This study aims to address the issues of limited pipe diameter adaptability and low inspection efficiency of current pipeline inspection robots, a new type of pipeline inspection robot capable of adapting to various pipe diameters was designed.

The diameter-changing mechanism uses a multilink elastic telescopic structure consisting of telescopic rods, connecting rods and wheel frames, driven by a single motor with a helical drive scheme. A geometric model of the position relationships of the hinge points was established based on the two extreme positions of the diameter-changing mechanism.

A pipeline inspection robot was designed using a simple linkage agency, which significantly reduced the weight of the robot and enhanced its adaptive pipe diameter ability. The analysis determined that the robot could accommodate pipe diameters ranging from 332 mm to 438 mm. A static equilibrium equation was established for the robot in the hovering state, and the minimum pressing force of the wheels against the pipe wall was determined to be 36.68 N. After experimental testing, the robots could successfully pass a height of 15 mm, demonstrating the good obstacle capacity of the robot.

This paper explores and proposes a new type of multilink elastic telescopic variable diameter pipeline inspection robot, which has the characteristics of strong adaptability and flexible operation, which makes it more competitive in the field of pipeline inspection robots and has great potential market value.

The robot is characterized by the innovative design of a multilink elastic telescopic structure and the use of a single motor to drive the wheel for spiral motion. On the basis of reducing the weight of the robot, it has good pipeline adaptability, climbing ability and obstacle-crossing ability.

This study uses data from the Chinese banking sector to explore the relationship between green credit and risk-taking in commercial banks. It also examines whether the level of regional green development acts as a moderator regarding this relationship.

Using a dataset composed of annual observations from 57 Chinese commercial banks between 2008 and 2021, this study employs both piecewise and curvilinear models.

Our results indicate that when the scale of green credit is low (<0.164), it increases the risk-taking of commercial banks. Conversely, when the scale of green credit is high (>0.164), it reduces the risk-taking of commercial banks. Moreover, this nonlinear relationship impact exhibits bank heterogeneity. Furthermore, the results show that the level of regional green development and local government policy support negatively moderate the relationship between green credit and commercial bank risk-taking. Furthermore, we find that green credit can directly enhance the net interest margin of commercial banks.

This study is the first to provide evidence of a nonlinear relationship between green credit and risk-taking in commercial banks, and it identifies the significant roles of regional green development level and local government policy support in the Chinese context.

With the wide adoption of information and communication technologies globally, digital marketing (DM) has emerged as an important and influential role in the growth and development of firms. However, it remains unclear how small and medium enterprises (SMEs) in emerging markets that normally have limited digital technology resources can gain benefits from DM. Thus, this research aims to investigate how DM benefits SMEs in emerging markets.

Drawing on the resource-based views (RBV) theory and a sample of 156,625 SMEs in Vietnam, this research uses statistical models and examines the performance of SMEs in terms of sales and productivity.

There is strong evidences that the sales and productivity performance of SMEs are positively affected by DM. Furthermore, there is evidence that corporate social responsibility plays an important role in moderating the influence of DM on SME performance.

This finding suggests that entrepreneurs should carefully consider using digital technologies to create DM strategies. This result also encourages local policymakers to invest more in digital technology and boost the growth of SMEs.

The purpose of this study is to investigate the pricing strategies for knowledge payment products, taking into account the quality level of pirated knowledge products, in the context of platform copyright supervision.

This study abstracts the knowledge payment transaction process and aims to maximize producer's revenue by constructing a pricing model for knowledge payment products. It discusses pricing strategies for knowledge payment products under two scenarios: traditional supervision and blockchain supervision. The analysis explores the impact of pirated knowledge products quality level and blockchain technology on pricing strategies and consumer surplus, while providing threshold conditions for effective strategies.

Deploying blockchain technology in platform operations can significantly reduce costs and increase efficiency. In both scenarios, knowledge producer needs to balance factors such as the quality of pirated knowledge products, the supervision level of platform, and consumer surplus to dynamically adjust pricing strategies in order to maximize his own revenue.

This study enriches the literature on the pricing models of knowledge payment products and has practical significance in guiding knowledge producer to develop effective pricing strategies under copyright supervision.

