Radio Continuum Study of Supernova Remnants in the Large Magellanic Cloud - SNR J0519-6926
We present the results of new high resolution ATCA observations of SNR
J0519-6926. We found that this SNR exhibits a typical "horseshoe" appearance
with alpha = -0.55 +- 0.08 and D=28+-1 pc. No polarization (or magnetic fields)
are detected to a level of 1%. This is probably due to a relatively poor
sampling of the uv plane caused be observing in "snap-shot" mode.Comment: 6 pages 4 figures, to be published in Serbian Astronomical Journa

Radio-Continuum Observations Of Small, Radially Polarised Supernova Remnant J0519-6902 In The Large Magellanic Cloud
We report on new Australian Telescope Compact Array (ATCA) observations of
SNR J0519-6902. The Supernova Remnant (SNR) is small in size (~8 pc) and
exhibits a typical SNR spectrum of alpha = -0.53 +- 0.07, with steeper spectral
indices found towards the northern limb of the remnant. SNR J0519-6902 contains
a low level of radially orientated polarisation at wavelengths of 3 & 6 cm,
which is characteristic of younger SNRs. A fairly strong magnetic field was
estimated of ~171 microG. The remnant appears to be the result of a typical
Type Ia supernovae, sharing many properties as another small and young Type Ia
LMC SNR, J0509-6731.Comment: 10 pages 7 figures, submitted to Serbian Astronomical Journa
The Strongest 100 Point Radio Sources in the LMC at 1.4 GHz
We present the 100 strongest 1.4 GHz point sources from a new mosaic image in
the direction of the Large Magellanic Cloud (LMC). The observations making up
the mosaic were made over a ten year period and were combined with Parkes
single dish data at 1.4 GHz to complete the image for short spacing. An initial
list of co-identifications within 10" at 0.843, 4.8 and 8.6 GHz consisted of
2682 sources. Elimination of extended objects and artifact noise allowed the
creation of a refined list containing 1988 point sources. Most of these are
presumed to be background objects seen through the LMC; a small portion may
represent compact H II regions, young SNRs and radio planetary nebulae. For the
1988 point sources we find a preliminary average spectral index of -0.53 and
present a 1.4 GHz image showing source location in the direction of the LMC.Comment: 8 pages, 2 figure
Radio-continuum study of Large Magellanic Cloud Supernova Remnant J0509-6731
We present a detailed study of Australia Telescope Compact Array (ATCA)
observations ( = 20, 13, 6 & 3~cm) of supernova remnant (SNR)
J0509--6731 in the Large Magellanic Cloud (LMC). The remnant has a ring
morphology with brightened regions towards the south-western limb. We also find
a second brightened inner ring which is only seen in the radio-continuum. The
SNR is almost circular, with a diameter ranging from 7 to 8~pc, and a steep
radio spectral index between 36 and 3~cm of , which is
characteristic of younger SNRs. We also report detection of radially orientated
polarisation across the remnant at 6~cm, with a mean fractional polarisation
level of ~(26~~13)%. We find the magnetic field (168~G)
and ( ~W
m~Hz~sr , 7.35~pc) to be consistent with other young
remnants
Reports on Payments to Governments: A critical review of early developments and experiences
We are concerned to review and discuss aspects of the Reports submitted in line with the Payments to Governments Regulations. We consider the process of transposition of this EU Accounting Law into UK law and the early implementation or operationalization of this law in the UK. Recommendations drawn from the study are intended to be of use to a variety of stakeholders who may input into the upcoming government consultation on these regulations.

Accounting Law in Practice: Compliance, Consistency and Substance Focusing on the UK’s Implementation of EU Extractive Industry Country by Country Reporting of Government Payments to Governments
The passing into EU Law of a requirement that all companies domiciled in member states or listed on EU stock exchanges should publish a Report of Payments to Governments on the face of it is a victory for the civil society organizations long campaigning for the attendant increased transparency and accountability, a step towards better conditions and possibilities for many of the world’s poor. But it cannot be taken for granted. It was passed with a condition that it be reviewed (at both member state level, where a review can feed into the federal level review, and at the level of the EU), which is an opportunity to better it or a threat to reverse positive potentialities. The UK Brexit vote adds some uncertainty regarding the future of the law in the UK. And studies of manifestations of practices such as accounting and auditing (often intersecting with the law) caution against too much optimism as to their straightforward effectiveness. With a view to understanding this particular law in practice, so that it be strengthened and better function in line with its intended aims, we explore processes of its construction and early adoption in the UK. In a preliminary analysis, we elaborate how interpretations of the Law within the Extractives Industry run counter to the spirit or substance of the law and give rise to different and apparently problematic translations of the law into practice. Reflecting on our analysis, we make some recommendations as to ways forward

We consider the process of transposition of this Accounting Law into UK law and the early implementation or operationalization of this law in the UK.

Multifrequency radio observations of SNR J0536-6735 (N 59B) with associated pulsar
We present a study of new Australian Telescope Compact Array (ATCA)
observations of supernova remnant, SNR J0536-6735. This remnant appears to
follow a shell morphology with a diameter of D=36x29 pc (with 1 pc uncertainty
in each direction). There is an embedded Hii region on the northern limb of the
remnant which made various analysis and measurements (such as flux density,
spectral index and polarisation) difficult. The radio-continuum emission
followed the same structure as the optical emission, allowing for extent and
flux density estimates at 20 cm. We estimate a surface brightness for the SNR
at 1 GHz of 2.55x10^-21 W m^-2 Hz^-1 sr^-1. Also, we detect a distinctive
radio-continuum point source which confirms the previous suggestion of this
remnant being associated with a pulsar wind nebulae (PWN). The tail of this
remnant isn't seen in the radio-continuum images and is only seen in the
optical and X-ray images.Comment: 10 pages 4 figures, accepted for publication in SA
The Ground on Which We All Stand: A Conversation About Menstrual Equity Law and Activism
This essay grows out of a panel discussion among five lawyers on the subject of menstrual equity activism. Each of the authors is a scholar, activist or organizer involved in some form of menstrual equity work. The overall project is both enriched and complicated by an intersectional analysis.
This essay increases awareness of existing menstrual equity and menstrual justice work; it also identifies avenues for further inquiry, next steps for legal action, and opportunities that lie ahead. After describing prior and current work at the junction of law and menstruation, the contributors evaluate the successes and limitations of recent legal changes. The authors then turn to conceptual issues about the relationship between menstrual equity and gender justice, as well as the difference between equity and equality. The essay concludes with consideration of the future of menstrual equity and menstrual justice work. The authors envision an expanded, inclusive group of individuals working for greater gender justice
