This paper is based on the Lanchester Lecture of the Royal Aeronautical Society held in London, UK, in October 2023. The lecture discussed the advances in computational modeling of separated flows in aerospace applications since Elsenaar’s Lanchester Lecture in 2000. Elsenaar’s efforts focused on assumptions primarily associated with separation for steady inflow and a static (non-moving) vehicle or component. Since that time, significant advancements in computational hardware, coupled with substantial investments in the development of algorithms and solvers, have led to important breakthroughs in the field. In particular, computational aerodynamics techniques are currently applied to complex aerospace problems that include unsteady or dynamic considerations, such as dynamic stall and gusts, which are discussed. A perspective of the technology developed over the past quarter-century, highlighting their importance to computational aerodynamics is discussed. Finally, the potential of future areas of development, such as machine learning, that may be exploited for the next generation of computational aerodynamics applications is explored.

The global population is ageing rapidly, emphasising the need to understand the decision-making processes of older adults regarding potential care transitions. Gerontological research has focused on healthcare decisions, with less information on living situation choices of older adults. This review explored older adults’ experiences with their involvement in decision-making processes related to transitioning into care facilities in the United Kingdom. From a systematic search of articles, nine were reviewed using thematic narrative synthesis. Four themes with nine subthemes were identified: Involvement in decision-making (Exclusion of older adults, Usefulness of involvement), The necessity of moving (Triggers for moves, The role of family), Timely planning (Helpfulness of planning, Planning avoidance), and Factors for choosing a care home (Non-quality factors, Quality factors, Continuity of life). These themes highlighted the issue of inadequate involvement of older adults in decision-making, often resulting in negative consequences like regret and difficulty settling into new care settings. The necessity of moving arose from sudden events or increased support needs. Some older adults acknowledged the necessity due to declining health or to spare family burden, while relatives grappled emotionally, postponing the choice. Timely planning was found to be beneficial practically and emotionally, facilitating smoother transitions. However, participants would rarely plan and discuss such matters early. Older adults focused on personal experiences and trusted sources rather than publicly available information when considering Factors for choosing a care home. The findings show the need for greater inclusion of older adults in decisions related to their care and the importance of early planning and providing preferred types and formats of information to aid decisions. Future research should focus on a better understanding of older adults’ preferences for successful involvement in care decisions, with support and guidance for others involved in the decisions.

The transition from primary to secondary school, encompassing the pre-, during-, and post-transition stages, often poses significant challenges for students on the autism spectrum. This critical period has garnered growing research attention; however, the perspectives of Australian parents on the support their autistic children receive post-transition remain largely unexplored. Underpinned by a transcendental phenomenological epistemology and Kohler’s Taxonomy for Transition Programming, we explored Australian parents’ perspectives on the support being provided to their children on the autism spectrum and how these students experience this post-transition period. Four parents of high-school-aged children on the autism spectrum participated in interviews, conducted online via Zoom. A deductive content analysis of parents’ insights revealed overwhelming dissatisfaction with the post-transition support provided to their children on the autism spectrum, particularly surrounding home–school collaboration practices and the utilisation of personalised learning. The findings contribute a much-needed Australian perspective to the limited body of research focused on sustaining support for students on the autism spectrum beyond the initial transition to secondary school.

Regenerative involution is crucial for renewing the mammary gland and maximizing milk production. However, the temporal profiles indicators of oxidative status during this phase are still unclear. In this study, Experiment 1 aimed to investigate the dynamic changes in indicators of oxidative status in plasma during regenerative involution. The dairy goats were dried off at 8 weeks (wk) before kidding (−8 wk, n = 14) or −12 wk (n = 6). The blood samples taken at −8, −7, −6, −5, −4, −3, −2, −1 wk, on the day for kidding (0 wk) and the first week after kidding (+1 wk, milk production 1.28 ± 0.31 kg per day). Experiment 2 aimed to investigate the dynamic changes in indicators of oxidative status in mammary cells. Seven selected goats were biopsied for tissue collection and cell isolation at −8, −4, −1, +1 wk (milk production 1.28 ± 0.31 kg per day), respectively. Plasma analysis in Experiment 1 showed an increase in reactive oxygen species (ROS) levels, peaking at −4 wk (P < 0.01). No significant differences were observed between the dry-off treatments (P = 0.36). The activity of superoxide dismutase (SOD) in plasma remained stable from −7 wk to the first week after kidding (+1 wk), while glutathione peroxidase (GSH-Px) activity peaked at −4 wk. An increased catalase activity was observed at +1 wk (P < 0.01), indicating its response to lactation. In Experiment 2, an increase in ROS levels in isolated mammary cells was observed at −4 wk, while SOD, GSH-Px, and malondialdehyde levels in tissue homogenates rose around kidding (P < 0.01). The dynamic change of the oxidative status suggests that targeted antioxidant strategies would be helpful for regenerative involution of mammary gland in ruminants.

