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 ...

Null and Void? Errors in Meta-analysis on Perceptual Disfluency and Recommendations to Improve Meta-analytical Reproducibility
(2021-02-03)
In the 2018 meta-analysis of Educational Psychology Review entitled “Null effects of perceptual disfluency on learning outcomes in a text-based educational context” by Xie, Zhou, and Liu, we identify some errors and inconsistencies in both the methodological approach and the reported results regarding coding and effect sizes. While from a technical point of view the meta-analysis aligns with current meta-analytical guidelines (e.g., PRISMA) and conforms to general meta-analytical requirements (e.g., considering ...

Summer aridity rather than management shapes fitness‐related functional traits of the threatened mountain plant Arnica montana
(2020-05-08)
Semi‐natural mountain grasslands are increasingly exposed to environmental stress under climate change. However, which are the environmental factors that limit plants in these grasslands? Also, is the present management effective against these changes? Fitness‐related functional traits may offer a way to detect changes in performance and provide new insights into their vulnerability to climate change. We investigated changes in performance and variability of functional traits of the mountain grassland target species ...

Augmented-Reality-basierte Assistenz für das Anlernen manueller und roboterunterstützter Montageprozesse
(2021-10-14)
Durch eine zunehmend flexibilisierte Produktion und relativ hohe Personalfluktuation bei einfachen Tätigkeiten wird das Anlernen neuer Mitarbeitender bzw. für neue oder geänderte Produktionsprozesse zunehmend relevanter. Konventionelle Anlernmethoden, bspw. durch Demonstration oder Arbeitspläne, haben Schwächen (bspw. binden sie zusätzliche Arbeitskraft oder sind kognitiv anspruchsvoll), die durch ein Augmented-Reality-(AR-)basiertes Assistenzsystem kompensiert werden können. Ein AR-Assistenzsystem zum Anlernen eines ...
