'dis ɔhord' : one woman’s experience of confronting and understanding the lived experience of birth.

This paper is a collaborative piece written by a midwifery academic and an artist. It presents and interprets a number of mixed media art works created by Caroline Calonder in response to the traumatic birth of her son, and utilises findings derived from Lesley Kay’s doctoral study about birth and birth stories as a means of contextualising, understanding and interpreting the work (Kay et al 2017). In sharing elements of Caroline’s experience, the psychological harm it caused her, and the means she used (and continues to use) to understand, and come to terms with the experience, the paper highlights some of the distressing and harmful sequelae which can arise when a woman’s disembodied experience of birth is accepted as normal and mainstream. Furthermore, it emphasises the need for health care professionals to actively work towards safeguarding women’s emotional health, and the value of art as a means of confronting and recovering from birth trauma

Exchanging ideas and good practice globally: reciprocal learning in the context of a twinning project

Between August and November 2019, I had the pleasure of making two trips to Bangladesh to support the Royal College of Midwives’ (RCM) twinning project with the Bangladesh Midwifery Society (BMS). The partnership between the RCM and the BMS aims to strengthen the BMS to advocate for the midwifery profession and to create demand for midwifery services. The project is part of a wider programme of midwifery strengthening activities, managed by the United Nations Population Fund (UNFPA) Bangladesh, and funded by donors, the Department for International Development (DFID) and the Swedish International Development Cooperation Agency (Sida)

Using a smartphone app to identify signs of pre-eclampsia and/or worsening blood pressure

Background Hypertensive disorders of pregnancy complicate 10% of pregnancies and can have serious consequences. Aims To explore the experiences of pregnant women with a history of hypertension using an innovative home blood pressure monitoring device. Methods A qualitative study using a grounded theory approach was undertaken. Data were collected through semi-structured interviews. Women were given a blood pressure machine to monitor their blood pressure daily. They inserted their blood pressure results on a smartphone app and answered questions for signs of pre-eclampsia. Participants were followed up every 2 weeks. Findings The results suggested that women wanted a holistic care pathway for the management of hypertension in pregnancy. Three subcategories (‘empowerment’, ‘comparison of care pathways’ and ‘continuity of care’) were also identified. Conclusions The traditional management of hypertension in pregnancy is not holistic. The home blood pressure service was accepted by women and incorporated elements of holistic care but more is required to meet the standard of care that women need

Study of meshing of beveled gears with normally decreasing arc teeth

The meshing of beveled gears was studied by the direct and inverse approaches. Gear wheels with teeth of equal height are studied, and wheels with normally-decreasing arc teeth. Different coordinate systems are utilized to plot the determination of the rotation of the originating gear wheel and the meshing line of the gear wheel which is cut. Matrices are used to determine the equations of the originating surfaces and the unit vectors of the normals to these originating surfaces

Initial experimental evidence that the ability to choose between items alters attraction to familiar versus novel persons in different ways for men and women

Nonhuman species may respond to novel mates with increased sexual motivation (‘The Coolidge Effect1). In humans, novel technological advances, such as online dating platforms, are thought to result in ‘Choice Overload’2. This may undermine the goal of finding a meaningful relationship3, orienting the user toward novel possible partners versus committing to a partner. Here, we used a paradigm measuring change in attraction to familiar faces (i.e. rated on second viewing4) to investigate Coolidge-like phenomena in humans primed with choice of potential online dating partners. We examined two pre-registered hypotheses (https://osf.io/xs74r/files/). First, whether experimentally priming choice (viewing a slideshow of online dating images) directly reduces the attractiveness of familiar preferred sex faces compared to our control condition. Second, whether the predicted effect is stronger for men than women given the role of the Coolidge effect in male sexual motivation5.<br/

