With the continuous advancement of economy, issues resource scarcity and environmental damage are becoming increasingly severe. For example, in terms water resources, problems pollution ecological imbalance caused by industrial agricultural wastewater more serious. In order to reduce pollution, protect promote balance, risks, it is necessary strengthen environment management. This study uses Malmquist DEA model conduct a on green technology innovation efficiency (GTIE) 24 governance...

Purpose Drawing on social exchange theory and a cultural perspective, this study examines the relationship between workplace ostracism job engagement by focusing mediating role of felt obligation moderating collectivism. Design/methodology/approach A two-wave survey was conducted over four months in private service business China. The participants comprised 108 Chinese employees. Findings results indicate that has negative with through reduced sense obligation. Collectivism strengthens main...

As a scarce strategic resource, the efficient utilization of rare earth resources is crucial for ensuring national economic security and promoting sustainable development. AI, core engine Fourth Technological Revolution, provides favorable opportunity to drive green technological innovation. Green efficiency in innovation has not been adequately studied, relationship between era AI still unclear. Based on above research gap, this study employs slack-based measure model perform both static...

Although the need to belong, or desire for interpersonal attachments, is a basic human motivation, understanding of how and when it influences workplace ostracism notably limited. Based on belongingness theory, this study examines negative relationship between belong exposure by focusing mediating role organizational deviance moderating in-role performance. Data from 108 supervisor–subordinate dyads in China were collected at three time points. The results reveal that mediates ostracism....

Performance pressure acts as a double-edged sword for employees. Based on an approach/avoidance framework, we theorize that performance produces both positive and negative effects employees' in-role behaviors via approach motivation (i.e., self-objectification) avoidance workplace anxiety), work meaningfulness moderates reactions to pressure. We examine our hypotheses using data from sample of 345 employees in various organizations. The results show self-objectification provides motive...

Rolling bearings are pivotal components in industrial rotating equipment and the issue of fault will occur inevitably due to long-term abrasion. This study proposes a novel GA-BP neural network (GA-BPNN) algorithm improve accuracy diagnosis rolling bearings. The genetic (GA) is employed optimize structure, initial weight threshold BP network, which can ability reduce time training. At first, structure determined so that optimal parameters GA be given, then population encoded. second,...

To achieve the harmonious development of economic growth and environment, nations must pay more attention to wastewater treatment boost efficiency using green technology. This study applies Malmquist-DEA model assess technology innovation in 19 Chinese companies between 2017 2020. In addition, focus is placed on core with excellent performance, indicating how may improve their The results indicate that, first, overall effectiveness follows a rising then decreasing trend. 2020, companies’ was...

Abstract On the base of nature Shapely Value, construction Value in cooperative game is analyzed this paper, and it concluded that made up two parts, one part depends on individual itself, other state alliance. Then used to discuss enterprise alliance rent put forward, finally some interesting conclusions are presented paper.

In this paper, rotor field oriented control of an asynchronous motor system based on the feedforward decoupling method is studied. The relationship between vector configurations, voltage schemes discussed. experimental results show ideal performance system.

In real life, because of the limited rationality and lack information, it is difficult for experts to give accurate judgments. A grey number such a whose exactly value unknown but range within which lies known. Therefore from system theory provides an important useful tool help describe judgments experts. The typical numbers include continuous discrete numbers. this paper, conception intersection group decision set up decide weight Based on it, aggregation approach discussed find accordant...
