Developing a rural and regional science challenge to utilise community and industry-based partnerships

Interest and participation in science in schools has been declining for many years and there is a genuine need to rejuvenate interest in science at the high school level. One possible solution is the completion of challenging science projects which fulfill an authentic purpose in the community. This paper discusses the results of ongoing research into the establishment of a rural and regional Science Challenge which makes use of partnerships with local industries and community groups to encourage the development of authentic science projects. In the development of the Science Challenge, many issues are emerging in relation to teachers' work, resources, administration and school cultures. This paper reports on the preliminary findings and indicates directions for the future.

Promoting a team ball game (Lifeball) to older people : who does this game attract and who continues?

Issue addressed: To describe the demographic and health-related characteristics (physical activity, self-reported health status, quality of life and falls history) of older people who enroll in a team-based game, Lifeball, and examine associations between continuation and participant characteristics. Reasons for stopping, participants' perceptions of the game and changes in health-related characteristics over 12 months were examined.

Methods: Telephone surveys were conducted with a cohort of Lifeball players at: baseline, soon after commencing playing and 12 months later.

Results: At baseline, participants were aged 40 to 96 years (mean 67). Most were female (84%), in good to excellent health (86%) and reported being sufficiently (>150 minutes per week) physically active (69%). Almost half (43%) were still playing 12 months later (continuers). Continuers were more likely to perceive Lifeball had helped them to: feel fitter and healthier (91%); improve their social life (73%); and be more active (53%). No significant changes in continuers' physical activity, self-reported health status and quality of life measures were reported. The main reason for stopping playing was illness/injury unrelated to Lifeball.

Conclusions: Lifeball mainly appealed to healthy, active older people.

Janet Lady Clarke (1851-1909) 'Leader in the good work'

This thesis is a biographical study which examines the life and career of Janet Lady Clarke. As a leader of women's philanthrophic, health, educational and political organisations in nineteenth-century and early twentieth-century Victoria, she promoted new ideas within a conservative colonial society. Her legacies remain an integral part of Victoria's cultural heritage.

Alteration of the proline at position 7 of the HIV-1 spacer peptide p1 suppresses viral infectivity in a strain dependent manner

The HIV-1 spacer peptide p1 is located in the C-terminus of the Gag polyprotein and separates the nucleocapsid (NC) and p6(Gag). Research centered on p1 has been limited and as yet no function has been ascribed to this spacer peptide. We have previously found that the conserved p1 proline residues (position 7 and 13) are critical for replication in the HIV-1 strain HXB2-BH10. In this study we have focused on the proline rich p1-p6(Gag) C-terminus of HIV-1. We individually examined the role of p1 proline's in multiple strains of HIV-1 and investigated the role of three proline residues in p6(Gag) (P24, P25 and P30). Assessment of the HXB2-BH10 based mutants revealed that Gag-Pol incorporation relative to Gag decreased in the p1 mutant virions, with the double proline mutant the most impaired. Mutating both p1 proline residues was found to abolish infectivity in multiple strains of HIV-1. Independent mutation of the p1 proline at position 7 resulted in a strain-dependent suppression of viral infectivity. This defect correlates with the presence of a tyrosine residue at position 9 of p1 and occurs in the early phase of the HIV-1 replication cycle. The p1 proline residues were found to be functionally distinct from P24, P25 and P30 in p6(Gag). This work affords novel insights into our understanding of the role of p1 in HIV-1 replication.
