The past, present and future of organization development:taking the long view
Organization development has been, and arguably still is, the major approach to organizational change across the Western world, and increasingly globally. Despite this, there appears to be a great deal of confusion as to its origins, nature, purpose and durability. This article reviews the ‘long’ history of organization development from its origins in the work of Kurt Lewin in the late 1930s to its current state and future prospects. It chronicles and analyses the major stages, disjunctures and controversies in its history and allows these to be seen in a wider context. The article closes by arguing that, although organization development remains the dominant approach to organizational change, there are significant issues that it must address if it is to achieve the ambitious and progressive social and organizational aims of its founders

Global assessment of marine plastic exposure risk for oceanic birds
Plastic pollution is distributed patchily around the world's oceans. Likewise, marine organisms that are vulnerable to plastic ingestion or entanglement have uneven distributions. Understanding where wildlife encounters plastic is crucial for targeting research and mitigation. Oceanic seabirds, particularly petrels, frequently ingest plastic, are highly threatened, and cover vast distances during foraging and migration. However, the spatial overlap between petrels and plastics is poorly understood. Here we combine marine plastic density estimates with individual movement data for 7137 birds of 77 petrel species to estimate relative exposure risk. We identify high exposure risk areas in the Mediterranean and Black seas, and the northeast Pacific, northwest Pacific, South Atlantic and southwest Indian oceans. Plastic exposure risk varies greatly among species and populations, and between breeding and non-breeding seasons. Exposure risk is disproportionately high for Threatened species. Outside the Mediterranean and Black seas, exposure risk is highest in the high seas and Exclusive Economic Zones (EEZs) of the USA, Japan, and the UK. Birds generally had higher plastic exposure risk outside the EEZ of the country where they breed. We identify conservation and research priorities, and highlight that international collaboration is key to addressing the impacts of marine plastic on wide-ranging species