Hospitality and tourism businesses often face environmental criticism as they rely heavily on natural resources to operate. Therefore, as a recent trend, hospitality companies are trying to adopt an environmentally friendly approach. Thus, this study sought to investigate the determinants of employee intention to engage in environmentally responsible actions in the workplace, drawing on the theory of planned behavior (TPB) and the value-belief norm (VBN) theory.

This study employed the fuzzy-set qualitative comparative analysis (fsQCA) to discover sufficient configurations for predicting employees’ intentions.

The result has provided recipes with an efficient combination of factors that can influence employees’ intention to undertake environmentally responsible behaviors.

This study contributes to the body of knowledge regarding sustainable behavior among employees and sustainability in the travel and hospitality sector. The findings of this research also provide managers and operators of sustainable hospitality businesses with guidance on how to enhance their staff members' environmentally friendly behaviors at work.

This study aims to develop analytical models that consider product quality and production volume as essential drivers for profitability in the marketplace. It also considers product demand and price dynamics to understand related nuances backed by empirical validation.

The pricing mechanism is influenced by production quality, while product demand is influenced by both price and quality. The study considers cost elements, including production cost and quality loss cost which in turn are influenced by production volume and product quality. It establishes analytical conditions for optimal product quality and applies them to numerical analyses considering four distinct industry settings.

The study reveals that unique solutions exist for optimal product quality at each production level in four industry scenarios. The optimal production volume depends on product quality, and empirical research validates these findings from analytical models and numerical analysis.

This study represents a pioneering effort to investigate operational strategies in both analytical and empirical contexts, thus contributing to the existing body of knowledge in this area.

The purpose of current study aims to provide a different perspective on customer-based brand equity (CBBE) and integrate this with previous brand equity theory to contribute to the brand equity literature.

Proposed hypotheses were verified using structural equation modelling (SEM) with multiple datasets. Study 1 collected data from 574 foreign tourists and 624 domestic tourists of culinary tourism. Study 2 used 1,020 customers from anti-epidemic restaurants, and Study 3 investigated 464 hotel customers’ perceptions of customer-based brand equity.

Building on the mediation-moderation model, the present study posits that perceived quality relates to brand loyalty through brand image and brand awareness of using 2,682 participants. Specifically, we argue that this indirect relationship exhibits a difference moderated pattern in which motivation and hedonic function are most likely to benefit from revisit destinations for tourists when they are moderate. We further explored the new anti-epidemic concepts of COVID-19 and identified restaurant operation as an important moderator that influences customer image of restaurant revisit.

Until now, no tourism and hospitality studies have addressed these unsolved problems in an integrated manner. This study was to investigate the brand equity development process.

The purpose of this study is to examine how the childhood trauma experiences of CEOs influence firms’ internationalization.

The research used a difference-in-difference method with constructing a treatment group whose chief executive officer (CEO) experienced the great famine in China between the ages of 7 and 11, and a control group whose CEO was born within three years after 1961.

The study reveals a significant inverse correlation between CEOs’ childhood trauma experiences and firm internationalization. However, this correlation is weaker in the case of state-owned enterprises and firms led by CEOs with overseas work experience.

To the best of the authors’ knowledge, this study is the first to extend the theoretical framework to elucidate firms’ internationalization by introducing childhood trauma theory into the field of international business literature. Second, the authors link the literature on the effect of CEO explicit traits and psychological traits on firm internationalization by exploring how CEOs’ childhood trauma experience shapes their risk aversion, which, in turn, influences firm internationalization. Third, the authors address the call for examining the interplay of CEO life experiences by scrutinizing the moderating effect of CEO overseas work experience on the association between CEOs’ childhood trauma exposure and firm internationalization.

This study aims to investigate the effects of audit committees on the real earnings management (REM) in Islamic banks.

The sample data used in the study were retrieved manually from annual reports of 57 fully operational Islamic banks across 16 countries between 2012 and 2023.

The results indicate that the size of Audit Committee (AC), the presence of independent directors on the AC and AC diligence exert a significant and negative influence on REM in Islamic banks. In contrast, the proportion of directors with PhD and female directors in AC positively influences REM. However, the presence of foreign directors in AC does not impact REM in Islamic banks.

The study used six AC characteristics as part of the corporate governance mechanism to investigate their impact on REM in Islamic banks from 2012–2023.

The study contributes to the scanty literature showing how AC attributes influence REM in Islamic banks.
