Investigating the mediating role of information sharing strategy on agile supply chain

Abstract: Article history: Received October 25, 2019 Received in revised format November 26, 2019 Accepted December 28 2019 Available online December 29 2019 Supply chains need to redesign their existing strategies and must develop new strategies to effectively face the challenges posed by certain disruptions, both man-made and natural. This requires the supply chains to be highly flexible, visible, reliable and cost-effective leading to the achievement of Agile Supply Chain (ASC). In today’s competitive market, achieving agility in supply chain needs dynamic leadership, strategic vision, mutual cooperation from all members and effective utilization of information technology through customer focus. In spite of their initiatives to achieve ASC for improving their organizational performance, barring a few large companies, the medium and small size manufacturing companies have not yet been able to adopt and design supply chains which lead to ASC. This may be due to various challenges in the process of achieving agility. Also, the published literature in this area is very scanty. Therefore, to fill this gap, the purpose of this study is to determine the mediating role of Information Sharing Strategy (ISS) on Agile Supply Chain (ASC) practices for achieving Supply Chain Performance (SCP) in medium size manufacturing companies in UAE. An empirical survey of supply chain managers in UAE is conducted for this purpose. It is found that information sharing plays a major mediating role in ASC to achieve superior supply chain performance.

Blockchain technology-enabled supply chain systems and supply chain performance: a resource-based view

Abstract: Using the resource-based theoretical view of the firm, this paper aims to explore how firms’ efforts to integrate blockchain technology (BCT) into their supply chain systems and activities enable certain supply chain capabilities and, consequently, improve their supply chain performance.,Using an abductive research approach, a qualitative content analysis was conducted on 126 cases of firms attempting to implement a blockchain technology-enabled supply chain system (BCTeSCS). These firms spanning across multiple industries were identified using the Nexis Uni database.,Findings reveal that present BCTeSCS efforts are more-oriented toward improving operational-level capabilities (information sharing and coordination capabilities) than strategic-level capabilities (integration and collaboration capabilities). These operational and strategic-level capabilities alongside BCTeSCS deliver several supply chains performance outcomes such as quality compliance and improvement, process improvement, flexibility, reduced cost and reduced process time. However, outcomes may vary by industry type based on their uncertainties.,Given the nascent state of BCT, accessibility to primary data about ongoing BCTeSCS efforts is limited. The presented framework is based on 126 cases of secondary information. Within this constraint, the paper finds scope to future empirical research by proposing a resource-based framework of BCTeSCS and related propositions.,The results and discussion of this study serve as useful guidance for practitioners involved in BCTeSCS integrations.,The paper creates a BCTeSCS scenario for stakeholders to assume its potential socio-economic and socio-environmental pressures.,This paper is one of the initial attempts to examine BCTeSCS efforts across multiple industries, and thus, promises a broad future research scope.

Shifting trust in construction supply chains through blockchain technology

Abstract: Blockchain technology is booming in many industries. Its application in supply chain management is also gradually increasing. Supply chain management (SCM) has long been committed to reducing costs and increasing efficiency and is trying to optimise resources and reduce the sector's fragmentation. Trust has always been an important factor in managing supply chain relationships, and it also affects the efficiency of supply chain operations. To this end, this study aims to examine how trust is affected by the introduction of blockchain technology in construction supply chain management.,This study is based on semi-structured interviews and publicly available information from experts in blockchain and construction supply chain management. Through content analysis, the data are analysed thematically to explore how various types of trust, such as system-based, cognition-based and relation-based, are affected by blockchain technology.,Blockchain technology provides solutions for data tracking, contracting and transferring resources in supply chain management. These applications help enhance the various sources of trust in SCM and provide supply chain partners with protection mechanisms to avoid the risks and costs of opportunistic behaviour in collaboration, shifting trust from relational to system-based and cognition-based.,This study focuses only on inter-organisational rather than interpersonal trust and empirical data from experts whose knowledge and cognition could be subjective.,Leveraging the potential of digitalisation to manage trust requires that leaders and managers actively try to improve contractual arrangements, information sharing and being open to new innovative technologies like blockchain.,From a relational view of supply chain management, the extent to which blockchain technology can develop and spread depends on the readiness of the social capital to accept decentralised governance structures.,This study builds upon an original data set and discusses features and applications of blockchain technology, explores the sources and dimensions of trust in supply chain management and explains the impact of blockchain technology on trust.

