This paper aims to provide insights into the environment needed for advancing a digitally enabled circular plastic economy in Africa. It explores important technical and social paradigms for the transition.

This study adopted an interpretivist paradigm, drawing on thematic analysis on qualitative data from an inter-sectoral engagement with 69 circular economy stakeholders across the continent.

The results shows that, while substantial progress has been made with regard to the development and deployment of niche innovations in Africa, the overall progress of circular plastic economy is slowed due to relatively minimal changes at the regime levels as well as pressures from the exogenous landscape. The study highlights that regime changes are crucial for disrupting the entrenched linear plastic economy in developing countries, which is supported by significant sunk investment and corporate state capture.

The main limitation of this study is with the sample as it uses data collected from five countries. Therefore, while it offers a panoramic view of multi-level synergy of actors and sectors across African countries, it is limited in its scope and ability to illuminate country-specific nuances and peculiarities.

The study underlines the importance of policy innovations and regulatory changes in order for technologies to have a meaningful contribution to the transition to a circular plastic economy.

The study makes an important theoretical contribution by using empirical evidence from various African regions to articulate the critical importance of the regime dimension in accelerating the circular economy transition in general, and the circular plastic economy in particular, in Africa.

Regarding today’s volatile and turbulent markets accompanied by natural disasters and political upheavals, being resilient has become crucially important for many firms. It is widely accepted that the firm’s operations need to be cost efficient as well as customer responsive. Lean and agile have been proven to be pertinent strategies toward efficiency and responsiveness. But the operations also need to be resilient against disruptions to quickly return to their original state or even a better one. While the question of how leanness and agility impact operational performance outcomes has been researched, the question of how resilience can boost operational performance outcomes is yet to be investigated. The purpose of this paper is to show how resilience is distinguished from leanness and agility. It then examines the impact of resilience, along with leanness and agility, on operational performance outcomes.

A structural model is drawn up based on the literature to relate lean, agile and resilient practices to performance outcomes. Leanness, agility and resilience are measured through bundles of practices and operational performance outcomes are measured in terms of cost, quality, delivery, flexibility and time to recovery. The model is tested using SPSS 19 and AMOS 19 based on the data collected via survey from a sample of 151 automotive parts suppliers.

The results show that a higher level of resilience will lead to a better performance in terms of delivery, cost and time to recovery, while it does not have a significant impact on flexibility performance. Regarding leanness, the results confirm that lean operations positively affect cost, delivery and flexibility performances. The results also reject the hypothesis stating that higher level of leanness will lead to worse recovery performance, inferring that higher level of leanness leads to better time to recovery performance (i.e. helps time to recovery reduction).

The present research emphasizes the importance of operations resilience and demonstrates its contribution, alongside leanness and agility, to operational performance. The developed structural model contributes to the nascent theories around resilience, and the use of empirical data makes the results valuable practically. This may inform operations strategy decisions in terms of the results expected from resilience, leanness and agility.

This study analyzes the role of supply chain ambidexterity (SC-Ambidexterity) in developing supply chain resilience (SC-Resilience). We describe SC-Ambidexterity as a simultaneous application of supply chain adaptability (SC-Adaptability) and supply chain alignment (SC-Alignment) capabilities. We also consider the role of supply chain agility (SC-Agility) in the relationship between SC-Ambidexterity and SC-Resilience. We further suggest that the relationship between SC-Ambidexterity and SC-Resilience may be stronger in case of higher market uncertainty.

Based on the dynamic capabilities view (DCV) of the firm, we develop a set of hypotheses that are tested through a survey of manufacturing firms in Pakistan. The hypothesized model is tested through structural equation modeling (SEM).

The results of this study show a positive effect of SC-Ambidexterity on SC-Resilience. SC-Agility positively mediates the relationship between SC-Ambidexterity and SC-Resilience. However, our results show that this relationship does not vary at different levels of environmental uncertainty.

This study provides the seminal operationalization of SC-Ambidexterity in the supply chain context. It further shows the importance of SC-Ambidexterity and SC-Agility in contributing toward SC-Resilience.

This paper aims to address Passive Design Strategies (PDSs) in the traditional houses of Sabzevar and to assess the adaptation level of these strategies to the climate of the region.

Identifying the Sabzevar climate, five samples of traditional houses have been chosen to be analyzed via two stages. In stage one, the efficiency of each strategy is weighted through qualitative analysis, and in stage two, the houses are simulated in EnergyPlus 9.3.0 to quantitatively evaluate their heating and cooling performances.

The obtained results from the energy performance analysis of the case studies indicate that the houses present diverse energy performances in different seasons. Those buildings with PDSs for both cold-arid and hot-arid climates, however, are more adaptable cases to the climate of the region.

The results of this study are expected to provide a basis of materials and methods for the climatic assessment of the traditional buildings, specifically traditional houses and will open new doors to future studies about the integration of these potential PDSs with the new technological developments and climate considerations as well as protecting the conservation policies of these buildings by means of optimizing and improving their energy performance and implementing effective retrofit scenarios.
