This study aims to identify which types of information quality influence purchase intentions the most in live streaming commerce and to examine the role of network size in this context.

We propose a model to investigate the correlation among the quality of different information in live streaming commerce, consumer trust, network size and purchase intention. An empirical analysis of 505 questionnaires was conducted by constructing a structural equation model.

The empirical findings indicate that information quality can directly enhance purchase intention and exert an indirect influence through the mediating factors of trust in products and streamers. Perceived network size positively moderates the relationship between information quality and trust in products. Of the five types of information, the quality of bullet-screen comments information is most important to consumers.

This study represents the first systematic analysis of how the quality of multiple types of information in live streaming commerce influences consumer trust and purchase intention, integrated within a unified framework. It uniquely introduces network size as a moderating variable, offering both theoretical insights and practical guidance for balancing information quality with network size in live streaming commerce environments.

This paper aims to explore the underlying mechanisms and boundary conditions through which equipment manufacturing enterprises can capture market value from digital transformation, with a specific focus on the roles of knowledge search and knowledge recombination.

This study uses a double fixed-effects model to test the hypotheses, using a unique data set of “firm-year” observations from 739 publicly listed equipment manufacturing companies in China, spanning the period from 2018 to 2022.

Digital transformation drives market value creation in equipment manufacturing enterprises through both breakthrough knowledge recombination (BKR) and progressive knowledge recombination (PKR). In addition, the analysis of marginal conditions reveals that diversified knowledge search serves as a substitute for digital transformation in promoting BKR, while also positively moderating the relationship between digital transformation and PKR.

Grounded in the knowledge-based view theoretical framework, this study introduces the novel concepts of BKR and PKR and systematically examines how digital transformation impacts market value in equipment manufacturing enterprises.

Harmonic gears always work under different operating conditions and may usually break down due to lubrication failures, while its lubrication mechanism is still not clearly understood. This paper aims to present a lubrication model comprehensively considering the influence of contact geometry, lubrication properties and three-dimensional (3D) real surface roughness to analyze the lubrication performance under different conditions.

Based on the discrete convolution-fast Fourier transformation with duplicated padding and quasi-system numerical methods, the lubrication model for harmonic gears is developed, which is verified by comparing results with available lubrication data.

The effects of meshing process, working conditions and 3D roughness on the lubrication characteristics are discussed. From the calculated cases, the increase in rotational speed and decrease of applied torque may increase the film thickness, enhancing the lubrication performance of harmonic gears. It is also observed that proper surface roughness can be used for lubrication design.

The research results can provide theoretical guidance for improving lubrication performance and reducing friction/wear of the harmonic gear interfaces. This study can be promoted to various engineering scenarios of harmonic gears, such as industrial robots, space-driven agencies and precision measuring instruments.

The purpose of this paper is to establish quantitative properties for the general systemic yoyo model so that this model can be readily employed to study problems from various disciplines of knowledge, be they from natural science or social science.

Figurative analysis combined with calculus‐based methods is applied in this research, in order to achieve the goal that whatever is obtained theoretically, here can be practically used in various applications.

The paper introduces the concepts of gravitation, potential energy, and yoyo potentials for general spinning yoyos and look at the structure of yoyo fields with relevant quantitative representations developed for practical computation purposes. The paper shows how the spin field of a yoyo can be decomposed into eddy and meridian fields and why spinning yoyos have the tendency to line up in such a way that their axes of spin are parallel to each other and their like polarities face the same direction. When looking at yoyo flows and resistances, the Kirchhoff Junction and Loop Laws are generalized to the most general case of systemic yoyos. By considering the concept of yoyo fluxes, it is possible to rewrite the Gauss's law in the relevant most general language.

This work is the first of its kind to develop quantitative methods for studying various properties of systems on a unified footing: the general systemic yoyo model. As shown in this special issue, the results of this work have been and will continue to be applied to address many difficult problems that have been encountering scholars in the areas of modern science and humanities.

Strategy.

The case is suitable for upper level undergraduate business and MBA students.

FOTILE, one of the fam ily businesses in Zhejiang, Ch ina, has now become the leading brand in the Ch ina kitchen appliance industry and has successfully entered into the global market. It has gone from a traditional family business in the 1980s to a modern enterprise because of the successful transformation from the first generation (Father: Lixiang Mao) to the second generation (Son: Zhongqun Mao) and the blending of a family business with the modern enterprise system. They both have strong beliefs that family businesses have their own advantages, but they have different ways and strategies of running the business. The case describes the process of how the father and his son worked together designing the strategies to successfully grow FOTILE.

The case is a vehicle for exploring strategies to operate a family business, to successfully develop a sustainability model, to manage a growing company through its entrepreneurial stage, and to merge western business culture with Chinese Confucian culture. It should help students to: explore strategies of managing/leading a family business and transferring successfully the business from one generation to the next; understand the importance of marketing, focusing on overall strategy and sustainability; know how to identify market opportunities, exhibit start-up intent, perform start-up planning, mission development, and feasibility analysis, and acquiring initial resources; and appreciate the close link between culture and strategy.
