A Study of the Role of Regionalization in the Generation of Aggregation Error in Regional Input –Output Models

Although the need for aggregation in input –output modelling has diminished with the increases in computing power, an alarming number of regional studies continue to use the procedure. The rationales for doing so typically are grounded in data problems at the regional level. As a result many regional analysts use aggregated national input –output models and trade –adjust them at this aggregated level. In this paper, we point out why this approach can be inappropriate. We do so by noting that it creates a possible source of model misapplication (i.e., a direct effect could appear for a sector where one does not exist) and also by finding that a large amount of error (on the order of 100 percent) can be induced into the impact results as a result of improper aggregation. In simulations, we find that average aggregation error tends to peak at 81 sectors after rising from 492 to 365 sectors. Perversely, error then diminishes somewhat as the model size decreases further to 11 and 6 sectors. We also find that while region – and sector –specific attributes influence aggregation error in a statistically significantly manner, their influence on the amount of error generally does not appear to be large.     

Still Under the Act? Subjectivity and the State in Aboriginal North Queensland

ABSTRACT Both the colonial encapsulation and post‐colonial recognition of North Queensland's Aboriginal population have been achieved through legislative demarcation. This paper explores the way such demarcation has extended the influence of the state within local Aboriginal life‐worlds, focusing on the State of Queensland's Aboriginals Protection and Restriction of the Sale of Opium Act 1897 and the Commonwealth's Native Title Act 1993. Drawing on ethnographic and historical material from Central Cape York Peninsula, and recent anthropological theorization of the state, I argue that anthropologists need to seriously consider Aboriginal claims about what Michel‐Rolph Trouillot calls ‘state effects’. But careful examination of these claims suggests that the state no longer simply imposes its projects on fundamentally distinct Aboriginal life‐worlds. Not only is the state now deeply engaged within these life‐worlds, it is also deeply interwoven into post‐colonial Aboriginal subjectivities.     

Dental caries in an Early Cretaceous ichthyosaur

A single anterior dentary tooth, recovered with a near complete juvenile ichthyosaur skull from the Early Cretaceous (upper Albian) Hughenden-Richmond region of northern Queensland, has revealed the presence of a potential dental caries (tooth decay) infection. Dental caries is a disease affecting hard dental structures including the cementum and results in cavitation. The implications of dental caries development on tooth replacement and feeding in Cretaceous ichthyosaurs are discussed.     

A Feasibility Study for the Investigation of Submerged Sites along the Coast of Slovenia

Maritime investigations along the Northern Adriatic coast have traditionally focused on the Roman and later archaeology. However, studies of post-glacial sea-level change and shoreline displacement suggest there is significant potential for the discovery of sites close inshore dating back to the early- to mid-Holocene, c .9000 BC onwards. A feasibility study for the investigation of submerged sites along the coast of Slovenia was undertaken in 2005. Here we describe the project rationale and research design, the survey and recording methods used, the logistical problems encountered, the results obtained (regardless of age), and the prospects for future research in the region.
