Abstract
Purpose
The purpose of this paper is to develop an automatic disassembly navigation approach for human interactions in the virtual environment to achieve accurate and effective virtual assembly path planning (VAPP).
Design/methodology/approach
First, to avoid the error-prone human interactions, a constraint-based disassembly method is presented. Second, to automatically provide the next operable part(s), a disassembly navigation mechanism is adopted. Finally, the accurate assembly path planning can be obtained effectively and automatically by inversing the ordered accurate disassembly paths, which are obtained interactively in the virtual environment aided with the disassembly navigation matrix.
Findings
The applications present that our approach can effectively avoid the error-prone interactive results and generate accurate and effective VAPP.
Research limitations/implications
There are several works that could be conducted to make our approach more general in the future: to further study the basic disassembly direction deducing rules to make the process of determining disassembly direction totally automatic, to consider the hierarchy of the parts in virtual reality system and to consider the space for assembly/disassembly tools or operators.
Originality/value
The approach has the following characteristics: a new approach to avoid the error-prone human interactions for accurate assembly path planning obtaining, a new constraint deducing method for determining the disassembly semantics automatically or semi-automatically is put forward and a new method for automatically identifying operable parts in VAPP is set forward.

Abstract
Purpose
The study conceptualizes how firms’ strategic motives interact with the heterogeneity of host country institutional environments in determining the subsidiary ownership. The author hypothesizes and tests two interaction effects. The study found that firms with market-seeking motives are more affected by the heterogeneity of host country institutional environments, while firms with resource-seeking motives are less affected by the heterogeneity. The empirical findings are based on a sample of overseas subsidiaries reported in the annual reports of listed firms in China.
Design/methodology/approach
In this study, an empirical investigation was conducted using a sample of subsidiaries of listed firms in China. The data were compiled from 2012 annual reports of listed firms in China. The sample consists of 2,270 subsidiaries of these firms.
Findings
The study conceptualizes that firms with market-seeking motives and resource-seeking motives are influenced differently by the heterogeneity of host country institutional environments in determining their subsidiary ownership. We hypothesize two interaction effects. Firms with market-seeking motives are more subject to the heterogeneity of host country institutional environments in determining their FDI ownership level. In contrast, firms with resource-seeking motives are less subject to this heterogeneity. The findings largely supported the study’s hypotheses.
Originality/value
This study fills an important gap in the literature by incorporating the interaction between strategic motives and host country environments in the analysis of subsidiary ownership. The findings of the study suggest that firms with a market-seeking motive are more particular about the host country institutional environments. They will acquire a high level of ownership in host countries with attractive institutional environments. In contrast, firms with resource-seeking motive are less concerned with the host country institutional environments. Their decision on subsidiary ownership is less affected by the variance in host country institutional environments. This study adds to the stream of studies that have examined outward investments of firms from emerging economies, particularly the outward expansion of Chinese firms with different strategic motives.

Abstract
Purpose
This paper aims to describe the corrosion behavior and possibility of inhibition by corrosion inhibitor SA1-3 in acidizing solution (5 per cent hydrochloric acid [HCl] solution). The study aims to explain the mechanism of corrosion and inhibition of N80 steel in 5 per cent HCl solution to provide theoretical basis for expanding the range of application of N80 steel in acidification process.
Design/methodology/approach
This paper opted for a laboratory study using simulation of acidizing solution to do the experiments. The results of experiments including weight-loss method, electrochemical method and surface analysis were used to explain the mechanism of corrosion and inhibition so as to predict the dissolution progress of N80 steel in 5 per cent HCl solution with and without inhibitor SA1-3.
Findings
This paper provides theoretical insights about how to inhibit the corrosion behavior of N80 steel in 5 per cent HCl solution. It suggests that the corrosion inhibitor which can form a protective film on the steel surface should be used to expand the application of N80 steel in acidizing solution. The inhibitor SA1-3 is a kind of cathodic corrosion-controlling inhibitor which mainly inhibits cathode corrosion; it cannot change the corrosion mechanism of N80 steel.
Originality/value
This paper provides a theoretical basis for the corrosion behavior and inhibition mechanism of N80 steel in acidizing solution.

Abstract
Purpose
In modern integrated modular avionics (IMA), it plays an important role to guarantee safety and reliability of the system. The safety and reliability of communication scheduling plays a crucial role in this IMA platforms-based network system. To verify the safety and reliability of the communication scheduling in this network, sufficient and typical test data must be generated to input into the network, obtain and evaluate the corresponding output.
Design/methodology/approach
To generate communication scheduling data, this paper presents an iterative communication scheduling data generation algorithm for a configured network of IMA platforms. First, the algorithm generates all possible communication schedules for the first timestamp. Then, constraint is introduced to decrease the quantity of communication schedules to improve the efficiency. The communication schedules are gradually extended to the second timestamp until the final timestamp, i.e. length of communication scheduling sequence.
Findings
To verify the efficiency and feasibility of the algorithm, a model is built based on the architecture analysis and design language (AADL) by mapping the correlation time of generated communication scheduling data into task properties. Schedulability is analyzed by loading this model into AADL Inspector. The simulation result illustrates that the proposed algorithm is efficient and feasible.
Practical implications
The proposed method can provide data support for communication scheduling test for the network of IMA platforms.
Originality/value
A constraint-based iterative communication scheduling data generation algorithm is proposed for the network of IMA platforms automatically.

