Universal thermodynamic properties of the intracluster medium over two decades in radius in the X-COP sample
2018
The hot plasma in galaxy clusters is expected to be heated to high temperatures through shocks and adiabatic compression. The thermodynamical properties of the gas encode information on the processes leading to the thermalization of the gas in the cluster's potential well as well as non-gravitational processes such as gas cooling, AGN feedback and kinetic energy. In this work we present the radial profiles of the thermodynamic properties of the intracluster medium (ICM) out to the virial radius for a sample of 12 galaxy clusters selected from the Planck all-sky survey. We determine the universal profiles of gas density, temperature, pressure, and entropy over more than two decades in radius…
A family based tailored counselling to increase non-exercise physical activity in adults with a sedentary job and physical activity in their young ch…
2011
Abstract Background Epidemiological evidence suggests that decrease in sedentary behaviour is beneficial for health. This family based randomized controlled trial examines whether face-to-face delivered counselling is effective in reducing sedentary time and improving health in adults and increasing moderate-to-vigorous activities in children. Methods The families are randomized after balancing socioeconomic and environmental factors in the Jyväskylä region, Finland. Inclusion criteria are: healthy men and women with children 3-8 years old, and having an occupation where they self-reportedly sit more than 50% of their work time and children in all-day day-care in kindergarten or in the firs…
Similarity Solutions and Collapse in the Attractive Gross-Pitaevskii Equation
2000
We analyse a generalised Gross-Pitaevskii equation involving a paraboloidal trap potential in $D$ space dimensions and generalised to a nonlinearity of order $2n+1$. For {\em attractive} coupling constants collapse of the particle density occurs for $Dn\ge 2$ and typically to a $\delta$-function centered at the origin of the trap. By introducing a new dynamical variable for the spherically symmetric solutions we show that all such solutions are self-similar close to the center of the trap. Exact self-similar solutions occur if, and only if, $Dn=2$, and for this case of $Dn=2$ we exhibit an exact but rather special D=1 analytical self-similar solution collapsing to a $\delta$-function which …
Lessons from Remote School and Work
2021
In autumn 2021, Covid-19 still has effect on our daily living and our possibilities to conduct everyday life practices such as work and studies. Current realities of ‘new normality’, based on remote work and restrictions of social activities, for example, are grounded on the vast changes that occurred when the pandemic began. In this text we take a look back to the period of school closures in Finland, and their effect on families’ daily practices related to children’s well-being and school work. We explore the impacts of remote school to learning opportunities to find ways to utilize the new, good practices of remote school also in the future. At the same time, we emphasize the significanc…
Relational analysis and the ethnographic approach : constructing preschool childhood
2021
This article elaborates the relational ontology in an ethnographic study. The aim is to seek relational construction of preschool practice and how children’s positions are constructed in it. The study is based on the understanding that ethnography and relational sociology share the idea that society emerges through repeated relations. The ontological thinking of relational sociology is applied in a micro-level analysis of three episodes from a Finnish preschool. We propose that relations appear in every single ethnographical episode and that carefully analysed repetitive relations can reveal a stabilised organisational structure. The analysis shows how the position of one child is structuri…
School performance of children from monogamous and polygamous families in Nigeria
2014
Scholastic success of Nigerian children coming from polygamous ( n = 50) and monogamous families ( n = 156) was compared. No differences between the two groups were observed across background variables of demographics, parental education and occupation, or family support for schooling. There were no differences in the Junior Secondary School Entrance Exam scores between the groups. However, children from polygamous families reported more difficulties in mathematics and English than their counterparts from monogamous families. The findings are discussed in relation to previous research.
The Mediating Role of Endocrine Factors in the Positive Relationship Between Fat Mass and Bone Mineral Content in Children Aged 9-11 Years: The Physi…
2022
IntroductionWe aimed to investigate whether the relationship between fat mass and bone mineral content (BMC) is mediated by insulin, leptin, adiponectin, dehydroepiandrosterone sulphate, testosterone and estradiol in children aged 9-11 years.Materials and MethodsWe utilised cross-sectional data from the Physical Activity and Nutrition in Children study (n = 230 to 396; 112 to 203 girls). Fat mass and BMC were assessed with dual-energy X-ray absorptiometry. Endocrine factors were assessed from fasted blood samples. We applied the novel 4-way decomposition method to analyse associations between fat mass, endocrine factors, and BMC.ResultsFat mass was positively associated with BMC in girls (ß…
The Positive Relationship between Moderate-to-Vigorous Physical Activity and Bone Mineral Content Is Not Mediated by Free Leptin Index in Prepubertal…
2021
Purpose: Moderate-to-vigorous physical activity (MVPA) positively influences bone mineral content (BMC) in prepubertal children, but it is unknown whether this relationship is partially mediated by free leptin index. The aim of this study was to examine whether the relationship between MVPA and total body less head (TBLH) BMC is mediated or moderated by free leptin index in prepubertal children. Methods: We performed a cross-sectional analysis on 401 children (194 girls) from baseline examinations of the Physical Activity and Nutrition in Childhood Study. We applied the four-way decomposition mediation analysis method to assess whether free leptin index, measured from fasted blood samples, …

Representation of Children’s Views in Finnish Newspaper Media Across Three Decades
2020
As the United Nations Convention on the Rights of the Child (UNCRC) celebrates its thirtieth anniversary, it is relevant to explore how understandings of children’s rights have appeared during these three decades. As a key public actor in society, the media provides an interesting field in which to study the salience of children’s rights in societal and public discussions. Thus, in this article, we examine how children’s views are represented in «Helsingin Sanomat», the main national newspaper of Finland, in 1997, 2007, and 2017. This examination is based on articles 12 and 13 of the UNCRC, where it is stated that children have the right to express themselves in all matters affecting them. …
