Acceptability, reach and implementation of a training to enhance teachers’ skills in physical activity promotion
2020
This is a pre-print of a published study: Renko, E., Knittle, K., Palsola, M. et al. Acceptability, reach and implementation of a training to enhance teachers’ skills in physical activity promotion. BMC Public Health 20, 1568 (2020). https://doi.org/10.1186/s12889-020-09653-x Background: In order to achieve real-world impacts, successful behavior change interventions need to be scaled up and broadly implemented. Implementation is challenging however, and the factors influencing successful implementation are not fully understood. This study describes the nationwide implementation of a complex theory-based program to promote physical activity and reduce sedentary behavior in vocational school…
Melting point, molecular symmetry and aggregation of tetrachlorobenzene isomers: the role of halogen bonding
2018
Tetrachlorobenzenes represent one of the best known, but not yet fully understood, group of isomers of the structure–melting point relationship. The differences in melting temperatures of these structurally related compounds were rationalized in terms of the hierarchy and nature of formed noncovalent interactions, and the molecular aggregation that is influenced by molecular symmetry. The highest melting point is associated with the highly symmetric 1,2,4,5-tetrachlorobenzene isomer. The structures of less symmetrical 1,2,3,4-tetrachlorobenzene and 1,2,3,5-tetrachlorobenzene, determined at 270 and 90 K, show a distinct pattern of halogen bonds, characterized by the different numbers and typ…
The division of domestic work among dual-career and other dual-earner couples in Finland
2015
This study compares the division of domestic work among dual-career and other dual-earner couples. We examine whether gender attitudes, relative resources and working time explain the differences between dual-career and other dual-earner couples. We define dual-career couples as those in which both spouses are professionals and/or managers. The division of housework is important for these couples because of the intense pressures of work. We hypothesise that domestic work is more equally shared among dual-career couples than among other dual-earner couples. The quantitative analyses are based on the Finnish data from the 2010 European Social Survey (N = 493). The qualitative data consist of …
“I want to speak like the other people” : Second language learning as a virtuous spiral for migrant women?
2017
This article contributes to scholarship on migrant women’s second language (L2) education in North America and Europe. Questioning reductionist understandings of the relationship between female migrants, their receiving communities and L2 education, the authors consider existing literature as well as their own qualitative work to investigate the challenges, opportunities and agency of migrant women. Weaving together and thematically presenting previous scholarship and qualitative data from interviews, participant observations and classroom recordings from a mixed-gender L2 adult migrant classroom in Austria and an all-women L2 migrant classroom in the United States, they trouble conceptuali…
The Bishop-Phelps-Bollobás property for bilinear forms and polynomials
2014
For a $\sigma$-finite measure $\mu$ and a Banach space $Y$ we study the Bishop-Phelps-Bollobás property (BPBP) for bilinear forms on $L_1(\mu)\times Y$, that is, a (continuous) bilinear form on $L_1(\mu)\times Y$ almost attaining its norm at $(f_0,y_0)$ can be approximated by bilinear forms attaining their norms at unit vectors close to $(f_0,y_0)$. In case that $Y$ is an Asplund space we characterize the Banach spaces $Y$ satisfying this property. We also exhibit some class of bilinear forms for which the BPBP does not hold, though the set of norm attaining bilinear forms in that class is dense.
Decoherence without entanglement and quantum Darwinism
2020
It is often assumed that decoherence arises as a result of the entangling interaction between a quantum system and its environment, as a consequence of which the environment effectively measures the system, thus washing away its quantum properties. Moreover, this interaction results in the emergence of a classical objective reality, as described by quantum Darwinism. In this Rapid Communication, we show that the idea that entanglement is needed for decoherence is imprecise. We propose a dynamical mixing mechanism capable of inducing decoherence dynamics on a system without creating any entanglement with its quantum environment. We illustrate this mechanism by introducing a simple and exactl…
Great expectations: Learning the boundaries of design rights
2019
We present a case study of an increase in design right filings and concurrent design right litigations in an industry that previously had little experience of design right protection. The motives for and outcomes of filing, and how these changed over time are discussed. We go on to explore the events, which offered the decision makers opportunities to update their beliefs about the scope of design right protection. We find that filing motives changed from specific protection goals to freedom to operate over time. We also find that the actors faced several, but sometimes contradictory, learning opportunities. There are two types of learning relating to the usage of design rights: 1) learning…
The fractional Calderón problem: Low regularity and stability
2017
The Calder\'on problem for the fractional Schr\"odinger equation was introduced in the work \cite{GSU}, which gave a global uniqueness result also in the partial data case. This article improves this result in two ways. First, we prove a quantitative uniqueness result showing that this inverse problem enjoys logarithmic stability under suitable a priori bounds. Second, we show that the results are valid for potentials in scale-invariant $L^p$ or negative order Sobolev spaces. A key point is a quantitative approximation property for solutions of fractional equations, obtained by combining a careful propagation of smallness analysis for the Caffarelli-Silvestre extension and a duality argumen…
THE ANTIOXIDANT PROPERTIES OF PHENOLIC MOLECULES IN RELATIONSHIP WITH THE pH OF ENVIRONMENT REACTION
2011
THE ANTIOXIDANT PROPERTIES OF PHENOLIC MOLECULES IN RELATIONSHIP WITH THE pH OF ENVIRONMENT REACTION Some epidemiological evidence suggests beneficial effects on human health from a diet rich in fruit, vegetables and certain types of beverages such as tea and wine (1,2). These compounds do not have nutritive properties but they have a functional role in the human organism. Some studies have investigated the effect of pH on the antioxidant properties of polyphenols (3,4) and have reported that the pH-dependent behaviour is related to hydroxyl deprotonation. However, these studies did not compare the antioxidant activity of various classes of polyphenols and did not take into account the acid…
Monotone generalized nonlinear contractions and fixed point theorems in ordered metric spaces
2011
The purpose of this paper is to present some fixed point theorems for T -weakly isotone increasing mappings which satisfy a generalized nonlinear contractive condition in complete ordered metric spaces. As application, we establish an existence theorem for a solution of some integral equations.
