The 920–900 Ma Bahia-Gangila LIP of the São Francisco and Congo cratons and link with Dashigou-Chulan LIP of North China craton : New insights from U-Pb geochronology and geochemistry

A widespread mafic sill and dyke unit (the Pedro Lessa suite) adjacent to the southeastern São Francisco (SF) craton (eastern South America) is dated as 940 ± 42 Ma, 912 ± 17 Ma, and 986 ± 64 Ma (based on combined ID-TIMS and LA-ICPMS analyses on baddeleyite grains) on the Santa Maria de Itabira gabbroic intrusion. These ages suggest membership in the previously defined ca. 920–900 Ma Large Igneou

The effects of immigration on economic growth – a literature study

Immigration has positive effects on productivity and economic growth. However, highly educated immigrants tend to contribute more to these effects. The literature suggests that immigrants boost Sweden’s performance in international trade but that Sweden may lose out on some of the positive effects of immigration on innovation. In order for Sweden to remain attractive to foreign experts it might be

Coevolution of deception and preferences: Darwin and Nash meet Machiavelli

We develop a framework in which individuals' preferences coevolve with their abilities to deceive others about their preferences and intentions. Specifically, individuals are characterised by (i) a level of cognitive sophistication and (ii) a subjective utility function. Increased cognition is costly, but higher-level individuals have the advantage of being able to deceive lower-level opponents ab

Harnessing local knowledge for scientific knowledge production : challenges and pitfalls within evidence-based sustainability studies

The calls for evidence-based public policy making have increased dramatically in the last decades, and so has the interest in evidence-based sustainability studies. But questions remain about what “evidence” actually means in different contexts and if the concept travels well between different domains of application. Some of the most relevant questions asked by sustainability studies are not, and

Extensive green roofs in Porto Alegre, Brazil : Effect on indoor thermal comfort in residential buildings

Brazil had a significant quantitative housing deficit of 7.7 million residences in 2015, especially in low-income housing. Traditionally, these projects have low levels of thermal insulation which can result in discomfort caused by warmth or cold. The residential sector is responsible for a significant part of the energy use in Brazil. A green roof, a rooftop system with the addition of vegetation

Disparities in colorectal cancer between Northern and SouthernSweden–a report from the new RISK North database

Background: Geographic cancer health disparities have been reported in Sweden. The disparities are not fully understood, but may be attributed to differences in exposure to risk factors as well as differences in health care, socioeconomics and demography. The aim of this study was to describe the new nationwide population based RISK North database and its potential by analysing health disparities

Enhanced constraints on the interior composition and structure of terrestrial exoplanets

Exoplanet interior modelling usually makes the assumption that the elemental abundances of a planet are identical to those of its host star. Host stellar abundances are good proxies of planetary abundances, but only for refractory elements. This is particularly true for terrestrial planets, as evidenced by the relative differences in bulk chemical composition between the Sun and the Earth and othe
