As a universal workplace phenomenon, the impact of work-related rumination on job performance is attracting scholars’ attention. In the current study, the relationship between two types of work-related rumination, counterproductive behavior, and creativity at work were examined, as well as the mechanism of this association. Participants were 1109 employees from a variety of jobs in mainland China. The results showed that affective rumination was negatively associated with employees’ work creativity and positively associated with counterproductive behavior. On the contrary, problem-solving pondering was positively related to creativity and negatively related to counterproductive behavior. The loss of self-control resource partially mediated the link between affective rumination and counterproductive behavior. Problem-solving pondering had no significant impact on self-control resource. Results suggest the significant effects of problem-solving pondering may be positive in the workplace and clarify the self-control resource is the internal mechanism linking rumination and job performance.
This protocol describes an iodine/manganese catalytic system for dehydrogenative oxidative coupling reaction of indoles with thiols in anisole. Particularly, the dual roles of anisole have been first demonstrated as a solvent and as a promoter via the formation of an oxonium ion intermediate to accelerate the generation of products. A series of sulfenylindoles are readily constructed under aerobic mild reaction conditions. In addition, the achievement for preparing anticancer and anti‐AIDS drugs testifies the practicability of this approach. The mechanism studies disclose probable alternative pathways and a single‐electron transfer process are involved in this transformation.magnified image
In the data center networks, multipath transmission control protocol(MPTCP) uses multiple subflows to balance traffic over parallel paths and achieve high throughput. Despite much recent progress in improving MPTCP performance in data center, how to adjust the number of subflows according to network status has remained elusive. In this paper, we reveal theoretically and empirically that controlling the number of concurrent subflows is very important in reducing flow completion time (FCT) under network dynamic. We further propose a novel design called MPTCP_OPN, which adaptively adjusts the number of concurrent subflows according to the real-time network state and flexibly shifts traffic from congested paths to mitigate the high tail latency. Experimental results show that MPTCP_OPN effectively reduces the timeout probability caused by full window loss and flow completion time by up to 50% compared with MPTCP protocol.
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.
