Abstract We give an overview of current research questions pursued in connection with an ongoing project on nominal classification systems in Africa, with a particular focus on Niger-Congo. We first introduce our cross-linguistically applicable methodological approach w...

Past research has greatly improved our understanding of palaeoenvironmental changes in the Lake Baikal Region, but at the same time has indicated intra-regional variations in this vast study area. Here we present a new AMS-dated late glacial-middle Holocene (ca. 13,500-...

The role of fathers in (co-)parenting their children among refugee and disadvantaged families in low and middle-income countries (LMICs) remains poorly understood. This study sought to examine the associations among mothers' perceptions of their husband's involvement (h...

In line with the social investment principle, becoming a parent should lead to more mature behaviour and an increase in conscientiousness, agreeableness, and emotional stability. However, previous research provided mixed results that do not support this idea. Here, we ...

Abstract During childhood, the brain is gradually converging to the efficient functional architecture observed in adults. How the brain's functional architecture evolves with age, particularly in young children, is however, not well understood. We examined the functiona...

The on-going COVID-19 crisis demonstrates how interlinked and networked our globalized society has become Overall, the special issue advances our knowledge of nodes in global networks by further investigating the particularities of such nodes, drawing conclusions on bot...

We study contracting between a public good provider and users with private valuations of the good. We show that, once the provider extracts the users' private information, she benefits from manipulating the collective information received from all users when communicati...

The International Monetary Fund and the World Bank ascribe to impartiality in their mandates. At the same time, scholarship indicates that their decisions are disproportionately influenced by powerful member states. Impartiality is seen as crucial in determining Interna...

This paper describes an estimator of the additive components of a nonparametric additive model with a known link function. When the additive components are twice continuously differentiable, the estimator is asymptotically normally distributed with a rate of convergence...

In this paper we present closed form solutions of some discounted optimal stopping problems for the maximum process in a model driven by a Brownian motion and a compound Poisson process with exponential jumps. The method of proof is based on reducing the initial problem...