Blockchain based secured information sharing protocol in supply chain management system with key distribution mechanism

Abstract: The concept of Supply Chain Management (SCM) is very imperative while moving sensitive products from one entity to the next entity until it reaches to the end-users to avoid damage(s) in the product. In the traditional supply chain management system, several serious problems such as tampering of products, delay, and fraud, etc. exist. It also lacks proper authentication among the participants, data management as well as the integrity of the data. The blockchain mechanism is capable of solving the above-mentioned issues due to its important features such as decentralization, transparency, trust-less environment, anonymity, and immutability. This paper describes how the blockchain mechanism combines with the traditional pharmaceutical supply chain system and to achieve a better SCM system, we present a blockchain-based scheme for information sharing securely in the pharmaceutical supply chain system with smart contracts and consensus mechanism. The proposed scheme also provides a mechanism to distribute required cryptographic keys to all the participants securely using the smart contract technique. Further, transaction and block validation protocols have been designed in our protocol. The security analysis ensures that our protocol is robust and also achieves reasonable performance in terms of computation and communication overheads.

Learning from the Dark Web: leveraging conversational agents in the era of hyper-privacy to enhance marketing

Abstract: The Web is a constantly evolving, complex system, with important implications for both marketers and consumers. In this paper, we contend that over the next five to ten years society will see a shift in the nature of the Web, as consumers, firms and regulators become increasingly concerned about privacy. In particular, we predict that, as a result of this privacy-focus, various information sharing and protection practices currently found on the Dark Web will be increasingly adapted in the overall Web, and in the process, firms will lose much of their ability to fuel a modern marketing machinery that relies on abundant, rich, and timely consumer data. In this type of controlled information-sharing environment, we foresee the emersion of two distinct types of consumers: (1) those generally willing to share their information with marketers (Buffs), and (2) those who generally deny access to their personal information (Ghosts). We argue that one way marketers can navigate this new environment is by effectively designing and deploying conversational agents (CAs), often referred to as “chatbots.” In particular, we propose that CAs may be used to understand and engage both types of consumers, while providing personalization, and serving both as a form of differentiation and as an important strategic asset for the firm—one capable of eliciting self-disclosure of otherwise private consumer information.

Blockchain-Enabled Information Sharing Within a Supply Chain: A Systematic Literature Review

Abstract: A supply chain consists of many stakeholders such as suppliers, carriers and customers. It is often complex due to the rapid development of economic globalization and the intense competition pressure in the market which resulted in information sharing within a supply chain to be fragmented. Blockchain technology can solve this problem by having only a “one trusted ledger” that could reshape the element of data trust. The goal of this paper is to identify and understand the impact of blockchain technology for information sharing within a supply chain. The decentralized nature of blockchain technology offers a high level of transparency and has gained the attention from various sectors to deploy this technology. A systematic literature review in the academic literature was conducted using different databases. Blockchain-enabled information sharing can add value to enhance collaborative work in different types of supply chains such as health and medical, construction and smart city. From our findings, one potential impact of deploying blockchain-enabled information sharing within a supply chain is that it ensures all members in the chain can obtain verified information which enhances collaborative partnerships. Through this in-depth research, we highlighted potential barriers that could impede the development of blockchain technology in supply chain such as the lack of understanding of blockchain technology in businesses and conflict of interests. Future work such as information hiding, in parallel with information sharing, could close the gap in deploying this technology within a supply chain. Understanding the nature of different supply chain is also important to better prepare the deployment of blockchain. We acknowledge that our approach in selecting literatures in our systematic review may exclude certain literatures. Nonetheless, we tried to include as many relevant literatures as possible, to develop a roadmap on the current situation of blockchain-enabled information sharing within a supply chain.

