The desirability of criminal penalties for breaches of part IV of the trade practices act

Following the introduction of criminal sanction, including jail terms, for hard core cartelisation in the United Kingdom, the Dawson Review has recently recommended that criminal penalties be introduced in Australia for individuals and corporations found to have engaged in hard core cartels. A number of reasons have been advanced to justify the introduction of criminal sanctions for this type of conduct, the most common of which are that it would bring Australia in line with other competition regimes and that criminal sanctions are more likely to provide an effective deterrent. This article evaluates those reasons, and others, to determine whether there is any adequate justification for the proposed criminal regime.

That's doctor Ginibi to you : hard lessons in the history and publication of Ruby Langford Ginibi

On May Day this year at La Trobe University, a woman who hasblazed the trail of die hard Australian political writing for the past decade finally got some of her due. Ruby Langford - Ginibi in her Bundjalung language - took on the mantle of Honorary Doctor of Letters with all the grace and majesty of her namesake, the black swan. Doctor Ginibi seems a far cry from the Koori woman who built fences in the scrub, fought on the streets for Aboriginal justice, and can show you some pretty angry scars to prove it. Yet the Koori writer, educator, grandmother, auntie and activist reckons it is all part of the same history, all another step in the struggle to realise the justice for her mob that is not only slow coming but, even as she dons the robes of those she is asked to re-educate Koori way, draws further and further into the neocolonial distance.

Wear characteristics of ultra-hard cutting tools when machining austempered ductile iron

Nodularised Ductile Cast Iron, when subjected to heat treatment processes - austenitising and austempering produces Austempered Ductile Iron (ADI). The microstructure of ADI also known as "ausferrite" consists of ferrite, austenite and graphite nodules. Machining ADI using conventional techniques is often a problematic issue due to the microstructural phase transformation from austenite to martensite during machining. This paper evaluates the wear characteristics of ultra hard cutting tools when machining ADI and its effect on machinability. Machining trials consist of turning ADI (ASTMGrade3) using two sets of PCBN tools with 90% and 50% CBN content and two sets of ceramics tools; Aluminium Oxide Titanium Carbide and Silicon Carbide - whisker reinforced Ceramic. The cutting parameters chosen are categorized as roughing and finishing conditions; the roughing condition comprises of constant cutting speed (425 m/min) and depth of cut (2mm) combined with variable feed rates of 0.1, 0.2, 0.3 and 0.4mm/rev. The finishing condition comprises of constant cutting speed (700 m/min) and depth of cut (0.5mm) combined with variable feed rates of 0.1, 0.2, 0.3 and 0.4mm/rev. The benchmark condition to evaluate the performance of the cutting tools was tool wear evaluation, surface texture analysis and cutting force analysis. The paper analyses thermal softening of the workpiece by the tool and its effect on the shearing mechanism under rough and finish machining conditions in term of lower cutting forces and enhanced surface texture of the machined part.
