Online social networks are increasingly important venues for businesses to promote their products and image. However, information propagation in online social networks is significantly more complicated compared to traditional transmission media such as newspaper, radio, and television. In this chapter, we will discuss research on modeling and forecasting diffusion of virally marketed content in social networks. Important aspects include the content and its presentation, the network topology, and transmission dynamics. Theoretical models, algorithms, and case studies of viral marketing will be explored.

This paper examines the impact of residents’ human capital investment inequality on the urban–rural income gap, using China’s provincial panel data from 1997 to 2013. The results show that, at the national level as well as at the regional level, residents’ overall human capital investment inequality has a positive significant impact on the urban–rural income gap. In addition, the impact of overall human capital investment inequality increased monotonically from the eastern region inward to the western region. In terms of the relative impact of each component of human capital investment inequality on the urban–rural income gap, migration investment inequality appears to have the greatest impact at the national level, whereas health investment inequality has the greatest impact on the urban–rural income gap in the eastern region, and education investment inequality exhibits the greatest impact in the central and western regions. We also investigate the impact of human capital investment inequality on the urban–rural income gap over different periods. The results show that residents’ overall human capital investment inequality had a positive impact on the urban–rural income gap in the period 1997–2008, but the impact rapidly shrunk in 2009–2013. Furthermore, the impact of residents’ health investment inequality on the urban–rural income gap shows a downward trend, and the impact of residents’ education investment inequality trended slightly upward from 1997 to 2008, and then rapidly shrunk in 2009–2013. Finally, the impact of residents’ migration investment inequality was only significant in 1997–2002.

This chapter explores the significance of blockchain technology in protecting data for intelligent applications across various industries. Blockchain is a distributed ledger that ensures the immutability and security of transactions. Given the increasing need for security measures in industries, understanding blockchain technology is crucial for preparing for its future applications.

This chapter aims to examine the use of blockchain technology across industries and presents a compilation of existing and upcoming blockchain technologies for intelligent applications. The methodology involves reviewing research to understand the security needs of different industries and providing an overview of methods used to enhance multi-institutional and multidisciplinary research in areas like the financial system, smart grid, and transportation system.

The findings highlight the benefits of blockchain networks in providing transparency, trust, and security for industries. The Responsible Sourcing Blockchain Network (RSBN) is an example that utilizes blockchain's decentralized ledger to track sustainable sourcing from mine to final product. This information can be shared with auditors, corporate governance organizations, and customers.

The practical implications of this chapter are significant, serving as a valuable resource for industries concerned with identity privacy, traceability, immutability, transparency, auditability, and security. Understanding and implementing blockchain technology can address the growing need for secure and intelligent applications, ensuring data protection and enhancing trust in various sectors.

With the rapid development of China’s urbanisation and market economy, municipal solid waste (MSW) generation is increasing dramatically. In response to the threat of environmental pollution and the potential value of converting waste into energy, both the government and the public are now paying more attention to MSW treatment and disposal methods. In 2014, 178.6 million tonnes of MSW was collected at a safe treatment rate of 84.8%. However, the treatment methods and the composition of MSW are influenced by the collection area, its gross domestic product, population, rainfall and living conditions. This chapter analysed the MSW composition properties of Lhasa, Tibet, compared with other cities, such as Beijing, Guangzhou and so forth. The research showed that the moisture content of MSW in Lhasa approaches 31%, which is much lower than the other cities mentioned previously. The proportion of paper and plastics (rubbers) collected was 25.67% and 19.1%, respectively. This was 1.00–3.17 times and 0.75–2.44 times more than those found in Beijing and Guangzhou, respectively. Non-combustibles can reach up to 22.5%, which was 4.03–9.11 times that of Beijing and Guangzhou, respectively. The net heating values could reach up to 6,616 kilojoule/kilogram. The food residue was only half the proportion found in other cities. Moreover, the disposal method applied in each city has also been studied and compared.

Purpose – The purpose of this study is to investigate whether a firm’s cost structure (specifically, its cost stickiness) is associated with environmental, social, and governance (ESG) sustainability factors of performance and disclosure.

Methodology/approach – This study uses MCSI Research KLD Stats (KLD) and Bloomberg databases for the 13-year period from 2003 to 2015 in constructing ESG performance and disclosure variables, respectively. The authors adopt the general cost stickiness models from Anderson, Banker, and Janakiraman (2003) and Banker, Basu, Byzalov, and Chen (2016) to perform the analysis.

