Case note - Roosters, ducks and labour hire arrangements : Damevski v Guidice (2003) 202 ALR 494 (FCA Full Court)

One of the features of the current Australian labour market is the growth in the number of businesses "contracting out" work that was previously performed by their employees. The "contracting out" is often done through labour hire arrangements: the business engages a labour hire agency to provide it with suitable labour on an "as needs" basis. A common scenario is that the labour hire agency contracts both with the workers who provide the services to the agency's client, and with the client to whom those services are provided. Often the agency pays the workers and bills its client for the labour costs, plus a service fee. Research indicates that during the first half of the 1990s, "the number of agency workers more or less doubled."1 Analysis of the latest data from the Australian Bureau of Statistics on the number of workers employed through labour hire arrangements has suggested: "290,100 employees were 'on-hired' through agencies in June 2002 and 162,000 workers were paid by labour hire firms in November 2001 (almost doubling from 84,300 some three years earlier)." The value of the employment services industry in 2001-02 was $10.2 billion. 2

The medical provision of hydration and nutrition: Two very different outcomes in Victoria and Florida

Decisions to withhold or withdraw medical hydration and nutrition are amongst the most difficult that confront patients and their families, medical
and other health professionals all over the world. This article discusses two cases relating to lawful withdrawal and withholding of a percutaneous endoscopic gastrostomy tube (PEG) from incompetent patients with no hope of recovery. Victoria and Florida have statutory frameworks that provide for advance directives, however in both Gardner; Re BWV and Schindler v Schiavo; Re Scliiavo the respective patients did not leave documented instructions. The article analyses the two cases and their outcomes from legal, medical and ethical perspectives.

Synthesis and structure of bis(para-methoxyphenyl)selenoxide and its monohydrate. theoretical considerations of the hydration of diorganoselenium oxides

The title compound was prepared by base hydrolysis of (p-MeOC₆H₄)₂SeCl₂ in water and isolated as the crystalline monohydrate, (p-MeOC₆H₄)₂SeO·H₂O, in which the water molecule is associated via hydrogen-bonding. Water-free (p-MeOC₆H₄)₂SeO was obtained crystalline after drying and recrystallisation from toluene. Both crystal phases were investigated by single crystal X-ray diffraction. Preliminary DFT calculations at the B3LYP/LANL2DZdp level of theory suggest that the hydrogen bonded complexes R₂SeO·H₂O (R = H, Me, Ph) are by 2.79, 3.36 and 11.10 kcal mol^-1 more stable than the corresponding elusive diorganoselenium dihydroxides R₂Se(OH)₂. The hydrogen bond energies of R₂SeO·H₂O (R = H, Me, Ph) are 5.98, 7.18 and 5.89 kcal mol^-1.

The very C-terminus of protein kinase CĹ is critical for the full catalytic competence but its hydrophobic motif is dispensable for the interaction with 3-phosphoinositide-dependent kinase-1

In this article, we explore the role of the C-terminus (V5 domain) of PKCvar epsilon plays in the catalytic competence of the kinase using serial truncations followed by immune-complex kinase assays. Surprisingly, removal of the last seven amino acid residues at the C-terminus of PKCvar epsilon resulted in a PKCvar epsilon-Δ731 mutant with greatly reduced intrinsic catalytic activity while truncation of eight amino acid residues at the C-terminus resulted in a catalytically inactive PKCvar epsilon mutant. Computer modeling and molecular dynamics simulations showed that the last seven and/or eight amino acid residues of PKCvar epsilon were involved in interactions with residues in the catalytic core. Further truncation analyses revealed that the hydrophobic phosphorylation motif was dispensable for the physical interaction between PKCvar epsilon and 3-phosphoinositide-dependent kinase-1 (PDK-1) as the PKCvar epsilon mutant lacking both the turn and the hydrophobic motifs could still be co-immunoprecipitated with PDK-1. These results provide fresh insights into the biochemical and structural basis underlying the isozyme-specific regulation of PKC and suggest that the very C-termini of PKCs constitute a promising new target for the development of novel isozyme-specific inhibitors of PKC.

