External Cephalic Version.
Shanahan MM, Gray CJ. Shanahan MM, et al. 2021 Nov 19. In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2022 Jan–. 2021 Nov 19. In: StatPearls [Internet]. Treasure Island (FL): StatPearls Publishing; 2022 Jan–. PMID: 29494082 Free Books & Documents.
It is held that the overall cesarean delivery rate is higher than it should be, and efforts to prevent the first cesarean section often present obstetricians with the task of decreasing the number of cesarean deliveries they perform. One alternative to cesarean delivery is an …

Reconceptualising the external validity of discrete choice experiments.
Lancsar E, Swait J. Lancsar E, et al. Pharmacoeconomics. 2014 Oct;32(10):951-65. doi: 10.1007/s40273-014-0181-7. Pharmacoeconomics. 2014. PMID: 24920196 Review.
While an important component, we argue that the investigation of external validity should be much broader than a comparison of final outcomes. In doing so, we introduce a new and more comprehensive conceptualisation of external validity, closely linked to process va …

Particle Manipulation with External Field; From Recent Advancement to Perspectives.
Miyagawa A, Okada T. Miyagawa A, et al. Anal Sci. 2021 Jan 10;37(1):69-78. doi: 10.2116/analsci.20SAR03. Epub 2020 Sep 11. Anal Sci. 2021. PMID: 32921654 Free article.
Microparticles, including polymer particles, liquid droplets, and biological cells, can be trapped at a particular position and are also transported to arbitrary locations in an appropriate external physical field. Since the force can be externally controlled by the …

Stakeholders External Evaluation of the Clinical Nurse Transition Program.
Seimetz JA. Seimetz JA. J Nurses Prof Dev. 2019 May/Jun;35(3):E6-E10. doi: 10.1097/NND.0000000000000535. J Nurses Prof Dev. 2019. PMID: 30865006
Nurse transition programs have predominantly used internal evaluations to evaluate quality outcomes, and thus, there appears to be a lack of current literature on external evaluation of these programs. External evaluation provides an objective and valuable tool for …
