The experience of vasa praevia for Australian midwives: A qualitative study
© 2018 Australian College of Midwives Background: Vasa praevia can cause stillbirth or early neonatal death if it is not diagnosed antenatally and managed appropriately. Experiencing undiagnosed vasa praevia during labour is challenging and traumatic for women and their care providers. Little is known about the experiences of midwives who care for these women. Aim: To investigate the experience of Australian midwives caring for women with undiagnosed vasa praevia during labour and birth. Methods: A qualitative descriptive study was conducted with midwives in Australia who had cared for at least one woman with vasa praevia during 2010–2016. Semi-structured in-depth telephone interviews were conducted and analysed using thematic analysis. Findings: Twelve of the 20 midwives interviewed were involved in a neonatal death and/or near-miss due to vasa praevia. There was one over-arching theme, which described the ‘devastating and dreadful experience’ for the midwives. This had two inter-related categories of feeling the personal impacts and addressing the professional processes. Feeling scared, shocked, and guilty described how the experience took its toll on the midwives personally. The professional processes included working in organised chaos; feeling for the parents; finding communication to be hard; and, doing their best to save the baby. Discussion: Caring for women who experienced ruptured vasa praevia had a profound impact on the emotional and professional well-being of midwives even when the baby survived. Conclusion: Ruptured vasa praevia was recognised as a traumatic experience that warrants serious considerations from maternity care providers, managers and policy makers. Midwives should be supported and adequately prepared to cope with traumatic events
“I'm a Referee, Not a Female Referee”: The Experiences of Women Involved in Football as Coaches and Referees
The development of the Women's Super League (WSL) in English football, increased media coverage of the game, and an expansion of grassroots opportunities indicate a bright future for women and girls who want to play. Yet this vision must be tempered against compelling evidence of deep rooted and enduring gender inequalities within the game. This is the case for both players, and women who undertake non-playing roles, which is reflected in the relatively low numbers of women coaches and referees. Whilst The Football Association (The FA) has signalled addressing these inequalities as a key priority, critics argue that such efforts amount to superficial and limited efforts to support meaningful change. This paper departs from a concern with playing the game and responds to calls for more research to explore the experiences of women involved in football in non-playing roles. More specifically, it focuses on women coaches and referees, and addresses the following question: how do women in positions of power in football negotiate their place in what remains a distinctly male-dominated profession? In addressing this question, we take a theoretical position located at the nexus between radical and post-structural feminism, acknowledging the significance of structural power relations and individual agency in shaping daily lived social realities. Data were generated from interviews with 14 women coaches and 10 women referees. These interviews explored the structure and culture of the game and its impact on women's experiences of men's and women's competitive and grassroots football. Through a rigorous process of thematic analysis, three themes were identified: gendered entry into football careers; reinforcement of women's difference on the football field; and coping strategies for remaining in the game. Centralising the women's voices in this research highlights the insidious and persistent nature of gendered microaggressions, the sexism of football culture, and the ways in which these women negotiate this masculine terrain in their pursuit of being coaches and referees.

The trigger system of the NOMAD experiment
The NOMAD trigger system is described in the present paper. It is made up of a largearea plastic scintillator veto system, two trigger scintillator planes inside a 0.4~Tmagnetic field and their associated trigger electronics. Special features of the systemconsist of the use of proximity mesh photomultipliers which allow the trigger scintillators to operate in the magnetic field, and the use of custom-built VME moduleswhich perform the trigger logic decisions, the signal synchronisation and gate generation,event counting and livetime calculations. This paper also includes a description of each of the NOMAD triggers, with their calculated and measured rates, efficiencies and livetimes
Production properties of K*(892) vector mesons and their spin alignment as measured in the NOMAD experiment
First measurements of K*(892) mesons production properties and their spin
alignment in nu_mu charged current (CC) and neutral current (NC) interactions
are presented. The analysis of the full data sample of the NOMAD experiment is
performed in different kinematic regions. For K*+ and K*- mesons produced in
nu_mu CC interactions and decaying into K0 pi+/- we have found the following
yields per event: (2.6 +/- 0.2 (stat.) +/- 0.2 (syst.))% and (1.6 +/- 0.1
(stat.) +/- 0.1 (syst.))% respectively, while for the K*+ and K*- mesons
produced in nu NC interactions the corresponding yields per event are: (2.5 +/-
0.3 (stat.) +/- 0.3 (syst.))% and (1.0 +/- 0.3 (stat.) +/- 0.2 (syst.))%. The
results obtained for the rho00 parameter, 0.40 +/- 0.06 (stat) +/- 0.03 (syst)
