This paper is concerned with the theoretical and practical engineering development issues, necessary for the design, build and test of an afterburner thrust augmentation system for a model aircraft gas turbine engine.

Research into key combustion parameters including, flame holder diameter, flame holder edge velocity, burner velocity and equivalence ratio were undertaken. This information was used as the basis for the design and fabrication of the afterburner combustion system. The after burner system had been designed to fit a Wren MW54 model gas turbine engine, that included FADEC control for the mother engine. Substantial testing of the afterburner system was undertaken.

Changes in “dry” and “wet” jet efflux temperature while the engine is accelerating from idle to full power are found. The increase in temperature between the dry and wet case are not markedly different, demonstrating the poor quality of the afterburner flame: the testing of the afterburner system resulted in limited flame substantiation being achieved.

Further research is required and is currently being undertaken, into the computational modelling of fuel atomisation issues and further engineering of the fuel injection system.

This afterburner design may eventually be adopted by Wren Turbines for economic production.

Provides further information on the engineering and efficiency problems associated with very small‐scale gas turbine engines.

The restrictive legislation on recruitment in Italy is a well‐known example of state control of a labour market; the means Italian companies employ to get round the legislation is, if anything, even more interesting. Problems are recognised by the government and in mid‐1991 the legislation was “reformed”. A detailed study of the working of the old legislation and the situation which led to its reform concludes that although the latest law is a step forward it amounts to a missed opportunity.

The occupational stress and well-being literature often focuses on specific causes of stress as health risk factors to be managed, on attributes of work environments that are stressful and/or risky, or on prevention and intervention strategies for managing these causes of stress as well as individual stress responses at work (Quick & Tetrick, 2003). The occupational stress literature has not focused on how executives and organizations can cause positive stress for people at work. In this chapter, we explore a principle-based framework for executive action to create positive, constructive stress for people at work.

The first major section of the chapter discusses seven contextual factors within which the principle-based framework is nested. The second major section of the chapter develops nine principles for executive action. The third and concluding section of the chapter turns the focus to a set of guidelines for executive action in managing their personal experience of stress.

This paper aims to set out several of the key issues and areas of the inter‐disciplinary field of climate change research based in accounting and accountability, and to introduce the papers that compose this AAAJ special issue.

The paper provides an overview of issues in the science of climate, as well as an eclectic collection of independent and inter‐disciplinary contributions to accounting for climate change. Through additional accounting analysis, and a shadow carbon account, it also illustrates how organisations and nations account for and communicate their greenhouse gas (GHG) footprints and emissions behaviour.

The research shows that accounting for carbon and other GHG emissions is immensely challenging because of uncertainties in estimation methods. The research also shows the enormity of the challenge associated with reducing those emissions in the near future.

The paper surveys past work on a wide variety of perspectives associated with climate change science, politics and policy, as well as organisational and national emissions and accounting behaviour. It provides an overview of challenges in the area, and seeks to set an agenda for future research that remains interesting and different.

This study aims to investigate which resources and sources of support are related to employee adaptability to work-related change during the COVID-19 pandemic, with implications for human resource management (HRM).

The authors analysed a survey of 1,619 employees working in architectural practice and allied fields in Australia in 2020.

Drawing on conservation of resources (COR) theory, the authors asked whether workers would be more adaptable to change during COVID-19 if they were able to draw on a combination or bundle of supports, known as resource caravans. Hierarchical multiple regression and relative importance analysis showed that confidence in personal support networks during the pandemic was the most important predictor assisting workers to adapt to change, followed by concrete (practical, technical) organizational support for remote work. No evidence was found to corroborate this study's hypotheses that these resources provide support in bundles, challenging the notion of resource caravans in this research context.

The authors argue that COR theory has been too broadly applied to the workplace and that boundary conditions should apply to its emphasis on resource caravans. In practical terms, HRM supports to promote employee adaptability should be carefully targeted in extreme circumstances such as the COVID-19 pandemic.
