      Reducing the food waste is the greatest challenge in the present times for sustainable food management systems that have significant economic, environmental and social impact on the food supply chain. The Circular Economy (CE) paradigm advocates the concept of the closed-loop economy endorsing more responsible utilization and appropriate exploitation of resources in contrast to the open-ended linear economic system of take-make-use and dispose. This chapter has explored Agri-Food waste in the context of CE, triple bottom line (TBL), and sustainability. An alignment of circular strategies with the food waste hierarchy is proposed that indicates practical application of the gradations of circularity in the food waste management that could lead to the development of sustainable food management system targeting the sustainable development goals of Zero Hunger and Responsible consumption and production. This chapter also highlights some opportunities and challenges of Agri-Food waste in the application of circular bio-economy.

      Modern Supply Chains are critical in terms of efficiency, economic activities and commercial impact, particularly in case of security incidents. Inland terminals, commercial ports and dry ports constitute key gateways for the transportation flows in these modern supply chains and are require enhanced security procedures. This paper develops a framework that facilitates the sharing of information among various supply chain stakeholders, which is expected to improve the security level from a value chain perspective. In this context, we propose the upgrade of the current security strategies utilizing existing processes, equipment in order to minimise time and cost currently needed but more importantly improving the level of security in the supply chain. A conceptual rule and role-based data fusion framework is developed enabling the seamless and timely exchange of messages. The proposed Data Fusion Framework has a simple architecture that supports quick integration to either network-based, distributed systems or conventional stand-alone systems and adheres to common data fusion principles. The proposed framework considers different components (e.g. sensors, algorithms and fusing procedures) in an equipment agnostic approach so as to enable easy access and easy usage of security information.
    • Decreasing investment-cash flow sensitivity: Further UK evidence

      Using publicly listed firms in the UK, we examine the time-series variation of investment-cash flow sensitivity after directly controlling for future growth opportunities in cash flow, which if overlooked, as in the literature, could bias inferences. We find that investment-cash flow sensitivity is disappearing over time, even for constrained firms during the global financial crisis when credit constraints were more significant or binding. Our results not only confirm the decline in investment-cash flow sensitivity that is not explained by factors so far identified in the literature but also its diminishing usefulness as a proxy of financial constraints.
