Tests and academic cheating: do learning tasks influence cheating by way of negative evaluations?
(2020-04-27)
Desirable difficulties like tests were often shown to increase long-term learning. However, due to the complexity and difficulty of such tasks, they are also argued to result in negative consequences like stress, anxiety, pressure, frustration, or negative evaluations. In other studies, such consequences were, in turn, often found to increase dishonest behaviour. Hence, the present work tests the assumptions that tests as difficult learning tasks, contrary to reading, lead to more negative evaluations of the learning ...

Exploiting ferroelectric and ferroelastic effects in piezoelectric energy harvesting: theoretical studies and parameter optimization
(2021-02-18)
While piezoelectric energy harvesting typically focuses on converting mechanical into electrical energy on the basis of the linear reversible piezoelectric effect, the potential of exploiting the non-linear ferroelectric effect is investigated theoretically in this paper. Due to its dissipative nature, domain switching, on the one hand, is basically avoided in order to prevent mechanical energy from being converted into heat. However, the electrical output, on the other hand, is augmented due to the increased change ...

A Stable N-Heterocyclic Silylene with a 1,1′-Ferrocenediyl Backbone
(2020-10-15)
The N-heterocyclic silylene [{Fe(η⁵-C₅H4-NDipp)₂}Si] (1DippSi, Dipp=2,6-diisopropylphenyl) shows an excellent combination of pronounced thermal stability and high reactivity towards small molecules. It reacts readily with CO₂ and N₂O, respectively affording (1DippSiO₂)₂C and (1DippSiO)₂ as follow-up products of the silanone 1DippSiO. Its reactions with H₂O, NH₃, and FcPH₂ (Fc=ferrocenyl) furnish the respective oxidative addition products 1DippSi(H)X (X=OH, NH₂, PHFc). Its reaction with H₃BNH₃ unexpectedly results in ...

On the Finite Orthogonality of q-Pseudo-Jacobi Polynomials
(2020-08-08)
Using the Sturm–Liouville theory in q-difference spaces, we prove the finite orthogonality of q-Pseudo Jacobi polynomials. Their norm square values are then explicitly computed by means of the Favard theorem.

Changes in Dairy Products Value Chain in Georgia
(2020-07-22)
The livestock sector, as a part of the traditional food system in Georgia, occupies a considerable portion of the national economy. Though smallholder farmers are the key suppliers at the primary stage in the food value chain, the empowerment of smallholder farmers in the dairy production system in Georgia is a questionable matter. This research study reports the results of changes in the dairy sector in Georgia (Caucasus) after becoming independent from the Soviet Union (literature survey) and how these changes are ...

Articulating Body, Territory, and the Defence of Life: The Politics of Strategic Equivalencing between Women in Anti‐Mining Movements and the Feminist Movement in Peru
(2020-09-16)
In Latin America, rural and indigenous women have mobilised in defence of their territories and built strategic alliances with urban and mestiza feminist movements. This paper focuses on how these processes have played out in Peru, tracing the development of the discourse on ‘body as territory’, which articulates sexual and reproductive rights with territorial autonomy. It discusses the ‘cosmopolitics’ of translating the distinct concerns and worldviews of the women involved, arguing that this discourse has enabled ...

Developing Preliminary Scales for Assessing the HiTOP Detachment Spectrum
(2021-06-06)
The Hierarchical Taxonomy of Psychopathology (HiTOP) is an empirical-based classification of psychopathology. Detachment is one of the six spectra in the current HiTOP working model. The aim of this study was to develop preliminary scales for the HiTOP Detachment spectrum that can be used in the next phase of developing a comprehensive measure of HiTOP. We had 456 participants from MTurk (Sample 1) and 266 university students (Sample 2) complete an online survey including a pool of 247 Detachment items assessing 15 ...

Bygones in a public project
(2021-03-10)
The experimental literature suggests that contributions to a public good made dynamically, over multiple stages are higher than contributions made in a static setting, even when players do not receive feedback about co-players’ previous contributions between stages. Because the dynamic setting without feedback is strategically equivalent to the static one, this finding is puzzling. One important difference between the two settings, however, is that the dynamic setting gives the opportunity to sink contributions while ...

On the Expressive Power of Stateless Ordered Restart-Delete Automata
(2021-03-13)
Stateless ordered restart-delete automata (stl-ORD-automata) are studied. These are obtained from the stateless ordered restarting automata (stl-ORWW-automata) by introducing an additional restart-delete operation, which, based on the surrounding context, deletes a single letter. While the stl-ORWW-automata accept the regular languages, we show that the swift stl-ORD-automata yield a characterization for the class of context-free languages. Here a stl-ORD-automaton is called swift if it can move its window to any ...

Importance of sources of variability, scales and experimental design: A case study about the effects of biochar and slurry application on soil properties in agricultural silty loam soils
(2021-04-17)
In designed experiments, different sources of variability and an adequate scale of measurement need to be considered, but not all approaches in common usage are equally valid. In order to elucidate the importance of sources of variability and choice of scale, we conducted an experiment where the effects of biochar and slurry applications on soil properties related to soil fertility were studied for different designs: (a) for a field-scale sampling design with either a model soil (without natural variability) as an ...
