Bioreduction is an efficient approach to remediate Cr(VI)-contaminated soil, but further strengthening methods are still urgently needed. Herein, humic acid (HA) combined with vermiculite (VE) embedded an efficient strain Bacillus sp. CRB-7 was first used to investigate its performance and...

Active and highly stable OER electrocatalyst for PEM-based water electrolysis are currently in high demand. Herein, we report a rutile iridium-titanium oxide solid solution (IrTiO x ) through a facile one-step annealing of a Ti-based metal-organic framework precursor. The composite exhibits...

Combining the company’s risk of financial fraud predicted by the machine learning method and unique Chinese data of board voting, this study investigates whether independent directors can identify the company’s risk of financial fraud. We find that independent directors are more likely to...

In the context of the complexity of the global labour market for seafarers, crew study of seafarers (CSS) provides a means to access, analyse and compare information on active seafarers world-wide. This paper outlines the methodological parameters of CSS. It is argued that CSS provides a...

Network model recently becomes a popular tool for studying complex systems. Detecting meaningful communities in complex networks, as an important task in network modeling and analysis, has attracted great interests in various research areas. This paper proposes a genetic algorithm with a special...

The problem of spanning trees is closely related to various interesting problems in the area of statistical physics, but determining the number of spanning trees in general networks is computationally intractable. In this paper, we perform a study on the enumeration of spanning trees in a...

Sustainable development requires the balancing of economic growth with environmental protection. Since the late 1970s, China's government has been exploring a new path to improve its economic efficiency and decrease resource consumption and environmental pollution. Remarkable progress has been...

In this paper we evaluate three projects with the participation of 40 supplier firms in several Chinese coastal provinces representing multi-stakeholder efforts to provide alternative channels through which workers can voice their concerns. The supplier firms took on these projects to reduce...
