Purpose This paper aims to investigate the way in which blockchain technology is likely to influence future supply chain practices and policies. Design/methodology/approach A systematic review of both academic and practitioner literature was conducted. Multiple accounts of blockchain adoption within industry were also consulted to gain further insight. Findings While blockchain technologies remain in their infancy, they are gaining momentum within supply chains, trust being the predominant factor driving their adoption. The value of such technologies for supply chain management lies in four areas: extended visibility and traceability, supply chain digitalisation and disintermediation, improved data security and smart contracts. Several challenges and gaps in understanding and opportunities for further research are identified by this research. How a blockchain-enabled supply chain should be configured has also been explored from a design perspective. Research limitations/implications This systematic review focuses on the diffusion of blockchain technology within supply chains, and great care was taken in selecting search terms. However, the authors acknowledge that their choice of terms may have excluded certain blockchain articles from this review. Practical implications This paper offers valuable insight for supply chain practitioners into how blockchain technology has the potential to disrupt existing supply chain provisions as well as a number of challenges to its successful diffusion. Social implications The paper debates the poential social and economic impact brought by blockchain. Originality/value This paper is one of the first studies to examine the current state of blockchain diffusion within supply chains. It lays a firm foundation for future research.

Purpose: This study was conducted to examine the longitudinal effects of parenting stress and parental control attitudes on problem behaviors in preschool children, using a latent growth model. Methods: Participants were 1,724 pairs of parents and 1,724 preschool children who had completed the panel survey on Korean children (5 th~7th survey panels). Results: An analysis of the multivariate latent growth model of parenting stress, parental control attitudes, and children's problem behaviors suggested that the parents' intercepts for parenting stress influenced their intercepts for parental control attitudes (father: b=.21, p<.001; mother: b=.55, p<.001). In addition, the slopes for fathers' parenting stress was the only aspect that affected the slopes for mothers' parental control attitudes (b=.77, p<.001). Moreover, both the intercepts and slopes of parenting stress and parental control attitudes significantly affected the children's problem behaviors. Conclusion: This study is significant as it provides longitudinal evidence of the impact of parenting stress and parental control attitudes on children's problem behaviors. The findings suggest that accurately assessing changes in parenting stress and parental control attitudes and developing intervention programs to reduce them will be effective in reducing problem behaviors in children.

Research relating to luxury brand resonance has typically focused on millennial consumers in developed countries. This has consequentially caused a lack of theory regarding how millennial consumers in developing countries build brand resonance with luxury brands. To fill this research gap, the current research examines millennial consumers' characteristics from developing countries. To test our model, we used structural equation modeling with 252 survey samples collected from China in 2019. This research identifies that the characteristics of millennial consumers in developing countries interact with the brand identification process to generate brand resonance. In doing so, this paper is able to identify the characteristics of developing countries millennial consumers. Secondly, this research also identifies that millennial consumers in developing countries are a unique cohort who have their own brand identification and assessment process. This study directs the way firms enable brand resonance for millennial consumers in developing countries.
