Do you have confidence in how your rolling stock has been maintained? A blockchain-led knowledge-sharing platform for building trust between stakeholders

This study explores the potential of blockchain technology in enhancing trust among the stakeholders responsible for the maintenance of rolling stock. Although the technology has been widely successful in the financial sector, it is still novel in the maintenance field. Given the customized nature of maintenance processes, it is unclear if a suitable consensus protocol can be identified that can enhance trust among stakeholders. This problem is investigated through the lens of the Design Science Research Methodology. First, the theoretical background of blockchain technology and its role in enhancing trust are explained, followed by the analysis of a current case at a Railway company to test the proof of concept. A business network archive is developed for the maintenance management of the sliding step of the train door system. The archive encompasses the business logic and transactional data required to enhance trust among stakeholders in the quality of performed maintenance. The developed archive is deployed on Hyperledger Fabric and the effectiveness of the solution is evaluated through a survey. The results show that the developed business network, deployed on a customized Hyperledger Fabric consensus protocol, enhanced trust among the stakeholders involved.     

Maintaining Relationship Alternatives Electronically: Positive Relationship Maintenance in Back Burner Relationships

Back burners are desired prospective romantic/sexual partners that people communicate with to establish a future romantic or sexual relationship. We surveyed 658 college students about the extent to which they reported using various positive relationship maintenance strategies (positivity, openness, assurances) during communication with their most important back burner. Consistent with previous research, singles did not differ from those in committed romances in the number of back burners reported; however, singles and casual daters utilized the positive maintenance strategies to a greater extent than did those in committed relationships. Men reported using more assurances than did women, but the sexes did not differ on the other strategies utilized. Implications and limitations are discussed.     

Relational Maintenance and Social Support in the Aftermath of Sudden and Expected Death

Bereavement is a state of grieving after the loss of a loved one. Past research has suggested that bereavement is particularly challenging, both physically and emotionally, in the aftermath of unexpected death. Here, we examine bereavement in which death occurred suddenly, compared to a chronic condition where death was expected, in terms of perceived social support and relational maintenance with the deceased in the form of imagined interactions and social media interactions. Results indicated that individuals experiencing sudden death bereavement were more likely to engage in both postmortem relational maintenance techniques and perceived less social support than individuals in the expected death bereavement group. Results are discussed in terms of previous findings.
