The aim of this study is to test the general hypothesis that parents and their children systematically differ with respect to the perception of their relationship as described by the literature on the ‘intergenerational stake’. To this end, the study compared 100 dyads of adult daughters and elderly mothers from Indonesia and Germany. Mothers and daughters were interviewed with respect to their...

BACKGROUND The aim of this study was to determine whether people respond differently to low and high stakes in Dictator and Ultimatum Games. We assumed that if we raised the stakes high enough, we would observe more self-orientated behavior because fairness would become too costly, in spite of a possible risk of a higher punishment. METHODS A questionnaire was completed by a sample of 524 uni...

This research explored how social distance affects risk preference in the life-saving domain. We found that decisionmakers tend to be more risk-seeking when the lives of close others versus distant others are at stake. By analyzing the shape of value function, we showed that the underlying mechanism for this difference in risk attitude might be that decision-makers engage in feeling-based evalu...

Decentralized cryptocurrencies have pushed deployments of distributed consensus to more stringent environments than ever before. Most existing protocols rely on proofs-of-work which require expensive computational puzzles to enforce, imprecisely speaking, “one vote per unit of computation”. The enormous amount of energy wasted by these protocols has been a topic of central debate, and well-know...

Exhaustive testing is never the appropriate approach in software testing as this violates the principle of cost effectiveness in software development as well as puts time and other resources at stake. This explains the need to optimise the process of software testing. The present paper gives an overview of cuckoo search algorithm and its role in software coverage optimisation. This paper propos...

The effects of stake size on cooperation and punishment are investigated using a public goods experiment. We find that an increase in stake size does neither significantly affect cooperation nor, interestingly, the level of punishment.
