Sustainable Management of the Great Artesian Basin: an analysis based on Environmental Economics and Law

Groundwater has been a vital resource to humans through the ages. Ancient societies depended on the ability to construct and maintain useful wells. The Persians had systems of qanats as far back as 1500 BC. These were underground conduits for tapping groundwater made by sinking a series of wells and connecting them. The technology was also used in Roman aqueducts, and brought by Arabs to North Africa and Spain. The story of the exploitation of Australia's groundwater resources is of far more recent vintage. Interstate rivalry over the control of surface water resources has been recognised as a factor shaping our federal constitution, but few realise how much the management of our underground water resources is interwoven with our colonial history. In important respects, both the policy debate and the development of institutions to manage groundwater have run in parallel with that of policies regarding surface water. The parallels are particularly close regarding two of Australia's most significant resources of each kind: the Murray-Darling Basin and the Great Artesian Basin. Policy, management structures and remedial solutions developed in response to the problems of the Murray-Darling Basin tend to set the tone for discussion of the Great Artesian Basin, in some cases to the point where ideas developed for management of the Murray-Darling Basin are applied directly to the Great Artesian Basin. The purpose of this article is to provide a framework for discussion of the current policy issues surrounding management of the Great Artesian Basin, with reference to the historical development of existing legislation and institutions. Of interest is the applicability of lessons learned from the debate over management of the Murray-Darling Basin

Productivity Impact of IT Investment in Singapore

While much empirical research has been done on the “productivity paradox” problem in the United States (for a recent survey, see Brynjolfsson 1993), there has been little comparable research among newly industrializing economies (NIES). The recent work of Kraemer and Dedrick (1993) shows some correlation of XT investment-GDP ratio with GDP growth rate for a cross section of eleven Asia-Pacific economies, but since no attempt is made to control for other influencing factors (e.g., non-IT related investment), such correlations may be spurious. Whether NI& face the productivity paradox therefore remains an open question

KINEMATIC ANALYSIS OF JUNIOR WOMEN HURDLING

The purpose of this study is to provide a kinematic analysis of the hurdling techniques of two junior women hurdlers to ascertain the importance of speed and technique in hurdling. Kinematic performance variables including the horizontal and vertical velocities at takeoff and landing, the clearance distance and the flight lime were obtained an-d analyzed. In order to evaluate the techniques used by the two junior hurdlers, their hurdling performance variables were compared with the published data of Coh et al. (1998) of an elite hurdler. The junior hurdlers had a higher take-off angle (23.5 0) at hurdle clearance compared to the elite hurdler (10 0) The take-off distance (1.62 m) was also closer to the hurdle than the elite hurdler (2.09 m). This may suggest that the junior hurdlers lack 'horizontal speed and hence adopted a less efficient hurdle clearance technique

Is there a need for a specific educational scholarship for using e-learning in medical education?

We propose the need for a specific educational scholarship when using e-learning in medical education. Effective e-learning has additional factors that require specific critical attention, including the design and delivery of e-learning. An important aspect is the recognition that e-learning is a complex intervention, with several interconnecting components that have to be aligned. This alignment requires an essential iterative development process with usability testing. Effectiveness of e-learning in one context may not be fully realized in another context unless there is further consideration of applicability and scalability. We recommend a participatory approach for an educational scholarship for using e-learning in medical education, such as by action research or design-based research

Micro-Scholarship: An Innovative Process Using Common Technology Tools

Micro-Scholarship is a flexible process that eases an educator’s scholarly journey by making their small steps (MicroAssets) visible, assessable, stackable, and transferable. This process uses existing technology tools and relationships in a stepwise and supported manner to create Macro-Assets (traditional scholarly outcomes) including articles, presentations, and workshop
