Curriculum Emphases, Mathematics and Teaching Practices : Swedish Upper-Secondary Physics Teachers’ views

This article addresses physics teachers’ views about physics teaching in upper-secondary school. Their views have been investigated nationwide through a web-based questionnaire. The questionnaire has been developed based on several published instruments and is part of an ongoing project on the role of mathematics in physics teaching at upper-secondary school. The selected part of the results from

Harmonic morphisms on Lie groups and minimal conformal foliations of codimension two

Let G be a Lie group equipped with a left-invariant semi-Riemannian metric. Let K be a semisimple subgroup of G generating a left-invariant conformal foliation F of codimension two on G. We then show that the foliation F is minimal. This means that locally the leaves of F are fibres of a complex-valued harmonic morphism. In the Riemannian case, we prove that if the metric restricted to K is biinva

Ground geophysical measurements made on mine-tailings in Sweden. Case studies and lessons learnt

Ground-based geophysical surveys were conducted at eight mine-tailings repositories during 2021 and 2022 to help preparing an inventory of potential sources of critical raw materials in mine-waste. Geophysical methods included ERT, DCIP, RMT, and tTEM. In this study, we show results obtained on two of the sites as an example. Integration of models of electrical properties, geological observations,

Artificial intelligence in the information ecosystem: affordances for everyday information seeking

In this conceptual article, we argue that artificial intelligence (AI) systems are contributing to the generation of an environment of affordances for everyday information practices through which they exert influence on people and the planet in ways that often are left unrecognised. We illustrate our insights by focusing on the practices of information seeking in everyday life, suggesting that the

Temporal Changes in Concentrations of Lead and Other Trace Metals in Free-Ranging Eurasian Eagle Owls Bubo bubo in Sweden

Patterns of lead and other trace metals were examined in 122 Eurasian eagle owls Bubo bubo found dead in Sweden in the period 1978–2013. Environmental lead (Pb) has decreased over recent decades from reduced anthropogenic emissions but mortality by Pb poisoning is still frequently reported for avian raptors and scavengers exposed to Pb ammunition. One objective here was to determine if Pb concentr

Decision Support System in Hydrological Modeling - A case study in China

Generally speaking, Computer based numerical hydrological models have been playing a very central role during the last decades in dealing with water resources related problems. Various kinds of conceptual, physical and stochastical models have been developed. Perhaps the most important contribution of those models is the ability of simplifying and schematizing a complex problem in the nature and s

Self-reported fatigue in people with post COVID-19 : Impact on functioning in daily life, and associated factors – a cross-sectional study

Objective: To assess (i) the impact of self-reported fatigue on functioning in daily life, and (ii) the association with sociodemographics, physical capacity, and work ability among people with post-COVID-19. Design: A cross-sectional study. Subjects: Adults reporting post-COVID-19 symptoms for at least 2 months. Methods: Participants were recruited through social media and responded to an online

Numerical simulation of saltwater intrusion into Laccadive Island aquifers due to climate change

Saltwater intrusion is a serious environmental problem in coastal subsurface water systems around the world. In the development of subsurface water protection and rehabilitation strategies in the coastal areas, mathematical models play an important role. This paper discusses the role of subsurface water contamination models in planning, management and regulation, with a focus on generic and site s

Feedback Control in the Olivocerebellar Loop

About 40 years ago, a subpopulation of small neurons in the cerebellar nuclei was shown to project to the inferior olive, the source of the climbing fiber input to the cerebellum. This nucleo-olivary projection follows the zonal and probably also microzonal arrangement of the cerebellum so that closed loops are formed between the neurons in the olive, the cerebellar cortex, and the nuclei. Althoug

Symeon Metaphrastes and the Metaphrastic movement

The rewriting of hagiographical texts was a common activity in Byzantium. From at least the ninth century until the end of the Byzantine era, ecclesiastical and non-ecclesiastical writers turned repeatedly to this form of writing, in some cases evidencing an astonishingly prolific textual output. Metaphrasis is the only word found in Byzantine titles to indicate a rewritten text but never used to

Quality of health care around the time of childbirth during the COVID-19 pandemic : Results from the IMAgiNE EURO study in Norway and trends over time

Objective: To describe maternal perception of the quality of maternal and newborn care (QMNC) in facilities in Norway during the first year of COVID-19 pandemic. Methods: Women who gave birth in a Norwegian facility from March 1, 2020, to October 28, 2021, filled out a structured online questionnaire based on 40 WHO standards-based quality measures. Quantile regression analysis was performed to as

MAKING A MARKET : INFRASTRUCTURE, INTEGRATION, AND THE RISE OF INNOVATION

—We exploit exogenous variation arising from the historical roll-out of the Swedish railroad network across municipalities to identify the impacts of improved transport infrastructure on innovative activity. A network connection led to a local surge in patenting due to an increased entry and productivity of inventors. As the railroad network expanded, inventors in connected areas began to develop