Determinants of News Sharing Behavior on Social Media

Abstract: Social media is relied upon as a single portal for entertainment, communication, and news. To understand determinants of new sharing, we empirically evaluate data from 188 Facebook users with PLS structural equation modelling. Results support the significant influence of information sharing and status seeking gratifications on news sharing, and that this significance varies across contexts. We find that status seeking gratification has a stronger effect on news sharing when news quality is more emphasized. In other words, sharing low-quality news can be damaging to an individual’s status and they try to avoid it. However, information sharing gratification has a stronger effect on news sharing for those individuals who rely more on credibility and may be employing more heuristic selection approaches. This work has opened up new opportunities for further research and it is hoped that this may contribute to improving the quality and experience of news sharing in social media.

Blockchain-Based Sharing and Tamper-Proof Framework of Big Data Networking

Abstract: With the development of information technology, big data has had a positive impact on the development of various industries. However, the continued growth of data has led to difficulties in data sharing. Blockchain, with its information sharing characteristics and decentralized management principles, is expected to become the new engine for building a future data sharing platform. Blockchain-based data sharing is useful for recording user transactions and sharing of multi-platform data. However, this technology not only has challenges in information storage, but also risks in third-party transactions. In this article, we propose a big data sharing and transaction framework based on blockchain. This framework uses the blockchain decentralization and openness idea to establish a big data transaction platform for multiple users. For the problem of distributed secure storage of big data in the blockchain, we propose a data-tamperproof mechanism that introduces a cryptographic algorithm to prevent transaction data from being tampered with during user storage. The purpose of this article is to ensure transaction security and data reliability when trading in the blockchain.

What motivates physicians to share free health information on online health platforms

Abstract: Online platforms enable physicians to share health and medical information with the public; however, little research has been conducted to explore why physicians share free health education information. Drawing on motivation theory, this study develops a theoretical model to explore the influences of material and professional motivation on free information sharing and the contingent roles of professional expertise and online expertise. The model is tested using a six-month panel data set of 61,326 physicians’ sharing experiences. The results indicate that in addition to material motivation, professional motivation also plays a primary role in inducing physicians to share free information. However, when a physician's professional and online expertise is at a high level, the effect of material motivation is weakened and professional motivation plays a more important role. This study contributes to the literature on knowledge sharing, online health behavior, and motivation theory, and provides implications for practice.

The Passway of Women Entrepreneurship: Starting from Social Capital with Open Innovation, through to Knowledge Sharing and Innovative Performance

Abstract: Customs and culture should create women’s independence to actualize themselves in an era of emerging social progress in order to lead to the domination of women in the development of creative businesses. This research examines the role of social capital and whether it becomes a supporting or hindering factor in developing the creative industry of women entrepreneurs by examining the role of information sharing and innovations. Employing purposive sampling, questionnaires were distributed to 200 women entrepreneurs, and data were analyzed by using Structural Equation Modeling(PLS–SEM)software with SmartPLS Version 3.0. Social capital has a positive influence on the business performance of women entrepreneurs in Bali, Indonesia. Thus, the beliefs and norms that exist in the social capital of the Balinese Hindu concept can filter the information obtained from various information in business, which will ultimately be utilized by women entrepreneurs to create various innovations to meet the market demand. However, opportunities for women entrepreneurs are very limited to capital due to lack of guarantees to get capital, and a lack of entrepreneurship skills in the technological era, market access, bureaucracy, and legalization. Further, managerial skills, access to information technology, as well as the perspective that the men must be superior in Balinese culture and customs, make business for women entrepreneurs limited.

