Recently, Professor Xu Tian from the College of Economics and Management at China Agricultural University, in collaboration with Mosses Lufuke from the Department of Economics at the University of Dodoma in Tanzania, uncovered the underlying reasons through data analysis. The related article has been published in Frontiers of Agricultural Science and Engineering (DOI: 10.15302/J-FASE-2025645).
Many people still fall for new forms of network marketing, multi-level marketing (MLMs) and other organisations that, despite their products, strongly resemble pyramid schemes. However, Claudia Groß (Radboud University) and William Keep (College of New Jersey) discovered that scientific research is remarkably lenient in its assessment of this business model. This may be because much of the research in this area is funded by lobby organisations, the researchers write in a paper published today in the Journal of Marketing Management.
Ultrasonic testing is a promising non-destructive evaluation technique across various industries. In a novel breakthrough, researchers from Chung-Ang University have developed DiffectNet, an AI-based technology that facilitates the diffusion-enabled conditional target generation of internal defects in ultrasonic non-destructive testing. This approach significantly outperforms traditional methods, potentially revolutionizing real-time defect reconstruction and prediction in highly reliability-critical industries, including aerospace, power generation, semiconductor manufacturing, and civil infrastructure.
Abstract
Purpose – This paper studies the determinants for the desirability of the public-private partnership (PPP) mode in infrastructure development.
Design/methodology/approach – The author manually collects data on over 12,000 PPP projects in China, and regard the successful transition and abnormal termination as signals for the mode’s desirability and undesirability, respectively. Then, guided by relevant theories in the literature, the author investigates the impact of various project characteristics on the projects’ successful transition and abnormal termination.
Findings – First, execution-stage projects in industries where government support is indispensable, or where quality improvement is more important than cost reduction, face higher likelihood of abnormal termination. But such negative effects are mitigated if state-owned enterprises (SOEs) participate in the social party. Second, the structure of social party matters. The participation by private firms in the social party increases the termination likelihood, while the decentralization of the social party decreases it. Third, pre-execution projects with government payment or subsidies are more likely to enter into the execution stage.
Practical implications – Regulations on participation by SOEs in PPPs, such as policy [2023 No. 115] announced by State Council, should take industrial heterogeneity into consideration.
Originality/value – Using a large sample, the author empirically tests the seminal PPP-related theoriesin the literature. The author also uncovers some unique stylized facts about PPPs in China, especially the impact of SOE participation in the social party on PPP survival.
