The major purpose of this study is to investigate the role of coopetition among supply chains in blockchain adoption leading to sustainability in supply chains. This research uses a three-step process. First, a review of reviews is conducted to search the variables that would positively influence adoption of blockchain in supply chain. In the second step, total interpretive structural modeling (TISM) was utilized to understand the relationships among the enablers. Following the qualitative phase, an empirical study was conducted to test the hypotheses related to the mediating role of coopetition. Review of reviews identified 17 variables that can positively influence blockchain adoption in supply chain. The findings of TISM model revealed the hierarchical relationship among the enablers of blockchain adoption for supply chain management based on their relative importance. The results of the SEM-based study indicated that ‘coopetition’ plays a mediating role between the driver and dependent variables leading to sustainable supply chain. The research offers practical insights to integrate blockchain application in the supply chains leading to better supply chain transparency and ultimately sustainability. The research would support managers to develop suitable strategies to strengthen mechanism to enhance coopetition among competing supply chain to realize the benefits of emerging technologies. The originality of the study lies in the study of variables that influence blockchain adoption in supply chain using a mixed-method approach. Further, the research establishes the critical role of coopetition in achieving the benefits of blockchain adoption.

Purpose: Despite an exponential rise in the frequency of online payments in India, the cause of consumer resistance towards the WhatsApp payment system (WPS) remains unexplored. This research is aimed at exploring the barriers to the adoption of WPS.Design/methodology/approach: A research model was proposed using stimulus-organism-response framework and innovation resistance theory. Data were collected from 392 users of the WhatsApp application using the mall intercept technique, which also utilizes digital payment platforms. A co-variance based structural equation modelling was employed to test proposed relationships in this cross-sectional study.Findings: The study findings indicate that personal innovativeness as a personal stimulus negatively influences the usage and value barrier, while negative word of mouth (NWOM) increases the intensity of tradition and the image barrier. Additionally, value barrier, usage barrier, risk barrier and tradition barrier were found to have a negative influence on the intention to adopt the WhatsApp payment system.Originality/value: This research is an initial endeavour that sheds light on the consumer cognition resisting the adoption of the WPS.

Purpose: Effective leaders have emerged as the cornerstone of project success. The major purpose of this paper is to propose a framework to categorize and prioritize leadership competencies for project managers in megaprojects.Design/methodology/approach: In the first stage, this study utilizes PMBOK 6th Edition, IPMA ICB 4.0 frameworks to develop a hierarchy-based four clusters of leadership competencies. In the second stage, a Fuzzy-AHP (Analytic Hierarchy Process) approach was employed to prioritize the leadership competencies for an organization dealing in megaprojects. Finally, using ordinal priority approach (OPA), the results of Fuzzy-AHP method are validated.Findings: Based on PMBOK, IPMA and literature, the proposed framework deduced twenty-four leadership competencies and grouped them in four clusters. The Fuzzy-AHP results indicate that among clusters, people competencies cluster is ranked most important, followed by perspective, practice, and innovation competencies. Considering the sub-categories and global weights, culture/values, governance, interpersonal skills, and development and growth emerged as the most important leadership competencies. The results from OPA corroborate the findings of Fuzzy-AHP method.Practical implications: Megaprojects are characterized by massive investments and extensive economic and social impact. The proposed framework would be an important aid for policymakers to develop suitable strategies and programs to inculcate leadership competencies that would lead to successful project managers and improved project performance.Originality/value: The need for this research stems from the need to integrate popular project management frameworks in leadership competencies development in project based organizations. The proposed integrated framework, based on PMBOK 6th Edition and IPMA ICB 4.0 competency frameworks, is an original contribution to understand and prioritize leadership competencies for megaproject success.

Purpose: This study has two major objectives. First, comprehensively review the literature on transparency in supply chain management. Second, based on a critical analysis of literature, identify the attributes and sub-attributes of supply chain transparency and develop a numerical measure to quantify transparency in supply chains.Design/methodology/approach: A systematic literature review (SLR) was conducted using the PRISMA approach. Utilizing SCOPUS database past eighteen-year papers search resulted in 249 papers to understand major developments in the domain of supply chain transparency. Subsequently, graph theoretic approach is applied to quantify transparency in supply chain and the proposed index is evaluated for case supply chains from pharma and dairy sectors.Findings: It can be concluded from SLR that supply chain transparency research has evolved from merely tracking and tracing of the product towards sustainable development of the whole value chain. The research identifies four major attributes and their sub-attributes that influence transparency in supply chains, which are used to develop transparency index. The proposed index for two sectors helps to understand areas that need immediate attention to improve transparency in the case supply chains.Originality/value: This paper attempts to understand the development of transparency research in supply chain using the PRISMA approach for SLR. In addition, development of mathematical model to quantify supply chain transparency is a novel attempt that would help benchmark best practices in the industry. Further, transparency index would help to understand specific areas that need attention to improve transparency in supply chains.

In the age of globalization electronic marketing is a great revolution. Over the last decade majority of business organizations are running with technological change. Online shopping or marketing is the use of technology for better marketing performance. And retailers are devising strategies to meet the demand of online shoppers; they are busy in studying consumer behavior and attitudes in the field of online shopping. In our study, we also tried to study consumer's attitudes towards online as well as offline shopping and specifically studying the factors influencing consumers. This paper tries to understand the new behaviour which customers are now showing, showrooming and webrooming. The reasons for this new phenomenon and the reasons behind are analyzed and conclusions are made.
