This study aims to ensure the operation safety of high speed trains, it is necessary to carry out nondestructive monitoring of the tensile damage of the gearbox housing material in rail time, yet the traditional tests of mechanical property can hardly meet this requirement.

In this study the acoustic emission (AE) technology is applied in the tensile tests of the gearbox housing material of an high-speed rail (HSR) train, during which the acoustic signatures are acquired for parameter analysis. Afterward, the support vector machine (SVM) classifier is introduced to identify and classify the characteristic parameters extracted, on which basis the SVM is improved and the weighted support vector machine (WSVM) method is applied to effectively reduce the misidentification of the SVM classifier. Through the study of the law of relations between the characteristic values and the tensile life, a degradation model of the gearbox housing material amid tensile is built.

The results show that the growth rate of the logarithmic hit count of AE signals and that of logarithmic amplitude can well characterize the stage of the material tensile process, and the WSVM method can improve the classification accuracy of the imbalanced data to above 94%. The degradation model built can identify the damage occurred to the HSR gearbox housing material amid the tensile process and predict the service life remains.

The results of this study provide new concepts for the life prediction of tensile samples, and more further tests should be conducted to verify the conclusion of this research.

The purpose of this paper is to examine the impacts of companies’ voluntary adoption of the General Data Protection Regulation (GDPR) as well as the readability of privacy statements on US customers’ intention to disclose information and their trust in a company.

Building on the construal level theory and psychological distance, the authors conduct a 2 × 2 + 2 between-participants experiment with 255 participants.

The findings show that a company’s voluntary adoption of the GDPR has positive effects on customers’ intention to disclose information to and their trust in that company. In addition, the effects of GDPR adoption are stronger when the adopting company’s privacy statements possess a higher level of readability.

The authors believe this study poses policy implications for the outcomes of GDPR adoption and the recent debate on both a stricter data breach and privacy regulation.

This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies.

This briefing is prepared by an independent writer who adds their own impartial comments and places the articles in context.

Keystones are fundamental to the effectiveness of a business ecosystem. Appropriate sharing and utilization of resources is critical and keystones need to adopt relevant governance strategies and resource-focused actions to serve the needs of different ecosystem stakeholders in both resource sufficient and insufficient conditions.

This paper aims to review the latest management developments across the globe and pinpoint practical implications from cutting-edge research and case studies.

The National People’s Congress (NPC) of People’s Republic of China, the highest organ of state power, is popularly seen as a rubber-stamp entity. However, it has been substantially evolving its roles to accommodate the governance discourses within China’s political system over the decades. This study aims to explore the changes of governance discourse of the NPC within China’s political system through which to offer a thorough understanding of the NPC’s evolving substantial role in current China.

This study deploys a historical approach to explore the changes of governance discourse of the NPC that has seen a growing importance in China’s political agenda, as argued by this study.

The authors find that the NPC has been substantially evolving its role within China’s political system in which the Chinese Communist Party has created different governance discourses. Besides, the NPC and its Standing Committee have asserted its authority as a substantial actor within China’s political system. The NPC is no longer functioned as a rubber-stamp institution, though it is still popularized as a rubber stamp by many scholars.

This study is a historical elaboration on the development of NPC under three governance discourses. It might be, to some extent, relatively descriptive in nature.

This study, therefore, sheds some light on a revisit on the governance discourses in current China.

The purpose of this study is to broadly examine the role of marketing–finance interface factors for value creation. Specifically, the study investigates the influence of discretionary expenditures such as advertisement on valuation of brands and firms within the framework of risk factors.

To test the model and hypotheses of this study as it has the possibilities of multiple causations among different variables used in the system. Some independent variables are not truly independent and there is a possibility of biased estimation and inconsistent results. Hence a dynamic simultaneous equation model is used including the instrumental variable approach.

The study provides evidence for direct association between brand value and firm value which is represented by the joint impact of both operating and stock market performance. The results establish the direct relationship between brand and firm value and signify the relevance of intangible value creation.

This study addresses the gap in the research which examines the role of marketing decisions on value creation which jointly impacts both operating and stock market performance.
