Purpose The purpose of this paper is to explore the application of triglycidyl resin (TGC) prepared from cardanol as partial replacement of conventional bis-phenol A (BPA) based epoxy resin for zinc rich primers (ZRPs). Design/methodology/approach The synthesis of new platform chemicals that are based on renewable resources has been accepted as a strategy to contribute to sustainable development due to the anticipated depletion of fossil oil reserves and rising oil prices. We prepared a tri-functional epoxy resin from cardanol which can be used as partial replacement of BPA based epoxy. The ZRPs were prepared using 50:50 ratio of TGC:BPA epoxy, and the coatings were evaluated for mechanical, chemical and anticorrosive properties. Findings The 50 per cent replacement of BPA based epoxy by TGC resulted in at par mechanical, chemical and anticorrosive properties as evaluated by various methods. The successful implementation can thus contribute to sustainable development by “green chemistry” route. Research limitations/implications The prepared TGC resin in the current work was studied for application in ZRPs. This can also be explored for high performance coatings, adhesives and other engineering applications. Practical implications The TGC binder was prepared by simple two-step reaction. This can successfully be used as binder for coating application without any modifications. Originality/value A novel approach of using green and ecofriendly TGC resin as replacement of high cost BPA based epoxy was explored and can be implemented for numerous applications.

Purpose – Despite the surge of interest in construction sustainability and the many Government initiatives encouraging reform in the UK construction industry (CI), the prevalence of sustainable development (SD) in the industry is still largely lagging behind that of other industries. Given the amount of focus and activity identified nationally in this area, the purpose of this paper is to investigate the reasons why this is not being translated into action and to seek counsel from industry professionals as to how they believe change can be achieved with a particular focus on how they believe higher education institutions (HEIs) can contribute. Design/methodology/approach – An explorative, qualitative study using three focus groups was of construction professionals. Findings – Despite a lack of action, many in industry support sustainability and actively attempt to engage in sustainable practices but a number of barriers preclude successful implementation. Government initiatives are having a positive impact, with participants believing that both Government and HEIs are imperative in driving the sustainability agenda forward. Research limitations/implications – Whilst limited in scale, this paper highlights the current state of the CI in relation to SD and evidences that progress is being made albeit slowly. The findings may help both Government and HEIs alongside industry in achieving how this can be overcome. Originality/value – Previous research in this area has generally adopted a quantitative approach. Adopting a qualitative approach provides a more in depth view as to why the status quo remains with regards to SD in the CI.

PurposeThe risk of adverse events in a hospital evaluation is an important process in healthcare management. It involves several technical, social, and economical aspects. The purpose of this paper is to propose an integrated approach to evaluate the risk of adverse events in the hospital sector.Design/methodology/approachThis paper aims to provide a decision-making framework to evaluate hospital service. Three well-known methods are applied. More specifically are proposed the following methods: analytic hierarchy process (AHP), a structured technique for organizing and analyzing complex decisions, based on mathematics and psychology developed by Thomas L. Saaty in the 1970s; decision-making trial and evaluation laboratory (DEMATEL) to construct interrelations between criteria/factors and VIKOR method, a commonly used multiple-criteria decision analysis technique for determining a compromise solution and improving the quality of decision making.FindingsThe example provided has demonstrated that the proposed approach is an effective and useful tool to assess the risk of adverse events in the hospital sector. The results could help the hospital identify its high performance level and take appropriate measures in advance to prevent adverse events. The authors can conclude that the promising results obtained in applying the AHP–DEMATEL–VIKOR method suggest that the hybrid method can be used to create decision aids that it simplifies the shared decision-making process.Originality/valueThis paper presents a novel approach based on the integration of AHP, DEMATEL and VIKOR methods. The final aim is to propose a robust methodology to overcome disadvantages associated with each method.