Findings – The authors find that a firm’s level of cost stickiness is positively associated with certain sticky corporate social responsibility (CSR)/ESG activities (both overall and when separately classified as strengths or concerns) but not with other nonsticky CSR activities. The authors also show that the association between cost stickiness and ESG disclosure is incrementally stronger for firms with CSR activities classified as sticky. Furthermore, the authors provide evidence that ESG disclosure is greater when both cost stickiness and the degree of sticky CSR activities increase. The authors show that when cost stickiness is high and CSR activities are sticky, management has incentives to increase CSR/ESG sustainability disclosure to decrease information asymmetry.

Originality/value – The findings present new evidence to understand how management integrates cost management strategies with various dimensions of sustainability performance decisions and show that not all ESG activities are equally effective when it comes to cost stickiness. The authors also demonstrate that increased sustainability disclosure helps reduce information asymmetry incrementally more when both costs are sticky and CSR activities are sticky.

COVID-19 pandemic was a health crisis that plunged the world into economic turmoil due to its resultant national lockdowns across economies which brought business and market activities to a standstill. In order to adapt to ensuing restrictions owing to the pandemic, forge ahead in a new way of living, work and interactions with one another (new normal), digitizing business and market operations is considered a necessary option. Sukuk is an essential Islamic capital market product whose operations involve multiple parties/intermediaries alongside some technical financial, administrative and legal/shariah processes. On this note, this chapter aims to study and examine the need for digitizing and automating sukuk operations and related activities to pave way for innovation, development and better continuity of sukuk market. In conducting the study, a review of literature approach is employed where relevant works on sukuk and fintech were examined. Using content analysis, the chapter explored digitization of sukuk in the Islamic capital market via fintech and blockchain and associated benefits, including peculiar challenges therein. An interview was also conducted to better understand the Wethaq case study. The chapter reveals that digitizing sukuk issuance adds value to sukuk and remedies certain inadequacies associated with sukuk transactions; can increase transparency of underlying sukuk assets and cash flows and can reduce costs due to lesser number of intermediaries. Digitization is the future of sukuk issuance and will promote sukuk well through the COVID-19 crisis and beyond.

This paper attempts to resolve the conflicting results on sticky cost behavior in prior literature. Large sample studies find that selling, general, and administrative costs (SG&A) and cost of goods sold (CGS) are sticky, that is, costs are less likely to decrease when activity decreases than to increase when activity increases. In contrast, studies limited to one industry find little or no sticky cost behavior.

We investigate whether SG&A and CGS sticky cost behavior differ across/ four major industry groups (manufacturing, merchandising, financial, and services) characterized by different production, operational, and economic environments. In addition, we study whether sticky cost behavior arises for all changes in activity level (as measured by revenue changes) or for only large changes in activity level. Finally, we investigate whether determinants of sticky cost behavior vary across industries.

Our results suggest that costs in the manufacturing industry are the “stickiest,” while costs in the merchandising industry are the “least sticky,” with financial and service industries exhibiting some level of sticky cost behavior. Further, we find that sticky cost behavior is industry-specific, both in the magnitude of activity changes that give rise to sticky cost behavior and in the determinants that drive the behavior.

Our investigation of 20 distinct sub-industries within the “stickiest” manufacturing industry finds that while some sub-industry groupings show significant sticky behavior, most do not. This result may explain why, contrary to large sample studies, single industry studies find little or no sticky behavior in costs.

Our research is the first to try and reconcile the conflicting results on sticky cost behavior. Understanding the pervasiveness of stickiness is necessary to move research forward in this domain.

This study explores the influence of cultural heritage tourism perception on China's tourism image. It analyzes the role of the spiritual bond established between overseas Chinese youth and the motherland during their visit to the cultural heritage sites in China. This study constructs a theoretical model with 350 overseas Chinese youth as samples based on the identity theory, Stimulus-Organism-Response (S-O-R) theory, and Howard-Sheth model. The results show that cultural heritage tourism perception directly and positively promotes cultural identity among overseas Chinese youth. It is also indirectly and positively associated with their cultural identity through enhancing the tourism image. Cultural intelligence plays a positive moderating role between cultural heritage tourism perception and cultural identity. The results provide significant implications for developing cultural heritage tourism and cultural communication.
