Resuscitative Endovascular Balloon Occlusion of the Aorta (REBOA) enables temporary haemorrhage control and physiological stabilisation. This article describes the bespoke Defence Medical Services (DMS) training package for effectively using REBOA. The article covers how the course was designed, how the key learning objectives are taught, participant feedback and the authors’ perceptions of future training challenges and opportunities. Since the inaugural training course in April 2019, the authors have delivered six courses, training over 100 clinicians. For the first time in the UK DMS, we designed and delivered a robust specialist endovascular training programme, with demonstrable, significant increases in confidence and competence. As a result of this course, the first DMS REBOA-equipped forward surgical teams deployed in June 2019. Looking to the future, there is a requirement to develop an assessment of skill retention and the potential need for revalidation.

Within the diverse population of working women, those who experience pregnancy for the first time may face some particular challenges when it comes to their career development needs and issues. These include discrimination in the workplace, responding to social expectations and pressures, negotiating life roles, and evolving personal identities. This article discusses the major career problems encountered by this target group, both structurally and socially, with a focus on individual strategies to access personal agentic functioning and empower women facing these challenges. These workers are often overlooked in the career literature; yet, there is a range of career theories to draw upon to assist them in their needs. The application of the life-span, life-space career theory, and the narrative therapy approaches are explored in relation to the helping process. These two theoretical orientations were chosen as they address the particular challenges faced by pregnant women in the workplace, especially around negotiating life roles and an evolving personal identity. There is a need for a stronger understanding of these challenges and opportunities to support pregnant women as they seek vocational wellbeing, and how to tailor suitable, well-established career counselling strategies to meet their unique needs.

Semiconductor nanowires (NWs) represent a unique system for exploring phenomena at the nanoscale and are expected to play a critical role in future electronic, optoelectronic, and miniaturized biomedical devices. Modulation of the composition and geometry of nanostructures during growth could encode information or function, and realize novel applications beyond the conventional lithographical limits. This review focuses on the fundamental science aspects of the bottom-up paradigm, which are synthesis and physical property characterization of semiconductor NWs and NW heterostructures, as well as proof-of-concept device concept demonstrations, including solar energy conversion and intracellular probes. A new NW materials synthesis is discussed and, in particular, a new “nano-tectonic” approach is introduced that provides iterative control over the NW nucleation and growth for constructing 2D kinked NW superstructures. The use of radial and axial p-type/intrinsic/n-type (p-i-n) silicon NW (Si-NW) building blocks for solar cells and nanoscale power source applications is then discussed. The critical benefits of such structures and recent results are described and critically analyzed, together with some of the diverse challenges and opportunities in the near future. Finally, results are presented on several new directions, which have recently been exploited in interfacing biological systems with NW devices.

First Time

Classical composers seeking to create an American sound enjoyed unprecedented success during the 1930s and 1940s. Aaron Copland, Roy Harris, Howard Hanson, and others brought national and international attention to American composers for the first time in history. In the years after World War II, however, something changed. The prestige of musical Americanism waned rapidly as anti-Communists made accusations against leading Americanist composers. Meanwhile, a method of harmonic organization that some considered more Cold War–appropriate—serialism—began to rise in status. For many composers and historians, the Cold War had effectively “killed off” musical Americanism. In this book, the author offers a fuller, more nuanced picture of the effect of the Cold War on Americanist composers. She shows that the ideological conflict brought both challenges and opportunities. Some leftist Americanist composers struggled greatly in this new artistic and political environment, especially as American nationalism increasingly meant American exceptionalism. But composers of all political stripes would find in the federal government a new and unique channel through which to ensure the survival of musical Americanism, as the White House sought to use American music as a Cold War propaganda tool and American composers as cultural diplomats. The Americanists’ efforts to safeguard the reputation of their style would have significant consequences. Ultimately, they effected a rebranding of musical Americanism, with consequences that remain with us today.

Midwives from the Middle East and North African (MENA) region convened in Dubai, United Arab Emirates in 2012 to engage for the first time ever in a discussion concerning regional strategic interventions to strengthen midwifery and the work of midwives in the Arab countries. The workshop was an opportunity to establish a culture of positive and balanced collaboration and mutual understanding among midwives and between midwives and other maternity care professionals including nurses and obstetricians. Key challenges and opportunities in midwifery in the MENA region were identified. Participants agreed on strategic goals to strengthening midwifery education, regulation, and associations in the MENA region.
