Big data analytics (BDA) and machine learning (ML) can be used to identify the influencing factors of online service supply chains (OSSCs) and can help in the formulation of optimal pricing strategies. This paper analyzes the influencing factors of customer online shopping from the demand-side perspective and formulates optimal pricing strategies from the supply-side perspective.

This paper uses ML and the Stackelberg game approach to discuss OSSC management. ML's feature selection algorithm is used to identify the important influencing factors of 12,330 customers' online shopping intention data using four different classifiers. The Stackelberg game approach is used to analyze the pricing strategies of integrators and suppliers in OSSCs.

First, the feature selection algorithm can improve the efficiency of optimization in big data samples of OSSCs. Second, the level of visualization and the quality of information (page value) will affect the purchase behavior of customers. Finally, the relationship between the optimal pricing and the level of visualization is obtained through the Stackelberg game approach.

This paper reveals the phenomenon of “mystery customers,” and the results of this paper can provide insights and suggestions regarding the decision-making behavior of integrators and suppliers in OSSC management.

Considering customer behavior intention, this paper uses a data-driven method to explore the influencing factors and pricing strategies of OSSCs. The empirical results enrich the existing OSSC management research, proposing that the level of product visualization and information quality plays an important role in OSSCs.

Based on a personality-behavior-outcome framework, this study analyzes how entrepreneurs' dual narcissism (i.e. narcissistic admiration and rivalry) affects new venture growth (NVG) through learning from entrepreneurial failure (LFEF) and discusses the moderating effect of personal initiative on the relationship between dual narcissism and LFEF.

A total of 294 entrepreneurs from different cities and industries in China were selected as the research sample. The mediation effect was examined using the PROCESS macro, and the moderation effect was tested via hierarchical regression analysis.

This study found that narcissistic admiration positively affected NVG, while narcissistic rivalry had the opposite effect. LFEF mediated the relationships between narcissistic admiration/rivalry and NVG. In addition, the effects of narcissistic admiration and rivalry on LFEF were moderated by personal initiative.

The findings suggest that entrepreneurs with narcissistic rivalry should deliberately regulate their cognition of failure and strengthen their learning from failure. Moreover, entrepreneurship education mentors should emphasize cultivating and guiding entrepreneurs' personal initiative in the context of frustration education. In addition, venture capitalists can consider incorporating the personality traits (i.e. dual narcissism and personal initiative) of entrepreneurs into the investment decision-making index system.

This study advances the relationship between narcissism and performance through the perspective of dual narcissism and provides a learning theory perspective for analyzing the narcissism–performance relationship. Moreover, by exploring the moderating role of personal initiative, this study enriches the understanding of the conditional factor that affects the ability to learn from failure.

This study explores the influence of sharing achievement (i.e. sustainability, enjoyment, and economic benefits) obtained by participating in the sharing economy on social entrepreneurial intention (SEI), as well as the role of perceived social worth and social entrepreneurial self-efficacy (SESE).

This study used multiple regression analysis on a sample of 331 MBA students aged between 24 and 48 years.

The findings indicate that sharing achievement is positively related with SEI, and perceived social worth mediates the relationship between them. Moreover, SESE not only has a moderating effect on the relationship between perceived social worth and SEI but also positively moderates the overall mediation model.

Entrepreneurship educators could focus on improving students' SESE through courses and training. Whereas, policymakers and decision makers should actively promote the sharing economy model and regulate its management. Moreover, existing organizers of the sharing economy should improve participants' sharing achievement.

This study determines the relationship between sharing achievement and SEI and enriches the push/pull theory from the perspective of pull factors in the context of the sharing economy. Moreover, by exploring the mediating effect of perceived social worth and the moderating effect of SESE, the study provides understanding on the influence mechanisms of sharing achievements on SEI.

Management response to consumer comments has become a widely adopted marketing strategy to address the undesirable effects caused by negative remarks. Yet, when and what management response is more effective and under what circumstances remains under-researched. This study aims to fill this gap.

In three experiments using five different products, the authors manipulate psychological construal level (psychological distance: distant vs proximal) and management response (response of primary vs secondary features) and thereafter assess their bearings on consumer psychological and behavioral reaction toward products of two distinctive natures (hedonic vs utilitarian).

