This chapter dives deeper into how the circular economy is important for the tourism industry in the United Arab Emirates (UAE). In a region known for its remarkable growth and innovative endeavors, this chapter meticulously investigates how the principles of the circular economy hold the potential to not only shape the trajectory of sustainable development but also to become a catalyst for heightened economic growth and an embodiment of environmental stewardship within the UAE's dynamic tourism sector. It begins by explaining the multifaceted concept of the circular economy and its compelling relevance to the diverse realm of tourism. It also emphasizes the role of community involvement in making these principles work. The chapter showcases successful case studies in UAE's tourism sector, from eco-friendly hotels to innovative food services and community-based tourism. Finally, it ends with recommendations for stakeholders to work together for sustainable tourism development. As the chapter draws toward a conclusion, it ends with a collection of recommendations that underscore the essence of collaborative engagement among stakeholders – a driving force that is poised to propel the narrative of sustainable tourism development forward with unwavering resolve and unwavering impact.

A key characteristic of powder bed fusion for polymers is that also the non-processed powder in the powder bed is exposed to elevated temperatures. This alters the properties of the remaining powder, which is compensated by refreshing the used powder with new powder. Nonetheless, it is discarded after a certain number of process iterations, which is economically and ecologically highly disadvantageous. Research works intensively to analyse and reduce the concurring effects responsible for powder ageing. This study aims to give a comprehensive overview of the cumulative changes in the powder and the printed parts when conducting several subsequent build cycles.

New polyamide powder (PA12) was used in a total of nine subsequent build cycles with constant sintering parameters and without powder refreshing. After each iteration, the powder and parts were tested for their morphological, thermal and rheological properties.

The results are related to three main changes in the powder during the build cycles: decreasing bulk density (through agglomeration), increasing melt viscosity (through polyamide post-condensation) and increasing melting peak and onset temperatures (through thermal annealing of the powder).

Even though the ageing of PA12 powder in powder bed fusion is well-known, it is not yet fully understood. Studies are not complete and due to different ageing conditions only partially comparable. The detailed study aims to help understand the related effects of powder ageing for process-relevant properties and to show which factors require control to limit the powder ageing.

Staff in secure mental health-care settings face unique occupational challenges that may conflict with their personal or professional moral code. Initial research has established the presence of moral injury in this population, though insight into the specific sources and driving factors at the root of this syndrome is limited. The purpose of this study was to identify potentially morally injurious events and associated risk factors for secure mental healthcare staff.

To address this gap, a three-round expert Delphi survey was conducted to gain consensus on the conceptualisation, types and drivers of potentially morally injurious experiences (PMIEs) for secure mental health-care workers. Health-care professionals and academics in the field were recruited.

A high level of consensus (= 80%) was achieved on several sources of moral injury, which related to aspects of the health-care system, the secure context, relational dynamics and individual practices, behaviours and attitudes. Experts also agreed on several items relating to the definition of a PMIE, the factors driving the occurrence of PMIEs and the factors increasing risk for the subsequent development of moral injury.

The findings suggest that current definitions of PMIEs may, in isolation, be too narrow, prompting the need to attend to the broad range of PMIEs experienced by secure mental health-care staff. In addition, recommendations for the primary and secondary prevention of moral injury in secure mental health-care staff are offered, recognising the particular need for intervention at a systemic level.

To the best of the authors’ knowledge, this study is the first to consider the range of sources of moral injury faced by staff providing for people with complex forensic and mental health needs.

Just transition is a fundamental concept for supply chain management but neither discipline pays attention to the other and little is known about how supply chains can be orchestrated as socioecological systems to manage these transitions. Building from a wide range of just transition examples, this paper explores just transition to understand how to move beyond instrumental supply chain practices to supply chains functioning in harmony with the planet and its people.

Building from a systematic review of 72 papers, the paper identifies just transition examples while interpreting them through the theoretical lens of supply chain management, providing valuable insights to help research and practice understand how to achieve low-carbon economies through supply chain management in environmentally and socially just ways.

The paper defines, elaborates, and extends the just transition construct by developing a transition taxonomy with two key dimensions. The purpose dimension (profit or shared outcomes) and the governance dimension (government-/industry-led versus civil society-involved), generating four transition archetypes. Most transitions projects are framed around the Euro- and US-centric, capitalist standards of development, leading to coloniality as well as economic and cultural depletion of communities. Framing just transition in accordance with context-specific plural values, the paper provides an alternative perspective to the extractive transition concept. This can guide supply chain management to decarbonise economies and societies by considering the rights of nature, communities and individuals.

Introducing just transition into the supply chain management domain, this paper unifies the various conceptualisations of just transition into a holistic understanding, providing a new foundation for supply chain management research.
