A losing battle? Women's sport pre- and post-COVID-19
Research question: In 2019, women's sport was reported as being on the rise. Increased participation rates, media coverage, investment and support were evident. Following the spread of COVID-19 across the globe, which halted most forms of competitive sport, there were repeated concerns about the future of women’s sport. This research aims to document elite sportswomen’s perceptions of the state of women's sport pre-COVID-19 and the possible impact moving forwards.
Research methods: Ninety five responses from an online, anonymous, qualitative questionnaire completed by elite sportswomen mainly based, in the UK, on the impact of COVID-19 on women's sport were collected. Data were subject to a thematic analysis, to determine key concerns, and the frequency data of responses were quantitatively recorded.
Results and findings: Most sportswomen felt that women’s sport was on an upward trajectory, but many juxtaposed that against inequality compared to men's sport in terms of media coverage and finance. There were concerns that the subordinate position women's sport, with less resources and support, will have severe implications post-COVID-19. However, there were considerations that a pause in sport would allow for personal development, increased participation upon sports return and space for a reconfiguration of sport.
Implications: Those involved in sport are encouraged to think more critically about progress narratives in women's sport. We caution that these hide perpetual, structural and symbolic inequalities and propose that they are positioned more coherently within wider gender equity agenda. This is a process that will require widespread cultural change
On the Use of 'Glyphmaps' for Analysing the Scale and Temporal Spread of COVID-19 Reported Cases
Recent analysis of area-level COVID-19 cases data attempts to grapple with a challenge familiar to geovisualization: how to capture the development of the virus, whilst supporting analysis across geographic areas? We present several glyphmap designs for addressing this challenge applied to local authority data in England whereby charts displaying multiple aspects related to the pandemic are given a geographic arrangement. These graphics are visually complex, with clutter, occlusion and salience bias an inevitable consequence. We develop a framework for describing and validating the graphics against data and design requirements. Together with an observational data analysis, this framework is used to evaluate our designs, relating them to particular data analysis needs based on the usefulness of the structure they expose. Our designs, documented in an accompanying code repository, attend to common difficulties in geovisualization design and could transfer to contexts outside of the UK and to phenomena beyond the pandemic

The gendered effects of COVID-19 on elite women's sport
The coronavirus (Covid-19) pandemic in early 2020 prompted widespread global lockdowns as the world looked to contain and reduce the impact of the virus, including a pause on most sporting competitions (Parnell et al., 2020). Covid-19 has greatly affected the world, exposing stark inequalities, especially across gendered lines, in areas of society such as the labour market, domestic responsibility, and economic hardship (Alon et al., 2020). Sport is a crucial, interwoven aspect of society and like wider societal trends, elite women’s sport has been adversely affected by the pandemic, facing an existential threat (Bowes et al., 2020; Clarkson et al., 2020a; Rowe, 2020). The aim of this chapter is to provide an overview of how the pandemic is negatively impacting a wide variety of elite women’s sports. Specifically, we cover sports where women have traditionally existed on the margins of the sport and could be considered as male-dominated labour industries. Centring primarily on the United Kingdom (UK), we present a brief chronology of the impact of the crisis on elite women’s sport, across football, rugby, cricket and golf - in many ways different to the men’s versions - spanning the eight months since the start of the pandemic in March 2020 until the time of writing in November 2020. Throughout, the chapter utilises qualitative data from elite sportswomen encouraged to share their experiences during the pandemic (see Bowes et al., 2020). Subsequently, this chapter concludes with a summary of the challenges for women operating in (semi-)professional sports environments
A Coordinated X-ray and Optical Campaign of the Nearby Massive Binary Orionis Aa: II. X-ray Variability
We present time-resolved and phase-resolved variability studies of an
extensive X-ray high-resolution spectral dataset of the Orionis Aa
binary system. The four observations, obtained with Chandra ACIS HETGS, have a
total exposure time of ~479 ks and provide nearly complete binary phase
coverage. Variability of the total X-ray flux in the range 5-25 is