and 0.28 +/- 0.07 (stat) +/- 0.03 (syst) for K*+ and K*- produced in nu_mu CC
interactions, are compared to theoretical predictions tuned on LEP measurements
in e+e- annihilation at the Z0 pole. For K*+ mesons produced in nu NC
interactions the measured rho00 parameter is 0.66 +/- 0.10 (stat) +/- 0.05
(syst).Comment: 20 p
Circulating syndecan-1 is reduced in pregnancies with poor fetal growth and its secretion regulated by matrix metalloproteinases and the mitochondria
Fetal growth restriction is a leading cause of stillbirth that often remains undetected during pregnancy. Identifying novel biomarkers may improve detection of pregnancies at risk. This study aimed to assess syndecan-1 as a biomarker for small for gestational age (SGA) or fetal growth restricted (FGR) pregnancies and determine its molecular regulation. Circulating maternal syndecan-1 was measured in several cohorts; a large prospective cohort collected around 36 weeks' gestation (n = 1206), a case control study from the Manchester Antenatal Vascular service (285 women sampled at 24-34 weeks' gestation); two prospective cohorts collected on the day of delivery (36 + 3-41 + 3 weeks' gestation, n = 562 and n = 405 respectively) and a cohort who delivered for preterm FGR (< 34 weeks). Circulating syndecan-1 was consistently reduced in women destined to deliver growth restricted infants and those delivering for preterm disease. Syndecan-1 secretion was reduced by hypoxia, and its loss impaired proliferation. Matrix metalloproteinases and mitochondrial electron transport chain inhibitors significantly reduced syndecan-1 secretion, an effect that was rescued by coadministration of succinate, a mitochondrial electron transport chain activator. In conclusion, circulating syndecan-1 is reduced among cases of term and preterm growth restriction and has potential for inclusion in multi-marker algorithms to improve detection of poorly grown fetuses
Search for the exotic resonance in the NOMAD experiment
A search for exotic Theta baryon via Theta -> proton +Ks decay mode in the
NOMAD muon neutrino DIS data is reported. The special background generation
procedure was developed. The proton identification criteria are tuned to
maximize the sensitivity to the Theta signal as a function of xF which allows
to study the Theta production mechanism. We do not observe any evidence for the
Theta state in the NOMAD data. We provide an upper limit on Theta production
rate at 90% CL as 2.13 per 1000 of neutrino interactions.Comment: Accepted to European Physics Journal
Search for nu(mu)-->nu(e) Oscillations in the NOMAD Experiment
We present the results of a search for nu(mu)-->nu(e) oscillations in the
NOMAD experiment at CERN. The experiment looked for the appearance of nu(e) in
a predominantly nu(mu) wide-band neutrino beam at the CERN SPS. No evidence for
oscillations was found. The 90% confidence limits obtained are delta m^2 < 0.4
eV^2 for maximal mixing and sin^2(2theta) < 1.4x10^{-3} for large delta m^2.
This result excludes the LSND allowed region of oscillation parameters with
delta m^2 > 10 eV^2.Comment: 19 pages, 8 figures. Submitted to Phys. Lett.
A Study of Strange Particles Produced in Neutrino Neutral Current Interactions in the NOMAD Experiment
Results of a detailed study of strange particle production in neutrino
neutral current interactions are presented using the data from the NOMAD
experiment. Integral yields of neutral strange particles (K0s, Lambda,
Lambda-bar) have been measured. Decays of resonances and heavy hyperons with an
identified K0s or Lambda in the final state have been analyzed. Clear signals
corresponding to K* and Sigma(1385) have been observed. First results on the
measurements of the Lambda polarization in neutral current interactions have
been obtained.Comment: Accepted for publication in Nuclear Physics B as a rapid

A Precise Measurement of the Muon Neutrino-Nucleon Inclusive Charged Current Cross-Section off an Isoscalar Target in the Energy Range 2.5 < E_\nu < 40 GeV by NOMAD
We present a measurement of the muon neutrino-nucleon inclusive charged
current cross-section, off an isoscalar target, in the neutrino energy range
GeV. The significance of this measurement is its
precision, % in GeV, and % in GeV regions, where significant uncertainties in previous
experiments still exist, and its importance to the current and proposed long
baseline neutrino oscillation experiments.Comment: 14 pages, 3 figures, submitted to Phys.Lett.
A Measurement of Coherent Neutral Pion Production in Neutrino Neutral Current Interactions in NOMAD
We present a study of exclusive neutral pion production in neutrino-nucleus
Neutral Current interactions using data from the NOMAD experiment at the CERN
SPS. The data correspond to muon-neutrino Charged Current
interactions in the energy range GeV. Neutrino
events with only one visible in the final state are expected to result
from two Neutral Current processes: coherent production, {\boldmath
} and single production in
neutrino-nucleon scattering. The signature of coherent production is an
emergent almost collinear with the incident neutrino while 's
produced in neutrino-nucleon deep inelastic scattering have larger transverse
momenta. In this analysis all relevant backgrounds to the coherent
production signal are measured using data themselves. Having determined the
backgrounds, and using the Rein-Sehgal model for the coherent
production to compute the detection efficiency, we obtain {\boldmath } corrected coherent- events with GeV. We measure {\boldmath }.
This is the most precise measurement of the coherent production to
date.Comment: 23 pages, 9 figures, accepted for publication in Phys. Lett.