TROVE: A Context-Awareness Trust Model for VANETs Using Reinforcement Learning

Abstract: Vehicular networks have become a visible reality enabling information sharing between vehicles to enhance driving safety and provide value-added services to drivers and passengers. However, false information might be injected into the network because of defective sensors, malicious vehicles, and so on. Therefore, an efficient mechanism to guarantee the reliability of information used by vehicles is of great importance in vehicular networks. To solve this problem, this article proposes a context-awareness trust management model to evaluate the trustworthiness of messages received by vehicles to ensure bogus information will not influence the driving decision-making process. In the proposed scheme, the trust evaluation result of an evaluation request is determined by available related information and the evaluation strategy in the current situation, which is unaffected by the presence of conflicting evidence and the trust level of entities in the network. Moreover, we design a reinforcement learning model that allows vehicles to adjust the evaluation strategy so as to maintain an accurate evaluation result in different driving scenarios. Extensive experiments were conducted in different driving scenarios to verify the effectiveness of the proposed model. The results show that our model is adaptive to different driving scenarios with negligible time overhead, regardless of the proportion of malicious nodes in the network. Furthermore, compared with three types of state-of-the-art trust models in different scenarios, our scheme can achieve a higher evaluation precision rate with no more computational and communication overhead in nonrandom road conditions.

Healthchain: A novel framework on privacy preservation of electronic health records using blockchain technology.

Abstract: The privacy of Electronic Health Records (EHRs) is facing a major hurdle with outsourcing private health data in the cloud as there exists danger of leaking health information to unauthorized parties. In fact, EHRs are stored on centralized databases that increases the security risk footprint and requires trust in a single authority which cannot effectively protect data from internal attacks. This research focuses on ensuring the patient privacy and data security while sharing the sensitive data across same or different organisations as well as healthcare providers in a distributed environment. This research develops a privacy-preserving framework viz Healthchain based on Blockchain technology that maintains security, privacy, scalability and integrity of the e-health data. The Blockchain is built on Hyperledger fabric, a permissioned distributed ledger solutions by using Hyperledger composer and stores EHRs by utilizing InterPlanetary File System (IPFS) to build this healthchain framework. Moreover, the data stored in the IPFS is encrypted by using a unique cryptographic public key encryption algorithm to create a robust blockchain solution for electronic health data. The objective of the research is to provide a foundation for developing security solutions against cyber-attacks by exploiting the inherent features of the blockchain, and thus contribute to the robustness of healthcare information sharing environments. Through the results, the proposed model shows that the healthcare records are not traceable to unauthorized access as the model stores only the encrypted hash of the records that proves effectiveness in terms of data security, enhanced data privacy, improved data scalability, interoperability and data integrity while sharing and accessing medical records among stakeholders across the healthchain network.

Blockchain-based multiple groups data sharing with anonymity and traceability

Abstract: Group data sharing enables information sharing between multiple parties for cooperative purposes. However, the existing schemes only consider scenarios in which all parties in the same organization want to share data. Achieving secure data sharing between users of different groups is also a relevant research issue. In this paper, we propose a blockchain-based data sharing scheme for multiple groups with anonymity and traceability. Owing to the consortium blockchain technique, any user in the system can easily verify the validity of the shared data without interacting with a third-party auditor. Additionally, the proposed scheme can not only enable data sharing between different groups with enhanced security anonymously but also achieve traceability and non-frameability.

Blockchain for supply chain quality management: challenges and opportunities in context of open manufacturing and industrial internet of things

Abstract: In global Supply Chain Quality Management (SCQM), there are methods to ensure continuity of supply, at appropriate prices while meeting quality standards. But they are limited by the large and fallible role of humans, especially in manufacturing and quality control. Open Manufacturing aims to establish an open network of manufacturers that enables product information sharing among others in the production chain. Realizing the goals of open manufacturing requires processing the large datasets inherent to the production chain partners. But it is difficult to comply with the trust and privacy requirements of the suppliers in a supply chain. This paper presents a comprehensive survey of blockchain and its current and potential use in the industrial context including Industrial Internet of Things (IIoT)-based sensor networks, and the impact of the blockchain technology in manufacturing related areas such as traceability. The focus of this paper is on a potential application of blockchain in SCQM with detailed analysis of its technical feasibility and the methods of transitioning between the current approaches to a blockchain-oriented platform. An innovative use of blockchain to store referral information is also discussed. The survey concludes that blockchain along with IIoT can improve SCQM in an Open Manufacturing model.
