    Background: Alongside midwifery units (AMUs) are managed by midwives and proximate to obstetric units (OUs), offering a home-like birth environment for women with straightforward pregnancies. They support physiological birth, with fast access to medical care if needed. AMUs have good perinatal outcomes and lower rates of interventions than OUs. In England, uptake remains lower than potential use, despite recent changes in policy to support their use. This article reports on experiences of access from a broader study that investigated AMU organisation and care. Methods: Organisational case studies in four National Health Service (NHS) Trusts in England, selected for variation geographically and in features of their midwifery units. Fieldwork (December 2011 to October 2012) included observations (>100 h); semi-structured interviews with staff, managers and stakeholders (n = 89) and with postnatal women and partners (n = 47), on which this paper reports. Data were analysed thematically using NVivo10 software. Results: Women, partners and families felt welcome and valued in the AMU. They were drawn to the AMUs’ environment, philosophy and approach to technology, including pain management. Access for some was hindered by inconsistent information about the existence, environment and safety of AMUs, and barriers to admission in early labour. Conclusions:Key barriers to AMUs arise through inequitable information and challenges with admission in early labour. Most women still give birth in obstetric units and despite increases in the numbers of women birthing on AMUs since 2010, addressing these barriers will be essential to future scale-up

    Fluctuating-friction molecular motors

    We show that the correlated stochastic fluctuation of the friction coefficient can give rise to long-range directional motion of a particle undergoing Brownian random walk in a constant periodic energy potential landscape. The occurrence of this motion requires the presence of two additional independent bodies interacting with the particle via friction and via the energy potential, respectively, which can move relative to each other. Such three-body system generalizes the classical Brownian ratchet mechanism, which requires only two interacting bodies. In particular, we describe a simple two-level model of fluctuating-friction molecular motor that can be solved analytically. In our previous work [M.K., L.M and D.P. 2000 J. Nonlinear Opt. Phys. Mater. vol. 9, 157] this model has been first applied to understanding the fundamental mechanism of the photoinduced reorientation of dye-doped liquid crystals. Applications of the same idea to other fields such as molecular biology and nanotechnology can however be envisioned. As an example, in this paper we work out a model of the actomyosin system based on the fluctuating-friction mechanism.Comment: to be published in J.

    Richard Lance Keeble argues that Fleet Street’s coverage of the Afghan conflict has served largely to promote the interests of the military/industrial/media complex – and marginalise the views of the public who have consistently appealed in polls for the troops to be brought back hom
