Empirical studies show that people tend to be overconfident about the precision of their knowledge, leading to miscalibration. Consistent with this, we found that on overage the decision makers of Swiss pension plans provide too narrow confidence intervals when asked to estimate the past return of various assets. Their confidence intervals are also systematically too narrow in their forecast of...

This short paper introduces a novel use of timeline-based planning as the core element of a dynamic training environment for crisis managers called PANDORA. A trainer is provided with a combination of planning and execution functions that allow him/her to maintain and adapt a “lesson plan” as the basis for the interaction between the trainer and a class of trainees. The training session is base...

The paper finds that manager age and education have strong yet complicated effects. University education enhances efficiency if the manager is running a large bank. Managing director changes are systematically followed by efficiency changes....

We study the security of popular password managers and their policies on automatically filling in Web passwords. We examine browser built-in password managers, mobile password managers, and 3rd party managers. We observe significant differences in autofill policies among password managers. Several autofill policies can lead to disastrous consequences where a remote network attacker can extract ...

We assemble two reference point based concepts of utility in our empirical study: the own status quo and social comparisons. We explore the relative relevance of these concepts for total compensation as well as for different parts of the compensation package of managers. Making use of a unique panel data set of managers of the German chemical sector, we find that social comparisons of compensat...

taDOM* protocols are designed to provide lock-based approach to handle multiple access to XML databases. The notion of taDOM+ protocol is formalized and generalized and a formal model of taDOM+ lock manager that is parameterized in the number of transactions and in the size of database is represented. An important class of safety properties of taDOM+ lock managers were proven to be checked by e...

IT SHOULD come as no surprise to most nurses that the best and most experienced clinical members of wards or unit teams do not necessarily make the most effective managers. Yet employers persist in appointing senior clinical staff into ward or unit managerial posts, or worse, encourage clinical staff to take up managerial posts and then burden them further by asking them to retain clinica! resp...
