The association between parental education, living arrangements and dietary habits among overweight and obese Norwegian children aged 6-10 years : “F…
2016
Masteroppgave folkehelsevitenskap - Universitetet i Agder 2016 Children´s dietary patterns have changed the passed decades. Children are more overweight and obese, and social inequalities related to this topic are discussed among all societies. The purpose of the master thesis was to explore the association between the sociodemographic factors parental education and living arrangements and the availability and intake of selected food items and total energy intake and macronutrient intake among overweight and obese Norwegian children aged 6-10 years. The thesis is an extension of the theory that is used in the article. This thesis begins with an introduction, which further expands to the ela…
Sample of weak blazars at mas resolution
2015
We started a follow-up investigation of the "Deep X-ray Radio Blazar Survey" objects with declination >-10{deg} to better understand the blazar phenomenon. We undertook a survey with the European Very Long Baseline Interferometry Network at 5GHz to make the first images of a complete sample of weak blazars, aiming at a follow-up comparison between high- and low-power samples of blazars. We observed 87 sources with the EVN at 5GHz during the period October 2009 to May 2013. The observations were correlated at the Max-Planck-Institut fuer Radioastronomie and at the Joint Institute for VLBI in Europe. The correlator output was analysed using both the AIPS and DIFMAP software packages. All of t…
Catching the radio flare in CTA 102
2013
Very Long Baseline Interferometry (VLBI) observations can resolve the radio structure of active galactic nuclei (AGN) and provide estimates of the structural and kinematic characteristics on parsec-scales in their jets. The changes in the kinematics of the observed jet features can be used to study the physical conditions in the innermost regions of these sources. We performed multifrequency multiepoch Very Long Baseline Array (VLBA) observations of the blazar CTA102 during its 2006 radio flare, the strongest ever reported for this source. These observations provide an excellent opportunity to investigate the evolution of the physical properties of blazars, especially during these flaring e…
Teachers' self-efficacy and the sources of efficacy: A cross-cultural investigation in Japan and Finland
2019
The study explores the extent and sources of Teachers’ Self-Efficacy (TSE) for inclusive practices among 261 Japanese and 1123 Finnish teachers. Measurement invariance was tested to ensure the chosen scales’ cross-cultural validity. In both countries, mastery experience was identified as the strongest of the four sources contributing uniquely to TSE. However, the two groups differed in how verbal persuasion predicted TSE. The findings indicate that the effects of the four sources on TSE depend strongly on sociocultural context, and that, in Japan, other sources may exert a powerful influence. Practical implications are discussed, with particular regard to teacher training programs. peerRevi…
Unravelling the Intertwined Atomic and Bulk Nature of Localised Excitons by Attosecond Spectroscopy
2021
The electro-optical properties of most semiconductors and insulators of technological interest are dominated by the presence of electron-hole quasi-particles, called excitons. The manipulation of excitons in dielectrics has recently received great attention, with possible applications in different fields including optoelectronics and photonics. Here, we apply attosecond transient reflection spectroscopy in a sequential two-foci geometry and observe sub-femtosecond dynamics of a core-level exciton in bulk MgF2 single crystals. Furthermore, we access absolute phase delays, which allow for an unambiguous comparison with theoretical calculations. Our results show that excitons surprisingly exhi…
An inverse problem for the minimal surface equation
2022
We use the method of higher order linearization to study an inverse boundary value problem for the minimal surface equation on a Riemannian manifold $(\mathbb{R}^n,g)$, where the metric $g$ is conformally Euclidean. In particular we show that with the knowledge of Dirichlet-to-Neumann map associated to the minimal surface equation, one can determine the Taylor series of the conformal factor $c(x)$ at $x_n=0$ up to a multiplicative constant. We show this both in the full data case and in some partial data cases.
Characterization of strong chain geometries by their automorphism group

A wide class of chain geometries is characterized by their automorphism group using properties of a distinguished involution.
