Climate change was the defining issue in the 2022 Australian federal election. As a new administration takes power, all sectors, including the performing arts, need to keep up the pressure. An iconic moment of “coal theatrics” in Parliament House, so labeled by the Australian media, stands in contrast to artistic performances that continue to put pressure on the framers of political and cultural policy.

An accomplished dancer, acrobat, and physical theatre performer, Hanna Cormick became ill in 2014 with a trifecta of rare genetic conditions that make her severely allergic to pollutants in the air — smoke, detergents, and food particles — and her bones and internal organs prone to dislocation. In January 2020, during Australia’s summer of unprecedented bushfires, Cormick staged The Mermaid, risking her life to make a performance about the climate emergency and how we are all vulnerable bodies at risk in a changing environment.

Healthcare workers (HCWs) not fulfilling the coronavirus disease 2019 (COVID-19) case definition underwent severe acute respiratory coronavirus virus 2 (SARS-CoV-2) screening. Risk of exposure, adherence to personal protective equipment (PPE), and symptoms were assessed. In total, 2,000 HCWs were screened: 5.5% were positive for SARS-CoV-2 by polymerase chain reaction (PCR). There were no differences in PPE use between SARS-CoV-2–positive and –negative HCWs (adherence, >90%). Nursing and kitchen staff were independently associated with positive SARS-CoV-2 results.

From mid-October to mid-November 2013, Australian performance artist Casey Jenkins sat for twenty-eight days in a gallery in Darwin, far North Australia, knitting a scarf from a ball of wool lodged in her vagina. Parts of the performance of Casting Off My Womb were filmed by the public broadcasting service SBS2, and aired in late November 2013 as a two-minute-and-forty-eight-second video clip re-titled Vaginal Knitting. The clip went viral on YouTube, with over seven million views as of March 2016, and received extensive media attention. Casting Off My Womb attracted global public interest because Jenkins continued to knit throughout the days of her period, weaving her menstrual blood into the artwork. The performance elicited strong responses from its global viewing public. While some people praised the work, many online spectators wrote vicious, derisive and personal attacks on Jenkins for displaying her menstrual blood in a public place. This article uses Matthew Goulish's methodology of ‘slow thinking’ as a counterresponse to the impulsive reactions of the online spectators and as a means to register the powerful and incremental energy and effects of Jenkins's feminist performance.

The Integrated Public Use Microdata Series (IPUMS)-International partnership is a project of the Minnesota Population Center and national statistical agencies, dedicated to collecting and distributing census data from around the world. IPUMS is currently disseminating data on over a half-billion persons enumerated in more than 250 census samples from 79 countries. The data series includes information on a broad range of population characteristics, including fertility, nuptiality, life-course transitions, migration, labor-force participation, occupational structure, education, ethnicity, and household composition. This paper describes sample characteristics and data structure; the data integration process including the creation of constructed family interrelationship variables; the flexible dissemination system that enables researchers to build customized extracts of pooled census samples across time and place; and some of the most significant findings that have emerged from the database.

Despite many advances in recent years for patients with critical paediatric and congenital cardiac disease, significant variation in outcomes remains across hospitals. Collaborative quality improvement has enhanced the quality and value of health care across specialties, partly by determining the reasons for variation and targeting strategies to reduce it. Developing an infrastructure for collaborative quality improvement in paediatric cardiac critical care holds promise for developing benchmarks of quality, to reduce preventable mortality and morbidity, optimise the long-term health of patients with critical congenital cardiovascular disease, and reduce unnecessary resource utilisation in the cardiac intensive care unit environment. The Pediatric Cardiac Critical Care Consortium (PC4) has been modelled after successful collaborative quality improvement initiatives, and is positioned to provide the data platform necessary to realise these objectives. We describe the development of PC4 including the philosophical, organisational, and infrastructural components that will facilitate collaborative quality improvement in paediatric cardiac critical care.

The triennial meeting of Commission 4 was attended by 16 people. All of the presentations from the meeting are provided on the commission website at http://www.iaucom4.org/c4docs.html, so this report provides only summaries.

The Commission 4 Organizing Committee began its work for the 2009-2012 triennium by revising the commission's terms of reference, which serve as our “mission statement.” The new terms of reference are:

1. (a) Maintain cooperation and collaboration between the national offices providing ephemerides, prediction of phenomena, astronomical reference data, and navigational almanacs.

2. (b) Encourage agreement on the bases (reference systems, time scales, models, and constants) of astronomical ephemerides and reference data in the various countries. Promote improvements to the usability and accuracy of astronomical ephemerides, and provide information comparing computational methods, models, and results to ensure the accuracy of data provided.

3. (c) Maintain databases, available on the Internet to the national ephemeris offices and qualified researchers, containing observations of all types on which the ephemerides are based. Promote the continued importance of observations needed to improve the ephemerides, and encourage prompt availability of these observations, especially those from space missions, to the science community.

4. (d) Encourage the development of software and web sites that provide astronomical ephemerides, prediction of phenomena, and astronomical reference data to the scientific community and public.

5. Promote the development of explanatory material that fosters better understanding of the use and bases of ephemerides and related data.
