Members of the Union of Australian Women with banner during Hiroshima Day 1964, Brisbane, Australia. The Union of Australian Women is a national organisation that was formed in 1950. Its aim is to work for the status and wellbeing of women across the world. It has been involved in a wide variety of campaigns that concern women. The Union of Australian Women networks with other women's community and union groups on such issues.

Characterization of the EphA1 receptor tyrosine kinase: Expression in epithelial tissues

The Eph family (of receptor tyrosine kinases plays a crucial role during development and is implicated in oncogenesis. Using a partial cDNA clone of an Eph-related kinase (Esk) we isolated the complete coding region of a gene which we show to be murine EphA1 by both structural and functional criteria. The chromosomal localization is shown to be syntenic to hEphA1 and the genomic organization also shows distinct features found in the hEphA1 gene. Functionally, in keeping with findings for the human homologue, both soluble recombinant and native mEphA1 show preferential binding to ephrin A1. However, we also observed significant binding to other A-type ligands as has been observed for other Eph receptors. We analysed the expression of mEphA1 mRNA by in situ hybridization on tissue sections. mEphA1 was expressed in epithelial elements of skin, adult thymus, kidney and adrenal cortex. Taken together with previous Northern blotting data these results suggest that mEphA1 is expressed widely in differentiated epithelial cells.

Antagonism of the two-needle pine stem rust fungi Cronartium flaccidum and Peridermium pini by Cladosporium tenuissimum in vitro and in planta

Selected isolates of Cladosporium tenuissimum were tested for their ability to inhibit in vitro aeciospore germination of the two-needle pine stem rusts Cronartium flaccidum and Peridermium pini and to suppress disease development in planta. The antagonistic fungus displayed a number of disease-suppressive mechanisms. Aeciospore germination on water agar slides was reduced at 12, 18, and 24 h when a conidial suspension (1.5 x 10(7) conidia per ml) of the Cladosporium tenuissimum isolates was added. When the aeciospores were incubated in same-strength conidial suspensions for 1, 11, 21, and 31 days, viability was reduced at 20 and 4 degreesC. Light and scanning electron microscopy showed that rust spores were directly parasitized by Cladosporium tenuissimum and that the antagonist had evolved several strategies to breach the spore wail and gain access to the underlying tissues. Penetration occurred with or without appressoria. The hyperparasite exerted a mechanical force to destroy the spore structures (spinules, cell wall) by direct contact, penetrated the aeciospores and subsequently proliferated within them. However, an enzymatic action could also be involved. This was shown by the dissolution of the host tell wall that comes in contact with the mycelium of the mycoparasite, by the lack of indentation in the host wall at the contact site, and by the minimal swelling at the infecting hyphal tip. Culture filtrates of the hyperparasite inhibited germination of rust propagules. A compound purified from the filtrates was characterized by chemical and spectroscopic analysis as cladosporol, a known beta -1,3-glucan biosynthesis inhibitor. Conidia of Cladosporium tenuissimum reduced rust development on new infected pine seedlings over 2 years under greenhouse conditions. Because the fungus is an aggressive mycoparasite, produces fungicidal metabolites, and can survive and multiply in forest ecosystems without rusts, it seems a promising agent for the biological control of pine stem rusts in Europe.

Workplace familism and psychological contract breach in the Philippines

The present study addresses the call for theory-based investigations on workplace familism. It contributes to the literature by proposing and testing the moderating role of workplace familism between psychological contract breach and civic virtue behaviour. We surveyed 267 full-time employees and found main effects of both types of workplace familism (i.e. workplace organisational and workplace supervisor familism) and breach of relational obligations on civic virtue behaviour. Workplace supervisor familism also moderated the relationship between breach and civic virtue behaviour, with the negative relationship between breach and civic virtue behaviour stronger when workplace supervisor familism was high. This suggests that employees with a high level of workplace supervisor familism may feel a sense of betrayal and, therefore, respond more negatively to contract breach. Implications for practice and directions for future research are discussed.

Liberal Democracy and the Inferior 'Other'Other’: Could the peace liberal democracy promises to bring not extend to ‘Others’?

Advocates of liberal democracy argue that its principles and practices contribute directly to peace (at both inter-state and domestic levels). They rely on ideals such as the rule of law, institutional checks and balances on power, an ethos of tolerance, and free market economics to deliver the liberal peace. Liberals, however, overlook three important features embedded in the construction of liberal democracy which can serve to facilitate political violence: 1) the fixed and thus non-negotiable nature of liberal democracy’s core principles, 2) the inferior manner in which it conceives ‘Other’ social orders that do not share its core principles, and 3) the urge to proselytise Others. Together, these constitutive qualities can facilitate moves by leaders of Other groups to argue that liberal democracy threatens ‘their’ preferred identity, and thus its promised peaceful outcomes can be put in doubt.
