Players, clubs, events and the Trade Practices Act : a primer for sporting clubs

The Trade Practices Act (TPA) has had an enormous impact on how corporations in Australia may conduct their business. In relation to sporting clubs, it limits the freedom of clubs to deal with players, each other and the public. While previously many clubs may have escaped the ambit of the TPA because they were not “corporations”, state equivalent Fair Trading legislation and the introduction of the national competition policy in 1995 have effectively expanded the scope of consumer and competition regulation to include individuals and associations. Consequently, an understanding of the nature and scope of trade practices regulation is now important for any sporting organisation—regardless of size or structure. This paper identifies the legislative provisions most likely to impact upon sporting clubs and examines some possible circumstances in which clubs might find themselves exposed to liability.

Assessment of competency : a primer

Determination of testamentary capacity involves not only application of standard tests for decisional competency but also consideration of such special factors as the testator's "moral duty" to those entitled to her or his bounty (also referred to as "common obligations of life"), and the concept of emotional capacity. It is important for medical and legal practitioners who are involved in assessment of testamentary capacity to be aware of these special factors or requirements, their nature and their effect on the validity of the testator's will. The relevant tests and special factors are examined from an historical perspective.

Project quality management in virtual environments : a primer

The rise of geographically dispersed project teams enabled by technology has made project quality management a significant challenge for organizations. This paper uses findings from a project on geographically dispersed, cooperating SMEs in the building trade, to explore whether concepts and artefacts from the Rational Unified Process® (RUP®) software development approach could be adapted and used to better manage quality in virtual projects. Our future research aims to explore the use of RUP artefacts in a virtual environment and their impact on
project management and quality.

A primer on mathematical modelling in economics

The Commission on Graduate Education in Economics had raised several concerns regarding the role of mathematics in graduate training in economics (Krueger, 1991; Colander, 1998, 2005). This paper undertakes a detailed scrutiny of the notion of a utility function to motivate and describe the common patterns across mathematical concepts and results that are used by economists. In the process one arrives at a classification of mathematical terms which is used to state mathematical results in economics. The usefulness of the classification scheme is illustrated with the help of a discussion of Arrow's impossibility theorem. Common knowledge of the patterns in mathematical concepts and results could be effective in enhancing communication between students, teachers and researchers specializing in different sub-fields of economics.

Effects of alterations of primer-binding site sequences on human immunodeficiency virus type 1 replication

The human immunodeficiency virus type 1 genomic RNA primer-binding site (PBS) sequence comprises 18 nucleotides which are complementary to those at the 3' end of the replication initiation primer tRNA(3Lys). To investigate the role of the PBS in viral replication, we either deleted the original wild-type PBS (complementary to tRNA(3Lys) or replaced it with DNA sequences complementary to either tRNA(1,2Lys) or tRNA(Phe). Transfection of COS cells with such molecular constructs yielded similar levels of viral progeny that were indistinguishable with regard to viral proteins and tRNA content. Virus particles derived from PBS-deleted molecular clones were noninfectious for MT-4, Jurkat, and CEM-T4 cells. However, infectious viruses were derived from constructs in which the PBS had been altered to sequences complementary to either tRNA(1,2Lys) or tRNA(Phe), although mutated forms showed significant lags in replication efficiency in comparison with wild types. Molecular analysis of reverse-transcribed DNA in cells infected by the mutated viruses indicated that both tRNA(1,2Lys) and tRNA(Phe) could function as primers for reverse transcription during the early stages of infection. Sequencing of full-length proviral DNA, obtained 6 days after infection, revealed the mutated PBS, indicating that a complete cycle of reverse transcription had occurred. During subsequent rounds of infection, reversion of the mutated PBS to wild-type sequences was observed, accompanied by increased production of viral gene products. Reversion to wild-type PBS sequences was confirmed both by specific PCR analysis, using distinct primer pairs, and by direct sequencing of amplified segments. We also performed endogenous in vitro reverse transcription experiments in which synthesis of minus-strand strong-stop viral DNA was primed from a synthetic RNA template containing a PBS complementary to various tRNA isoacceptors. These results showed that tRNA(3Lys) was a much more efficient primer of such reactions than either tRNA(1,2Lys) or tRNA(Phe).
