Problematische Ablehnungskonstruktionen
(2020-02-14)
Der Beitrag diskutiert rechtspopulistische, menschenfeindliche Rhetoriken zu Fragen von Sozialstaat und Erziehung kritisch. Anlass ist die Wahrnehmung, dass entspreche Sprachspiele zunehmend auch in der Praxis der Sozialen Arbeit artikuliert werden, ohne dass sie als solche identifiziert und kritisiert würden.
Rechte, nationale, xenophobische, antisemitische, rassistische, homophobe und andere Positionen aus dem Spektrum der gruppenbezogenen Menschenfeindlichkeit zu erkennen, fällt zunehmend schwerer. Zuweilen ...

Doppelspitzen: Notlösung, Heilsbringer oder innovatives Führungsmodell? Coaching für gelingende Führungstandems
(2021-03-25)
Doppelspitzen werden in der aktuellen Führungsdebatte kontrovers diskutiert. Wissenschaftliche Erkenntnisse zur Arbeit von Führungstandems sind rar. Bisherige Coachingkonzepte befassen sich schwerpunktmäßig mit dem Konfliktcoaching von Doppelspitzen. In dem vorliegenden Beitrag wird den Fragen nachgegangen, welche Gelingensfaktoren und Herausforderungen es bei geteilter Leitung gibt und wie die Potenziale von Führungstandems durch (präventives) Coaching gehoben werden können.

A Logic Based Approach to Finding Real Singularities of Implicit Ordinary Differential Equations
(2020-06-17)
We discuss the effective computation of geometric singularities of implicit ordinary differential equations over the real numbers using methods from logic. Via the Vessiot theory of differential equations, geometric singularities can be characterised as points where the behaviour of a certain linear system of equations changes. These points can be discovered using a specifically adapted parametric generalisation of Gaussian elimination combined with heuristic simplification techniques and real quantifier elimination ...

Barriers in Participative Water Governance: A Critical Analysis of Community Development Approaches
(2022-02-28)
Participatory approaches within development programs involving common-pool resources are intended to revive a community’s role in managing these resources. Certainly, to ensure the successful and equitable use of such resources, community participation is essential. However, in many cases, attempts at applying a participatory approach often fail to genuinely engage all subgroups within a community due to assumptions of homogeneity and a lack of understanding of the deep socio-political divisions between people. As a ...

Modelling and Simulation of Building Material Flows: Assessing the Potential for Concrete Recycling in the German Construction Sector
(2022-03-01)
The reuse and recycling of materials can make an important contribution to the conservation of natural resources in the sense of a circular economy. This applies in particular to high quality recycling, supporting the material use of waste and closing product cycles. The construction sector is the most important sector in terms of available volume of materials for recycling. However, the largest share of recycling (RC) materials goes predominantly into road construction and underground engineering. This research ...

Inter- and Intra-Individual Variation in the Behavior of Feed Intake on Nutrient Availability in Early Lactating Dairy Cows
(2021-12-24)
Since energetic deficits in dairy cows can only be reduced at an animal level, the objective of the present study was to determine the extent of variation in intake behavior within and between animals during early lactation, to explore the magnitude of interactions between feed intake, intake behavior and nutrient digestibility, and to identify levers for maximizing feed intake at the individual animal level. Feeding behavior, intake and nutrient digestibility of 28 German Holstein dairy cows, fed TMR with 7.0 MJ ...

Impacts of Climate Change on the Water Availability, Seasonality and Extremes in the Upper Indus Basin (UIB)
(2020-02-11)
Projecting future hydrology for the mountainous, highly glaciated upper Indus basin (UIB) is a challenging task because of uncertainties in future climate projections and issues with the coverage and quality of available reference climatic data and hydrological modelling approaches. This study attempts to address these issues by utilizing the semi-distributed hydrological model “Soil and water assessment tool” (SWAT) with new climate datasets and better spatial and altitudinal representation as well as a wider range ...

Development and Experiments on a Batch-Type Solar Roaster—An Innovative Decentralized System for Coffee Roasting
(2022-02-15)
About 70% of the harvested coffee is exported to the industrialized nations for value addition due to lack of processing and logistic facilities in developing coffee producer countries, thus leaving behind a marginal economic return for the growers. This research was conducted to investigate the roasting capacity of an innovatively developed batch-type directly solar radiated roasting system for the decentralized processing of coffee using solar energy. Central composite rotatable design (CCRD) was employed to design ...

A Survey on Cost Types, Interaction Schemes, and Annotator Performance Models in Selection Algorithms for Active Learning in Classification
(2021-12-14)
Pool-based active learning (AL) aims to optimize the annotation process (i.e., labeling) as the acquisition of annotations is often time-consuming and therefore expensive. For this purpose, an AL strategy queries annotations intelligently from annotators to train a high-performance classification model at a low annotation cost. Traditional AL strategies operate in an idealized framework. They assume a single, omniscient annotator who never gets tired and charges uniformly regardless of query difficulty. However, in ...

Comparison of Real and Simulated Fiber Orientations in Injection Molded Short Glass Fiber Reinforced Polyamide by X-ray Microtomography
(2021-12-22)
During injection molding of short glass fiber reinforced composites, a complex structure is formed due to the fiber movement. The resulting fiber orientation can be predicted using various simulation models. However, the models are known to have inadequacies andthe influence of process and model parameters is not clearly and comprehensively described. In this study, the aforementioned model and process parameters are investigated to determine the dependencies of the individual influences on the real and simulated ...
