The classic Herlihy/Wing notion of concurrent objects has had great success in theories and implementations (e.g. java.util. concurrent), providing programmers with the simple abstraction of an atomic object. Since then, software transactions have appeared, also touting the the goal of providing an atomicity abstraction. However, despite some vertical composition strategies within particular ST...

Previous studies have demonstrated a relation between dispositional optimism and lower pain sensitivity, but the causal status of this link remains unclear. This study sought to test the causal status by experimentally inducing a temporary optimistic state by means of writing about and visualizing a future best possible self. In addition, we explored pain expectations and (situational) pain cat...

OBJECTIVES The relevance of the construct optimism in health psychology has been convincingly demonstrated in numerous studies. Population-based studies about dispositional optimism and the psychometric properties of the Life Orientation Test LOT-R as well as population-based norms are lacking. DESIGN A representative population survey in Germany was conducted to investigate psychometric prop...

Personal goals play a leading role in directing behavior and influencing well-being. Thus, it is important to assess goal dimensions promoting effective goal pursuit. The current research aimed at identifying the best predictors of goal pursuit, operationalized as perceived goal progress, among goal-related variables and individual differences in dispositional optimism. Two studies examined the...