Film offers untapped potential for making critical interventions in world politics, particularly in ways that harness people’s capacity to narrate stories that creatively empower their communities. Combining International Relations scholarship on visual politics with narrative theory and feminist scholarship on care, this paper presents film as a means of exploring and expressing narrative agency; that is, the power to tell stories that represent people’s experiences in ways that disrupt hegemonic narratives. Dialectics of care and narrative agency are explored in the context of military-to-civilian ‘transition’ in Britain. We argue that the landscape of transition for military veterans is dominated by a preoccupation with employment and economic productivity, resulting in a ‘care deficit’ for veterans leaving the military. Through the Stories in Transition project, which used co-created film to explore narrative agency in the context of three veterans’ charities, we argue that the act of making care visible constitutes a necessary intervention in this transitional landscape. Grounding this intervention within feminist care ethics and the related notion of care aesthetics, we highlight the potential for film to reveal in compelling audio-visual narratives an alternative project of transition which might better sustain life and hope in the aftermath of military service.

Can United Nations peace operations improve their effectiveness and strengthen longer-term positive legacies in host nations by shifting to greater use of renewable energy? Since the end of the Cold War and the growth of modern UN peace operations, attention has been focused on the missions’ mandate of supporting political strategies for peace and core objectives such as protecting civilians. Could missions better meet their mandate with improved energy options and reduced emissions, or is there a trade-off with the core objectives? As the missions are nearly fully dependent on diesel generators to power their operations, what is the UN’s responsibility to reduce emissions at a time when addressing climate change is a priority of the UN Secretary-General? Is there an ethical case to make for the UN to support greater use of renewable energy where it operates? And could the UN partner with host nations and others to support a shift in energy use that benefits the communities that host peace operations? This essay argues that missions could reduce their emissions and leverage their energy needs to increase security, strengthen ties to local communities, increase energy access, and support the climate goals of host nations. Drawing on case studies in recent peacekeeping missions and the author’s review of UN commitments across mandates, the Sustainable Development Goals, peacebuilding, and climate goals, this essay will address this area of potential innovation that can help build a positive legacy for UN missions and countries emerging from conflict.

The Sidi Zin Archaeological Project aims to bridge understanding of the Acheulean–Middle Stone Age transition in northern Tunisia, a relatively understudied region in the context of hominin evolution. The Sidi Zin locality will provide chronological, palaeoenvironmental, geomorphological and cultural insights into Acheulean and Middle Stone Age occupations in Tunisia.

Understanding transitions from psychopathology to well-being is crucial for promoting recovery. Plasticity – the ability to modify brain functioning and mental states – is increasingly recognized as essential because it enables the reorganization of neural and mental processes underlying such transitions. Recently, a network-based approach that operationalizes plasticity, and the ability to transition to well-being, as the inverse of the connectivity strength within the symptom network has been proven effective in predicting both the likelihood and timing of recovery from major depressive disorder. This innovative method to measure plasticity is opening new avenues for timely diagnosis, patient stratification, and targeted, individualized treatment of mental illness. Overall, integrating the assessment of plasticity levels into precision psychiatry holds significant potential for developing novel and effective personalized therapeutic strategies in psychiatry.

This article applies van Gennep’s structure of the ritual to the patent application process, arguing that information undergoes several ontological transformations on the way to patentability. The second half of the article applies Turner’s focus on the liminal space. From this perspective, the ‘pure possibility’ of the liminal space is essential to patent law, because it helps negotiate between strong boundaries (as a form of property) and the almost improvisational way in which general rules are applied to specific patents. Taken together, these two approaches provide a more nuanced understanding of how patent law comes into existence and how the patents themselves operate as distinct social and cultural artefacts. The analysis does not intend to replace the economic understanding of patent law, but instead seeks to reflect more completely how it actually functions.
