We investigated the possibility that stallion whinnies, known to encode caller size, also encoded information about caller arousal and fertility, and the reactions of mares in relation to type of voice. Voice acoustic features are correlated with arousal and reproduction success, the lower-pitched the stallion's voice, the slower his heart beat and the higher his fertility. Females from three s...

Solutions to optimization problems of convex type are typically characterized by saddle point conditions in which the primal vector is paired with a dual ‘multiplier’ vector. This paper investigates the behavior of such a primal-dual pair with respect to perturbations in parameters on which the problem depends. A necessary and sufficient condition in terms of certain matrices is developed for t...

While the traditional conceptualization of the effect of losses focuses on bias in the subjective weight of losses compared with respective gains, some accounts suggest more global task-related effects of losses. Based on a recent attentional theory, we predicted a positive after-effect of losses on choice switching in later tasks. In two experimental studies, we found increased choice switchin...

Abstract Executives are increasingly facing various challenges associated with digitalisation, especially the simultaneous handling of many topics, loads information flushing in via digital channels, rapid changes, and finding right balance between old new. Building on a growing body research suggesting systematising leadership skills, we conduct an online-survey executives to investigate conne...

Abstract The presence of Lipschitzian properties for solution mappings associated with nonlinear parametric optimization problems is desirable in the context of, e.g., stability analysis or bilevel optimization. An example such a property set-valued mappings, whose graph set system inequalities and equations, R-regularity. Based on so-called relaxed constant positive linear dependence constrain...

This study was aimed at investigating how the Sade indigenous communities in Lombok carried out their socio-cultural transformation (especially during Covid-19 pandemic). Specifically, this sought for evidence of balanced demands tourism industry while preserving local culture pandemic. Transformation theory employed to examine balance, involving an analysis dialectical process community which ...
