Abstract

Background: With the rapid advancement of the technology industry, particularly in STEM fields, female professionals have increasingly become key drivers of innovation. Despite this, existing research has seldom examined the psychological impact of informal control on their innovation performance. Therefore, this study distributed questionnaires to female technology professionals in China's STEM field to investigate the effect of informal control on their innovation performance from a psychological perspective. It further explored the mediating role of role pressure and the moderating role of environmental turbulence in this relationship. Methods: This study primarily utilized AMOS 24.0 to develop structural equation models, and employed PROCESS 24.0 and SPSS 26.0 for data analysis purposes. Results: The findings reveal that informal control positively predicted the innovation performance of female technology professionals in STEM field. Role pressure partially mediates this relationship, while environmental turbulence positively moderates the relationship between informal control and innovation performance among female technology professionals in STEM field. Discussion: Theoretically, this research enriches the individual-level approaches to enhancing management control effectiveness. Practically, it aids managers in focusing on the psychological well-being of female technology professionals in STEM field, thereby facilitating the judicious selection of management control methods. The study's conclusions aim to provide logical guidance for enterprises to further strengthen their attention and support for female technology professionals in STEM field. Simultaneously, it offers a theoretical foundation for enhancing their innovative capabilities. [ABSTRACT FROM AUTHOR]

Abstract

Phosphogypsum (PG) contains a lot of soluble phosphate (PO43--P) and fluorine ion (F-), which seriously has hindered the sustainable development of the phosphorous chemical industry. In this study, a new burning raw material (BRM) as an intermediate product in the cement production process was used for PO43--P and F- stabilize in PG. The stabilizing mechanism of PO43--P and F- were investigated by Fourier Transform infrared spectroscopy (FT-IR), X-ray diffractometer (XRD), Scanning Electron Microscopy (SEM), X-ray fluorescence (XRF) and X-ray spectroscopy system (XPS). The effect of PG and BRM weight ratio, solid-to-liquid ratio, reaction time, and reaction temperature on the concentrations of PO43--P and F- were studied. The results showed that the concentration of F- in the PG leaching solution was 8.65 mg/L and the stabilizing efficiency of PO43--P was 99.78%, as well as the pH of the PG leaching solution was 8.12 when the weight ratio of PG and BRM was 100:2, and the solid to liquid ratio was 4:1, reacting for 24 h at the temperature of 30 ℃. PO43--P and F- were mostly solidified as Ca5(PO4)3F, CaPO3(OH), Ca5(PO4)3(OH), Ca2P2O7·2H2O, CaSO4PO3(OH)·4H2O, CaF2, and CaFPO3·2H2O. Leaching test results indicated that the concentrations of PO43--P, F- and heavy metals were less than the integrated wastewater discharge standard (GB8978–1996). This study provides a new harmless treatment method for PG.

35. Management control matching patterns and firm innovation modes.

Abstract

Using empirical data in China from 2010 to 2018, this paper investigates the relationship between management control matching patterns and different modes of innovation by introducing a text analysis method. The study found that adaptation matching pattern has a significant positive impact on radical innovation, execution matching pattern has a significant positive impact on incremental innovation, and compensatory matching has a significant positive effect on balanced innovation. Additional analyses further show that the positive 'control-innovation' relationship becomes more significant in high-tech firms. Environmental uncertainty and the degree of executive risk preference have a heterogeneous regulatory effect on the choice of control matching and innovation model. [ABSTRACT FROM AUTHOR]

42. Customer concentration and company risk‐taking: Effective contract or managerial power?

Author

Subjects

Abstract

This paper studies the relationship between customer concentration and company risk‐taking and its underlying application scopes. The results show that customer concentration is positively related to company risk‐taking. Additional analyses discuss the moderating effect of customer concentration on company risk‐taking from the perspectives of managers' characteristics and directors' characteristics. The view of effective contract is supported by all these results. This paper not only theoretically clarifies the underlying theoretical relationship between customer concentration and company risk‐taking but also provides empirical application situations for companies to design incentive contract and adjust risk‐taking level.

Abstract

Different algorithmic performances are required in different engineering fields for solving both the symmetric and asymmetric traveling salesman problem (STSP and ATSP), both of which are commonly referred to as TSP. In the background of small-scale TSP, according to the principle of the optimal Hamiltonian loop, this paper describes an angular bisector insertion algorithm (ABIA) that can solve TSP. The main processes of ABIA are as follows. First, the angular bisector of the point group is constructed. Second, the farthest vertex perpendicular to the angular bisector is identified as the search criterion. Finally, for both STSP and ATSP, initial loop formation rules and vertex insertion rules are constructed. Experiments were conducted for all STSP and ATSP instances with up to 100 points in the TSPLIB database. The performance of ABIA was compared with that of the 2-point farthest insertion algorithm, convex hull insertion algorithm, branch-and-bound algorithm, and a genetic algorithm. The experimental results show that, for small-scale TSP (up to 40 points), the runtime of ABIA is second only to the convex hull insertion algorithm, and the gap between ABIA and the optimal solution is second only to the exact algorithm. ABIA offers good overall performance in solving small-scale TSP.
