| Research questions/objectives | The objective of this study is to explore the labor acquisition trends that attract most companies and to describe critical global supply chain sourcing decisions for the labor supply in Africa. | What is the impact of environmental uncertainty, power asymmetry and information sharing on opportunism engagement in the agricultural and non-agricultural manufacturing sectors in a developing economy? What contextual factors within the agricultural and non-agricultural sector manufacturing sector and the national context influence the impact of the identified antecedents on opportunism in a developing economy? | What challenges exist between South African automotive manufacturers and their suppliers, and how are these challenges related? | What are the critical success factors in the supply chain management of essential medicines, and how significant are they to the public pharmaceutical supplies system in Malawi? |
