Literary scholars and linguists have argued extensively that language is not simply a purely representational vehicle of thought but its determining medium, whose ordering powers not only shape cognizance of reality but are also actively involved in processes of imperialism and cultural erasure. It is the determinative yet slippery quality of language, prompting the loss of meaning in attempts at translation, that colonial powers manipulated to violent effect and which, as enacted in the plays of Nyoongah Indigenous Australian playwright Jack Davis, continue to haunt history and the present. This article considers how a history and culture made unspeakable by colonialism through the erasure of Indigenous Australian oral traditions, languages, and historical perspectives is translated on to the Anglophone stage in the plays of Davis, one of the first Indigenous playwrights to be published and performed internationally, and how this was received by the witnessing audience. Davis achieves this theatrical translation not only through the negotiation and manipulation of colonial language and verbatim history alongside Indigenous languages, enacting a kind of linguistic double consciousness, but also through physical theatre and dance. The latter are the central means of communicating meaning and knowledge in Nyoongah culture. Jacqueline M.

Significant new opportunities for astrophysics and cosmology have been identified at low radio frequencies. The Murchison Widefield Array is the first telescope in the southern hemisphere designed specifically to explore the low-frequency astronomical sky between 80 and 300 MHz with arcminute angular resolution and high survey efficiency. The telescope will enable new advances along four key science themes, including searching for redshifted 21-cm emission from the EoR in the early Universe; Galactic and extragalactic all-sky southern hemisphere surveys; time-domain astrophysics; and solar, heliospheric, and ionospheric science and space weather. The Murchison Widefield Array is located in Western Australia at the site of the planned Square Kilometre Array (SKA) low-band telescope and is the only low-frequency SKA precursor facility. In this paper, we review the performance properties of the Murchison Widefield Array and describe its primary scientific objectives.

Sex attraction studies were carried out to investigate the mate-finding behaviour of invasive Vespula vulgaris (Linnaeus) (Hymenoptera: Vespidae) wasps. Delta traps were baited with live, caged males, and gynes (virgin queens) of V. vulgaris to determine whether either sex produced a long-range sex attractant. Traps baited with gynes caught 71 males, while the controls and live-male wasp baited traps did not catch gynes. Wind tunnel trials were performed to verify if the signal produced by the gynes was chemical in nature. First, V. vulgaris males were flown to live caged gynes, where more than half of the males tested flew upwind in a zigzagging pattern and made contact with caged gynes. Males were also flown to hexane rinses of gynes and flew upwind in a zigzagging pattern towards the gyne extract, although none made contact with the cotton roll stimulus. The results presented here demonstrate conclusively that V. vulgaris gynes produce a sex pheromone.