ABSTRACT Diamines are important monomers for polyamide plastics; they include 1,3-diaminopropane, 1,4-diaminobutane, 1,5-diaminopentane, and 1,6-diaminohexane, among others. With increasing attention on environmental problems and green sustainable development, utilizing renewable raw materials for the synthesis of diamines is crucial for the establishment of a sustainable plastics industry. Recently, high-performance microbial factories, such as Escherichia coli and Corynebacterium glutamicum, have been widely used in the production of diamines. In particular, several synthetic pathways of 1,6-diaminohexane have been proposed based on glutamate or adipic acid. Here, we reviewed approaches for the biosynthesis of diamines, including metabolic engineering and biocatalysis, and the application of bio-based diamines in nylon materials. The related challenges and opportunities in the development of renewable bio-based diamines and nylon materials are also discussed.

Purpose The purpose of this paper is to demonstrate heroism as an embodied system of leadership and well-being. Heroic leadership is presented as a baseline for sustainable futures and global health. Design/methodology/approach This paper presents an embodied reading of heroic leadership and its sustainable development across five stages. It outlines its core functions, its grounding in self-leadership through physical and mental trauma and its holistic benefits, resulting in the development of the Heroic Leadership Embodiment and Sustainable Development (HLESD) model. The efficacy of HLESD is demonstrated in an empirical case study of heroism promotion and education: the Hero Construction Company and the Heroic Imagination Project. Findings Heroic leadership is revealed as an emergent, dynamic and distributed form of sustainable development. Research limitations/implications This paper demonstrates the critical connections between heroism, sustainability, embodied leadership and well-being and how they stand to benefit from each other, individuals and communities at large. Social implications The implementation of HLESD in educational, counselling and broader contexts in consultation with a wide range of professionals stands to offer significant benefits to pedagogies, clinical practice, holistic therapies and twenty-first-century societies, at both the community and policy level. Originality/value The emerging field of heroism science and the use of heroic leadership as an interdisciplinary tool is a novel approach to well-being, which holds immense potential for the imagining and fostering of sustainable personal and collective futures.

Purpose The purpose of this paper is to explore the current and projected impacts of the three post-2015 development agendas on the underlying disaster risk drivers (UDRD): the Sendai Framework for Disaster Risk Reduction, the Sustainable Development Goals, and the Paris COP21 Agreement. Design/methodology/approach The methodology is based on an ontological process, understood as an exhaustive analysis of the properties and relationships of an entity or subject of study. Findings The process characterized and linked the objectives proposed in the three agendas through the impact of the expected results on the underlying risk drivers. First, elements related to disaster risk within each agenda were identified. Then, in following the theory of change, a series of tools were used to identify domains of change, pathways, breakthroughs, and incremental outcomes that counteract the construction of disaster risk by acting on the underlying causes. It is essential that there be coherence, complementarity, and interdependence between the three agendas analyzed in order to transcend beyond the desired economic growth, and thus underpin true sustainable development by focusing on the UDRD. Originality/value Applying the theory of change constitutes a novel approach to identify the pathways or domains of change needed to integrate the three 2015 development agendas.

Practical Implications

Purpose Due to the strong reliance on element quality, there exist some inherent shortcomings of the traditional finite element method (FEM). The model of FEM behaves overly stiff, and the solutions of automated generated linear elements are generally of poor accuracy about especially gradient results. The proposed cell-based smoothed point interpolation method (CS-PIM) aims to improve the results accuracy of the thermoelastic problems via properly softening the overly-stiff stiffness. Design/methodology/approach This novel approach is based on the newly developed G space and weakened weak (w2) formulation, and of which shape functions are created using the point interpolation method and the cell-based gradient smoothing operation is conducted based on the linear triangular background cells. Findings Owing to the property of softened stiffness, the present method can generally achieve better accuracy and higher convergence results (especially for the temperature gradient and thermal stress solutions) than the FEM does by using the simplest linear triangular background cells, which has been examined by extensive numerical studies. Practical implications The CS-PIM is capable of producing more accurate results of temperature gradients as well as thermal stresses with the automated generated and unstructured background cells, which make it a better candidate for solving practical thermoelastic problems. Originality/value It is the first time that the novel CS-PIM was further developed for solving thermoelastic problems, which shows its tremendous potential for practical implications.
