Although innovative work behavior (IWB) is essential to organizational success and survival, little is known about its dispositional antecedents. In this study, we invoke regulatory mode theory to examine the independent and interactive effects of two regulatory orientations, assessment and locomotion, on three aspects of employee IWB: idea generation, promotion, and realization. Results from lagged survey data generally supported our hypotheses that each orientation would exhibit distinct effect patterns. For idea generation, assessment exhibited a positive relationship, whereas locomotion exhibited a negative relationship. Meanwhile, only locomotion was significantly (positively) related to idea promotion. And for idea realization, both assessment and locomotion exhibited positive associations. Furthermore, the interaction of assessment and locomotion in relation to each aspect of IWB also revealed distinct patterns: for idea generation, higher levels of assessment buffered against the negative effects of locomotion; for idea promotion, higher assessment constrained the positive effects of locomotion; and for idea realization, assessment supported locomotion, such that we observed greater realization levels when both regulatory modes were higher. We discuss the theoretical and practical implications of our results, as well as promising directions for future research concerning both regulatory mode and IWB. [ABSTRACT FROM AUTHOR]

Robust optimisation has been applied to the dispatching problem considering fault outage of power systems. The traditional fault outage uncertainty set are too conservative. To solve this problem, a robust contingency constrained unit commitment (CCUC) model considering the outage probability of units and transmission lines is proposed. The proposed model has the following characteristics: (i) the outage probability of units is determined by normal operation time and fault repair time, whereas the outage probability of transmission lines is determined by length and load rate; (ii) based on the probability criterion of unit outage contingencies, the outage probabilities of units and transmission lines are both incorporated into the modelling of uncertainty sets; (iii) the robust CCUC model obtains UC decision of base case and the UC decision under uncertainty scenarios can adjust the output of units by spinning reserve capacity to cope with stochastic fault outage scenarios. The proposed robust CCUC model is solved with Benders‐column and constraint generation (C&CG) method combined with Benders decomposition method and C&CG method. Simulations on the modified IEEE‐RTS‐79 system and IEEE‐RTS‐96 system demonstrate the effectiveness and reliability of the proposed robust CCUC model. [ABSTRACT FROM AUTHOR]