confirmed, with maximum amplitude of about +/-15% within a single ~125 ks
observation. Periods of 4.76d and 2.04d are found in the total X-ray flux, as
well as an apparent overall increase in flux level throughout the 9-day
observational campaign. Using 40 ks contiguous spectra derived from the
original observations, we investigate variability of emission line parameters
and ratios. Several emission lines are shown to be variable, including S XV, Si
XIII, and Ne IX. For the first time, variations of the X-ray emission line
widths as a function of the binary phase are found in a binary system, with the
smallest widths at phase=0.0 when the secondary Orionis Aa2 is at
inferior conjunction. Using 3D hydrodynamic modeling of the interacting winds,
we relate the emission line width variability to the presence of a wind cavity
created by a wind-wind collision, which is effectively void of embedded wind
shocks and is carved out of the X-ray-producing primary wind, thus producing
phase-locked X-ray variability.Comment: 36 pages, 14 Tables, 19 Figures, accepted by ApJ, one of 4 related

A Coordinated X-ray and Optical Campaign on the Nearest Massive Eclipsing Binary, Delta Ori Aa: I. Overview of the X-ray Spectrum
We present an overview of four phase-constrained Chandra HETGS X-ray
observations of Delta Ori A. Delta Ori A is actually a triple system which
includes the nearest massive eclipsing spectroscopic binary, Delta Ori Aa, the
only such object which can be observed with little phase-smearing with the
Chandra gratings. Since the fainter star, Delta Ori Aa2, has a much lower X-ray
luminosity than the brighter primary, Delta Ori A provides a unique system with
which to test the spatial distribution of the X-ray emitting gas around Delta
Ori Aa1 via occultation by the photosphere of and wind cavity around the X-ray
dark secondary. Here we discuss the X-ray spectrum and X-ray line profiles for
the combined observation, having an exposure time of nearly 500 ksec and
covering nearly the entire binary orbit. Companion papers discuss the X-ray
variability seen in the Chandra spectra, present new space-based photometry and
ground-based radial velocities simultaneous with the X-ray data to better
constrain the system parameters, and model the effects of X-rays on the optical
and UV spectrum. We find that the X-ray emission is dominated by embedded wind
shock emission from star Aa1, with little contribution from the tertiary star
Ab or the shocked gas produced by the collision of the wind of Aa1 against the
surface of Aa2. We find a similar temperature distribution to previous X-ray
spectrum analyses. We also show that the line half-widths are about
the terminal velocity of the wind of star Aa1. We find a strong
anti-correlation between line widths and the line excitation energy, which
suggests that longer-wavelength, lower-temperature lines form farther out in
the wind. Our analysis also indicates that the ratio of the intensities of the
strong and weak lines of \ion{Fe}{17} and \ion{Ne}{10} are inconsistent with
model predictions, which may be an effect of resonance scatteringComment: accepted by ApJ; revised according to ApJ proo
Diverting phenylpropanoid pathway flux from sinapine to produce industrially useful 4-vinyl derivatives of hydroxycinnamic acids in Brassicaceous oilseeds
Sinapine (sinapoylcholine) is an antinutritive phenolic compound that can account for up to 2% of seed weight in brassicaceous oilseed crops and reduces the suitability of their protein-rich seed meal for use as animal feed. Sinapine biosynthesis draws on hydroxycinnamic acid precursors produced by the phenylpropanoid pathway. The 4-vinyl derivatives of several hydroxycinnamic acids have industrial applications. For example, 4-vinyl phenol (4-hydroxystyrene) is a building block for a range of synthetic polymers applied in resins, inks, elastomers, and coatings. Here we have expressed a modified bacterial phenolic acid decarboxylase (PAD) in developing seed of Camelina sativa to redirect phenylpropanoid pathway flux from sinapine biosynthesis to the production of 4-vinyl phenols. PAD expression led to a ∼95% reduction in sinapine content in seeds of both glasshouse and field grown C. sativa and to an accumulation of 4-vinyl derivatives of hydroxycinnamic acids, primarily as glycosides. The most prevalent aglycone was 4-vinyl phenol, but 4-vinyl guaiacol, 6-hydroxy-4-vinyl guaiacol and 4-vinylsyringol (Canolol) were also detected. The molar quantity of 4-vinyl phenol glycosides was more than twice that of sinapine in wild type seeds. PAD expression was not associated with an adverse effect on seed yield, harvest index, seed morphology, storage oil content or germination in either glasshouse or field experiments. Our data show that expression of PAD in brassicaceous oilseeds can supress sinapine accumulation, diverting phenylpropanoid pathway flux into 4-vinyl phenol derivatives, thereby also providing a non-petrochemical source of this class of industrial chemicals
