Social Loafing in the Refugee Crisis: Information about Existing Initiatives Decreases Willingness to Help
(2017-05-11)
In light of the European refugee situation, we investigate how information about others’ support influences individuals’ willingness to help. When individuals see information about other people supporting refugees, they may either be influenced by a descriptive norm, and act accordingly. Alternatively, they may perceive that others are already doing the job, and thus engage in social loafing. In an experiment (N = 132), we tested these competing predictions. Specifically, participants were exposed to a map of Germany ...

A New Identity for Generalized Hypergeometric Functions and Applications
(2019-01-18)
We establish a new identity for generalized hypergeometric functions and apply it for first- and second-kind Gauss summation formulas to obtain some new summation formulas. The presented identity indeed extends some results of the recent published paper (Some summation theorems for generalized hypergeometric functions, Axioms, 7 (2018), Article 38).

Generating Causal Relations in Scientific Texts: The Long-Term Advantages of Successful Generation
(2019-02-05)
A high level of text comprehension can be achieved by engaging learners in processes of organization and integration while reading a cohesive text. In the present study, we investigated the impact of an innovative generative technique on learning with scientific texts. The cohesion generation was implemented by means of explicit cohesion gaps. High school students (n = 199) were randomly assigned to either receive a fully cohesive scientific text (control condition) or a scientific text that required the selection ...

Influence of Surface Roughness on Pressure Drop in Two‐Phase Flow of Saturated Hydrocarbons
(2019-12-19)
Pressure drop of propane and propylene in gas‐liquid saturation state are investigated for copper and mild steel test tubes. The surface structure of both tubes is determined with the focus variation method, yielding a six times higher roughness for the steel tube, although both tubes are manufactured in the same manner. In both tubes single phase pressure drop validation measurements are carried out and compared to known correlations. For two‐phase investigations both fluids are investigated at the reduced saturation ...

Feeding practices of pre‐school children and associated factors in Kathmandu, Nepal
(2019-11-03)
Background
In developing countries such as Nepal, many children aged below 3 years do not grow at a sufficiently high rate and are vulnerable to micronutrient deficiencies (e.g. vitamin A). Challenges to child nutrition can result from poverty, unhealthy traditional practices, inadequate caring and feeding practices. The present study aimed to assess the feeding practices of pre‐school children and their associated factors.
Methods
A cross‐sectional study was carried out in pre‐schools located in Kathmandu district ...

Bioeconomy from experts’ perspectives - Results of a global expert survey
(2019-05-01)
Effective global collaboration is crucial to achieving the UN Sustainable Development Goals (SDGs). It requires an understanding of the needs of individual countries and their expectations related to bioeconomy. With the aim to explore the prospective developments in the global bioeconomy over the next 20 years, the German Bioeconomy Council, an independent advisory body to the German Federal Government, commissioned BIOCOM-AG to invite experts from around the globe to share their insights in a global expert survey. ...

General Belief in a Just World Is Positively Associated with Dishonest Behavior
(2017-10-10)
According to the just-world theory, people need to – or rather want to – believe that they live in a just world where they will receive what they earn and consequently earn what they receive. In the present work, we examined the influence of people’s general and personal beliefs in a just world (BJW) on their (dis)honest behavior. Given that general BJW was found to be linked to antisocial tendencies, we expected stronger general BJW to be linked to more dishonesty. Given that personal BJW was found to be correlated ...

Candidates for photic entrainment pathways to the circadian clock via optic lobe neuropils in the Madeira cockroach
(2019-12-20)
The compound eye of cockroaches is obligatory for entrainment of the Madeira cockroach's circadian clock, but the cellular nature of its entrainment pathways is enigmatic. Employing multiple‐label immunocytochemistry, histochemistry, and backfills, we searched for photic entrainment pathways to the accessory medulla (AME), the circadian clock of the Madeira cockroach. We wanted to know whether photoreceptor terminals could directly contact pigment‐dispersing factor‐immunoreactive (PDF‐ir) circadian pacemaker neurons ...

IMF‐World Bank Cooperation Before and After the Global Financial Crisis
(2019-12-29)
This article adopts a diachronic view to compare patterns of institutional evolution of cooperation between the International Monetary Fund (IMF or Fund) and the World Bank (or Bank) before and after the global financial crisis. While the rules for Fund‐Bank cooperation had typically been tightened in response to crisis episodes, on balance they were loosened in the wake of the global financial crisis. Building on over 90 semi‐structured expert interviews and relevant official documentation, I argue that this new ...

Design of Robust Total Site Heat Recovery Loops via Monte Carlo Simulation
(2019-03-10)
For increased total site heat integration, the optimal sizing and robust operation of a heat recovery loop (HRL) are prerequisites for economic efficiency. However, sizing based on one representative time series, not considering the variability of process streams due to their discontinuous operation, often leads to oversizing. The sensitive evaluation of the performance of an HRL by Monte Carlo (MC) simulation requires sufficient historical data and performance models. Stochastic time series are generated by distribution ...
