Adaptation of supply management towards a hybrid culture: the case of a Japanese automaker

Purpose – This paper aims to identify problems caused by cultural differences between Japan and China that face supply chain managers by applying Japanese-style supply management practices within supply networks in China and present solutions to this problem. Design/methodology/approach – A single, longitudinal case study conducting two waves of data collection (i.e. interviews and observation) plus the collection of much archival data was performed. It goes beyond the dyad by examining supply management of a Japanese company’s supply chain up to three tiers in China. Findings – The four supply cultural differences between Japan and China, which caused the cultural clashes between JVCo and some of its suppliers were revealed and a model of adaptation of Japanese supply management to the Chinese business system was developed. Adaptation involves creating new supply management practices out of selective adaptation, innovation and change of existing Japanese and Chinese supply management practices rooted in different Japanese, Chinese and Western cultures. A list of organisational factors affecting the adaptation has also been provided. Research limitations/implications – Due to the adoption of a single case study method, caution should be given to generalising the findings to all Japanese firms. Practical implications – The Japanese, Chinese and Western managers were provided with insights on how to mitigate the problems caused by cultural differences within supply relationships in China and some innovative ideas on how managers from all three cultures could blend the elements of the three cultures to form a hybrid culture and reduce cultural clashes. Originality/value – This is one of the few attempts to study the transfer of Japanese supply management practice to China. Organizational theory (i.e. transfer of organizational practice and hybridization) is applied and provides a robust framework to explain the supply management practice. This study also answers the call for a global supplier relationship management paradigm

Biomechanical analysis of the Maxillary Sinus Floor Membrane During internal Sinus Floor Elevation With Implants at Different angles of the Maxillary Sinus angles

OBJECTIVE: This study analyzed and compared the biomechanical properties of maxillary sinus floor mucosa with implants at three different maxillary sinus angles during a modified internal sinus floor elevation procedure. METHODS: 3D reconstruction of the implant, maxillary sinus bone, and membrane were performed. The maxillary sinus model was set at three different angles. Two internal maxillary sinus elevation models were established, and finite element analysis was used to simulate the modified maxillary sinus elevation process. The implant was elevated to 10 mm at three maxillary sinus angles when the maxillary sinus floor membrane was separated by 0 and 4 mm. The stress of the maxillary sinus floor membrane was analyzed and compared. RESULTS: When the maxillary sinus floor membrane was separated by 0 mm and elevated to 10 mm, the peak stress values of the implant on the maxillary sinus floor membrane at three different angles were as follows: maxillary sinus I: 5.14-78.32 MPa; maxillary sinus II: 2.81-73.89 MPa; and maxillary sinus III: 2.82-51.87 MPa. When the maxillary sinus floor membrane was separated by 4 mm and elevated to 10 mm, the corresponding values were as follows: maxillary sinus I: 0.50-7.25 MPa; maxillary sinus II: 0.81-16.55 MPa; and maxillary sinus III: 0.49-22.74 MPa. CONCLUSION: The risk of sinus floor membrane rupture is greatly reduced after adequate dissection of the maxillary sinus floor membrane when performing modified internal sinus elevation in a narrow maxillary sinus. In a wide maxillary sinus, the risk of rupture or perforation of the wider maxillary sinus floor is reduced, regardless of whether traditional or modified internal sinus elevation is performed at the same height
