Complementarity in alliances: How strategic compatibility and hierarchy promote efficient cooperation in international security

open access: yesAmerican Journal of Political Science, EarlyView.
Abstract How can defense alliances reap the efficiency gains of working together when coordination and opportunism costs are high? Although specializing as part of a collective comes with economic and functional benefits, states must bargain over the distribution of those gains and ensure the costs of collective action are minimized.

Integration of epigenetics into ecotoxicology: insights and fundamental research needs

open access: yesBiological Reviews, EarlyView.
ABSTRACT Epigenetics refers to heritable changes in genome function that occur without direct alterations to the DNA sequence. A multitude of environmental contaminants can influence the epigenetic marks of a genome. Changes of epigenetic marks including DNA methylation, histone modifications, and non‐coding RNAs can induce alterations at the gene ...

A Modified Multi-Objective Particle Swarm Optimization Based on Levy Flight and Double-Archive Mechanism

open access: yesIEEE Access, 2019
In the past few decades, multi-objective particle swarm optimization (PSO) has increasingly attracted attention from scientists. To obtain a set of more accurate and well-distributed solutions, many variations of multi-objective PSO algorithms have been ...

A series of (un)fortunate events: Commercial bank interest rates and deposit reallocation during the Great Depression in the Netherlands

open access: yesThe Economic History Review, EarlyView.
Abstract During the global economic crisis of 1929–33, deposits in the Dutch commercial banking sector sharply declined as funds shifted to the government‐guaranteed Post Office Savings Bank and other savings institutions. Unlike earlier studies for neighbouring countries, we demonstrate that this shift was driven less by a flight to safety and more by

Exploring the interplay between small and large scales movements in a neotropical small mammal

open access: yesMovement Ecology
We record and analyze the movement patterns of the marsupial Didelphis aurita at different temporal scales. Animals trajectories are collected at a daily scale by using spool-and-line techniques and, with the help of radio-tracking devices, animals ...
