To support vaccine decision-making, a growing number of parents use online communities to obtain informational and emotional support; however, relatively high information heterogeneity and polarization in the online environment make it challenging for parents to make informed vaccine decisions based on the systematic processing of conflicting information. In this context, this study aims to focus on the relationship between parents’ knowledge integration and rational and experiential decision-making and the mediating effect of anxiety on this relationship.

A theoretical model incorporating the direct and indirect effects of knowledge integration and anxiety on decision-making is proposed and tested through partial least squares structural equation modeling with survey data from 223 parents.

Knowledge integration negatively affects anxiety. Knowledge integration has a direct positive effect on rational decision-making and an indirect negative effect on experiential decision-making.

These insights into the key role of knowledge integration in parental vaccine decision-making under information heterogeneity and polarization provide support for practical strategies to encourage knowledge integration and alleviate anxiety in online communities.

This study underscores the importance of knowledge integration in vaccine decision-making under information heterogeneity and polarization and reveals distinct mechanisms underlying the effects of knowledge integration on decision-making dominated by rational and experiential modes. The findings also provide insights into the information processing mechanisms underlying the knowledge integration of subjects with insufficient prior knowledge in the non-organizational context.

The purpose of this paper is to demonstrate the effect of δ-ferrite on the susceptibility to hydrogen embrittlement of type 304 stainless steel in hydrogen gas environment.

The mechanical properties of as-received and solution-treated specimens were investigated by the test of tensile and fatigue crack growth (FCG) in 5 MPa argon and hydrogen.

The presence of δ-ferrite reduced the relative elongation and the relative reduction area (H₂/Ar) of 304 stainless steel, indicating that δ-ferrite increased the susceptibility of hydrogen embrittlement in 304 stainless steel. Moreover, δ-ferrite promoted the fatigue crack initiation and propagation at the interface between δ-ferrite and austenite. The FCG tests were used to investigate the effect of δ-ferrite on the FCG rate in hydrogen gas environment, and it was found that δ-ferrite accelerated the FCG rate, which was attributed to rapid diffusion and accumulation of hydrogen around the fatigue crack tip through δ-ferrite in high-pressure hydrogen gas environment.

The dependence of the susceptibility to hydrogen embrittlement on δ-ferrite was first investigated in type 304 steel in hydrogen environment with high pressures, which provided the basis for the design and development of a high strength, hydrogen embrittle-resistant austenitic stainless steel.

Social information is crucial to credit ratings and can improve the accuracy of the traditional credit assessment model. Drawing on the resource-based view (RBV) and social capital theory (SCT), this research explores the relationships between corporate social activities, network centrality and corporate credit behavior.

The authors used social network analysis (SNA) and regression analysis to analyze the data collected from 14,544 enterprises on the Alibaba platform.

The results indicate that among the four types of social activities, the number of corporate questions and posts shows a positive relationship with credit behavior; while the number of corporate comments has negative relationship with credit behavior. Further, degree and betweenness centralities mediate the relationship between the number of corporate questions, posts and comments with credit behavior.

This study contributes to the literature on non-financial factors (soft information) by exploring the social behavioral factors related to corporate credit. In addition, this study offers a new theoretical lens and reasonable explanations for investigating the relationship between corporate social activities, network centrality and credit behavior from the perspective of the resource-based view, while most studies are predictive and methodological. Moreover, this study provides new insights for platforms to evaluate enterprise credit and for managers to improve credit behavior.

This paper aims to determine to what extent hotels and peer-to-peer (P2P) facilities are substitutes for travelers. It then examines whether hotels target business travelers and P2P facilities target leisure travelers.

The author collected characteristics of Shanghai hotels and P2P facilities from websites to determine on what basis the two accommodation types compete. The author then conducted a modified importance-performance analysis (IPA) to determine the relationship between accommodations' provision of these characteristics and their importance to Chinese business and leisure travelers.

The characteristics of hotels and P2P facilities systematically differ, and travelers perceive these differences as important. While the differences are significant across all price ranges, they are smaller for budget hotels than for high-end hotels. The modified IPA indicates that P2P facilities appeal more to leisure travelers than to business travelers. Yet hotels better satisfy the requirements of both types of travelers.

The findings imply that P2P facilities can target lower- and middle-income vacationing families by charging lower prices. High-end hotels can compete by providing more diverse services and greater value to business travelers and higher-income leisure travelers. Budget hotels can reduce costs by not providing non-essential characteristics.

This paper contributes to the discussion of the competition between hotels and P2P facilities by focusing on the Shanghai market. It uses the modified IPA to derive implications for lodging market segmentation.
