Abstract

Purpose

“Scale purification” – the process of eliminating items from multi-item scales – is widespread in empirical research, but studies that critically examine the implications of this process are scarce. The goals of this research are threefold: to discuss the methodological underpinning of scale purification, to critically analyze the current state of scale purification in supply chain management (SCM) research and to provide suggestions for advancing the scale-purification process.

Design/methodology/approach

A framework for making scale-purification decisions is developed and used to analyze and critically reflect on the application of scale purification in leading SCM journals.

Findings

This research highlights the need for rigorous scale-purification decisions based on both statistical and judgmental criteria. By applying the proposed framework to the SCM discipline, a lack of methodological rigor and coherence is identified when it comes to current purification practices in empirical SCM research. Suggestions for methodological improvements are provided.

Research limitations/implications

The framework and additional suggestions will help to advance the knowledge about scale purification.

Originality/value

This paper demonstrates that the justification for scale purification needs to be driven by reliability, validity and parsimony considerations, and that this justification needs to be based on both statistical and judgmental criteria.

Abstract

Purpose

Blockchain is increasingly being considered for applications in operations and supply chain management. However, evidence from practice is still scarce on why, where and how organizations seek to apply the technology in the supply chain across different industries. The study develops a comprehensive framework to enhance understanding of the application areas of blockchain technology in the supply chain, as well as organizations' motivations in seeking blockchain solutions and relevant contingency factors influencing applications.

Design/methodology/approach

The authors investigate 50 use cases of blockchain applications in the supply chain, covering six industries. Contingency theory is applied in conducting a qualitative textual and correlation analysis to identify and compare blockchain adoption motivations, application areas and contingency factors across different industries.

Findings

The analysis develops an evidence-based framework that captures ten principal motivations in seeking blockchain solutions, three main blockchain application areas along with important application sub-categories and five clusters of contingency factors that influence blockchain deployment and its uses in different industrial sectors.

Research limitations/implications

The study expands the limited cross-sectoral research on blockchain applications and motivations in the supply chain. Using contingency theory, it presents a comprehensive framework that captures the drivers and factors relating to blockchain adoption in the supply chain in a nomological network. The study lays the foundation for further theoretical perspectives and empirical research to investigate relevant sectoral characteristics and their importance for different types of blockchain application in the supply chain.

Practical implications

The study informs practitioners about potential supply chain application areas that can be enhanced through blockchain technology, taking account of the specific characteristics of their products, business and manufacturing processes, supply network configurations, industry standards, regulations and market demand.

Originality/value

The study is the first to provide cross-sectoral evidence on the relevance of organizations' motivations and numerous contingency factors on blockchain application areas in the supply chain.

Abstract

Purpose

Academics and practitioners have long acknowledged the potential of multiagent systems (MAS) to automate and autonomize decision-making in logistics and supply chain networks. Despite the manifold promises of MAS, industry adoption is lagging behind, and the exact benefits of these systems remain unclear. This study aims to fill this knowledge gap by analyzing 11 specific MAS use cases, highlighting their benefits, clarifying how they can help enhance logistics network resilience and identifying existing barriers.

Design/methodology/approach

A three-stage Delphi study was conducted with 18 industry experts. In the first round, these experts identified 11 use cases of MAS and their potential benefits, as well as any barriers that could hinder their adoption. In the second round, they assessed the identified use cases with regard to their potential to enhance logistics network resilience and improve organizational productivity. Furthermore, they estimated the complexity of MAS implementation. In the third round, the experts reassessed their evaluations in light of the evaluations of the other study participants.

Findings

This study proposes 11 specific MAS use cases and illustrates their potential for increasing logistics network resilience and enhancing organizational performance due to autonomous decision-making in informational processes. Furthermore, this study discusses important barriers for MAS, such as lack of standardization, insufficient technological maturity, soaring costs, complex change management and a lack of existing use cases. From a theoretical perspective, it is shown how MAS can contribute to resilience research in supply chain management.

Practical implications

The identification and assessment of diverse MAS use cases informs managers about the potential of this technology and the barriers that need to be overcome.

Originality/value

This study fills a gap in the literature by providing a thorough and up-to-date assessment of the potential of MAS for logistics and supply chain management. To the best of the authors’ knowledge, this is the first study to investigate the relevance of MAS for logistics network resilience using the Delphi method.

Abstract

Purpose

Blockchain technology is predicted to revolutionize the tourism and hospitality industry through peer-to-peer hotel bookings with little or no involvement of intermediaries. Outstanding features of this technology are its distributed form of storing data, its collaborative way of identifying the “true state” of a system and the immutability of data. These features may lead to a perceived loss of controllability among travelers. Based on the Agentic Theory of Human Behavior, the purpose of this study is to propose that this assumed loss of control matters more to travelers with an individualistic rather than a collectivistic predisposition.

