The assembly sequence in the product assembly process has effect on the final product quality. To solve the assembly sequence optimization problem, such as rotor blade assembly sequence optimization, this paper proposes a small world networks-based genetic algorithm (SWN_GA) to solve the assembly sequence optimization problem. The proposed approach SWN_GA consists of a combination between the standard Genetic Algorithm and the NW Small World Networks.
The selection operation and the crossover operation are improved in this paper. The selection operation remains the elite individuals that have greater fitness than average fitness and reselects the individuals that have smaller fitness than average fitness. The crossover operation combines the NW Small World Networks to select the crossover individuals and calculate the crossover probability.
In this paper, SWN_GA is used to optimize the assembly sequence of steam turbine rotor blades, and the SWN_GA was compared with standard GA and PSO algorithm in a simulation experiment. The simulation results show that SWN_GA cannot only find a better assembly sequence which have lower rotor imbalance, but also has a faster convergence rate.
Finally, an experiment about the assembly of a steam turbine rotor is conducted, and SWN_GA is applied to optimize the blades assembly sequence. The feasibility and effectiveness of SWN_GA are verified through the experimental result.

While in common English-language parlance speaking of “online celebrities” encourages the conflation of new forms of famousness with existing discourses on mass media stardom and fandom, the Mandarin Chinese term wanghong, a shorthand term for wangluo hongren (literally “person popular on the internet”), frames the enticing shores of online celebrity through the peculiar lexical domain of a grassroots popularity. The figure of the wanghong has in recent years accompanied the development of social media platforms in China, becoming a profitable profession, an inspirational role model, a morally condemnable by-product of internet economies, and in general a widely debated social phenomenon among local users. Drawing on interviews with more and less successful local online celebrities and discussions with their audiences, this chapter offers an up-to-date portrayal of the various forms of wanghong currently vying for attention on Chinese social media platforms, illustrating how popularity is crafted along with narratives of professionalism and economic aspirations intimately connected to the sociotechnical contexts of contemporary China.

This paper studies how a firm reacts to the threat from product market competition. Consistent with the strategic equilibrium model, we find that a firm increases investment in response to external product market threats. Further, the paper analyzes whether product market threats lead to an improvement in investment efficiency. When faced with product market competition, we find that firms that are otherwise likely to underinvest (overinvest) increase (increase) their investment significantly (less than the firms that are likely to underinvest) in the next period. However, firms that are predisposed to overinvest do not make cuts in capital expenditure, which indicates that strategic investment is a critical countermeasure for addressing competitive threats for all firms, their inclination to make suboptimal investment decisions notwithstanding. Overall, the evidence supports the predatory risk of waiting as well as competition and investment efficiency hypotheses. Additional tests suggest that product market threat partially substitutes for other external monitoring mechanisms designed to manage agency problems.

The purpose of this research is to deal with the human capital disclosure issue of present accounting systems. Many companies nowadays derive their competitive advantages mainly from human capital. However, under generally accepted accounting principles, all human‐related expenditures are treated as expenses, which are deductions of revenues, thus misleading decision‐makers into inappropriate judgments. This paper provides an alternative way of measurement and disclosure of human capital items in financial statements. The paper defines and classifies the human capital of a company in line with a theoretical framework provided by the authors, sorts out company's human capital investments according to cost development stages in human resources, isolates human capital from expenses and finally suggests disclosure in financial statements.
