Does prosecuting perpetrators of repression under a dictatorship promote public support for human rights and the courts? We argue that convicting perpetrators in human rights trials reduces public acceptance of these violations. However, while convictions signal judicial efforts to end impunity, they may also call attention to the politicized process by which transitional justice begins. We estimate the effects of human rights trial verdicts on attitudes in Argentina, a country ruled by a military dictatorship from 1976–1983 that, twenty-five years later, initiated sweeping human rights trials for past repression. Using observational day-level opinion data from a survey fielded around the guilty verdict for one of the dictatorship’s top-ranking generals, we find the trial verdict increased the public’s rejection of torture and political killings. Yet belief in judicial fairness declined. These results suggest that trials solidify public commitments to human rights, but confidence in the judiciary is not a necessary condition for this effect.

How do international sports events shape repression in authoritarian host countries? International tournaments promise unique gains in political prestige through global media attention. However, autocrats must fear that foreign journalists will unmask their wrongdoings. We argue that autocracies solve this dilemma by strategically adjusting repression according to the spatial-temporal presence of international media. Using original, highly disaggregated data on the 1978 World Cup, we demonstrate that the Argentine host government largely refrained from repression during the tournament but preemptively cleared the streets beforehand. These adjustments specifically occurred around hotels reserved for foreign journalists. Additional tests demonstrate that (1) before the tournament, repression turned increasingly covert, (2) during the tournament, targeting patterns mirrored the working shifts of foreign journalists, (3) after the tournament, regime violence again spiked in locations where international media had been present. Together, the article highlights the human costs of megaevents, contradicting the common whitewashing rhetoric of functionaries.

Authoritarian regimes repress to prevent mass resistance to their rule. In doing so, regimes’ security forces require information about the dissidents who mobilize such resistance. Political competition, which fuels partisan rivalries, offers one solution to this problem by motivating civilians to provide needed information to security forces. Yet civilians share information about any political opponents, not just dissidents, which creates a challenge for regimes that want to target dissidents. Drawing on novel archival data from the immediate aftermath of the 1973 coup that brought Augusto Pinochet to power in Chile, a period that included civilian collaboration with repression, this article presents evidence that close pre-coup political competition is associated with more frequent repression and more targeting of non-dissidents. The author uses pre-coup democratic elections to measure political competition and addresses the challenge of estimating political preferences unaffected by repression. Qualitative evidence and further quantitative tests probe implications of the partisan rivalry mechanism and account for alternative explanations.

In this paper, we describe the system design and capabilities of the Australian Square Kilometre Array Pathfinder (ASKAP) radio telescope at the conclusion of its construction project and commencement of science operations. ASKAP is one of the first radio telescopes to deploy phased array feed (PAF) technology on a large scale, giving it an instantaneous field of view that covers $31\,\textrm{deg}^{2}$ at $800\,\textrm{MHz}$. As a two-dimensional array of 36$\times$12 m antennas, with baselines ranging from 22 m to 6 km, ASKAP also has excellent snapshot imaging capability and 10 arcsec resolution. This, combined with 288 MHz of instantaneous bandwidth and a unique third axis of rotation on each antenna, gives ASKAP the capability to create high dynamic range images of large sky areas very quickly. It is an excellent telescope for surveys between 700 and $1800\,\textrm{MHz}$ and is expected to facilitate great advances in our understanding of galaxy formation, cosmology, and radio transients while opening new parameter space for discovery of the unknown.

The success of protests depends on whether they favorably affect public opinion: nonviolent resistance can win public support for a movement, but regimes counter by framing protest as violent and instigated by outsiders. The authors argue that public perceptions of whether a protest is violent shift based on the framing of the types of action and the identities of participants in those actions. The article distinguishes between three dimensions: (1) threat of harm, (2) bearing of arms and (3) identity of protesters. Using survey experiments in Israel and the United States, the study finds support for framing effects. Threat of harm has the largest positive effect on perceptions of violence and support for repression. Surprisingly, social out-groups are not perceived as more violent, but respondents favor repressing them anyway. Support for repressing a nonthreatening out-group is at least as large as support for repressing a threatening in-group. The findings link contentious action and public opinion, and demonstrate the susceptibility of this link to framing.

