Our analysis includes a specific type of financing — overdrafts — where retailers facing cash constraints can leverage overdrafts to manage unexpected cash shortfalls. To address this issue, we propose a stochastic programming model and solve it using stochastic dual dynamic programming (SDDP). Additional auxiliary variables are introduced in the sub-problems to facilitate the construction of cuts in the presence of lead times. To enhance computational efficiency, we provide two techniques: removing the duplicate added constraints in the model and exploiting dual value similarities of the constraints across sub-problems. Numerical experiments demonstrate that SDDP can solve the problem with small optimality gaps compared to the values obtained from stochastic dynamic programming, and the proposed acceleration strategies significantly reduce computation time with minor impact on solution quality. 2026-04-12T00:00:00Z http://bura.brunel.ac.uk/handle/2438/33093 Title: The politics of (e)valuation in community projects: creating a Living Impact Methodology to pluralise accountability and centre lived experience Authors: Smith, L; Warren, R; Cunningham, C Abstract: ...

It explores the implications of this dynamic environment on marketing strategies, revealing the depth and complexity of consumer behavior in an era defined by constant connectivity and curated online experiences. Design/methodology/approach: This is a conceptual paper built on the emerging body of literature in consumer studies, international marketing, international business, information systems and general management. Findings: We develop a conceptual scaffolding for a novel term, ‘Glocalization of consumer culture’, by delving into scholarly works and industry reports and position it as an integral component of post-global consumer culture. Originality: The paper coins and theorizes a new concept ‘glocalization of consumer culture’ that is built upon a typology of complex political identity and digital consumer culture. Practical implications: The paper offers useful insights into why and how post globalized consumers vary in terms of their attitude toward global and local brands. Accordingly, international marketers can develop useful segmentation and positioning strategies.

Agro-waste reinforcements, including rice husk ash (RHA), coir, bamboo fibre, and wood flour, were examined for their capacity to improve the mechanical and environmental performance of PVC and to advance circular economy objectives. Empirical data from UK PVC window manufacturing were integrated with Granta EduPack, Eco Design, Eco Audit, OpenLCA, and Protégé within a multi-layered semantic pipeline that links materials, processes, and environmental indicators. The agro-filler composites exhibited lower embodied energy and CO2 emissions than glass fibre systems, with the PVC + 30% wood flour formulation achieving the highest efficiency. The ontology framework, comprising 25 classes, 7 object properties, 26 individuals, 16 data properties, and 218 axioms (generated automatically by Protégé’s metrics feature and verified with the Pellet reasoner), ensured semantic interoperability and consistent validation across datasets, enabling transparent and traceable sustainability analysis. Overall, coupling industrial data with digital LCA and ontology reasoning provides a reproducible pathway toward net zero-aligned, sustainable PVC composite manufacturing.
