Peak oxygen uptake cut-points to identify children at increased cardiometabolic risk - The PANIC Study.

2019

We aimed to develop cut -points for directly measured peak oxygen uptake (VO2peak ) to identify boys and girls at increased cardiometabolic risk using different scaling methods to control for body size and composition. Altogether 352 children (186 boys, 166 girls) aged 9 – 11 years were included in the analyses. We measured VO2peak directly during a maximal cycle ergometer exercise test and lean body mass (LM) by bioelectrical impedance. We computed a sex - and age -specific cardiometabolic risk score (CRS) by summing important cardiometabolic risk factors and defined increased cardiometabolic risk as >1 standard deviation above the mean of CRS. Receiver operating characteristics curves wer…

Simultaneous production of furfural and levulinic acid from pine sawdust via acid-catalysed mechanical depolymerization and microwave irradiation

2019

Abstract In this work pine sawdust was converted into levulinic acid (LA) and furfural. Sawdust was first pre-treated with sulfuric acid-catalysed mechanical depolymerization. The conversion reactions were then performed with microwave heating at 180 °C. To enhance the furfural yield and the efficient separation of furfural and LA, a biphasic water-toluene reaction system was used. The effect of an additional catalyst, AlCl3, on the yield of LA and furfural was also studied. According to the results the pre-treatment method enhanced the yields of LA. In addition, due to the microwave heating the reaction times were short. Additional AlCl3 catalyst enhanced the LA yield, however excellent fu…

Mobilising Consumers for Food Waste Reduction in Finnish Media Discourse

2019

Raippalinna explores how consumers are mobilised for food waste reduction in media discourse. Food waste reduction initiatives are often criticised for putting the responsibility on individual consumers, but little research exists on the mobilisation of consumers in actual contexts. Through critical discourse analysis of media texts, Raippalinna investigates how the food waste problem and consumers are constructed in relation to each other in Finlands leading newspaper Helsingin Sanomat 2010–2017. The analysis demonstrates that the discourses of consumer mobilisation appear mostly as consumer education where the consumer’s role is to manage individual consumption and household practices. Th…

Children’s Emotions in Educational Settings: Teacher Perceptions from Australia, China, Finland, Japan and Spain

2019

The transition to formal education is a critical transition in children’s lives that has importance for socio-emotional and behavioral functioning. In the transition process, teachers are key players who work intensively with children and their families. This article focuses on teachers’ perceptions of children´s socio-emotional behavior during the transition from preschool to primary school. We collected qualitative teacher interviews from 112 teachers from five different countries—Australia, China, Finland, Japan and Spain. The research questions were: (1) How do teachers in the five countries perceive children’s abilities in expressing and regulating emotions. (2) How are children’s emot…

Sourcing practices in online journalism : an ethnographic study of the formation of trust in and the use of journalistic sources

2017

Arguably one of the most important factors of journalistic quality is careful source selection. Studies on online journalism have revealed working conditions which may lead to poor sourcing practices. This article seeks to answer the following questions: What sources do online journalists use, and how do they rationalize their sourcing practices? A total of 17 Finnish online journalists in 7 newsrooms were observed and interviewed over their practices of source searching, evaluation, and use. The study revealed five distinctive rationales of source use, which I call trust discourses: the ideological, the pragmatic, the cynically pragmatic, the consensual, and the contextual trust. Different…

Mediataitoja 2. -luokkalaisille opettamassa

2012

Mediakasvatuksen merkitys on korostunut 2000 luvulla. Media täyttää yhteiskunnan ja on mukana arjessamme monin tavoin. Lapset elävät mediatodellisuudessa, joka muuttuu koko ajan. Huoli internetin vaikutuksista lapsiin on lisännyt mediakasvatuksen tarvetta. Mediakasvatukseen alettiin kiinnittää huomiota jo 1970-luvulla ja vuoden 2004 perusopetuksen opetussuunnitelmaan sisällytettiin viestintä ja mediataito –aihekokonaisuus. Vaikka mediakasvatuksella ei ole oman oppiaineen asemaa, liittyy se läpäisyaiheena lähes kaikkien oppiaineiden opetukseen. Tässä tutkimuksessa perehdytään mediakasvatuksen toteuttamiseen peruskoulun toisella luokalla. Tarkoituksena oli selvittää ja kuvailla, kuinka lasten…

Data from: Analysis of personal and family factors in the persistence of attention deficit hyperactivity disorder: results of a prospective follow-up…

2016

Objectives: To study the course of ADHD during childhood and analyze possible personal and family predictor variables of the results. Method: Sixty-one children with ADHD who were between 6 and 12 years old at the baseline assessment were evaluated 30 months later (mean age at baseline: 8.70 ± 1.97; mean age at follow-up: 10.98 ± 2.19). Status of ADHD in follow-up was identified as persistent (met DSM-IV-TR criteria according to parents’ and teachers’ ratings), contextually persistent (met ADHD criteria according to one informant, and there was functional impairment) and remitted ADHD (with subthreshold clinical symptomatology). Associated psychological disorders of the three groups were an…