We describe the performance of the Boolardy Engineering Test Array, the prototype for the Australian Square Kilometre Array Pathfinder telescope. Boolardy Engineering Test Array is the first aperture synthesis radio telescope to use phased array feed technology, giving it the ability to electronically form up to nine dual-polarisation beams. We report the methods developed for forming and measuring the beams, and the adaptations that have been made to the traditional calibration and imaging procedures in order to allow BETA to function as a multi-beam aperture synthesis telescope. We describe the commissioning of the instrument and present details of Boolardy Engineering Test Array’s performance: sensitivity, beam characteristics, polarimetric properties, and image quality. We summarise the astronomical science that it has produced and draw lessons from operating Boolardy Engineering Test Array that will be relevant to the commissioning and operation of the final Australian Square Kilometre Array Path telescope.

This paper describes the system architecture of a newly constructed radio telescope – the Boolardy engineering test array, which is a prototype of the Australian square kilometre array pathfinder telescope. Phased array feed technology is used to form multiple simultaneous beams per antenna, providing astronomers with unprecedented survey speed. The test array described here is a six-antenna interferometer, fitted with prototype signal processing hardware capable of forming at least nine dual-polarisation beams simultaneously, allowing several square degrees to be imaged in a single pointed observation. The main purpose of the test array is to develop beamforming and wide-field calibration methods for use with the full telescope, but it will also be capable of limited early science demonstrations.

The 26 December 2004 Tsunami resulted in a death toll of >270,000 persons, making it the most lethal tsunami in recorded history. This article presents performance data observations and the lessons learned by a civilian team dispatched by the Australian government to “provide clinical and surgical functions and to make public health assessments”. The team, prepared and equipped for deployment four days after the event, arrived at its destination 13 days after the Tsunami. Aspiration pneumonia, tetanus, and extensive soft tissue wounds of the lower extremities were the prominent injuries encountered. Surgical techniques had to be adapted to work in the austere environment. The lessons learned included: (1) the importance of team member selection; (2) strategies for self-sufficiency; (3) personnel readiness and health considerations; (4) face-to-face handover; (5) coordination and liaison; (6) the characteristics of injuries; (7) the importance of protocols for patient discharge and hospital staffing; and (8) requirements for interpreter services.

Whereas disaster medical relief teams will be required in the future, the composition and equipment needs will differ according to the nature of the disaster. National teams should be on standby for international response.

Prescription-event monitoring (PEM) is one of two national systems of drug safety monitoring practised in Britain. The objective of this PEM study was to assess the safety of fluvoxamine and to monitor the occurrence of untoward and other events during treatment. A total of 10 401 patients treated with the drug in general practices throughout England were studied and data were analysed in the Drug Safety Research Unit, Southampton. The main outcome measures were the overall incidence of events per 1000 patients; the incidence during the first month of treatment; the mean incidence for months 2–6 of treatment; and the ratio of these rates as a signal that an event could be drug related. The most commonly reported category of events was neuropsychiatric while the most commonly reported individual events were nausea and vomiting. Fluvoxamine was shown to be a safe drug and no unexpected or previously undetected drug-related events were encountered. There was a relatively high incidence of gastro-intestinal symptoms, but other adverse reactions often encountered during treatment with tricyclic antidepressants were not frequently reported.

‘Prescription-event monitoring’ (PEM) is one of two national systems of post-marketing surveillance in operation in Britain. It identified 22 065 patients who had received NHS prescriptions for alprazolam, and data available on 10 895 of these were analysed. The main reasons for treatment with alprazolam were anxiety and depression. The patients provided 3360 patient-years of treatment and 7540 patient-years of follow-up. No serious events clearly associated with treatment were recorded. The main events reported during treatment, albeit infrequently, were drowsiness and depression, although depression is more likely to be due to the disorder being treated than to the drug. Some of the other alleged unwanted effects of alprazolam in published reports were not encountered. Since PEM is unable to determine the dependence potential of alprazolam, further evaluation of this problem is called for.
