This paper aims to investigate the high-temperature mechanical properties of HS110S steel and its corrosion behaviors in harsh downhole environment.
Abstract
Purpose
This paper aims to investigate the high-temperature mechanical properties of HS110S steel and its corrosion behaviors in harsh downhole environment.
Design/methodology/approach
In this work, mechanical property measurements were carried out from 25°C to 350°C and the scanning electron microscopy was used to observe the fracture morphology. The weight-loss measurements and surface characterization were used to evaluate the corrosion resistance of HS110S steel in harsh downhole environment.
Findings
Results show that the yield strength and tensile strength of HS110S steel at 350 °C are 779 and 861 MPa, respectively. Compared with room temperature, the reduction rate values are both less than 20%. At the high-temperature corrosion environment (350 °C), the static and dynamic corrosion rates are 0.9668 and 1.9236 mm/a, respectively. The generated corrosion products are mainly composed of FeSx, FeCO3 and Fe3O4. Therefore, the HS110S steel applied under such conditions needs to take suitable protective measures.
Originality/value
In general, the HS110 steel has widely used in conventional development conditions (e.g. low H2S or high CO2 environments). However, to the best of the authors’ knowledge, no studies have reported on its application at more than 250°C. Therefore, this work can be a reference to the application of HS110S steel in high-temperature corrosion conditions.

Abstract
Purpose
The purpose of this study is to analyze the performance of indigenous innovation in developing countries in the era of trade liberalization. It analyzes indigenous innovation from research and development (R&D) investments to innovation output and its effect on economic growth.
Design/methodology/approach
The sample for this study includes 20 middle-income countries across five continents for the period between 1994 and 2018. The study employs the Crepon Duguet and Mairessec CDM model in a panel data setting to do a multistage analysis of the innovation process. A vector error correction model VECM is employed to test for Granger causality between the variables investigated.
Findings
The results show that imports and foreign direct investments (FDI) have generally have short-run and long-run causal effects on domestic R&D investments. In regions where imports and FDI do not have individual causal effects on innovation output, a joint increase in each of them and R&D have both short-run and long-run causal effects. Indigenous innovation is a significant contributor to economic growth when a country can produce and export novel products.
Research limitations/implications
The sample is only limited to developing economies, and due to the unavailability of data, only 20 countries were captured.
Practical implications
Imported products and FDI are critical to the innovation drive when such activities are targeted at enhancing indigenous innovation from R&D to the production of new products. Hence, policy formulation should encourage the absorption of foreign technologies that serve as inputs to indigenous innovation.
Originality/value
This paper focuses specifically on indigenous innovation and analyses the influence of foreign technologies in this effort. It tests the moderating roles of imports and FDI in the relationship between R&D and innovation output, concluding that both variables enhance the effect of R&D on innovation output.

Abstract
Purpose
By comparing and contrasting the two scenarios of power producers investing in renewable energy and electricity sellers investing in renewable energy, we explore the conditions under which profit growth and carbon emission reduction can be realized, and provide a theoretical basis for decision-making on renewable energy investment by electric power companies as well as for government policy formulation.
Design/methodology/approach
This paper constructs a game model of a grid supply chain consisting of a leader generator and a follower seller in the context of the C&T mechanism, considering two scenarios in which the generator and the seller invest in renewable energy. Conclusions are drawn by comparing and analyzing the equilibrium solutions in different scenarios.
Findings
The scenario where electricity sellers invest in renewable energy exhibits a higher investment volume compared to the scenario involving power generators. In scenarios where power producers invest in renewable energy, electricity sellers achieve lower profits than power generators, while scenarios with electricity seller' investments yield higher profits for them. Increasing the cost coefficient of renewable energy investment reduces investment volume, electricity prices and electricity demand, leading to decreased profits for electricity seller but increased profits for power generator. A rise in the preference coefficient for renewable energy results in increased profits for electricity seller but decreased profits for power generator.
Originality/value
Addressing a literature gap in the context of low carbon, this study examines the investment scenario of electricity sellers in low carbon technologies, complementing existing research focused on power generators and consumers. The findings enrich knowledge in low carbon investment. By analyzing the investment decisions of both power producers and electricity sellers, this study explores the practical implications of renewable energy investments on the decision-making and operational dynamics of power supply chain enterprises. It sheds light on their profitability and investment strategies.

