Land cover transitions and effects of transhumance on available forage biomass of rangelands in Benin
(2021-11-30)
This study examined the effects of transhumance pressure on total abavoe-ground biomass and forage availability on rangelands in Benin. We also investigated the implications of land cover transitions on rangelands over a 31-year period. Our work was carried out in three regions of Benin representing distinct phytogeographic regimes: Ketou, Tchaourou, and Sinende. Ground-truthing and biomass sampling of the herbaceous and phanaerophyte strata were carried out between the 2016 peak vegetation period and the onset of ...

Von Lefort zu Mouffe. Populismus als Moment und Grenze radikaler Demokratie
(2021-06-10)
In diesem Beitrag werden Chantal Mouffes jüngste Interventionen für den Linkspopulismus zum Anlass für eine theoretische Reflexion über das Spannungsverhältnis zwischen Populismus und radikaler Demokratie genommen. Im Lichte der radikalen Demokratietheorien Claude Leforts, Jacques Rancières, Ernesto Laclaus und Chantal Mouffes, der Populismustheorie Laclaus sowie der einschlägigen Rezeption wird argumentiert, dass der Populismus sowohl konstitutives Moment als auch Grenze eines radikalen Demokratieverständnisses ...

Angebot, Nutzung und Ertrag von Konzeptwechseltexten zu Neuromythen bei angehenden Biologielehrkräften
(2021-04-27)
Lehrkräftebildung hat das Ziel, Studierende zu Fachleuten für das Lehren und Lernen auszubilden. Empirische Studien zeigen jedoch sowohl bei angehenden als auch praktizierenden Lehrkräften eine hohe Zustimmung zu Fehlvorstellungen zum Thema Gehirn und Lernen – sogenannten Neuromythen. In der vorliegenden Studie wird in einem Mixed-Model-Design (N = 40) mit quantitativen und qualitativen Forschungsmethoden und vor dem theoretischen Hintergrund eines Angebots-Nutzungs-Modells untersucht, inwiefern sich durch eine ...

Quo Vadis Conferences in the Business and Information Systems Engineering (BISE) Community After Covid
(2021-07-06)
The global Covid-19 pandemic has not only influenced the way we work and collaborate on our research but also how we present and exchange novel contributions at scientific conferences. Governmental lockdowns and (inter)-national travel restrictions have forced conference organizers to move from offline conference venues to virtual platforms quickly. Our discipline, the Business & Information Systems Engineering (BISE) community, is an interdisciplinary field involving the more conference-driven computer sciences and ...

3D Arrangement of Magnetic Particles in Thin Polymer Films Assisted by Magnetically Patterned Exchange Bias Layer Systems
(2021-10-31)
The possibility to arrange and embed magnetic micro- and nanoparticles in thin polymer film systems using flat magnetically patterned substrate templates is investigated. In contrast to self-organized particle rows forming by applying a homogeneous magnetic field, particles adapt to the magnetic field landscape of the substrate's magnetic pattern prior to polymer crosslinking. Crosslinking then fixes the particle positions in the polymer. The process is tested for composites of hydrophobic polydimethylsiloxane (PDMS) ...

Phospholipid fatty acids in soil—drawbacks and future prospects
(2021-12-21)
The current opinion and position paper highlights (1) correct assignation of indicator phospholipid fatty acids (PLFA), (2) specificity and recycling of PLFA in microorganisms, and (3) complete extraction and detection of PLFA. The straight-chain PLFA 14:0, 15:0, 16:0, and 17:0 occur in all microorganisms, i.e., also in fungi and not only in bacteria. If the phylum Actinobacteria is excluded from the group of Gram-positive bacteria, all remaining bacteria belong to the bacterial phylum Firmicutes, which should be ...

Nonlocal damage modelling for finite element simulations of ductile steel sheets under multiaxial loading
(2021-12-14)
The finite element simulation of forming processes or vehicle crash scenarios involves multiaxial loading conditions in general. Thereby, damage and failure in ductile steel sheets is triggered by void growth under hydrostatic tensile loading or by void elongation within a narrow band under shear dominated loading. These different damage mechanisms are considered by a stress state dependent continuum damage model. The damage initiation and failure are represented by a critical and a failure strain. Both are HOSFORD-COULOMB ...

IMEX-DG Schemes for Advection-Diffusion Problems using Term-based or Domain-based IMEX Splitting
(2021-12-14)
IMEX partitioning may be based on a decomposition of the computational domain into two subgrids by implicitly discretizing the unknowns on the smallest cells while explicit time stepping is applied to moderately sized elements. Alternatively, advection-diffusion IMEX splitting applies implicit time discretization only to the viscous terms while inviscid terms are discretized explicitly. Analytical investigations have shown that a careful choice of both the specific IMEX scheme and the particular DG approach yield an ...

Force distribution in self-tapping screws: experimental investigations with fibre Bragg grating measurement screws
(2021-08-17)
The pull-out resistance of fully threaded, self-tapping screws under axial loading has been investigated intensively in the past. Actual design models are based mainly on empirical data because the detailed interaction between the screw thread and the surrounding timber member remains unclear and might depend on the test set-up. An innovative screw sensor with 19 internal fibre Bragg gratings (FBGs) was developed to measure the forces along the screw axis. The screw diameter was 12 mm and the maximum embedding length ...
