The training of commercial aircrews in team management is now being recognised as a priority. This article reviews one major intervention with Trans Australia Airlines.

As Canadian crude bitumen production from oil sands has increased in recent decades, the nation's oil and gas industry has become a significant contributor to national greenhouse gas emissions. Canada has developed carbon emission reduction targets to meet its Nationally Determined Contributions and Mid-Century Strategy goals. A detailed profile of energy consumption pathways in the oil sands industry is necessary to identify potential areas of improvement and to monitor progress toward meeting emissions reduction targets. Much of the existing literature for oil sands modeling provides input assumptions with different technological boundaries. For a set of oil sands extraction and upgrading technologies, this study first reviews the literature and then quantifies energy input requirements, CO2 emissions, and operating costs for a set of consistent technological boundaries and energy units. Summary results refer to requirements and costs at the production facility, excluding transportation and blending costs. An energy system diagram of oil sands production that matches these boundaries is provided, which can be used by integrated assessment models, oil sands companies, and government ministries to evaluate the present and future energy consumption and emissions pathways of the oil sands industry.

"This title was first published in 2000: Serving the State is an invaluable two-volume exploration of global trends in public administration education and training. Volume 2 of this important reference work explores traditions and contexts. Included for examination are the French and Islamic traditions, The Netherlands, Scandinavia, Latin America, Small Island States and former communist countries such as Poland and the Ukraine as well as other countries undergoing rapid economic change."--Provided by publisher.

Sustainable consumption is a central research topic in academic discourses of sustainable development and global environmental change. Informed by a number of disciplinary perspectives, this book is structured around four key themes in sustainable consumption research: Living, Moving, Dwelling and Futures. The collection successfully balances theoretical insights with grounded case studies, on mobility, heating, washing and eating practices, and concludes by exploring future sustainable consumption research pathways and policy recommendations. Theoretical frameworks are advanced throughout the

Calls for greater food democracy in Europe have emerged as the limitations of urban food systems dominated by commercial organisations are documented, but little attention has been paid to how policy arrangements affect attempts to transition to more democratic food futures. This article examines food sharing initiatives—increasingly facilitated by the use of information and communication technologies—as a potential means to enhance urban food democracy, and explores the role of policy in shaping those practices in three European capital cities: Berlin, London, and Dublin. We pose two related questions: To what extent are diverse food sharing initiatives exemplars of food democracy, and to what extent do policy arrangements affect food sharing practices and the nature of any food democracy they might embody? Our empirical evidence demonstrates where the goals and impacts of food sharing initiatives align with key dimensions of food democracy. We also consider how food sharing initiatives—and any food democracy dimensions that they support—are affected by the policy environment in which they operate. The food sharing initiatives examined revealed to be agents of pro-democratic change, at least within the boundaries of their spheres of influence, despite policies rarely having their activities and aspirations in mind.

As part of a longitudinal study of the epidemiology of rabbit haemorrhagic disease virus (RHDV) in New Zealand, serum samples were obtained from trapped feral animals that may have consumed European rabbit (Oryctolagus cuniculus) carcasses (non-target species). During a 21-month period when RHDV infection was monitored in a defined wild rabbit population, 16 feral house cats (Felis catus), 11 stoats (Mustela erminea), four ferrets (Mustela furo) and 126 hedgehogs (Erinaceus europaeus) were incidentally captured in the rabbit traps. The proportions of samples that were seropositive to RHDV were 38% for cats, 18% for stoats, 25% for ferrets and 4% for hedgehogs. Seropositive non-target species were trapped in April 2000, in the absence of an overt epidemic of rabbit haemorrhagic disease (RHD) in the rabbit population, but evidence of recent infection in rabbits was shown. Seropositive non-target species were found up to 2.5 months before and 1 month after this RHDV activity in wild rabbits was detected. Seropositive predators were also trapped on the site between 1 and 4.5 months after a dramatic RHD epidemic in February 2001. This study has shown that high antibody titres can be found in non-target species when there is no overt evidence of RHDV infection in the rabbit population, although a temporal relationship could not be assessed statistically owning to the small sample sizes. Predators and scavengers might be able to contribute to localised spread of RHDV through their movements.

Addressing climate change globally requires significant transformations of production and consumption systems. The language around climate action has shifted tangibly over the last five years to reflect this. Indeed, thousands of local governments, national governments, universities and scientists have declared a climate emergency. Some commentators argue that the emergency framing conveys a new and more appropriate level of urgency needed to respond to climate challenges; to create a social tipping point in the fight against climate change. Others are concerned to move on from such emergency rhetoric to urgent action. Beyond emergency declarations, new spaces of, and places for, engagement with climate change are emerging. The public square, the exhibition hall, the law courts, and the investors' forum are just some of the arenas where climate change politics are now being negotiated. Emergent governing mechanisms are being utilised, from citizens' assemblies to ecocide lawsuits. New social movements from Extinction Rebellion to Fridays For Future demonstrate heightened concern and willingness to undertake civil disobedience and protest against climate inaction. Yet questions remain which are addressed in this thematic issue: Are these discourses and spaces of engagement manifestations of a radical new climate politics? And if these are new climate politics, do they mark a shift of gear in current discourses with the potential to effect transformative climate action and support a just transition to a decarbonised world?
