The purpose of this paper is to determine the failure reasons and failure mechanism of the commercially pure titanium air conditioning condenser.

In this paper, chemical analysis, metallographic observation, visual examination and scanning electron microscope examination, corrosion products analysis and working conditions analysis were adopted for determining the reasons for the failure of the condenser.

The results indicated that TA2 titanium pipe perforation failure is caused by the synergistic effect of crevice corrosion and deposit corrosion. The corrosion processes can be divided into three steps.

This research is an originality study on the failure case of a commercially pure titanium air conditioning condenser. This study makes up for the shortage of titanium alloy failure cases and also gives the result of the failure reason and failure mechanism for titanium, which has an engineering significance.

This case describes a real-time crisis experienced by the co-founder (Mr Yang) of a multi-national Chinese company operating in Vietnam during the 2014 Vietnam riot. After the strike broke out, Mr Yang made several critical decisions to protect and save both his factory and employees.

This case is applicable to graduate-level management courses such as: Business ethics, Decision-making, Business Communication and Cross-Cultural Management. Students should have some knowledge in Decision-Making concepts (e.g. “bounded rationality”); in Cross-Cultural Management concepts (e.g. “culture norms”); and in Strategic management theory such as “institution-based view” (e.g. formal vs informal institutions).

Part A of the case introduces the main character (Mr Yang) and his factory in Vietnam, the escalation of the strike and the course of the crisis. It also elaborates the important critical decisions Mr Yang made to save both his factory and employees. Part B of the case describes the rescue of Mr Yang and his Chinese employees, his actions after the crisis and strategic positioning in future business. Part C of the case introduces the aftermath of the riot and Mr Yang's reflection regarding the crisis.

The instructors may emphasize different learning objectives in different courses. Business Ethics: help the students learn to recognize, clarify, speak and act on their values when conflicts arise. Decision-Making: helps the students understand the logic of sense-making in crisis and the concept of bounded rationality. Business Communication: helps the students learn to raise issues in an effective manner and learn to deliver their own responses effectively. Cross-Cultural Management: helps the students identify and analyze the many ways in which managers can voice and implement their values in the face of critical moments in a different cultural environment.

The elderly service industry is emerging in China. The Chinese government introduced a series of policies to guide elderly service enterprises to improve their service quality. This study explores novel differentiated subsidy strategies that not only promote the improvement of service quality in elderly service enterprises but also alleviate the financial burden on the government.

Evolutionary game and Hotelling models are employed to investigate this issue. First, a Hotelling model that considers consumer word-of-mouth preferences is established. Subsequently, an evolutionary game model between local governments and enterprises is constructed, and the evolutionary stable strategies of both parties are analyzed. Finally, simulation experiments are conducted.

The findings indicate that local government decisions have a significant influence on the behavior of elderly service enterprises. Increasing the proportion of local governments opting for subsidy strategies helps incentivize elderly service enterprises to improve their service quality. Furthermore, providing differentiated subsidies based on the preferences of the customer base of elderly service enterprises can encourage service quality improvement while reducing government expenditure. The findings offer valuable insights into the design of government subsidy policies.

Compared with previous research, this study examines the role of consumer preferences in a differentiated subsidy policy. This enriches the authors’ understanding of the field by incorporating neglected aspects of consumer preferences in the context of the emerging elderly service industry.
