TL;DR: In this article, the international 14C calibration curves for both the Northern and Southern Hemispheres, as well as for the ocean surface layer, have been updated to include a wealth of new data and extended to 55,000 cal BP.

TL;DR: The Southern Hemisphere SHCal04 radiocarbon calibration curve has been updated with the addition of new data sets extending measurements to 2145 cal BP and including the ANSTO Younger Dryas Huon pine data set as mentioned in this paper.

TL;DR: The authors reconstructed past temperatures for seven continental-scale regions during the past one to two millennia and found that the most coherent feature in nearly all of the regional temperature reconstructions is a long-term cooling trend, which ended late in the nineteenth century.

TL;DR: In this article, the Southern Hemisphere curve (SHCal20) is proposed to estimate the mean Southern Hemisphere offset to be 36 ± 27 14C yrs older than the Northern Hemisphere offset, based upon a comparison of Southern Hemisphere tree-ring data compared with contemporaneous Northern Hemisphere data.

TL;DR: The concept of disruptive innovation has gained considerable currency among practitioners despite widespread misunderstanding of its core principles as mentioned in this paper. But subsequent empirical research has rarely engaged with its key theoretical arguments, and this inconsistent reception warrants a thoughtful evaluation of research on disruptive innovation within management and strategy.
