PurposeThe purpose of this paper is to investigate how perceived supervisor support (PSS) affects employees' innovation implementation behavior (IIB), the psychological mechanisms of this relationship, and the role of perceived coworker support (PCS).Design/methodology/approachUsing a three-phase survey, data were collected from 307 employees of a state-owned coal company located in the central region of China. The study tests the hypotheses by using hierarchical regression analyses. The mediating effects and the moderated mediating effects are further examined by using bias-corrected bootstrapping methods.FindingsAffective commitment (AC) fully mediates the positive relationship between PSS and IIB, and this mediating effect can be moderated by PCS.Practical implicationsCompanies should foster supportive supervisors and colleagues by investing in appropriate training programs. In addition, managers should emphasize the psychological changes of employees and provide more supportive feelings for them.Originality/valueThe study explicitly tests the entire causal chain implied by organizational support theory in predicting IIB. It specifies the different role of two similar support constructs (i.e. supervisor support and coworker support) in affecting employees' attitudes and behaviors.
In this paper, we study the asymptotic equipartition property (AEP) for a nonhomogeneous Markov information source. We first give a limit theorem for the averages of the functions of two variables of this information source by using the convergence theorem for the martingale difference sequence. As corollaries, we get several limit theorems and a limit theorem of the relative entropy density, which hold for any nonhomogeneous Markov information source. Then, we get a class of strong laws of large numbers for nonhomogeneous Markov information sources. Finally, we prove the AEP for a class of nonhomogeneous Markov information sources.
In this paper, we study the strong law of large numbers and Shannon-McMillan (S-M) theorem for Markov chains indexed by an infinite tree with uniformly bounded degree. The results generalize the analogous results on a homogeneous tree. Keywords: Markov chains, Shannon-McMillan theorem, strong law of large numbers, uniformly bounded tree MSC(2000): 60F15, 60J10
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
