BACKGROUND Because of reported associations of psychosocial factors and computer related musculoskeletal symptoms, we investigated the effects of a workplace psychosocial factor, reward, in the presence of over-commitment, on trapezius muscle activity and shoulder, head, neck, and torso postures during computer use. METHODS We measured 120 office workers across four groups (lowest/highest rew...

The thesis of this study is founded on the conviction that an organization cannot be expected to perform effectively and efficiently when its employees are not committed. There are many measurable support that employee commitment is a critical factor that d...

We consider robust pre-commitment and time-consistent mean-variance optimal asset allocation strategies, that are required to perform well also in a worst-case scenario regarding the development of the asset price. We show that worst-case scenarios for both strategies can be found by solving a specific equation each time step. In the unconstrained asset allocation case, the robust pre-commitmen...

Unconditionally secure quantum bit commitment has been shown to be impossible by Mayers [22] and Lo and Chau [18, 19], but the claim is repeatedly challenged. The bit commitment theorem is reviewed here and the central conceptual point, that an ”Einstein-PodolskyRosen’ attack or cheating strategy can always be applied, is clarified. The question of whether following such a cheating strategy can...

We report on experiments examining the value of commitment in Stackelberg games where the follower chooses whether to pay some cost to perfectly observe the leader’s action. Várdy [Games Econ. Behav. (2004)] shows that in the unique pure-strategy subgame perfect equilibrium of this game, the value of commitment is lost completely; however, there exists a mixed-strategy subgame perfect equilibri...

Human resources and knowledge management are considered to be one of the most important factors within organizations that help them to achieve a competitive advantage. However, organizations should take care of the human factor and increase their commitment within organizations to take advantage of the knowledge within them. The purpose of this research is to investigate the relationship betwee...
