Rapid advances in information and communication technologies have promoted the evolution of digital governments and the digital transformation of firms (DTF). As a provider of public services and a regulator, the government is associated closely with the operations of firms. However, the manner by which a digital government contributes to the DTF remains unknown. In this study, we use a sample of Chinese A-share listed firms in 2021 to determine the configurations of digital government components that generate different levels of DTF via fuzzy set qualitative comparative analysis. Empirical results show that the synergy of multiple digital government components, instead of a single digital government component, generates high and non-high levels of DTF. Additionally, a digital government heterogeneously affects the digital transformation of state-owned and non-state-owned firms. Non-state-owned firms are more dependent on high-performing digital governments than state-owned firms in achieving high levels of DTF. These findings contribute to the understanding of the important role of digital governments and promote investigations into the driving mechanisms of the DTF. [ABSTRACT FROM AUTHOR]

A waterborne epoxy MIO intercoat with excellent anticorrosive performance is developed. The prepared intercoat is mainly used as inter-layer coating for steel structure anticorrosive coating system. The effects of different amine/epoxy mol ratio, the proportion of MIO in the filler, pigment volume concentration and the type and amount of rheological additives, etc. on the properties of coatings are investigated. The waterborne epoxy MIO intercoat prepared by optimized condition experiment has excellent acid and alkali resistance, heat and humidity resistance, low VOCs and small odor, meanwhile, it greatly reduces the health risks to constructor and meets the requirements of green coatings.

The desulphurization slurry flow of the coal-fired unit is usually regulated by a single PID loop that controls the pH value of the gypsum slurry. And the desulphurization system is characterized with large inertia and serious hysteresis, which often results in SO2 concentration of the outlet exceeding the standard, and leads the operators to turn the regulating valve to manual mode. The SO2 concentration of the outlet was taken into consideration into the optimized control strategy of desulphurization slurry supply introduced in this paper, and it is with the gypsum slurry pH value for cooperative control of the slurry regulating valve. Finally, the experiment proved that after the optimization of the control strategy, the desulfurization loop could be automatically put into operation for a long time, and the SO2 concentration of the outlet keeps stable, and the comprehensive utilization rate of limestone and the automation level of auxiliary equipment are significantly improved.

Massive open online courses (MOOCs) are very popular in China, and it is very important to evaluate and improve them. In this paper, a new evaluation method for MOOCs based on multi‐attribute group decision‐making is proposed. First, an evaluation index system of MOOCs is constructed, which contains six elements and 16 indicators, and multigranular unbalanced hesitant fuzzy linguistic term set (MGUHFLTS) is adopted to describe these indicators. Then based on MGUHFLTS, the aggregation operators are developed, including the multigranularity unbalanced hesitant fuzzy linguistic weighted averaging operator and the multigranularity unbalanced hesitant fuzzy linguistic order weighted averaging operator, moreover, a novel multi‐attributive border approximation area comparison model based on MGUHFLTS is proposed. This model is testified validity and superiority by comparison with other three methods and is applied in evaluation of MOOCs. After ranking five MOOCs, each indicator is analyzed to show how they influenced each element and suggestions are given. [ABSTRACT FROM AUTHOR]
