This paper responds to recent calls for methodological diversification and “in-house” theory development within the discipline of SCM, by introducing discourse analysis to readers of the Journal of Supply Chain Management. One of the merits of discourse analysis is the way in which it “problematizes” taken-for-granted aspects of organizational life, including supply chains, to show that what we assume to be natural, inevitable and beneficial is rarely quite so straightforward as it may seem. In addition, through the way in which it emphasizes the interrogation of meaning, discourse analysis can broaden conceptualizations of the supply chain to include actors that have previously been overlooked, such as employees, workers, not-for-profit organizations, regulators, consumers, and the media. Using examples that are familiar to SCM researchers—the discourses of lean, sustainability, modern slavery, and big data—we illustrate how discourse analysis can help to theorize SCM phenomena by problematizing established meanings and revealing how they reproduce power relations among actors. We then show how insights from discourse analysis can complement existing theories of the supply chain and, in so doing, potentially rejuvenate the field of SCM by inspiring novel theory development, opening up different empirical settings, and promoting new ways of analyzing qualitative data.

We study the relationship between supplier involvement in new product development and performance. The current literature is scattered and fragmented with studies reporting mixed empirical evidence for a variety of concepts related to “Early Supplier Involvement.” We conduct a systematic review and meta-analysis of the existing literature to reconcile conflicted findings, revise and refine theoretical perspectives, and provide evidence-based scholarly and practical implications. To achieve these aims, we unravel the general relationship by considering three factors. First, we delineate different types of performance outcomes, mainly related to NPD efficiency (e.g., speed) and NPD effectiveness (e.g., product quality). Second, we distinguish between the moment and the extent of supplier involvement, related to different theoretical perspectives on external knowledge integration. Third, we disentangle multiple levels of analysis that are seemingly obscured in the literature, specifically the project and organizational levels. We find that extensive supplier involvement has positive effects on NPD efficiency and effectiveness, whereas earlier supplier involvement only to some degree affects NPD efficiency and not effectiveness. In conclusion, our meta-analysis based on 11,420 observations from 51 studies provides strong theoretical and practical insights on the important phenomenon of supplier involvement.

Supply chain risk management has received considerable attention as firms experience more frequent and severe impact disruptions. We meta-analytically test the Bode et al. (2011) framework of buffering and bridging supply chain risk management strategies to determine their effect on supply chain risk management. We analyze the supply chain risk management literature to find that both buffering and bridging strategies contribute to supply chain risk management. We also address the benefit of supply chain risk management. Results indicate that supply chain risk management provides a strong contribution to overall firm performance. Additionally, we identify cultural differences of these relationships. Although supply chain risk management strategies may be applied universally, their efficacy varies by culture. In conclusion, we identify and provide guidance for future work.

As organizations are increasingly challenged to find new sources of profit improvement, cost reduction becomes a top priority on the business agenda. Expectations for cost reductions are ongoing and influence both new and existing products and services. The costs for new product and service introductions are managed differently than ongoing cost reductions. Purchasing plays a central role, with different goals, in cost control for new products and services versus ongoing cost savings. This research uses a case study methodology to understand the conflict purchasing faces in managing both new product costs and ongoing cost reductions. Due to goal incongruence between new product development and ongoing savings initiatives, purchasing may act in its own best interest, rather than in the best interest of the organization or team. This is both a contracting and an information uncertainty problem, creating an opening for passive opportunism by purchasing. Thus, agency theory and information processing theory (IPT) are combined to examine how information uncertainty can be reduced and contractual goal alignment improved in these situations. The outcome of this research is to expose potential goal misalignment between new product development cost processes and ongoing cost savings, and suggest theoretically grounded methods for reducing the potential conflict.

This study investigates the imitative use of management practices across a multitier supply network. Although imitation may take the form of any management practice, operationally, we focus on whether the buyer’s control practices used with first-tier suppliers results in similar control practices being used by these first-tier suppliers with the second-tier suppliers. Drawing on institutional theory, we identify relational context (i.e., affective commitment) and environmental context (i.e., environmental uncertainty) as two important factors influencing the extent to which such imitation takes place. Using unique survey data of vertically linked supply chain triads, we generally find support for the occurrence of imitation and more so in cases of high affective commitment. The results regarding environmental uncertainty further reveal selectivity in imitative behavior, calling attention to the level of deliberateness in imitation decisions in supply networks. Besides contributing to theory on imitative behaviors in the supply chain, this study also generates practical implications on the spread of management practices across multiple tiers.

Opportunism is a core issue in supply chain management. However, assumption-omitted testing and a focus on general opportunism as opposed to specific forms of opportunism have stubbornly limited our understanding of this construct. Grounded in a review of empirical studies of opportunism, we identify empirical challenges that perpetuate conceptual limitations in the study of opportunism in supply chains. Hence, we provide suggestions about research designs and data sources that support an agenda that steers research to refine and develop the theory about opportunism. Our call for a reinvigoration of the study of opportunism supports rigor—by discussing research design and data sources—and relevance—by identifying topics for future supply chain research.

Heavy metals are a growing threat to human health due to the resulting damage to the ecology; the removal of heavy metals by lactic acid bacteria (LAB) has been a focus of many studies. In this study, 10 LAB strains were evaluated for their ability to absorb and tolerate lead. Lactobacillus plantarum YW11 was found to possess the strongest ability of lead absorbing and tolerance, with the rate of absorption as high as 99.9% and the minimum inhibitory concentration of lead on YW11 higher than 1000 mg/L. Based on the isobaric tags for relative and absolute quantitation (iTRAQ) proteomics analysis of YW11, a total of 2009 proteins were identified both in the lead-treated strain and the control without the lead treatment. Among these proteins, 44 different proteins were identified. The abundance of 25 proteins increased significantly, and 19 proteins decreased significantly in the treatment group. These significantly differential abundant proteins are involved in the biological processes of amino acid and lipid metabolism, energy metabolism, cell wall biosynthesis, and substance transport. This study contributed further understanding of the molecular mechanism of L. plantarum in the binding and removal of lead to explore its potential application in counteracting heavy metal pollution of environment, food, and other fields.

This study investigates how knowledge diffusion occurs in a globally dispersed supply network, wherein buying firms and suppliers often do not have strong relationships and competitive tensions prevail. We elaborate the Network of Practice (NoP) view by examining a global supply network in the food sector that is as an exemplar of high global dispersion. This paper provides several novel insights into global knowledge diffusion. We introduce the NoP concept of homophily into the field of supply chain management to explain knowledge diffusion within global supply networks. We take a longitudinal perspective to show that although prior contractual ties (relational homophily) and co-location (location homophily) initially drive knowledge diffusion, in the long-term, shared practices (practice homophily) are the principal driver of knowledge diffusion. We demonstrate that buying firms’ assurance of procedural justice, together with the predominance of geographically dispersed suppliers and the emergence of nexus members, can help dampen supplier resistance to knowledge diffusion. The study shows that knowledge diffusion in a global supply NoP occurs in two complementary forms—broadcasting forums and action groups—which vary in breadth, depth, and tie diversity. Ultimately, we present vertical (buyer-supplier), horizontal (suppliersupplier), and diagonal (non-competitive) relationships as important refinements of the NoP view that characterize a global supply NoP. Overall, our findings offer a path for buying firms to establish adequate online infrastructure to support the emergence of decentralized and self-organized knowledge diffusion in a globally dispersed supply network.
