Caledogonia,a new smooth trigoniacean bivalve from the Triassic of New Caledonia

Caledogonia globosa gen. et sp. nov. is considered to be a member of the Myophoriidae following the classification of Newell & Boyd (1975). It is a more evolved genus than Agonisca Fleming from the Ladinian of New Zealand. Both are probably the descendants of Neoschizodus of the Andean-West Antarctic region, a dispersal route on the southern Gondwanaland coastline. Caledogonia was probably a rapid burrower in a high energy paleoenvironment. It occurs in a rhythmic sequence of greywackes and conglomeratic shell beds that lie on pre-Triassic basement. Like the associated bivalves, Maoritrigonia and Manticula, Caledogonia is an endemic genus of the Late Triassic Maorian Province.

Caledogonia globosa gen. et sp. nov. est a rapporter aux Myophoriidae, d'après la classification de Newell & Boyd (1975). Plus évolué que le genre Agonisca Fleming du Ladinien de Nouvelle Zélande, il descend probablement, comme celuici de Neoschizodus représenté dans la region Andine et West Antarctique, zone de dispersion faunique de la cote Sud des Terres de Gondwana. Caledogonia, était un fouisseur actif dans un paléoenvironnement de haute énergie et de sédimentation rapide. On le trouve aujourdhui dans une séquence rythmique de grauwackes alternant avec des lumachelles et conglomérats, transgressive sur le substratum antétriasique. Comme les bivalves associés Maoritrigonia et Manticula, Caledogonia est un genre endémique de la province máorie du Trias supérieur.     

Where Angels Fear to Tread: Academics,Public Engagement and Popular History

Academic researchers are under growing pressure to disseminate their scholarship and demonstrate its impact beyond the academy. In Australia, Europe and the UK, higher education and research councils are taking increasing account of knowledge exchange and public engagement in their allocation of funding. In this issue of Victorians Beyond the Academy, Julie-Marie Strange reviews The Gangs of Manchester by Andrew Davies and the play it inspired, Angels with Manky Faces by MaD Theatre Company. Strange and Davies then discuss the opportunities and challenges involved in working with artists and performers, and reaching readers and audiences, outside the university sector.     

The Statistical Modeling of Flow Data When the Poisson Assumption Is Violated

The Poisson model typically provides a poor fit to flow data but more complex models are difficult to operationalize, especially with production or attraction constraints. Quasi- and pseudo-likelihood approaches retain the attractive computational features of the Poisson model. A shopping model example suggests the latter approach to be preferable.
