This invited paper describes prototype SiC JFET integrated circuit (IC) and packaging technology that has produced arguably the most harsh-environment durable electronics ever demonstrated. Prototype medium-scale integration (MSI) ICs fabricated by NASA Glenn Research Center have successfully operated for over 1 year in 500 °C air-ambient, over 60 days in 460 °C and 9.3 MPa pressure caustic Venus surface environment test chamber, from -190 °C to +812 °C, and radiation exposure through 7 MRad(Si) total ionizing dose and 86 MeV-cm2/mg heavy ion strikes. Recent on-going work focused on upscaling this “go anywhere” IC capability from MSI to large-scale integration (LSI) prototype via benchmark memory ICs is described.

- Abstract
Introduction: A scalpel cricothyroidotomy or front of neck access (FONA) is a rarely performed part of airway management for when other steps have failed and the patient cannot be intubated or ventilated. Increasingly advanced and specialist paramedics are being trained to perform this procedure within the pre-hospital environment., Methods: Advanced and specialist paramedics within a UK ambulance service that had performed a FONA were invited to participate in this qualitative research. Semi-structured interviews were used to gather information on the participants' experiences. This information underwent thematic analysis to develop codes which were then grouped into themes., Results: Seven participants were interviewed between December 2020 and January 2021. Three main themes were identified: the procedure, isolation and training. The main complications described were bleeding in excess of expectations, moving structures, surgical emphysema and a false track., Conclusion: Complications appeared common; training to perform a FONA should include complications and an approach to their management similar to other airway management procedures. Isolation was a common theme within this study, however remote support from a peer appeared beneficial., (© 2022 The Author(s).)

- Abstract
Aim: The aim was to explore the experiences of new graduate nurses who provide support to breastfeeding women in neonatal care settings. The objective of this study was to explore the enablers and barriers that influenced new graduate nurses' self-efficacy., Background: Nurses have important roles in promoting and educating breastfeeding women in neonatal care settings. Although there are many studies that focused on nursing students and registered nurses' experiences in supporting breastfeeding women, there is limited research about the experiences of new graduate nurses during their transition from universities to neonatal care settings as a registered nurse where they learn how to educate and support breastfeeding women., Design: A qualitative descriptive study., Methods: Nine new graduate nurses who support breastfeeding women in neonatal care settings within Australia were recruited. Data was collected through semi-structured interviews via videoconference or telephone. Braun & Clarke's thematic analysis was used to analyse the data., Results: This study found four themes: Preparedness, Emotions, Ongoing Learning, and Confidence. Barriers and enablers included support, time, consistency of information, and impact of stereotyping. The new graduate nurses did not initially feel prepared to support breastfeeding women due to their lack of knowledge. Participants' self-efficacy enhancing strategies to help build knowledge and confidence supporting breastfeeding women included: a) frequent practice, b) having role models and seeking support, c) receiving encouragement and positive feedback, and d) interpreting their emotional feelings as a normal reaction to the learning process., Conclusion: Additional education should be provided during pre-registration education and on commencement of employment in neonatal settings to improve new graduate nurses'knowledge supporting breastfeeding women. Self-efficacy enhancing strategies can be used in partnerships between educational institutions and hospitals to support new graduate nurses to feel more confident providing breastfeeding support in neonatal care settings., (Copyright © 2021 Elsevier Ltd.

- Abstract
Objective: To describe the experiences of registered nurses (RNs) who support breastfeeding women and to understand the factors that they believe affect practices that support breastfeeding., Data Sources: We conducted an online search using five databases: Scopus, MEDLINE, Cumulative Index of Nursing and Allied Health Literature (CINAHL), the Cochrane Database of Systematic Reviews, and Joanna Briggs Institute of Systematic Reviews., Study Selection: We included original research articles on the experiences of RNs who support breastfeeding women that were published in 2009 or after and were available in English. After title and abstract review of 785 articles, we included 22 articles for full text review. Nine articles met the eligibility criteria and were included in the review., Data Extraction: We used Whittemore and Knafl's five-step framework and the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) reporting guidelines to guide this integrative review. Three authors reviewed and appraised the articles independently., Data Synthesis: We categorized the findings into three themes: Workplace Issues, Personal Experiences, and Breastfeeding Knowledge and Education. Workplace Issues included the subthemes Lack of Time and Workload and Infant Health Stability. Personal Experiences included the subthemes Attitudes, Individual Experiences With Breastfeeding, and The Experiences of Family and Friends. Breastfeeding Knowledge and Education included the subthemes Prelicensure Education and Workplace Education and Training. Most researchers identified deficits in knowledge and education among RNs. The concept of confidence was influenced by all the other themes. Participants in the included studies reported that they developed confidence after learning from lactation consultants and having role models who supported the development of their knowledge and skills., Conclusion: Despite the heterogeneity among the studies, findings highlighted the need for an increased focus on the preparation of RNs to support women to effectively breastfeed within health care organizations. Multitargeted efforts, such as orientation programs and in-depth breastfeeding education using role modeling, mentorship, and role playing with practical scenarios, may improve RNs' abilities and confidence to support breastfeeding women., Competing Interests: Conflict of Interest The authors report no conflicts of interest or relevant financial disclosures., (Copyright © 2021 AWHONN, the Association of Women’s Health, Obstetric and Neonatal Nurses.

6. Perils and positives of science journalism in Australia.

- Abstract
Scientists, science communicators and science journalists interact to deliver science news to the public. Yet the value of interactions between the groups in delivering high-quality science stories is poorly understood within Australia. A recent study in New Zealand on the perspectives of the three groups on the challenges facing science journalism is replicated here in the context of New South Wales and the Australian Capital Territory. While all three groups perceived the quality of science journalism as generally high, the limitations of non-specialists and public relation materials were causes for concern. The results indicate that science communicators are considered to play a valuable role as facilitators of information flow to journalists and support for scientists. Future studies on the influence and implications of interactions between these three groups are required.

7. A miniature microcontroller curve tracing circuit for space flight testing transistors.

- Abstract
This paper describes a novel miniature microcontroller based curve tracing circuit, which was designed to monitor the environmental effects on Silicon Carbide Junction Field Effect Transistor (SiC JFET) device performance, while exposed to the low earth orbit environment onboard the International Space Station (ISS) as a resident experiment on the 7th Materials on the International Space Station Experiment (MISSE7). Specifically, the microcontroller circuit was designed to operate autonomously and was flown on the external structure of the ISS for over a year. This curve tracing circuit is capable of measuring current vs. voltage (I-V) characteristics of transistors and diodes. The circuit is current limited for low current devices and is specifically designed to test high temperature, high drain-to-source resistance SiC JFETs. The results of each I-V data set are transmitted serially to an external telemetered communication interface. This paper discusses the circuit architecture, its design, and presents example results.
