Influence of self-assessment and conditional metaconceptual knowledge on students' self-regulation of intuitive and scientific conceptions of evolution
(2024-02-28)
Intuitive conceptions based on cognitive biases (teleology, anthropomorphism, and essentialism) often prove helpful in everyday life while simultaneously being problematic in scientific contexts. Nonetheless, students often have intuitive conceptions of scientific topics such as evolution. As potential approaches to enable students to selfregulate their conceptions in the context of evolution, we investigated the effectiveness of two instructional approaches that are based on metacognition and selfregulated learning: ...

Efficient numerical calculation of LYAPUNOV-exponents and stability assessment for quasi-periodic motions in nonlinear systems
(2024-04-05)
Investigating the stability of stationary motions is a highly relevant aspect when characterizing dynamical systems. For equilibria and periodic motions,well established theories and approaches exist to assess their stability: in both cases stability may be assessed using eigenvalue analyses of small perturbations. When it comes to quasi-periodic motions, such eigenvalue analyses are not applicable, since these motions can not be parameterized on finite time intervals. However, quasi-periodic motions can be densely ...

The relevance of proximity and work-related experience for the individual support for the expansion of power plants: An empirical analysis of wind, coal, and nuclear energy
(2024-06-14)
This paper empirically examines whether proximity to power plants and work-related experience in the wind, coal, and nuclear energy sectors are correlated with the individual support for the expansion of corresponding regional power plants. The data for this analysis stem from a large-scale computer-based survey among more than 3700 citizens in Germany. The econometric analysis with binary and ordered probit models reveals significantly positive correlations between work-related experience in a specific energy sector ...

The role of prior knowledge and need for cognition for the effectiveness of interleaved and blocked practice
(2023-07-11)
Interleaved practice combined with comparison prompts can better foster students’ adaptive use of subtraction strategies compared to blocked practice. It has not been previously investigated whether all students benefit equally from these teaching approaches. While interleaving subtraction tasks prompts students’ attention to the different task characteristics triggering the use of specific subtraction strategies, blocked practice does not support students in detecting these differences. Thus, low-prior-knowledge ...

The efficacy of spatio-temporal predictors in forecasting the risk of Cydia nigricana infestation
(2024-03-15)
The ability to estimate the risk of pest infestation can help farmers to reduce pesticide application and provide guidance that would result in better management decisions. This study tested whether different combinations of spatial and temporal risk factors may be used to predict the damage potential of pea moth, Cydia nigricana Fabricius (Lepidoptera: Tortricidae), a major pest in field pea (Pisum sativum L., Fabaceae). Over four consecutive years, the abundance of pea moth was monitored by placing pheromone traps ...

Enabling magnetic pulse welding for dissimilar tubular arrester cable joints
(2024-04-08)
Climate change exacerbates the need for resource-efficient and cost-effective production processes across manifold industries, including the field of electrical connections. This specific field is characterized by a conflict of objectives, i.e., weight reductions while maintaining joint strength and electrical conductivity. From a material point of view, the use of aluminum as a conductor material is suitable for this application, as it is lighter than copper, a classical conductor material. Electrical conductors are ...

Conditions and Effects of Norm Internalization
(2023-01-31)
Norm internalization refers to the process of adoption of normative beliefs by individuals, thus representing a link between individual and social change. However, there are several questions regarding norm internalization which need to be answered. These include understanding under which circumstances norm internalization does occur by considering the effects of internalizing either a certain norm or even conflicting norms. To investigate the conditions and effects of norm internalization, we developed a theoretical ...

Distinguishing fast change in social norms and slow change in personal norms in cooperative decision-making
(2024-05-30)
Psychological research on norms has shown that norms are highly relevant for individuals’ decision-making. Yet, there is so far little understanding of how norms change over time. Knowledge about how norms change may help better understanding their potential for as well as limitations in guiding decision-making and changing behavior. The present work investigated change in individuals’ cooperation norms. As an indicator of different underlying processes of norm change, the temporal dynamics of different types of norms ...

Dynamic tensile deformation behavior of AISI 316L stainless steel fabricated by laser-beam directed energy deposition
(2023-11-07)
The dynamic deformation behavior of metallic materials is the key to crash-safe design in many applications, e.g., in the automotive sector. However, in the field of additive manufacturing, dynamic deformation properties have only been scarcely studied. Based on the intrinsic interrelationships of process parameters, post-process heat treatments and the resulting microstructure, the present study seeks to provide a holistic overview of the dynamic tensile deformation properties of AISI 316L stainless steel, fabricated ...

Mathematical modelling of a latent heat storage: Influence of PCM thermal conductivity and enthalpy-temperature relationship
(2024-06-08)
Mathematical modelling of latent heat storage units is useful to calculate their thermal performance for integration in larger systems. This requires the input of thermophysical properties of the phase change material (PCM) used, but data provided by manufacturers or published in the literature is often incomplete and/or varies between sources. However, it is not clear to what extent an accurate knowledge of these properties, including their phase dependency, is necessary to obtain reliable calculations, especially ...
