Mapping facets of circularity: going beyond reduce, reuse, recycle in agri-food supply chains
No full textThe world is facing increasing economic, environmental, and social sustainability challenges. Agri-food supply chains play an intrinsic part in these as both, heavy users of natural resources and a supplier of essential resources satisfying societal needs. In the context of the circular economy, focusing on Reduce, Reuse and Recycle, (3R waste hierarchy) is no longer sufficient. Here an extension is proposed through rethinking the system, redesigning its infrastructure, processes and products, replacing traditional technologies, materials and energy sources with more effective ones and repurposing or recontextualising the use of products, components and by-products. While principles behind these ‘Rs’ are generally known, their application is industry and material/product specific. Within the agri-food supply chain it is subject to strict food safety regulations, packaging requirements, ethical considerations, etc.In this paper we explore ‘R’ principles discussed in the academic literature, identify ‘8Rs’ concept applicable to biological (e.g., crops, prepared food) and technical flows (e.g., packaging) that appear at agri-food producers and discuss their role in enabling and enhancing circularity in bio- and techno-sphere. We present applications of these ‘Rs’ in four cases relevant to the agri-food sector.<br/

Arbitration and Dispute Settlement in Foreign Indirect Investment. The increasing significance and use of arbitration in international loan agreements, syndicated loans and international bond issues
No full textThis dissertation examines the suitability of arbitration for the resolution of securities regulatory claims and it adoption globally, which has resulted in international arbitration becoming the favoured dispute resolution mechanism in the securities industry. The author explains that disputes arising out of international bilateral and syndicated loan agreements are generally considered to be arbitrable, while international bond disputes are often derived from the controversies over the application of mandatory national laws and the compliance with securities regulation provisions - so the arbitrability of international bond disputes depends on the acceptance of the arbitrability of securities regulatory claims
Investor Relations and Corporate Communications (IRSC) and cost of debt and equity capital
No full textIn this study, we examine whether firms’ engagement in Investor Relations and Stakeholder Communication (IRSC) activities reduce the cost of information asymmetry at the time of external financing. We also analyze the intermediary role of financing source (debt vs equity) and the existing level of firm transparency. Measures of IRSC initiatives are frequency of press releases, frequency of events (conferences and meetings, including industry gatherings as well as investment bank seminars), ratio of question and answer portion to the length of events, the average length of answer per question asked during events, and the frequency of slides used in event presentations. Sample includes 1,190 firms listed on S&P1500 index (small, medium, and large-cap firms on NYSE, AMEX, and NASDAQ stock exchanges) from 1999 to 2018. Multiple regression analyses (with robust standard errors) show that press frequency and the portion of question and answer in events have a significant and positive relationship with the cost of financing and event frequency and the average length of answers have a negative association with the cost of financing. Multivariate multiple regression analyses (seemingly unrelated regression models) are used to control for simultaneous effects of debt and equity issue and show that these findings are more pronounced for firms of lower transparency who are going to issue equity compared to firms of higher transparency who are going to issue debt

No full textChiral superconductivity from repulsive interactions in doped graphene
Full text linkAuthor Manuscript 17 Sep 2011Chiral superconductivity, which breaks time-reversal symmetry, can exhibit a wealth of fascinating properties that are highly sought after for nanoscience applications. We identify doped graphene monolayer as a system where chiral superconductivity can be realized. In this material, a unique situation arises at a doping where the Fermi surface is nested and the density of states is singular. In this regime, d-wave superconductivity can emerge from repulsive electron–electron interactions. Using a renormalization group method, we argue that superconductivity dominates over all competing orders for generic weak repulsive interactions. Superconductivity develops simultaneously in two degenerate d-wave pairing channels. We argue that the resulting superconducting state is of chiral type, with the phase of the superconducting order parameter winding by 4π around the Fermi surface. Realization of this state in doped graphene will prove that superconductivity can emerge from electron–electron repulsion, and will open the door to applications of chiral superconductivity
