes determine how effective measures to utilize bioenergy from forest residues are to reduce greenhouse gas (GHG) emissions from the energy sector and to mitigate climate change. In this study, we estimate the variability of GHG emissions and consequent climate impacts resulting from producing bioenergy from stumps, branches and residual biomass of forest thinning operations in Finland, and the contribution of the variability in key factors, i.e. forest residue diameter, tree species, geographical location of the forest biomass removal site and harvesting method, to the emissions and their climate impact. The GHG emissions and the consequent climate impacts estimated as changes in radiative forcing were comparable to fossil fuels when bioenergy production from forest residues was initiated. The emissions and climate impacts decreased over time because forest residues were predicted to decompose releasing CO2 even if left in the forest. Both were mainly affected by forest residue diameter and climatic conditions of the forest residue collection site. Tree species and the harvest method of thinning wood (whole tree or stem-only) had a smaller effect on the magnitude of emissions. The largest reduction in the energy production climate impacts after 20 years, up to 62%, was achieved when coal was replaced by the branches collected from Southern Finland, whereas the smallest reduction 7% was gained by using stumps from Northern Finland instead of natural gas. After 100 years the corresponding values were 77% and 21%. The choice of forest residue biomass collected affects significantly the emissions and climate impacts of forest bioenergy.Peer reviewe
