Eyeball Position in Facial Approximation: Accuracy of Methods for Predicting Globe Positioning in Lateral View

This study measured the accuracy of traditional and validated newly proposed methods for globe positioning in lateral view. Eighty lateral head cephalograms of adult subjects from Central Europe were taken, and the actual and predicted dimensions were compared. The anteroposterior eyeball position was estimated as the most accurate method based on the proportion of the orbital height (SEE = 1.9 mm) and was followed by the “tangent to the iris method” showing SEE = 2.4 mm. The traditional “tangent to the cornea method” underestimated the eyeball projection by SEE = 5.8 mm. Concerning the superoinferior eyeball position, the results showed a deviation from a central to a more superior position by 0.3 mm, on average, and the traditional method of central positioning of the globe could not be rejected as inaccurate (SEE = 0.3 mm). Based on regression analyzes or proportionality of the orbital height, the SEE = 2.1 mm.

Effective Corporatisation Legislation: The Fundamental Issue in Port Management

It is now some seven years since the restructure of Australian ports and their transformation into corporatised entities. This strategy was adopted in an endeavour to improve efficiency by distancing government from day to day operations - that element that was perceived to be the cause of sub-optimal performance. While there is widespread agreement that port performance has improved significantly, dissatisfaction persists and the belief that continued political intervention is preventing ports' commercial potential from being realised. This paper investigates these issues but argues that political intervention per se should not be the focus of research as the fundamental cause of sub-optimal performance. Rather political intervention is an effect of a more fundamental problem — an inappropriate legislative framework — and the focus of research should be on the legislation and corporatisation model in which political intervention is mandatory.     

Jurisdictional and constraints on effective competition: The case of rail access regimes

The Commonwealth Government in November 2002 released the AusLink Green Paper which is a blue print for a long term national land transport plan. The release of this document followed the Review of the National Road Transport Commission Act 1991 which recommended the abolition of the Australian Road Transport Commission and to replace it with a National Transport Commission – the new body which would have the responsibility for a national approach to both road, rail and intermodal development. AusLink was established in July 2004 and while an excellent government strategy, a national land transport plan demands the inclusion of an integrated rail network. Prior obstacles to the development of a national focus in rail have been overcome – gauge standardisation of the track and the abolition of state government monopolies. Despite deregulation, however, and the removal of the physical and jurisdictional constraints, other impediments are now appearing which are likely to prevent the effective implementation of a national focus. This is a product of the mechanism of deregulation itself and the development of state based and state focused access regimes which are now a barrier to the effective implementation of national network.
