First probable Australian cases of human infection with Rickettsia felis (cat-flea typhus)

Human infection with Rickettsia felis has been reported in most parts of the world, and R. felis has recently been confirmed in cat fleas in Western Australia. The clinical presentations of R. typhi and R. felis are similar, and in the past, the incidence of R. felis infection may have been underestimated. We describe the first reported cases of probable human R. felis infection in Australia. Two adults and three children in Victoria contracted a rickettsial disease after exposure to fleas from kittens. Molecular testing of fleas demonstrated the presence of R. felis but not R. typhi.

Managerial share ownership and discretionary accruals in Australia : do independent and executive directors have different incentives?

We examine the relation between managerial share ownership (MSO) and discretionary accruals in Australia. We find a positive relation between MSO and discretionary accruals up to a certain level of MSO followed by a negative relation (inverse U-shaped). We suggest that these unique results are a result of certain Australian institutional features that are markedly different to those in the US and the UK and imply that the ownership-discretionary accruals relation is context specific with the wider corporate governance systems influencing the theorised incentive effects. We also posit that executive directors and independent directors have different ownership-discretionary accruals incentives and report results consistent with this proposition.

Moving beyond the restrictions : the evaluation of the Alice Springs alcohol management plan

There have been a number of evaluations of alcohol management in the Alice Springs region. Interestingly, an evaluation in 1975 emphasised the need for government and other agencies to view the issues holistically and to address them accordingly. The outcomes of this evaluation point to a similar situation with comparable recommendations.

The situation in Alice Springs is unique in some respects but has parallel characteristics to other towns and communities in Australia. Alice Springs is an important regional supply, service-orientated, and tourism town. Its people have diverse backgrounds and appear as durable as the environment they live in. Associated with this is a hard drinking culture that permeates the community with a range of issues regardless of one’s cultural background.

The research group found a community that in many ways is ruptured and fragmented when it comes to the ways and means of how such challenges can be confronted. This situation is exemplified by the perception that alcohol problems are confined to a minority of drinkers that seemingly pervades the dialogue surrounding drinking and its effects in the town.

Nevertheless, a positive outcome of such discourse is the fact that people do care about their community and are very keen to live in a town where there are more responsible attitudes toward drinking. There is some way to go; the first thing that everyone needs to accept is that it is a community problem. Non-Indigenous and Indigenous individuals, groups and organisations all have a responsibility therefore in addressing the challenges and working toward better solutions. Government have an important role of course, however the acceptance by the community that it is a community problem is paramount.

Some of the community and government initiatives are having a positive effect on drinking in the town. However, some of the initiatives, such as certain restrictions, can and should not be considered, on their own, as long-term solutions. Other processes need to be implemented, oversighted and managed in an effective manner. An important component of such processes is data that is well managed, available, and appropriate for those agencies involved.

A secure tag ownership transfer scheme in a closed loop RFID system

In this paper we propose a novel secure tag ownership transfer scheme for closed loop RFID systems. An important property of our method is that the ownership transfer is guaranteed to be atomic and the scheme is protected against desynchronisation leading to permanent DoS. Further, it is suited to the computational constraints of EPC Class-1 Gen-2 passive RFID tags as they only use the CRC and PRNG functions that passive RFID tags are capable of. We provide a detailed security analysis to show that our scheme satisfies the required security properties of tag anonymity, tag location privacy, forward secrecy, forward untraceability while being resistant to replay, desynchronisation and server impersonation attacks. Performance comparisons show that our scheme is practical and can be implemented on passive low-cost RFID tags.

Managerial share ownership and operating performance : do independent and executive directors have different incentives?

We investigate the relationship between managerial share ownership (MSO) and earnings as a measure of operating performance in Australia. To mitigate potential earnings management, we also use discretionary accrual adjusted earnings as an alternative measure of performance. We document a negative relation between MSO and performance followed by a positive relation. We suggest that these unique results are an artefact of certain Australian institutional features and imply that the ownership–performance relation is context-specific, with the wider corporate governance systems influencing the theorised incentive effects. We also posit that executive directors and independent directors have different ownership–performance incentives. Our results are consistent with this proposition and suggest that independent directors may be immune to the theorised incentive alignment or entrenchment effects associated with share ownership.
