This paper addresses questions of how extant research discourses concerning the sustainability of supply chains contribute to understanding about circularity in supply chain configurations that support restorative and regenerative processes, as espoused by the Circular Economy ideal. In response to these questions, we develop a content-based literature analysis to progress theoretical body of knowledge and conceptualise the notion of a circular supply chain. We derive an archetypal form from four antecedent sustainable supply chain narratives – ‘reverse logistics’, ‘green supply chains’, ‘sustainable supply chain management’ and ‘closed-loop supply chains’. This paper offers five propositions about what the circular supply chain archetype represents in terms of its scope, focus and impact. Novel insights lead to a definition of circular supply chain and a more coherent foundation for future inquiry and practice.

The omni-channel, as an emerging trend in retail, aims to coordinate processes and technologies across supply and sales channels. The evolution of this concept is still nascent. This paper develops a conceptual framework for omni-channel systems, configured by three dimensions of channel stage, channel type and channel agent. Integration and visibility are also explored and discussed as the main enablers, which support the implementation of omni-channel framework. This research is built upon the empirical and secondary data. Multiple case studies and expert interview methods are employed for data collection to validate the recommended framework and to explore its applicability. The framework proposed, along with the key integration and visibility enablers identified for the omni-channel, can be applied to a wide range of retail supply chains. It helps managers to develop, run and monitor omni-channel systems; it may also serve as a stepping-stone for development of the literature on omni-channel systems

Today, millions of people from around the globe play online role playing games (MMORPG), in which a large number of players interact with one another in a virtual world, either using their existing identities in the physical world, or more often than not, through new virtual identities that might not even be remotely linked to the identities of the players in the physical world. The number of users is growing at an exponential rate and we are probably on the verge of a new development that is going to be as significant as the Internet itself. This positioning paper will discuss the business opportunities and challenges of such a virtual world, that of Second Life , and will examine the resultant corporate social responsibility implications focusing on the ethical and policy-related ones. This will help to identify important research questions that need to be systematically addressed.

Blockchain technology has received significant attention from the food industry; however, due to the scarcity of successful Blockchain projects and sector-specific studies, a step-by-step approach for implementing Blockchain in food supply chains (FSCs) is still missing. A systematic literature review of 69 high-quality, peer-reviewed articles is utilized to capture Blockchain adoption drivers and barriers, applications, and implementation stages within FSCs. Current Blockchain issues such as scalability, regulations, privacy, and incentivization are identified as future research opportunities. Following innovation adoption theory, a three-stage conceptual framework for Blockchain implementation in FSCs is developed. The proposed framework is novel and is expected to benefit food chain managers in establishing the suitability of Blockchain for their organization and/or wider supply network. Identified influential factors, case examples, and implementation stages are expected to guide practitioners in developing a roadmap for adopting Blockchain in the food industry.

Purpose: This paper aims to investigate the evolution from corporate social responsibility to supply chain responsibility via the examination of Waitrose, a leading UK food retailer. These two concepts differ substantially and illustrate contrasting approaches in terms of social responsibility development and application.Design/methodology/approach: A qualitative case study methodology is used where managers from Waitrose and its suppliers, industry experts and representatives from professional bodies are interviewed. An observation of an ethical audit with a Waitrose supplier was also conducted.Findings: Findings show an example of good practice in the area of corporate social responsibility in the supply chain and illustrate the substantive progress that can be made in achieving supply chain responsibility. At the same time, the paper provides the specific challenges in developing from a corporate social watchdog approach to one in which the power in the chain is more balanced and where a holistic approach requires to be taken to achieve social responsibility.Originality/value: Considering the scarcity of work examining empirically the issue of corporate social responsibility in food supply chains, this study demonstrates an evolutionary process and its stages based on an examination of Waitrose's supply chain and the corporate social responsibility approach it has taken with its suppliers. The authors also illustrate a range of key implications that need to be considered by both managers and policy makers and it provides a range of areas where further research is required.