The baseline intracluster entropy profile from gravitational structure formation

The radial entropy profile of the hot gas in clusters of galaxies tends to follow a power law in radius outside of the cluster core. Here we present a simple formula giving both the normalization and slope for the power-law entropy profiles of clusters that form in the absence of non-gravitational processes such as radiative cooling and subsequent feedback. It is based on seventy-one clusters drawn from four separate cosmological simulations, two using smoothed-particle hydrodynamics (SPH) and two using adaptive-mesh refinement (AMR), and can be used as a baseline for assessing the impact of non-gravitational processes on the intracluster medium outside of cluster cores. All the simulations produce clusters with self-similar structure in which the normalization of the entropy profile scales linearly with cluster temperature, and these profiles are in excellent agreement outside of 0.2 r_200. Because the observed entropy profiles of clusters do not scale linearly with temperature, our models confirm that non-gravitational processes are necessary to break the self-similarity seen in the simulations. However, the core entropy levels found by the two codes used here significantly differ, with the AMR code producing nearly twice as much entropy at the centre of a cluster.Comment: Accepted to MNRAS, 8 pages, 9 figure

A Hidden Broad-Line Region in the Weak Seyfert 2 Galaxy NGC 788

We have detected a broad H alpha emission line in the polarized flux spectrum of the Seyfert 2 galaxy NGC 788, indicating that it contains an obscured Seyfert 1 nucleus. While such features have been observed in ~15 other Seyfert 2s, this example is unusual because it has a higher fraction of galaxy starlight in its spectrum, a lower average measured polarization, and a significantly lower radio luminosity than other hidden Seyfert 1s discovered to date. This demonstrates that polarized broad-line regions can be detected in relatively weak classical Seyfert 2s, and illustrates why well-defined, reasonably complete spectropolarimetric surveys at H alpha are necessary in order to assess whether or not all Seyfert 2s are obscured Seyfert 1s.Comment: 10 pages using (AASTEX) aaspp4.sty and 4 postscript figures.

When Gender Meets Sex: An Exploratory Study of Women Who Seduce Adolescent Boys

This article describes the origins, design, and implications of a new study exploring female-perpetrated statutory rape against adolescent boys in the United States. In contrast to both legal frameworks, which typically regard statutory rape as a male-on-female phenomenon, and existing literature from the fields of psychology and psychiatry derived from clinical samples and sex offender registries, this study examines the incidence of female-perpetrated statutory rape using data from electronic news reports covering the period 1990-2008. In this short article, the author explains the advantages of her approach over those taken by prior scholars, in terms of the size of the data set and the scope of coverage, as well as her decision to focus on statutory rape exclusively, rather than on female sex abuse more generally. The article also discusses the projected implications of the study for understanding not only the crime of statutory rape, but also the gender assumptions implicit in conventional works on this topic

Brick Walls and AdS/CFT

We discuss the relationship between the bulk-boundary correspondence in Rehren's algebraic holography (and in other 'fixed-background' approaches to holography) and in mainstream 'Maldacena AdS/CFT'. Especially, we contrast the understanding of black-hole entropy from the viewpoint of QFT in curved spacetime -- in the framework of 't Hooft's 'brick wall' model -- with the understanding based on Maldacena AdS/CFT. We show that the brick-wall modification of a Klein Gordon field in the Hartle-Hawking-Israel state on 1+2-Schwarzschild AdS (BTZ) has a well-defined boundary limit with the same temperature and entropy as the brick-wall-modified bulk theory. One of our main purposes is to point out a close connection, for general AdS/CFT situations, between the puzzle raised by Arnsdorf and Smolin regarding the relationship between Rehren's algebraic holography and mainstream AdS/CFT and the puzzle embodied in the 'correspondence principle' proposed by Mukohyama and Israel in their work on the brick-wall approach to black hole entropy. Working on the assumption that similar results will hold for bulk QFT other than the Klein Gordon field and for Schwarzschild AdS in other dimensions, and recalling the first author's proposed resolution to the Mukohyama-Israel puzzle based on his 'matter-gravity entanglement hypothesis', we argue that, in Maldacena AdS/CFT, the algebra of the boundary CFT is isomorphic only to a proper subalgebra of the bulk algebra, albeit (at non-zero temperature) the (GNS) Hilbert spaces of bulk and boundary theories are still the 'same' -- the total bulk state being pure, while the boundary state is mixed (thermal). We also argue from the finiteness of its boundary (and hence, on our assumptions, also bulk) entropy at finite temperature, that the Rehren dual of the Maldacena boundary CFT cannot itself be a QFT and must, instead, presumably be something like a string theory.Comment: 54 pages, 3 figures.
