Artificial intelligence for online characterization of ultrashort X-ray free-electron laser pulses
(2022-10-24)
X-ray free-electron lasers (XFELs) as the world’s brightest light sources provide ultrashort X-ray pulses with a duration typically in the order of femtoseconds. Recently, they have approached and entered the attosecond regime, which holds new promises for single-molecule imaging and studying nonlinear and ultrafast phenomena such as localized electron dynamics. The technological evolution of XFELs toward well-controllable light sources for precise metrology of ultrafast processes has been, however, hampered by the ...

Analytical perception and kinesthetic engagement in evaluation of copper chloride crystallization patterns of wheat, grape juice and rocket samples from conventional, organic and biodynamic cultivation
(2022-12-27)
Background:
When a dihydrate cupric chloride solution is crystallized in a petri dish in the presence of extracts of food products, dendritic crystal patterns emerge. The degree of growth, ripening and decomposition of the product is reflected in these patterns as salient unities (gestalts) of phenomenological features. In the present study we evaluated wheat, grape, and rocket (arugula) samples grown under different farming systems, fertilization treatments or horn silica application. The hypothesis of the present ...

Do Salient Social Norms Moderate Mortality Salience Effects? A (Challenging) Meta-Analysis of Terror Management Studies
(2022-08-11)
Terror management theory postulates that mortality salience (MS) increases the motivation to defend one’s cultural worldviews. How that motivation is expressed may depend on the social norm that is momentarily salient. Meta-analyses were conducted on studies that manipulated MS and social norm salience. Results based on 64 effect sizes for the hypothesized interaction between MS and norm salience revealed a small-to-medium effect of g = 0.34, 95% confidence interval [0.26, 0.41]. Bias-adjustment techniques suggested ...

Gamifying Online Training in Management Education to Support Emotional Engagement and Problem-solving Skills
(2022-09-28)
Online training to improve problem-solving skills has become increasingly important in management learning. In online environments, learners take a more active role which can lead to stressful situations and decreased motivation. Gamification can be applied to support learner motivation and emotionally boost engagement by using game-like elements in a non-game context. However, using gamification does not necessarily result in supporting positive learning outcomes. Our analysis sheds light on these aspects and evaluates ...

Stakeholder roles in sustainable supply chain management: a literature review
(2022-10-25)
Since ecological deterioration and social discrepancy are intensifying, multiple stakeholders are driving companies to incorporate sustainability in their supply chains. Thus, integrating non-traditional supply chain stakeholders, such as non-governmental organizations and competitors, in supply chain practices is essential for achieving a more sustainable supply chain. Hence, this research aims to show how stakeholders and their roles are related to sustainable supply chain management practices. A systematic literature ...

Valence sound symbolism across language families: a comparison between Japanese and German
(2022-12-13)
Vowels are associated with valence, so that words containing /i/ (as in English meet) compared with /o/ (as in French rose) are typically judged to match positively valenced persons and objects. As yet, valence sound symbolism has been mainly observed for Indo-European languages. The present research extends this to a comparison of Japanese-speaking and German-speaking participants. Participants invented pseudo-words as names for faces with different emotional expressions (happy vs. neutral vs. sad vs. angry). For ...

Effect of Thermo-Mechanically Activated Precipitation on the Hot Deformation Behavior of High Strength Aluminum Alloy AA7075
(2022-09-26)
The present study investigates the effect of two different microstructural conditions on the hot deformation behavior of precipitation-hardenable AA7075 by compression tests ranging from 200 °C to 350 °C and strain rates from 0.1 s-¹ to 10 s-¹. The first condition is solution heat-treated and quenched in water, whereas the second condition is achieved by subsequent artificial aging and stabilization for 24 h at the respective intended deformation temperature. Both conditions indicate an increase in flow stress with ...

Investigating Adsorption-Based Atmospheric Water Harvesting Potential for Pakistan
(2022-10-03)
Atmospheric water harvesting (AWH) can provide clean and safe drinking water in remote areas. The present study provides a comprehensive review of adsorption-based AWH by using the scientometric approach. The publication types are mainly composed of articles and reviews, accounting for 75.37% and 11.19% of the total, respectively. Among these publications, ~95.1% were published in English and came from 154 different journals which demonstrates that researchers have shown a great interest in this field. However, much ...

An insight into the runs of homozygosity distribution and breed differentiation in Mangalitsa pigs
(2022-10-18)
Mangalitsa pigs exhibit three distinct coat color patterns based on which they are described as Red, Blond, and Swallow-bellied. The current study investigated genome-wide diversity and selection signatures in the three breeds using fixation index, runs of homozygosity and population structure analyses. The analyses were originally based on quality-controlled data on 77 Mangalitsa animals from Germany, including 23 Blond, 30 Swallow-bellied and 24 Red Mangalitsa genotyped with a customized version of the ProcineSNP60 ...

Kann die Schule die Selbstwertentwicklung Jugendlicher positiv beeinflussen?
(2022-02-22)
Die drei Grundbedürfnisse Autonomie, Kompetenzwahrnehmung und soziale Eingebundenheit wurden wiederholt als mögliche Determinanten eines globalen Selbstwerts untersucht. Doch nur wenige dieser Untersuchungen erfassen explizit eine mehrjährige Selbstwertentwicklung und die Rolle der Schule bei der Erfüllung der Grundbedürfnisse während der Adoleszenz. In der vorliegenden Studie werden die Angaben von 334 Schüler*innen zur Gewährung von Autonomie durch die Lehrkräfte sowie deren Kompetenzrückmeldungen und die soziale ...