Abstract
Purpose
The authors position security measures and payment culture as key determinants of perceived security (PS) and trust. The purpose of this paper is to empirically investigate how PS and trust affect users’ attitude toward mobile payment use and why mobile payment has developed differently in the USA and in China.
Design/methodology/approach
Empirical data were collected from a survey conducted both in China and in the USA. The whole sample consists of 186 Chinese and 196 Americans. Partial least squares analysis was conducted to test the proposed relationships and multigroup comparison analysis was performed to examine the differences in the coefficients of those relationships between Chinese and the US model.
Findings
The findings show that payment culture (measured by coverage of mobile payment context (CMPC) and uncertainty avoidance (UA)) and security measures (measured by security technology protection (STP), security rules and policies (SRP), and security responsibility commitment (SRC)) have significantly positive impacts on the PS and trust, except that the positive impact of security on trust is not supported. The impacts of CMPC and PS on trust in the USA are significantly smaller than those in China, whereas the impacts of security measures and UA on PS and trust do not show significant differences between the two countries.
Research limitations/implications
Respondents of this study are selected from young educated population, the major users of mobile payment in 2015. However, recently with the increasing penetration of mobile payment, major mobile payment users are not only limited to young educated population, and thus there may be new findings after extending the range of respondents’ age. Since the research subjects in this study are the mobile payment of China and the USA, the authors could also expect different findings when the research subjects are extended or changed to other countries because of different mobile payment cultures across countries.
Practical implications
Findings in this paper will help mobile payment service providers to know the determinants of their users’ behavior intention and to take measures to improve these determinants, and these findings can also provide mobile payment service providers with insights into the differences in mobile payment use between the two countries and suggestions of measures that they can take to increase users’ attitude toward mobile payment use. Furthermore, the findings of this paper also help these providers globalize efficiently by paying more attention to those antecedents.
Social implications
The findings in this paper show that there is no difference in the impacts of UA and security measures on PS and trust between China and the USA. However, the impacts of PS and CMPC on trust in China are significantly higher than those in the USA. This is because that globalization has made people from different countries hold similar UA, whereas the CMPC, a construct refers to the business environment of mobile payment, is still very different between China and the USA.
Originality/value
This study extends prior studies of attitude toward mobile payment use through proposing that security measures and payment culture are key determinants of PS and trust and examining the role of PS and trust on the attitude. Furthermore, the empirical findings will not only provide mobile payment service providers with important insights into the differences in mobile payment adoption between the two countries, but also help these providers globalize efficiently by paying more attention to those antecedents.

Abstract
Purpose
The purpose of this study is to prolong the service life of the Al–Si alloy cylinder and achieve the objective of energy saving and emission reduction by the composite treatments.
Design/methodology/approach
Chemical etching + laser texturing + filled MoS2 composite treatment was applied to the friction surface of aluminum–silicon (Al–Si) alloy cylinder. The friction coefficient and wear loss were measured to characterize the tribology property of cylinders.
Findings
The composite-treated Al–Si alloy cylinder had the lowest friction coefficient and weight loss. The friction coefficient and weight loss of the composite treatment were approximately 27.08% and 54.17% lower than those of the untreated sample, respectively. The laser micro-textures control the release of solid lubricant to the interface of friction pairs slowly, which prolongs the service life of cylinders.
Originality/value
The synergistic effect of the chemical etching + laser texturing + filled MoS2 modified the tribology properties of Al–Si alloy cylinder. The chemical etching raised the silicon particles to bear the load, and laser micro-textures control the release of solid lubricant to improve the lubrication property.

Abstract
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.

Abstract
Purpose
This paper aims to propose a novel method to predict and alleviate feature fatigue. Many products now are loaded with an extensive number of features. Adding more features to one product generally makes the product more attractive on the one hand but, on the other hand, may result in increasing difficulty to use the product. This phenomenon is called “feature fatigue”, which will lead to dissatisfaction and negative word-of-mouth (WOM). Feature fatigue will damage the brand’s long-term profit, and ultimately decrease the manufacturer’s customer equity. Thus, a problem of balancing the benefit of increasing “attractiveness” with the cost of decreasing “usability” exists.
Design/methodology/approach
A novel method based on the Bass model is proposed to predict and alleviate feature fatigue. Product capability, usability and WOM effects are integrated into the Bass model to predict the impacts of adding features on customer equity in product development, thus helping designers alleviate feature fatigue. A case study of mobile phone development based on survey data is presented to illustrate and validate the proposed method.
Findings
The results of the case study demonstrate that adding more features indeed increases initial sales; however, adding too many features ultimately decreases customer equity due to usability problems. There is an optimal feature combination a product should include to balance product capability with usability. The proposed method makes a trade-off between initial sales and long-term profits to maximize customer equity.
Originality/value
The proposed method can help designers predict the impacts of adding features on customer equity in the early stages of product development. It can provide decision supports for designers to decide what features should be added to maximize customer equity, thus alleviating feature fatigue.
