Take it or leave it? Investigating the ambivalence and willingness to pay for suboptimal fruits and vegetables among organic consumers in Germany
(2022-10-06)
Organic fruits and vegetables are often visually “suboptimal” because organic farming uses neither pesticides nor synthetic fertilisers to improve the cosmetic appearance of the produce. Despite the organic sector's natural and sustainable image, such foods often never reach the market or are left on the shelf, greatly increasing food waste. The current work hypothesised that an important factor in the rejection of suboptimal food is consumers' experience of ambivalence regarding these products. Data were collected ...

Sharing and Space‐Commoning Knowledge Through Urban Living Labs Across Different European Cities
(2022-08-25)
While the growing commodification of housing and public spaces in European cities is producing urban inequalities affecting mostly migrant and vulnerable populations, there are also manifold small-scale neighbourhood-based collaborative processes that seek to co-produce shared urban resources and contribute to more resilient urban developments. As part of the ProSHARE research project that investigates conditions in which sharing takes place and can be expanded to less-represented populations, we focus here on sharing ...

Effects of Mangosteen Peel Phenolic Compounds on Tilapia Skin Collagen-Based Mineralized Scaffold Properties
(2022-09-16)
A proper valorization of biological waste sources for an effective conversion into composites for tissue engineering is discussed in this study. Hence, the collagen and the phenolic compound applied in this investigation were extracted from waste sources, respectively, fish industry rejects and the peels of the mangosteen fruit. Porous scaffolds were prepared by combining both components at different compositions and mineralized at different temperatures to evaluate the modifications in the biomimetic formation of ...

Das Wohlbefinden von Kindern als elterliches Konstrukt
(2022-07-03)
Der Beitrag beschäftigt sich mit der Perspektive von Eltern auf das Wohlbefinden ihrer Kinder unter dem Eindruck der pandemiebedingten Schließungen von Kindertageseinrichtungen. Auf Basis qualitativ-rekonstruktiver Analysen kann gezeigt werden, wie sich die Wahrnehmungen der eigenen und der kindlichen Handlungsmächtigkeit bedingen. In Verbindung mit der Verfügbarkeit des Zugangs zur sog. Notbetreuung beeinflusst dieses Verhältnis das Belastungserleben.

Multi-Task Autoencoders and Transfer Learning for Day-Ahead Wind and Photovoltaic Power Forecasts
(2022-10-30)
Integrating new renewable energy resources requires robust and reliable forecasts to ensure a stable electrical grid and avoid blackouts. Sophisticated representation learning techniques, such as autoencoders, play an essential role, as they allow for the extraction of latent features to forecast the expected generated wind and photovoltaic power for the next seconds up to days. Thereby, autoencoders reduce the required training time and the time spent in manual feature engineering and often improve the forecast ...

Prediction of total carotenoids, color, and moisture content of carrot slices during hot air drying using non-invasive hyperspectral imaging technique
(2022-02-04)
The objective of this paper was to evaluate the performance of Partial Least Square Regression (PLSR) model and to assess the statistical agreement between two different measurement techniques, that is, Vis–NIR hyperspectral imaging (HSI) and standard laboratory methods for quality evaluation of dried carrots throughout the hot-air drying process. Carrots at commercial maturity of 3.5 months after planting were harvested in two seasons (2017 and 2018) and dried in a convective hot air dryer at 50°C, 60°C, and 70°C. ...

Spatial patterns of urbanising landscapes in the North Indian Punjab show features predicted by fractal theory
(2022-02-02)
Understanding and governing human settlement patterns is a major challenge of the urban age. While rural settlements emerge as parts of agricultural landscapes, cities typically evolve in economically strategic locations, and over time form hierarchical systems of cities. Purposeful planning and the collective, self-organized behavior of the inhabitants interact in the development of regional settlement patterns. Since self-organizing systems often produce fractal patterns in nature, this study combines approaches ...

Biodynamic compost effects on soil parameters in a 27-year long-term field experiment
(2022-10-27)
Background
Soil samples were taken after 27 years from a long-term field experiment to study the effects of composted pure cattle farmyard manure (FYM) and two FYM treatments with biodynamic preparations on soil chemical and microbiological properties.
Methods
Soil organic carbon (SOC), total nitrogen, basal respiration, fungal ergosterol, microbial biomass C (MBC) and nitrogen (MBN) were analyzed in a 6-field crop rotation system, conducted as a randomized block design with six replicates. The multi-substrate-induced ...

Mean girls, queen bees and iron maidens? Female leadership and accusations of workplace bullying
(2022-10-11)
We examined whether female leaders would be evaluated less favorably compared to male leaders regarding workplace bullying. Previous research has demonstrated that women violating prescriptive gender norms of communality experience backlash, and that female leaders are stereotyped of having a communality deficit. Building on that, we hypothesized (1) more moral outrage against and (2) more intentions to punish a female leader compared to a male leader. We further hypothesized (3) the accusations of ...

The combined application of nitrogen and biochar reduced microbial carbon limitation in irrigated soils of West African urban horticulture
(2022-07-16)
Background:
Intensive wastewater irrigated urban horticulture in sub-Saharan West Africa receives high nutrient inputs, which lead to large gaseous and leaching losses. The addition of biochar to the usually sandy soils may reduce these losses and improve the habitat conditions for soil microorganisms. Two similar experiments focused on crop yields and nutrient balances have been carried out over a 2-year period in semi-arid Ouagadougou, Burkina Faso, and in sub-humid Tamale, Ghana, representing to some extent ...
