The field of applied linguistics is increasingly adopting open science practices. As open access publication gains traction, ethical issues emerge that need to be addressed by the field. This viewpoint paper addresses the concern that open science is not equally open for everyone. This paper describes how open access publication is increasingly being commercialized and explains how open access publication coincides with systemic inequality. We offer the following viewpoints for the field to consider:1.) We are morally obligated to make our research output accessible.2.) Hybrid, Gold, and Green open access publishing lead to systemic inequality in open access publishing, benefiting commercial publishers and those working in research-intensive universities and rich countries.3.)Diamond open access publication removes the systemic inequalities; hence, Diamond open access should be prioritized over Hybrid, Gold, and Green open access publication models.4.)We should move away from publish-and-read agreements and Green open access publishing, because they prevent system change.5.)Through our choices in our work as researchers, editors, reviewers, authors and teachers, we can contribute to the transition towards truly equitable open access publishing practices.6.)Senior researchers are in the position and have the moral obligation to be drivers of these changes.

Recent years have seen a global rise in the failure of tailings dams. Studies investigating the causes of slope failure often recognise high intensity rainfall events to significantly contribute to liquefaction, erosion and overtopping. This study aims to investigate the influence of alternative physical and geohydrological processes that, under tension saturation conditions, contribute to slope instability in tailings dams. It has been suggested that the generation of transient pressure wave mechanisms by high intensity rainfall events, surface ponding and wetting front advancement result in the formation of an induced pressure head that triggers the mobilization of pre-event water. In order to quantify these physical processes, this study included the analysis of rapid transmission conditions in a silica fines mix, with similar physical and hydraulic characteristics as platinum tailings. A tall leak-proof soil column, containing the soil sample compacted to in-situ dry bulk density, was fitted with seven observation ports. Each port consisted of a pore air pressure probe, a mini tensiometer and a time domain reflectometry probe. After set-up and initial stabilisation, three separate artificial high intensity rainfall events were applied to the surface. Monitoring of hydraulic state variables was recorded at thirty second intervals by automatic logging, thereby enabling the analysis of measured outcomes. Observations showed instant spikes in pore air pressure ahead of the wetting front, as well as a number of delayed responses. The interpretation of lab results led to the conclusion that pressure diffusion mechanisms throughout the porous medium, could result in the rapid release and mobilisation of previously stagnant antecedent moisture, thereby enabling phreatic levels to rising rapidly and in excess to the amount of surface infiltration. Also, since an increase in pore water pressure is likely to cause a reduction in shear strength, it is suggested that these physical and geohydrological processes could have an adverse impact on the stability of tailings dams.

Increasingly, entrepreneurial growth is discussed in relation to business sustainability and the wider questions of ‘growth’ – economic, green, or sustainable. This chapter will discuss the challenges and opportunities of teaching circular economy and Cradle to Cradle (C2C) models of sustainable production. The course applying circular economy theory to corporate case studies at the liberal arts college in The Netherlands will be discussed. Students were given the assignment to advise an existing company how to make a transition from a linear to circular economy model. https://doi.org/10.1108/978-1-78714-501-620171028 LinkedIn: https://www.linkedin.com/in/helenkopnina/
