Abstract
Purpose
A large number of competitors springing up at the same time is a unique phenomenon to emerging markets. How to promote product sales and improve platform performance through appropriate advertising communication strategies is not only an actual problem for the P2P platforms that are committed to long-term and stable operations but also an academic problem in marketing.
Design/methodology/approach
This study collected a total of 1960 pieces of panel data of the P2P platforms and constructed a panel data analysis model after filtering.
Findings
The empirical analysis reveals the following: the prevention-focus advertising has a greater impact on platform trading volume, compared with the promotion-focus advertising, and the impact is positively significant; the platform which has a third-party cooperation should use promotion-focus advertising, while prevention-focus advertising is a better choice for the platform without a third-party cooperation. Furthermore, the effects of prevention-focus advertising and promotion-focus advertising on the platforms using individual projects and platforms using organization projects differ.
Originality/value
The results of this study have some reference to the selection of advertising communication strategies for the high-risk financial products.

Abstract
Purpose
Due to the special service environment of superalloys, this paper aims to obtain effects of temperature and Ti addition on high temperature oxidation behavior of Co-Al-W-B alloys.
Design/methodology/approach
Isothermal oxidation experiment of Co-Al-W-based alloys were carried out at 800°C, 900°C and 1000°C for different times (3, 5, 10, 20, 50 and 100 h) referring to the method of HB5258-2000. Oxidation weight gain curves and oxidation products were detected.
Findings
The results showed that the average oxidation rates of Co-Al-W-B alloy at 800 °C and 900 °C were 0.489 g·m−2·h−1 and 0.888 g·m−2·h−1, respectively, which belonged to an antioxidant grade. However, the average oxidation rate at 1000 °C was 2.068 g m−2·h−1, belonging to the secondary oxidation resistance class. In the alloy with Ti addition, dense Ti oxides film were formed at the early oxidation stage and then gradually diffused later, which can increase the oxidation resistance of the alloys to some extent. By analyzing the oxidation products of Co-Al-W-B alloy, it was found that a dense Al2O3 layer could be formed when the alloy was oxidized at 800°C. The continuous Al2O3 layer would prevent the oxygen from further spreading and make the alloy into the stable oxidation stage. However, only a non-dense Al2O3 layer were observed with 900°C oxidation.
Originality/value
It can provide references for the composition design, preparation process optimization and protective coating selection of the γ′ phase strengthened cobalt-base superalloys.

Abstract
Purpose
This study aims to investigate the influence of soy protein isolate hydrolysates (SPIH) obtained using 4 h hydrolysis under 200 MPa on proximate composition, cooking loss, textural properties, color, water distribution, microstructure, thiobarbituric acid reactive substance (TBARS) value and carbonyl and sulfhydryl contents of emulsion sausages.
Design/methodology/approach
Sausages with SPIHs at four concentrations (0, 1.0, 2.0 and 3.0%) were prepared, and the sausage with 0.01% butylated hydroxyanisole (BHA) was used as a positive control. Some sausages were selected for the analyses of quality characteristics and microcosmic properties. Other sausages were stored under 4 °C for 0, 7, 14, 21 and 28 days to investigate the oxidative stability.
Findings
The addition of SPIHs at various levels (0–3.0%) or 0.01% BHA did not affect the proximate composition (protein, fat and ash) of emulsion sausages. The addition of 2.0% SPIH decreased cooking loss and increased moisture content, hardness, springiness, chewiness, resilience and L* value, compared to the sausages without SPIH and with 0.01% BHA (p < 0.05). Furthermore, low-field nuclear magnetic resonance results suggested that sausages with 2.0% SPIH had the shortest T2 relaxation time. In addition, 2.0% SPIH and 0.01% BHA could inhibit the oxidation of emulsion sausages when compared with the sample without SPIH (p < 0.05). Moreover, there were no differences between sausages with 2.0% SPIH and 0.01% BHA (p > 0.05).
Originality/value
These findings confirmed that the 2.0% SPIH obtained under 200 MPa can be used as a natural additive to improve quality properties and antioxidant potential of emulsion sausages during storage.

Abstract
Corporate governance has attracted enormous attention both in the area of law and in the area of financial economics. In comparative corporate governance studies, many people have devoted their energy to find a best corporate governance model. I argue that a functional analysis does not support the view that there is a single best corporate governance model in the world. I further use the transplantation of an English style takeover law into China to show that the importation of foreign law is not always based on careful analysis whether the imported foreign law is the best in the world. Furthermore, I use the subsequent adjustment of the transplanted English takeover law in China to show that the imported foreign law is subject to local political and economic conditions. If there is no best corporate govern model and the transplantation of foreign law into other countries with different social and political background does not achieve similar objectives, the search for a best corporate governance model is misguided. Just as tort law or constitutional law regimes may have diversified models, so do corporate governance regimes in countries with different historical, social and political backgrounds.

This paper aims to investigate the relationship between the impact of COVID-19 on the performance of financial managers of medium and large companies.
Abstract
Purpose
This paper aims to investigate the relationship between the impact of COVID-19 on the performance of financial managers of medium and large companies.
Design/methodology/approach
This research used the data of 173 listed large and over-the-counter as medium-size companies from 2018 to 2021. The results of these tests have been analyzed using panel data and STATA 15 software.
Findings
The results showed that COVID-19 has no significant relationship with the return on equity in large and medium-size companies. This variable does not significantly affect Tobin’s Q index in medium-size companies either. Other financial indicators examined in this research have decreased considerably in all companies under the influence of COVID-19. Still, the intensity of this effect is different in large and medium-size companies. Funds from borrowings and Tobin’s Q ratios in medium-size companies compared with large companies have been more severely affected by the COVID-19 disease; the return on assets, book value to market value and large companies compared with medium-size companies have been more severely and significantly affected by COVID-19; and financing funds through the issuance of shares in large companies and medium-size companies have been affected by COVID-19 almost equally.
Originality/value
Despite the studies related to financial crises and their effect on the performance of companies, no research has examined the financial performance indicators during the outbreak of COVID-19 in large and small companies. Therefore, the results of this research can affect different groups: financial managers and the board of directors of companies to better understand the impact of the corona disease on the company’s performance; investors benefit from research results in line with investment decisions; developing theory and educational topics for the benefit of students and studying and conducting more experimental research in this regard; and the stock exchange organization and regulatory and support institutions need to find out the depth of the disaster and the effect of COVID-19 on the performance of companies.