The reactivity of bis(para-methoxyphenyl)telluroxide towards triflic acid and diphenylphosphinic acid. Theoretical considerations of the protonation and hydration process of diorganotelluroxanes

The reaction of (p-MeOC₆H₄)₂TeO with two equivalents of HO₃SCF₃ and HO₂PPh₂ provided the tetraorganoditelluroxanes (F₃CSO₃)(p-MeOC₆H₄)₂TeOTe(p-MeOC₆H₄)₂(O₃SCF₃) (1) and (Ph₂PO₂)(p-MeOC₆H₄)₂TeOTe(p-MeOC₆H₄)₂(O₂PPh₂)·2 Ph₂PO₂H (2) in good yields. Compounds 1 and 2 were characterized by solution and solid-state ³¹P and ¹²⁵Te NMR spectroscopy, IR spectroscopy, electrospray mass spectrometry, conductivity measurements and single crystal X-ray diffraction. In solution, compound 1 undergoes an electrolytic dissociation and reversibly reacts with traces of water to give the mononuclear cation [(p-MeOC₆H₄)₂TeOH]⁺ and triflate anions. Theoretical aspects of the protonation and hydration of model telluroxanes R₂TeO (R = H, Me, Ph) were investigated by preliminary DFT calculations and compared to the corresponding selenoxanes R₂SeO. The tellurium dihydroxides R₂Te(OH)₂ seem to be more stable than the hydrogen-bonded complexes R₂TeO·H₂O.

The last five amino acid residues at the C-terminus of PRK1 /KKN is essential for full lipid responsiveness

PRK1/PKN is a member of the protein kinase C (PKC) superfamily of serine/threonine protein kinases. Despite its important role as a RhoA effector, limited information is available regarding how this kinase is regulated. We show here that the last seven amino acid residues at the C-terminus is dispensable for the catalytic activity of PRK1 but is critical for the in vivo stability of this kinase. Surprisingly, the intact hydrophobic motif in PRK1 is dispensable for 3-phosphoinositide-dependent kinase-1 (PDK-1) binding and phosphorylation of the activation loop, as the PRK1-Δ940 mutant lacking the last two residues of the hydrophobic motif and the last 5 residues at the C-terminus interacts with PDK-1 in vivo and has a similar specific activity as the wild-type protein. We also found that the last four amino acid residues at the C-terminus of PRK1 is critical for the full lipid responsiveness as the PRK1-Δ942 deletion mutant is no longer activated by arachidonic acid. Our data suggest that the very C-terminus in PRK1 is critically involved in the control of the catalytic activity and activation by lipids. Since this very C-terminal segment is the least conserved among members of the PKC superfamily, it would be a promising target for isozyme-specific pharmaceutical interventions.

Full house theory: A new theory for assessing demand for arts centers

In this article I will establish an underpinning theory to apply in measuring demand for a new arts center (theater, museum, gallery, multipurpose space, tourism destination, or cultural precinct). The new theory is called "Full House Theory"-so called because it aims to provide an equation among the factors that result in maximum occupancy and use of an arts center or cultural facility. Existing theories used in the retail sector offer a distance-and-time analysis of expected customer demand but do not include differentiated product-demand analysis. Cultural planning literature examines community need in relation to cultural development but fails to provide a formula to predict sustainable demand. In addition, I will analyze the theories and methodologies in current use as well as their weaknesses in assessing cultural facility demand.

Talking it up! Project report : Aboriginal voices in the formulation of health policy that works : full report

Initially, there were three separate strands to the work of the project: a series of forums involving group interviews/discussions with community members; a policy analysis that reviewed policies relating to Aboriginal health at federal and state level; and a literature review. The results of these three separate strands of analysis were then brought together in a fourth strand to the work, a process involving community members to discuss and agree the overall recommendations contained in this report.

Through this structure, the project employed a participatory methodology as the basis for individual and collective empowerment in relation to health outcomes. As mentioned above, the need for the project was identified by Aboriginal people, through their own processes of healing. The need was presented by appropriate figures within their communities, namely community elders. They invited other Aboriginal people to take part through their own communication channels, thus ensuring that responsibility for engagement in the project, and in formulating action for improvement, remained with Aboriginal people and their families. However, the project design also recognised that Aboriginal people exist within broader structural and policy constraints which impact on their ability to manage their own lives successfully or otherwise. Thus the project sought to combine indigenous and non-indigenous knowledge through bringing together the three strands of work in the way described.

A Community Reference Group guided the work of the project at all stages, endorsed the findings and drafted the recommendations. The two elders who had identified the need for the project formed the core of the group, and worked on the project from start to finish. At different times during the project, other community members joined the group to assist in its work, including training Aboriginal researchers, letting others know about the forums, discussing findings and drafting recommendations.
