This chapter describes a case study of the role of mathematics in physics textbooks and in associated teacher-led lessons. The theoretical framework (Hansson L, Hansson Ö, Juter K, Redfors A. Sci Edu 24:615–644, 2015) used in the analysis focuses on relations communicated between three entities: Theoretical models, Mathematics and Reality. Previously the framework has been used for analysing class
This article discusses practical and theoretical aspects of real-time brain computer interface control methods based on Bayesian statistics. We investigate and improve the performance of automatic control and feedback algorithms of a reactive brain computer interface based on a visual oddball paradigm for faster statistical convergence. We introduce transfer learning using Gaussian mixture models,
Compassion fatigue (CF) in teachers is a novel concept with potentially high relevance in relation to the work-life demands on teachers today, and the associated challenges of long-term well-being and work-life satisfaction for the profession. CF was originally studied in mental health settings and captures the possible adverse effects on professionals’ empathic capacity and ability to care for cl
This study explores the bi-directional relationship between attractiveness and prosocial behavior. While it is known that we often expect attractive people to act more prosocial, this research also examines how someone's actions can affect how attractive we perceive them to be. In a pre-registered incentivized behavioral experiment (n = 250), using avatar pictures representative of previous player
The growth of plant-based food and drink substitutes has led to increased interest in oat-based milk substitute as a dairy milk alternative. Conventional liquid oat base (LOB) production results in a fibre-rich insoluble by-product and loss of valuable macronutrients. This study investigates the use of xylanase enzymes to release insoluble arabinoxylan (AX) fibre and employs different degrees of m
Modern combustion processes widely use exhaust gas recirculation, oxyfuel combustion, and other techniques that alter the concentration of diluent gases from that of the air. The dilution's impact on the laminar burning velocity, SL, is therefore a crucial effect that has been studied experimentally and numerically in the literature. However, an accurate fitting correlation with physical meanings
Bacteria are key organisms in energy and nutrient cycles, and predicting the effects of temperature change on bacterial activity is important in assessing global change effects. A changing in situ temperature will affect the temperature adaptation of bacterial growth in lake water, both long term in response to global change, and short term in response to seasonal variations. The rate of adaptatio
Background: Some endocrine disrupting chemicals (EDC), are “obesogens” and have been associated with overweight and obesity in children. Daily exposure to different classes of EDCs demands for research with mixtures approach. Objectives: This study evaluates the association, considering sex-specific effects, between prenatal exposure to EDC mixture and children's body fat at seven years of age. Me
Background: Previous population-based studies investigating the relationship between physical activity and the gut microbiota have relied on self-reported activity, prone to reporting bias. Here, we investigated the associations of accelerometer-based sedentary (SED), moderate-intensity (MPA), and vigorous-intensity (VPA) physical activity with the gut microbiota using cross-sectional data from th
Background and objective: Surveillance following resection with curative intent of pancreatic cancer varies widely, and supporting evidence is limited. Recurrence is although frequent, not at least during the first 2 years. Surveillance may be costly, but evidence on how this influences overall survival is not fully elucidated. Methods, Results: There are reports implying that signs of biological
Solar cells based on silicon are successfully harvesting solar energy in established and increasingly widespread solar panels. However, their efficiency is limited by the Shockley–Queisser limit. For certain applications where high efficiency is the key figure of merit, the use of multi-junction solar cells is desirable.III–V multi-junction solar cells exhibit the highest efficiencies achieved to
Online activities can serve as tools for criminal opportunities and arenas for victimhood, but they can also function as reality constructions embedded in social control. One example of the latter is online sleuthing, primarily focused on dramatizing and disentangling offline crimes. This article relies on data from an ethnographic project conducted on the Swedish platform Flashback and analyzes p
We used Swedish national-register data (N = 2,828,777) to examine divorce and its associated patterns of family genetic-risk scores (FGRSs; personalized measures of genetic risk inferred from diagnoses in relatives) across 10 psychiatric disorders: major depression, anxiety disorders, obsessive compulsive disorder, bipolar disorder, schizophrenia, anorexia nervosa, alcohol use disorder, drug use d
This doctoral thesis consists of three independent research papers. All papers are empirical and cover the area of international trade and environmental economics, with particular focus on Swedish manufacturing firms. The first paper investigates how carbon offshoring could contribute to cleaner production. Using Swedish firm-product level data from 2005-2014, combined with instrumental variable a
The recently discovered selective glomerular hypofiltration syndromes have increased interest in the actual elimination of molecules in the human kidney. In the present study, a novel human model was introduced to directly measure the single-pass renal elimination of molecules of increasing size. Plasma concentrations of urea, creatinine, C-peptide, insulin, pro-BNP, β2-microglobulin, cystatin C,
