This paper examines the distributive effects of personal income taxation in Sweden, the United Kingdom, and the United States during the first half of the 20th century. We estimate the evolution of marginal and average effective tax rates across the income distribution and calculate the corresponding indices of progressivity and redistribution. Our results show that redistribution through income t
In situ catalysis studies typically correlate catalytic function and majority surface structures, but neglect that difficult-to-detect minority structures might govern catalysis. Here we use an oscillating CO:O2 gas composition to drive structural oscillations on a catalytically active Pd(100) surface and collect X-ray photoelectron spectroscopy data at high measurement frequency to demonstrate th
Boken är en översiktlig syntes av det egyptiska pyramidbyggandet, från de första mastaborna till pyramidkonstruktionerna i Nubien.
Sustainable Aviation Fuels (SAF) are the most promising strategy for reducing the carbon emissions of aviation in the near term, but their combustion behavior is not well understood compared to conventional fuels. This work investigates how different properties of SAF may lead to different emergent combustion behavior by targeting a small set of very distinct fuels. The investigation is carried ou
Den visuella omvärlden kan vara dynamisk och föränderlig vilket skapar otydlighet i sensorisk information. Dessutom genererar hjärnans neurala aktivitet ”brus” som bidrar till denna otydlighet. Trots dessa svårigheter kan det visuella systemet i hjärnan bearbeta denna otydliga information och skapa en kontinuerlig och stabil visuell upplevelse, vilket låter oss navigera i omvärlden med trygghet. EThe visual environment can be dynamic and often changes from one moment to the next, causing sensory input to be noisy and uncertain. In addition, internal noise from neural activity in the brain contributes to this uncertainty. Despite these challenges, the brain’s visual system adeptly processes this noisy and uncertain information, creating a stable and continuous perceptual experience that all
När vi nu står inför en samhällelig strukturomvandling med digitalisering och AI-utveckling är många oroliga för att arbeten kommer att försvinna. Det kommer de säkert, men det kan också tillkomma nya jobb – om vi lär oss av historien och spelar våra kort rätt, skriver välfärdsforskaren Andreas Bergh och Joakim Wernberg, lektor i teknik och samhälle.
Green Hydrogen has been hailed as a game changer in climate actions, yet both global hydrogen markets and governance frameworks remain underdeveloped. The EU aims to pioneer a regulatory pathway, embedding hydrogen into its decarbonization governance framework. Centered on renewable hydrogen, the EU moves beyond “color-coding” technical classifications towards an emission-intensity-based legal def
This is a poster presentation of the project RIGHydro for the MissionGreenFuels Annual Meeting 2025. The project RIGHydro is funded by the Innovation Fund Denmark.The Project "Regulatory Innovation to Incentivize Green Hydrogen" (RIGHydro) aims to contribute to the deployment of green hydrogen as a key component of the green transition in Denmark, the EU and beyond. Through an analysis of the late
In this chapter, we explore the integration of sustainable entrepreneurship education in the context of circular entrepreneurship ecosystems, highlighting the necessity of shifting from traditional profit-centric models towards ones that emphasize sustainability and circular economy principles. We critique current educational practices for overlooking environmental and ethical considerations and a
This paper theorizes conditions accelerating experiential learning within venture creation programs (VCPs). Traditionally, experiential learning theory views learning as a slow and self-directed process. In contrast, VCPs offer time-compressed, enterprise-oriented training structured around predetermined plans and schedules. Our theorizing shifts the primary focus from cyclical movements (“loops”)
Phospholipids are amphiphilic molecules that self-assemble into organized structures such as bilayers and vesicles when dispersed in aqueous solutions. This property in addition to their biocompatibility, biodegradability, and natural abundance in high titres makes phospholipids highly attractive as formulation excipients for a wide range of biological and technical applications. However, isolatin
Imminent crises and the much-needed transition to a sustainable society bring knowledge about de-implementation to the fore. Using case studies with inspiration from process tracing, and with tools from Charles Tilly’s theory on Durable inequality, we identify mechanisms that generate inequality and counteract the implementation of recovery – and strength-based practices.

Introduction: Anti–glomerular basement membrane (GBM) disease is caused by pathogenic antibodies usually targeting the noncollagenous domain of the α3 chain of type IV collagen and frequently presents as rapidly progressive glomerulonephritis and diffuse alveolar hemorrhage (DAH). Rapid reduction of these antibodies is imperative for kidney survival and the mainstay of therapy is the combination o
Techniques based on intense photon beams from synchrotrons present unique opportunities for characterizing semiconductor materials, devices and processes. This is based on the unrivaled brightness in a broad wavelength range from infrared to hard X-rays. Synchrotron based methods can answer wide ranging questions in research and technology, and have seen an increase in use over many years as more
Background The risk of perinatal death and severe neonatal morbidity increases : gradually after 41 weeks of pregnancy. We evaluated maternal and perinatal outcomes after a national shift from expectancy and induction at 42+0 weeks to a more active management of late-term pregnancies in Sweden offering induction from 41+0 weeks or an individual plan aiming at birth or active labour no later than 4
Gobiernos y empresas argumentan que las inversiones en energía eólica contribuyen al desarrollo sustentable, combaten el cambio climático y promueven la protección del medioambiente. Sin embargo, el impacto de la expansión a gran escala para la producción de energía renovable en territorios de pueblos autóctonos parece desafiar tales argumentos. Este capítulo presenta dos conceptos claves para dis
