- Non-human primate neuroimaging is a rapidly growing area of research that promises to transform and scale translational and cross-species comparative neuroscience. Unfortunately, the technological and methodological advances of the past two decades have outpaced the accrual of data, which is particularly challenging given the relatively few centers that have the necessary facilities and capabilities. The PRIMatE Data Exchange (PRIME-DE) addresses this challenge by aggregating independently acquired non-human primate magnetic resonance imaging (MRI) datasets and openly sharing them via the International Neuroimaging Data-sharing Initiative (INDI). Here, we present the rationale, design, and procedures for the PRIME-DE consortium, as well as the initial release, consisting of 25 independent data collections aggregated across 22 sites (total = 217 non-human primates). We also outline the unique pitfalls and challenges that should be considered in the analysis of non-human primate MRI datasets, including providing automated quality assessment of the contributed datasets.

- Are some countries better equipped from the onset of a democratization process to become democracies? We compared successful and failed episodes of liberalization over the period 1900 to 2018 to examine if starting state influences the probability of successful democratization. We show that liberalization in autocracies was more likely to succeed in countries that had the advantage of a better starting point concerning political institutions, GDP, and education. These more privileged countries could also carry out key reforms more rapidly, and were able to do so even in areas in which they had no initial advantage. This reveals a "Matthew effect" in political science: to countries that already have, more is given. This is a novel observation in political science that has important implications for current methodologies and policies.

The monophyletic origin of delayed implantation in carnivores and its implications
- 2003
-
Ingår i: Evolution. ; 57:8, s. 1952-1956

Tidskriftsartikel (refereegranskat)abstract
- In several carnivores a newly fertilized egg enters diapause instead of being directly implanted into the uterus, a phenomenon called delayed implantation. Several hypotheses have been forwarded to explain the utility of this prolonged gestation period, but all of these depend on several independent origins of the character. Here, we conduct a phylogenetic reconstruction of the evolution of delayed implantation in the Carnivora that reveals one basal origin, with additional transitions all having occurred within the Mustelidae. Hence, previous hypotheses relating to its evolution become untestable. Further analyses revealed that the presence or absence of delayed implantation is unrelated to the timing of mating season and birth season. Instead, mustelids with direct implantation are smaller than those with delayed implantation. We therefore suggest that delayed implantation has been selected against in small species due to the relatively higher fecundity costs of a prolonged gestation period.
