Flourishing through adventure learning: A (semi)cautionary tale

open access: yesBritish Educational Research Journal, EarlyView.
Abstract Studies suggest that adventure learning can develop children's cognitive skills and promote social and emotional learning. However, evidence is needed as to whether the design of adventure learning—school‐based or external/residential—plays a role in that development/promotion, and whether learning gains are maintained.

Deciphering Nazi Racial Sorting: The Challenges of Attempting a Big Data Approach

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
In 2019 I started analyzing a large set of “race cards” preserved in the German Federal Archives (Bundesarchiv). These cards document anthropometric measurements performed by SS experts during WWII in the territories occupied by the Nazi regime. Applying a big data approach, my goal was to use those cards to study the inner dynamics of the racial ...

Early Modern Amateur Botany and Historical Biodiversity: An Interdisciplinary Approach to the Herbarium Ruperti (1698–1705)

open access: yesBerichte zur Wissenschaftsgeschichte, EarlyView.
The Herbarium Ruperti, compiled by the Lutheran theologian Georg Andreas Ruperti and containing ca. 1300 plants, represents one of the earliest comprehensive collections documenting the flora of northern Germany before the emergence of systematic botanical surveys.

Existence and multiplicity of solutions for a differential inclusion problem involving the p(x)-Laplacian

open access: yesElectronic Journal of Differential Equations, 2010
In this article we consider the differential inclusion $$displaylines{ -hbox{div}(| abla u|^{p(x)-2} abla u)in partial F(x,u) quadhbox{in }Omega,cr u=0 quad hbox{on }partial Omega }$$ which involves the $p(x)$-Laplacian.

Existence and multiplicity of solutions for Klein–Gordon–Maxwell systems with sign-changing potentials

open access: yesAdvances in Difference Equations, 2019
In this paper, we study the following nonlinear Klein–Gordon–Maxwell system: {−Δu+V(x)u−(2ω+ϕ)ϕu=f(x,u)+λh(x)|u|q−2u,x∈R3,Δϕ=(ω+ϕ)u2,x∈R3,(Pλ) $$ \textstyle\begin{cases} -\Delta u+ V(x)u-(2\omega +\phi )\phi u = f(x,u)+\lambda h(x) \vert u \vert ^{q-2}u,

Hot and cold deserts as eco‐evolutionary arenas for understanding plant resistance to multiple abiotic stressors

open access: yesBiological Reviews, EarlyView.
ABSTRACT During their long evolutionary history, land plants have evolved a range of adaptations to different abiotic stressors. These help explain present‐day diversity and distribution patterns, as well as the potential resilience of natural and agricultural systems to a changing climate. Most previous research has focused on adaptation to individual