Design/methodology/approach

In two studies (n = 475 and n = 196) using verbal scenarios, this study manipulates the perceived controllability of a blockchain-enabled hotel booking app by varying the number of additional services linked to the app. This study tests for the interaction of controllability with individual-level measures of individualistic versus collectivistic (I-C) predisposition.

Findings

Collectivistic travelers are more willing than individualistic travelers to use blockchain technology for their hotel bookings. This effect can be mitigated by offering additional services that give individualistic travelers an enhanced sense of “being in control”.

Practical implications

Blockchain-enabled applications facilitating direct hotel bookings without any additional intermediary services are more readily accepted by travelers with a collectivistic mindset. Blockchain applications addressing individualistic travelers require added services that establish a sense of controllability.

Originality/value

To the best of the authors’ knowledge, this paper is the first to investigate the interaction of I-C predisposition with perceived controllability in tourism and hospitality. Furthermore, it is the first in the technology-acceptance literature to test this interaction using individual-level measures of I-C predisposition and an experimental manipulation of perceived controllability.

研究目的

预计区块链技术将通过点对点酒店预订彻底改变旅游业和酒店业, 而中介机构很少或根本不参与。该技术的突出特点是其存储数据的分布式形式、识别系统“真实状态”的协作方式以及数据的不变性。这些特征可能会导致旅行者感觉失控。基于人类行为的代理理论, 我们提出这种假设的失控对具有个人主义而非集体主义倾向的旅行者更重要。

研究设计/方法/途径

在两项使用口头场景的研究(n = 475 和 n = 196)中, 我们通过改变与应用程序链接的附加服务的数量来操纵支持区块链的酒店预订应用程序的感知可控性。我们测试了可控性与个人主义与集体主义 (I-C) 倾向的个体水平测量的相互作用。

研究发现

集体主义旅行者比个人主义旅行者更愿意使用区块链技术进行酒店预订。这种影响可以通过提供额外的服务来减轻个人主义旅行者增强了“掌控感”。

研究原创性

本文首次研究了旅游和酒店业中 I-C 倾向与感知可控性的相互作用。此外, 它是技术接受文献中第一个使用 I-C 倾向的个体水平测量和感知可控性的实验操作来测试这种相互作用。

实践意义

研究建议具有集体主义心态的旅行者更容易接受支持区块链的应用程序, 无需任何额外的中介服务即可直接预订酒店。针对个性化旅行者的区块链应用程序需要额外的服务来建立可控感。

Abstract

Purpose

The purpose of this paper is to illustrate how centralization and decentralization of supply chains (SCs) play a major role in creating organizational resilience.

Design/methodology/approach

Starting with the basic tenets of contingency theory and applying a grounded theory approach, results from exploratory qualitative and quantitative studies are combined to investigate the impact of (de)centralization on SC resilience capabilities.

Findings

The findings from a comprehensive literature review combined with two empirical surveys indicate that four important organizational capabilities are needed in order to cope with internal and external disruptions: fast reactions to unforeseen disturbances, reducing the number of negative external forces, reducing the impact of negative external forces and the quick return to normal operating processes. Furthermore, it is illustrated how (de)centralization activities can support these capabilities and thus maximize the SC resilience.

Originality/value

This paper presents 12 measures for (de)centralization and shows how they can support the four major capabilities of resilient companies. The results from qualitative and quantitative surveys allow for a holistic understanding of the organization and provide a basis for future SC resilience research.

Abstract

Purpose

The physical internet (PI) is an emerging logistics and supply chain management (SCM) concept that draws on different technologies and areas of research, such as the Internet of Things (IoT) and key performance indicators, with the purpose of revolutionizing existing logistics and SCM practices. The growing literature on the PI and its noteworthy potential to be a disruptive innovation in the logistics industry call for a systematic literature review (SLR), which we conducted that defines the current state of the literature and outlines future research directions and approaches.

Design/methodology/approach

The SLR that was undertaken included journal publications, conference papers and proceedings, book excerpts, industry reports and white papers. We conducted descriptive, citation, thematic and methodological analyses to understand the evolution of PI literature.

Findings

Based on the literature review and analyses, we proposed a comprehensive framework that structures the PI domain and outlines future directions for logistics and SCM researchers.

Research limitations/implications

Our research findings are limited by the relatively low number of journal publications, as the PI is a new field of inquiry that is composed primarily of conference papers and proceedings.

Originality/value

The proposed PI-based framework identifies seven PI themes, including the respective facilitators and barriers, which can inform researchers and practitioners on future potentially disruptive SC strategies.

The purpose of this study is to investigate the potentials of blockchain technologies (BC) for supply chain collaboration (SCC).

2994

Abstract

Purpose

The purpose of this study is to investigate the potentials of blockchain technologies (BC) for supply chain collaboration (SCC).

