TL;DR: Molecular phylogenetic analysis, calibrated with fossils, resolves the time frame of the mammalian radiation and diversification analyses suggest important roles for the Cretaceous Terrestrial Revolution and KPg mass extinction in opening up ecospace that promoted interordinal and intraordinal diversification, respectively.
Abstract: Previous analyses of relations, divergence times, and diversification patterns among extant mammalian families have relied on supertree methods and local molecular clocks. We constructed a molecular supermatrix for mammalian families and analyzed these data with likelihood-based methods and relaxed molecular clocks. Phylogenetic analyses resulted in a robust phylogeny with better resolution than phylogenies from supertree methods. Relaxed clock analyses support the long-fuse model of diversification and highlight the importance of including multiple fossil calibrations that are spread across the tree. Molecular time trees and diversification analyses suggest important roles for the Cretaceous Terrestrial Revolution and Cretaceous-Paleogene (KPg) mass extinction in opening up ecospace that promoted interordinal and intraordinal diversification, respectively. By contrast, diversification analyses provide no support for the hypothesis concerning the delayed rise of present-day mammals during the Eocene Period.

TL;DR: The general finding that rats without a hippocampus were impaired on those tasks that required the utilization of spatial and contextual information stands in contrast with the spared performance that was found in learning about and handling (even complex) nonspatial information.

TL;DR: In this article, the authors examined the effects of international corporate entrepreneurship (ICE) efforts on company performance and found that the payoff from ICE is moderated by executives' perceptions of the hostility of their firm's international business environment.

TL;DR: The authors compared variation in the replicability of 13 classic and contemporary effects across 36 independent samples totaling 6,344 participants and found that the results of these experiments are more dependent on the effect itself than on the sample and setting used to investigate the effect.
Abstract: Although replication is a central tenet of science, direct replications are rare in psychology. This research tested variation in the replicability of 13 classic and contemporary effects across 36 independent samples totaling 6,344 participants. In the aggregate, 10 effects replicated consistently. One effect – imagined contact reducing prejudice – showed weak support for replicability. And two effects – flag priming influencing conservatism and currency priming influencing system justification – did not replicate. We compared whether the conditions such as lab versus online or US versus international sample predicted effect magnitudes. By and large they did not. The results of this small sample of effects suggest that replicability is more dependent on the effect itself than on the sample and setting used to investigate the effect.
