Objectives To estimate the risk of clinically diagnosed knee osteoarthritis (OA) after different types of knee injuries in young adults. Methods In a longitudinal cohort study based on population-based healthcare data from Skåne, Sweden, we included all persons aged 25-34 years in 1998-2007 (n=149 288) with and without diagnoses of knee injuries according to International Classification of Disease

This note describes how research on the link between economic openness and government size has changed over time. Early interpretations suggested that countries develop welfare states to compensate for volatility caused by economic openness (the compensation hypothesis). Recent findings have cast doubts on this interpretation. For example, more open economies are on average not more volatile, and

The CRISPR/Cas9 system is a versatile tool for functional genomics and forward genetic screens in mammalian cells. However, it has been challenging to deliver the CRISPR components to sensitive cell types, such as primary human hematopoietic stem and progenitor cells (HSPCs), partly due to lentiviral transduction of Cas9 being extremely inefficient in these cells. Here, to overcome these hurdles,

The financial crisis started in 2007–2008, initially in the US, but its consequences have been felt throughout the global economy. However, its effects were far from uniform. While parts of Asia and Africa continued to grow fast, Europe experienced a large set back. This paper emphasizes three important factors: differences across countries in technological development; differences in capacities t

This introduction to the biology of standing waters integrates the effects of abiotic constraints and biotic interactions at both the population and community level, and examines how the distribution and success of different organisms in this freshwater habitat can be explained and predicted

Paper on Allan Kastrup and his role in Swedish public diplomacy in the United States 1945-1970.

Scholars and policy makers consider knowledge accumulation a major driver of growth and regional development. During the past two decades, the geography of innovation literature has provided a rich and detailed account of the underlying processes of regional knowledge production. More recently, a growing body of empirical literature has analysed the specific knowledge bases of regions and their ev

We theorize that three distinct structures of democratic constraint explain why more democratic dyads do not engage in military conflict with each other. We build on earlier theories that focused on electoral and horizontal accountability. We add a new dimension—the social accountability provided by an active civil society. Using several new measures from the Varieties of Democracy (V-Dem) data se

The first study of this volume looks for reminiscences of Dies Irae in Chopin’s works. A great number of allusions and affinities are found in the preludes as well as in Chopin’s output. The study also yields insights into Chopin’s composition method. These intertextual findings are used in an attempt to establish the extra-musical content of the Second Ballade. Five preludes – A minor, E minor, B

Tha amplitudes for the Kℓ4 decays are calculated to next-to-leading order in Chiral Perturbation Theory. These are then compared with the available experimental results on these decays. The values of the parameters L1, 2, 3 previously determined from ππ scattering are compared with those obtained here. A short overview of the determination of the parameters of Chiral Perturbation Theory is include
