Wine quality under integrated, organic and biodynamic management using image-forming methods and sensory analysis
(2021-12-24)
Background and aims
The image-forming methods copper chloride crystallization, capillary dynamolysis and circular chromatography are presented as an instrument for assessing wine quality. Wine quality of samples from a long-term field trial comparing integrated, organic and biodynamic management were investigated by using image-forming methods and sensory analysis.
Methods and results
Concerning the image-forming methods copper chloride crystallization, capillary dynamolysis and circular chromatography, the images ...

Feed Quality and Feeding Level Effects on Faecal Composition in East African Cattle Farming Systems
(2021-02-22)
Simple Summary
Sub-Saharan cattle are often exposed to a feed reduction caused by a seasonal lack of forage, which was investigated in the first experiment. The supplementation of roughage-based diets with sweet potato vine silage and urea molasses blocks is recommended to improve the growth of heifers, in particular, which was investigated in the second experiment. Across all data, the fungal C/bacterial C ratio was positively related to nitrogen and negatively to neutral detergent fiber concentrations in feces. ...

Flickering presentations do affect the judgment of learning but not the learning outcome
(2023-05-22)
We examined whether visual disfluency, as elicited by presenting text on flickering slides, affects learning positively and the global judgment of learning (JOL) negatively. Participants (N = 202 in Experiment 1, between-subjects design; N = 53 in Experiment 2, within-subjects design) saw in an online session multiple slides including textual information that they had to learn. The slides were presented either fluently or disfluently, that is, interrupted by rapid presentations of black slides, evoking a flickering ...

Time Series Optimization-Based Characteristic Curve Calculation for Local Reactive Power Control Using Pandapower-PowerModels Interface
(2023-05-29)
Local reactive power control in distribution grids with a high penetration of distributed energy resources (DERs) will be essential in future power system operation. Appropriate control characteristic curves for DERs support stable and efficient distribution grid operation. However, the current practice is to configure local controllers collectively with constant characteristic curves that may not be efficient for volatile grid conditions or the desired targets of grid operators. To address this issue, this paper ...

Detecting Greenwashing! The Influence of Product Colour and Product Price on Consumers’ Detection Accuracy of Faked Bio‑fashion
(2023-04-04)
While there exists recent research about greenwashing in the context of branding and product packaging as well as advertising, we investigated greenwashing detection depending on the cues colour and price of the product itself. We hypothesized: The more
the product cues fit to the mental representation of the corresponding category-prototype of bio (or non-bio) products, the more likely consumers classify the product to that category, are confident with the classification-decision and actually get deceived. In two ...

New Distributed Optimization Method for TSO-DSO Coordinated Grid Operation Preserving Power System Operator Sovereignity
(2023-06-16)
Electrical power system operators (SOs) are free to realize grid operations according to their own strategies. However, because resulting power flows also depend on the actions of neighboring SOs, appropriate coordination is needed to improve the resulting system states from an overall perspective and from an individual SO perspective. In this paper, a new method is presented that preserves the data integrity of the SOs and their independent operation of their grids. This method is compared with a non-coordinated ...

Legal challenges of an open web index
(2021-03-16)
Calls for a European “third way” in matters of digital technology need to be put into action to achieve an actual change of the status quo. To achieve autonomy in the digital sphere, European alternatives to digital services and products need to be established. However, such efforts must also extend to the level of information technology infrastructure. To that end, decentralized indexing of the internet could significantly help to strengthen Europe’s digital sovereignty. Nevertheless, legal challenges need to be ...

How to conduct systematic literature reviews in management research: a guide in 6 steps and 14 decisions
(2023-05-12)
Systematic literature reviews (SLRs) have become a standard tool in many fields of management research but are often considerably less stringently presented than other pieces of research. The resulting lack of replicability of the research and conclusions has spurred a vital debate on the SLR process, but related guidance is scattered across a number of core references and is overly centered on the design and conduct of the SLR, while failing to guide researchers in crafting and presenting their findings in an impactful ...

Spatial and Temporal Dynamics of Urban Wetlands in an Indian Megacity over the Past 50 Years
(2020-02-17)
Asian megacities have attracted much scientific attention in the context of global urbanization, but few quantitative studies analyze wetland transformation in the rural–urban interface. With its rampant growth and transformation from a tree-lined “Garden City” to a busy megalopolis with often-blocked highways and large built-up areas, Bengaluru (Karnataka, S-India) is a good example for assessing how urbanization has led to the acute degradation of wetlands. We therefore investigated long-term land cover and wetland ...

Rurbanity: a concept for the interdisciplinary study of rural–urban transformation
(2023-05-20)
Along with climate change, population growth, and overexploitation of natural resources, urbanisation is among the major global challenges of our time. It is a nexus where many of the world’s grand challenges intersect, and thus key to sustainable development. The widespread understanding of urbanisation as a successive and unidirectional transformation of landscapes and societies from a rural to an urban state is increasingly questioned. Examples from around the globe show that ‘the rural’ and ‘the urban’ are not ...
