Abstract
Purpose
This paper aims to examine recent trends and China's role in the emerging global green system of innovation (GGSI) and present the major achievement in China's R&D sectors and major challenges faced by the country. The authors use China's role in the clean development mechanism (CDM) as a case to demonstrate the country's willingness to adopt new technology and green innovation.
Design/methodology/approach
In order to understand China's transformation towards the GGSI, the approach used in this study is a review of innovation systems literature combined with analysis of statistical data from various sources. The authors also build an innovation model for the emerging global green system of innovation to demonstrate the building blocks which allow for transformational system failures to be avoided. The clean development mechanism (CDM) is used as a case example as to how GGSI works.
Findings
This paper puts into perspective some recent developments in innovation and argues that there is enough evidence to claim that the world is re‐orienting towards a global green system of innovation in which China is already one of the most significant players.
Originality/value
Through building a new innovation model, this study demonstrates the complexity and the development of innovation in the context of China's transformation towards the GGSI.

Abstract
Purpose
The strength of ties between individuals influences the speed and spread of crisis information dissemination (CID). By constructing networks of strong and weak ties, this paper aims to innovatively explore the impacts of strong and weak ties on the CID at the macro level.
Design/methodology/approach
To better understand the rules of CID in different kinds of social networks, this paper constructs a CID model based on the strength of ties in social networks and cellular automation, using simulations of CID speed and spread in an entire network, strong tie network and weak tie network generated by MATLAB.
Findings
As the article's major theoretical contribution, the results demonstrate that CID is more efficient in a network of weak ties than in a network of strong ties, and that the spread of CID has a positive correlation with the believability of the information disseminated and the dissemination tendency coefficient. Furthermore, the difference of dissemination speeds between strong and weak tie networks varies regularly with information believability and the dissemination tendency coefficient.
Originality/value
This study provides more effective public mechanisms for rapidly evaluating the believability of crisis information and responding to crises in real time. The findings also have some valuable implications for government agencies to improve the efficiency and effect of CID.

Abstract
Purpose
Social media provides a convenient way to popularise first aid knowledge amongst the general public. So far, little is known about the factors influencing individuals’ adoption of first aid knowledge on social media. Drawing on the information adoption model (IAM), this study investigates the joint effects of cognitive factors (e.g. perceived information usefulness (PIU)), affective factors (e.g. arousal (AR)) and social factors (e.g. descriptive norms (DN)) on first aid knowledge adoption (KA) and examines their antecedent cues from the perspective of information characteristics.
Design/methodology/approach
The data were collected from 375 social media users, and the structural equation model was adopted to analyse the results.
Findings
The results indicate that PIU, AR and DN all have positive direct effects on first aid KA. Additionally, the study highlights the positive synergistic effect of AR and PIU. Furthermore, the study suggests that AR is determined by message vividness (MV) and emotional tone (ET), whilst DN are determined by peer endorsement (PEE) and expert endorsement (EXE).
Originality/value
Our research is groundbreaking as it delves into the adoption of first aid knowledge through social media, thus pushing the boundaries of existing information adoption literature. Additionally, our study enhances the IAM by incorporating emotional and social elements and provides valuable insights for promoting the spread of first aid knowledge via social media.

Abstract
Purpose
Multi-view fuzzy clustering algorithms are not widely used in image segmentation, and many of these algorithms are lacking in robustness. The purpose of this paper is to investigate a new algorithm that can segment the image better and retain as much detailed information about the image as possible when segmenting noisy images.
Design/methodology/approach
The authors present a novel multi-view fuzzy c-means (FCM) clustering algorithm that includes an automatic view-weight learning mechanism. Firstly, this algorithm introduces a view-weight factor that can automatically adjust the weight of different views, thereby allowing each view to obtain the best possible weight. Secondly, the algorithm incorporates a weighted fuzzy factor, which serves to obtain local spatial information and local grayscale information to preserve image details as much as possible. Finally, in order to weaken the effects of noise and outliers in image segmentation, this algorithm employs the kernel distance measure instead of the Euclidean distance.
Findings
The authors added different kinds of noise to images and conducted a large number of experimental tests. The results show that the proposed algorithm performs better and is more accurate than previous multi-view fuzzy clustering algorithms in solving the problem of noisy image segmentation.
Originality/value
Most of the existing multi-view clustering algorithms are for multi-view datasets, and the multi-view fuzzy clustering algorithms are unable to eliminate noise points and outliers when dealing with noisy images. The algorithm proposed in this paper has stronger noise immunity and can better preserve the details of the original image.

Abstract
Purpose
This paper aims to explore the influence of founder shareholders’ resources on the allocation of control rights from the perspective of incomplete contract theory and resource-based theory.
Design/methodology/approach
This paper analyzes newspaper materials with NVivo11on a case of battle for corporate control in Chinese top-listed company-Vanke Group.
Findings
The research shows that human capital is the key resource and the holding proportion of financial resources directly affects the allocation of control rights. At the same time, social capital is unstable and easily broken. At last, institutional environment also affects the degree between the relationship of founder shareholders’ resources and the allocation of control rights. The influence of founder-shareholder resources on the allocation of control rights follows the path of “crisis – founder-shareholder’s resources – founder’s ability - allocation of control rights.”
Research limitations/implications
This study only selects the financial capital, human capital and social capital of Shi Wang, the founder of Vanke, as the analysis object. The study can expand the types of founder shareholder resources to verify and enrich the conclusions.
Originality/value
The current theoretical research in the literature focuses on the necessity of equity and shareholder’s resources versus the control rights. Some key factors and mechanism on the relationship have not been fully clarified. The results of this paper not only extend the combination research of social network and corporate governance, but also provide enterprise founders with references for making reasonable decisions during control battle.
