Peer-review declarationThe publisher (AOSIS) endorses the South African 'National Scholarly Book Publishers Forum Best Practice for Peer-Review of Scholarly Books'. The book proposal form was evaluated by our Social Sciences, Humanities, Education and Business Management editorial board. The manuscript underwent an evaluation to compare the level of originality with other published works and was subjected to rigorous two-step peer-review before publication by two technical expert reviewers who did not include the author and were independent of the author, with the identities of the reviewers not revealed to the author. The reviewers were independent of the publisher and author. The publisher shared feedback on the similarity report and the reviewers' inputs with the manuscript's author to improve the manuscript. Where the reviewers recommended revision and improvements, the author responded adequately to such recommendations. The reviewers commented positively on the scholarly merits of the manuscript and recommended that the book be published.
