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.
Ultrasonic-assisted extraction was employed for highly efficient separation of aroma oil from raspberry seeds. A central composite design with two variables and five levels was employed and effects of process variables of sonication time and extraction temperature on oil recovery and quality were investigated. Optimal conditions predicted by response surface methodology were sonication time of 37 min and extraction temperature of 54°C. Specifically, ultrasonic-assisted extraction (UAE) was able to provide a higher content of beneficial unsaturated fatty acids, whereas conventional Soxhlet extraction (SE) resulted in a higher amount of saturated fatty acids. Moreover, raspberry seed oil contained abundant amounts of edible linoleic acid and linolenic acid, which suggest raspberry seeds could be valuable edible sources of natural γ-linolenic acid products. In comparison with SE, UAE exerted higher free radical scavenging capacities. In addition, UAE significantly blocked H2O2-induced intracellular reactive oxygen species (ROS) generation.
In this study, we investigated the interventional effect of resistant starch (RS) obtained from purple yam (Dioscorea alata L.) on regulating lipid metabolism and gut microbiota in hyperlipidemic hamsters.
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.