At a psychological distance, consumers show a preferable reaction to management response of primary over secondary features. In contrast, when the psychological distance is proximal, consumers react more positively to management response of secondary than primary features. In addition, these effects vary as a function of product nature, hedonic vs utilitarian.

The findings of this research bring a significant contribution to marketing communication literature and extend the construal level theory.

A better understanding of the relative effectiveness of distinct types of management response to negative consumer comments is essential for more targeted and effective marketing strategies.

Little research has documented the effects of distinct types of management response. How psychological distance might underpin these effects has not been explored. In addition, whether the interaction effect of management response and psychological distance varies with differences in product nature, namely, hedonic and utilitarian, remains unanswered until this research.

This paper aims to extend previously reported research on the Sisyphus Effect in consumers’ decision making to consumers classified as either maximizers or satisficers. The purpose of this study was to examine whether the Sisyphus Effect influences consumer behavior related to purchasing brand-extension products and explore factors that influence the Sisyphus Effect in brand extension.

A survey was administered to participants in three studies. A convenience sample consisting of 875 participants was asked to complete the questionnaires. The authors assessed whether the participants were maximizers or satisficers. In addition, the participants were given information on brand-extension products that differed in the level of involvement and price and were asked whether they would purchase them.

Using regression analysis, the authors found that consumers’ willingness to purchase extended products became weaker as maximization tendencies became stronger. In addition, purchase involvement was confirmed as a situational factor that can increase maximization tendencies even in individuals who do not maximize as a default strategy. Finally, for low-involvement extended products, the authors found that product price played a moderating role in the negatively correlated relationship between maximization tendency and willingness to purchase a product.

This study suggests avenues to increase the effectiveness of a brand-extension strategy and illustrates some tactics that are not likely to be successful.

This paper aims to investigate effect of porous polystyrene microspheres encapsulated inhibitor on the protection performance of epoxy resin coating.

Porous polystyrene (PS) microspheres were synthesized by soap-free emulsion polymerization. The morphology of microspheres was observed by scanning electron microscopy and transmission electron microscopy. Corrosion inhibitor benzotriazole was encapsulated into porous PS microspheres. The protection performance of epoxy resin coating with different contents of PS microspheres was tested by polarization curve.

The findings of electrochemical impedance spectroscopy and scanning vibrating electrode technique showed that addition of corrosion inhibitor to porous PS microspheres further improved the protection performance of the coatings.

Porous PS microspheres could be used as nanocontainer to encapsulate corrosion inhibitor.

Addition of porous PS microspheres with corrosion inhibitor improved the protection performance of the coatings.

The development of project managers and leadership has been highlighted as crucial for improving project success and performance, resulting in a rise of interest in project leadership research over the last two decades. While several qualitative reviews have been conducted, there have been limited quantitative and systematic reviews on project leadership. This study fills this gap by portraying the knowledge landscape and tracking the evolution of project leadership research from 1998 to 2022 through bibliometric approaches.

Based on 816 records, including 793 articles extracted and selected from the Web of Science database and specific journals, and 23 articles selected from three non-SCI/SSCI indexed journals, the authors used CiteSpace and bibliometrix R-package to depict visualizations of the trajectory of co-cited references, the landscape of co-occurred keywords and emerging trends in project leadership via reference co-citation analysis, keyword co-occurrence analysis and thematic mapping.

The bibliometric analyses enabled the authors to understand the conceptual aspects of project leadership and its theoretical background. Three stages of the intellectual bases were identified and tracked: the infancy phase (1998–2007), the growth phase (2008–2014) and the new development phase (2015–2022). The results of keyword co-occurrence analysis indicated that the research focus evolved from investigating traits and competences to examining the effects of traditional leadership behaviors, and then considering context-specific leadership. The findings of thematic mapping and theoretical interpretation illustrate the potential directions of the competence comparison, new and appropriate leadership, and the interaction between leadership and context.

This study advanced the field by providing a systematic review of project leadership, developing potential future directions for project leadership research and providing practical implications for career development and training.