Design/methodology/approach

Building on a narrative literature review and analysis of seminal SCC research, BC characteristics are integrated into a conceptual framework consisting of seven key dimensions: information sharing, resource sharing, decision synchronization, goal congruence, incentive alignment, collaborative communication and joint knowledge creation. The relevance of each category is briefly assessed.

Findings

BC technologies can impact collaboration between transaction partners in modern supply chains (SCs) by streamlining information sharing processes, by supporting decision and reward models and by strengthening communicative relationships with SC partners. BC promises important future capabilities in SCs by facilitating auditability, improving accountability, enhancing data and information transparency and improving trust in B2B relationships. The technology also promises to strengthen collaboration and to overcome vulnerabilities related to moral hazard and shortcomings found in legacy technologies.

Research limitations/implications

The paper is mainly focused on the potentials of BC technologies on SCC as envisioned in the current academic literature. Hence, there is a need to validate the theoretical inferences with other approaches such as expert interviews and empirical tests. This study is of use to practitioners and decision-makers seeking to engage in BC-collaborative SC models.

Originality/value

The value of this paper lies in its call for an increased focus on the possibilities of BC technologies to support SCC. This study also contributes to the literature by filling the knowledge gap of how BC potentially impacts SC management.

Abstract

Purpose

This paper aims to strive to close the current research gap pertaining to potential implications of the blockchain for supply chain management (SCM) by presenting a framework built on four established economic theories, namely, principal agent theory (PAT), transaction cost analysis (TCA), resource-based view (RBV) and network theory (NT). These theories can be used to derive research questions that are theory-based as well as relevant for the industry. This paper is intended to initiate and stimulate an academic discussion on the potential impact of the blockchain and introduces a framework for middle-range theorizing together with several research questions.

Design/methodology/approach

This paper builds on previous theories that are frequently used in SCM research and shows how they can be adapted to blockchain-related questions.

Findings

This paper introduces a framework for middle-range theorizing together with several research questions.

Research limitations/implications

The paper presents blockchain-related research questions derived from four frequently used theories, namely, PAT, TCA, RBV and (NT). These questions will guide future research pertaining to structural (PAT, TCA) and managerial issues (RBV, NT) and will foster middle-range theory development in SCM research.

Practical implications

Blockchain technology has the potential to significantly change SCM. Given the huge investments by industry, academic research is needed which investigates potential implications and supports companies. In this paper, various research questions are introduced that illustrate how the implications of blockchain on SCM can be investigated from different perspectives.

Originality/value

To the best of the author’s knowledge, no academic papers are published in leading academic journals that investigate the relationship between SCM and blockchain from a theory-based perspective.

Abstract

Purpose

The purpose of the paper is to critically evaluate the applicability of bio certification in farmers' activity to reduce unfair trading practices in the food supply chain. The secondary purposes are describing the economic reasons of using bio certification and perspectives of using web trading platforms among food producers.

Design/methodology/approach

Data collection included face-to-face interviews with 15 Austrian and German farmers who operate on bio food markets as well as a quantitative survey regarding their assessment of unfair trading practices. This study presents both quantitative and qualitative analyses.

Findings

Bio certification is more likely unable to eliminate or mitigate unfair trading practices in the food supply chain, however bio certification is able to increase efficiency of farmers together with other web tools.

Originality/value

The study is the first to empirically investigate the applicability of bio certifications, its advantages and impact on unfair trading practices in the food supply chain. It focuses on small and medium-sized food producers and farmers. The research also reveals the perspectives of using web trading platforms in farming activity.

Abstract

Purpose

Crowdfunding (CF) has become an increasingly popular means of financing for entrepreneurs and has attracted significant attention from both researchers and practitioners in recent years. The purpose of this study is to investigate the core content and knowledge diffusion paths in the CF field. Specifically, we aim to identify the main topics and themes that have emerged in this field and to trace the evolution of CF knowledge over time.

Design/methodology/approach

This study employs co-word clustering and main path analysis (MPA) to examine the historical development of CF research based on 1,528 journal articles retrieved from the Web of Science Core Collection database.

Findings

The results of the analysis reveal that CF research focuses on seven themes: sustainability, entrepreneurial finance, entrepreneurship, fintech, social entrepreneurship, social capital, and microcredits. The analysis of the four main paths reveals that equity CF has been the dominant topic in the past years. Recently, CF research has tended to focus on topics such as fintech, the COVID-19 pandemic, competition, Brexit, and policy response.

Originality/value

To the authors' best knowledge, this is the first attempt to explore knowledge diffusion dynamics in the CF field. Overall, the study offers a structure for analyzing the paths through which knowledge is diffused, enabling scholars to effectively manage a large volume of research papers and gain a deeper understanding of the historical, current, and future trends in the development of CF.