Abstract
Conventional theories of market entry assume choice availability. This investment assumption is subject to challenges in the power generation market of an emerging economy where the host government controls most key resources and market entry choices. With such constraints, entrants become heavily dependent on their host country partners. This study investigates how the resource dependency frameworks explain better in respect of some US power generation firms that manage to operate electricity facilities in China whereas some have to abort. Using cross‐case analysis, patterns emerged illustrate how two groups of entrants manage key resources differently.

This paper aims to analyze the corrosion and corrosion inhibition of N80 in 10 per cent HCl + 8 per cent fluoroboric acid (HBF4) solution for acidizing operation.
Abstract
Purpose
This paper aims to analyze the corrosion and corrosion inhibition of N80 in 10 per cent HCl + 8 per cent fluoroboric acid (HBF4) solution for acidizing operation.
Design/methodology/approach
The corrosion rate, kinetic parameters (Ea, A) and thermodynamic parameters (ΔH, ΔS) of N80 steel in fresh acid and spent acid, 10 per cent HCl + 8 per cent HBF4, 10 per cent HCl and 8 per cent HBF4 solutions were calculated through immersion tests. The corrosion and inhibition properties were studied through X-ray diffraction and electrochemical measurements. The corrosion morphology of the corrosion product was examined by scanning electron microscopy (SEM).
Findings
The results demonstrated that the spent acid was the main cause of acidification corrosion, and the HBF4 would cause serious corrosion to N80 steel. The results showed that the N80 steel was more seriously corroded in the spent acid than in fresh acid, and the hydrolysis of HBF4 accelerates the dissolution process of N80 steel anode to control the corrosion reaction. The results showed that the acidification will definitely cause serious corrosion to the oil tube; therefore, necessary anti-corrosion measures must be taken in the acidification process.
Originality/value
The results showed that acidizing the formation with 10 per cent HCl + 8 per cent HBF4 will definitely cause serious corrosion to the oil tube, especially when the spent acid flows back. Therefore, necessary anti-corrosion measures must be taken in the acidification process, especially in the spent acid flowback stage.

Abstract
Purpose
In the context of circular economy, tourism resources development and integrated marketing need to interact with multiple businesses, data processing with big data technology, and in the information age, the best means of integrated marketing is to integrate business through an information platform. The research purpose of this article is to improve the intelligence of the tourism platform by constructing an OR model, integrate information and improve the data processing effect in an all-round way through data mining.
Design/methodology/approach
This study builds the business interaction in the form of OR (operations research model) model and combines this model with the e-commerce platform to build an online travel consumption model based on the user's online operation mode.
Findings
With the development of the times and the upgrading of industries, tourism and other industries have provided new tourism resources and tourism methods for human beings by virtue of the beautiful environment, special experiences and colorful stories and related industries have been related to the tourism industry based on natural resources, customs and folklore and agricultural experiences. By identifying important nodes with high connectivity in the social network, the weighted centrality algorithm can mine the importance of interest tags.
Originality/value
In addition, this research builds a test platform for model performance analysis and integrates various factors. The results show that the model constructed in this study can further promote the development of tourism, improve the efficiency of tourism resources, provide marketing effects and meet the circular economy theory.

Abstract
Purpose
Recognizing the significant impact of guanxi (the Chinese network of reciprocal business relations) and its influence on everyday dealings in China is important for Western firms. Researchers argue that social capital has limits and is not a commodity that has a place in China aspiring to be a global business hub. Accordingly, the purpose of this paper is to deal with the question of whether guanxi still matters in the Chinese business arena, and if so, to what extent.
Design/methodology/approach
To illustrate the evolutional direction of the Chinese institutional system, the authors compare it to a similar system that went through the evolutionary cycle from a social to a rational institutional base of exchange and discuss what one can learn from the institutional evolution process of the global diamond industry and its implications for the current evolution of Chinese institutions. The authors compare two similar cultures/religions, Judaism and Confucianism.
Findings
This study found parallels between the evolution of the Israeli diamond industry, dominated by Orthodox Jews, from a social exchange mechanism to a transactional mechanism and the present ongoing rationalization of the Chinese economy, dominated by the Confucianism culture from a social to a transactional business mechanism.
Originality/value
Despite the vast efforts of researchers in the area of guanxi, there is very little published knowledge about its limitations and its usefulness in today's changing business environment. This paper contributes to the existing literature on the future aspects of guanxi from a unique perspective – the evolution of the Israeli diamond industry.

Abstract
Looks at consumer research in Greater China including Mainland China, Hong Kong and Taiwan. Maps out the contributions within this area and guides future research. Examines the state of the art over the 1979‐97 period, with particular emphasis on the topics that have been researched, the extent of the theory development in the field and the methodologies used in conducting research. Uses content analysis to review 75 relevant articles. Suggests that, while a considerable breadth of topics have been researched, there remains much to be done, there is further room for theoretical development in Chinese consumer behaviour studies; and the methodologies used need improvement and further refinement.

Abstract
Considers the issue that Chinese people are more confident than Americans when answering general knowledge questions. Suggests that this over‐confidence may be indicative of other biases, such as over‐confidence in the ability to retrieve information accurately from memory. Presents empirical results demonstrating that the Chinese subjects were not over‐confident in their estimate of retrieval accuracy. Suggests the accuracy‐confidence correlation for Chinese subjects was significantly higher than the correlation for Western subjects. Discusses implications for current theories of judgement research and consequences for marketing.
