Deutungen von Bildung frühpädagogischer Fachkräfte
(2021-08-20)
Kindertageseinrichtungen gelten als Bildungsinstitutionen und leisten einen wesentlichen Beitrag zur Gestaltung des Aufwachsens von Kindern in Deutschland. Dabei spielen die frühpädagogischen Fachkräfte als Gestalter_innen und Ermöglicher_innen von Bildungsprozessen für Kinder eine entscheidende Rolle. Der Beitrag nimmt ihre Vorstellungen von Bildung und worauf sich diese gründen in den Blick.

Detecting Careless Responding in Survey Data Using Stochastic Gradient Boosting
(2021-04-19)
Careless responding is a bias in survey responses that disregards the actual item content, constituting a threat to the factor structure, reliability, and validity of psychological measurements. Different approaches have been proposed to detect aberrant responses such as probing questions that directly assess test-taking behavior (e.g., bogus items), auxiliary or paradata (e.g., response times), or data-driven statistical techniques (e.g., Mahalanobis distance). In the present study, gradient boosted trees, a ...

Tensions in sustainable warehousing: including the blue-collar perspective on automation and ergonomic workplace design
(2020-05-14)
In many industrial countries, demographic changes towards an aging society go hand in hand with the need for ergonomic workplaces. Therefore, it is necessary to rethink workplace designs and work processes, particularly in industrial professions, such as logistics. As logistics activities are still characterized by a high amount of manual effort, they represent a suitable field for gaining empirical insights into the implementation of automation and ergonomic practices to inform social sustainable warehousing logistics ...

Smallholders’ Challenges: Realizing Peri-Urban Opportunities in Bengaluru
(2021-09-10)
Urban expansion creates potential for increased incomes among previously rural smallholders from sources other than traditional agriculture. Harnessing this potential, however, requires investments into agricultural upgrading or non-farm activities. The article addresses the question concerning to what extent these investments are realised in the peri-urban space of Bengaluru. Its answers are based on a review of the literature and extensive field surveys in two differentially developed districts assessing the ...

Different Visualizations Cause Different Strategies When Dealing With Bayesian Situations
(2020-08-21)
People often struggle with Bayesian reasoning. However, previous research showed that people’s performance (and rationality) can be supported by the way the statistical information is represented. First, research showed that using natural frequencies instead of probabilities as the format of statistical information significantly increases people’s performance in Bayesian situations. Second, research also revealed that people’s performance increases through using visualization. We have built our paper on existing ...

Perceptions of Vegan Food among Organic Food Consumers Following Different Diets
(2021-08-31)
This article identifies consumer segments for vegan food by analysing perceptions of vegan food among food organic consumers following different diets: vegans, vegetarians, former vegetarians, flexitarians, and omnivores. The analysis is based on responses to a quantitative consumer survey for which 503 participants were recruited from customers at German grocery stores by quota sampling according to diet and region. From the responses to an open-ended question eliciting the participants’ associations with vegan food, ...

Combining Genetic Gain and Diversity in Plant Breeding: Heritability of Root Selection in Wheat Populations
(2021-11-18)
To increase the resilience of agroecological farming systems against weeds, pests, and pathogens, evolutionary breeding of diversified crop populations is highly promising. A fundamental challenge in population breeding is to combine effective selection and breeding progress while maintaining intraspecific diversity. A hydroponic system was tested for its suitability to non-destructively select root traits on a population level in order to achieve genetic gain and maintain diversity. Forty wheat progenies were selected ...

Karin Bock, Nina Göddertz, Franziska Heyden, Miriam Mauritz (Hrsg.) (2019). Zugänge zur Kinderladenbewegung
(2020-06-16)
Der Sammelband entstand als neueste Publikation aus dem Projekt „Die Kinderladenbewegung: Biographische Auswirkungen und gesellschaftspolitische Einflüsse institutioneller Erziehungsarrangements“ und rahmt diesen Forschungszusammenhang auf unkonventionelle Art. Ihn kennzeichnet vor allem ein sehr breites Spektrum an Artikeln, die 1968 und die Kinderladenbewegung aus unterschiedlichsten Perspektiven beleuchten, womit er auch dem Anspruch der Herausgeber_innen, die „(…) Vielschichtigkeit und Verschiedenheit der Zugänge ...

Negotiating weights for burden sharing rules in international climate negotiations: an empirical analysis
(2020-11-03)
We have collected data from a world-wide survey among COP delegates to empirically investigate preferences for certain burden sharing rules among key groups in a setting that reflects the possibility of observing concessions from negotiating partners. In our survey, the participants had the opportunity to select and combine up to eight (pre-defined) burden sharing rules and to assign relative weights to the selected rules in their preferred bundle. We examine whether such a mechanism helps to overcome the currently ...

Comparison of Spaceborne and UAV-Borne Remote Sensing Spectral Data for Estimating Monsoon Crop Vegetation Parameters
(2021-04-20)
Various remote sensing data have been successfully applied to monitor crop vegetation parameters for different crop types. Those successful applications mostly focused on one sensor system or a single crop type. This study compares how two different sensor data (spaceborne multispectral vs unmanned aerial vehicle borne hyperspectral) can estimate crop vegetation parameters from three monsoon crops in tropical regions: finger millet, maize, and lablab. The study was conducted in two experimental field layouts (irrigated ...
