Managing strategic challenges in community sector organisations

Like those in other sectors, managers in community-based organisations face an uncertain and challenging future. Research and writing about the community sector (non-government, notjor-profit, or third seclOr) has canvassed a wide range of issues. A selective review of the recent literature reveals the breadth of research interest in the challenges facing community sector managers. While some reflection on the implications for managers of current economic and social policy contexts is crucial for this sector, research effort needs to be focused on understanding how third sector managers construe their current strategic challenges and the strategies they use to address them A small sample ofmanagers working in a regional area in South East Queensland was asked to identify current strategic concerns related to the future viability of their organisations. The key issues raised by managers are compared with the issues raised in the research literature. Results -to date indicate that managers' concerns are reflected in the research literature, but that managers are also concemed about the current trends in social policy towards collaboration, amalgamation, and pannership. Implications of these findings for managers operating in this sector are discussed.

Epizootic activity of Murray Valley encephalitis and Kunjin viruses in an aboriginal community in the Southeast Kimberley region of Western Australia: Results of mosquito fauna and virus isolation studies

We undertook annual surveys of flavivirus virus activity in the community of Billiluna of Western Australia in the southeast Kimberley region between 1989 and 2001. Culex annulirostris was the dominant mosquito species, particularly in years of above average rains and flooding. Murray Valley encephalitis (MVE) virus was isolated in 8 of the 13 years of the study from seven mosquito species, but more than 90% of the isolates were from Cx. annulirostris. The results suggest that MVE virus is epizootic in the region, with activity only apparent in years with average or above average rainfall and increased numbers of Cx. annulirostris. High levels of MVE virus activity and associated human cases were detected only once (in 1993) during the survey period. Activity of MVE virus could only be partially correlated with wet season rainfall and flooding, suggesting that a number of other factors must also be considered to accurately predict MVE virus activity at such communities.

Quality of life assessment in the community-dwelling elderly: Validation of the Assessment of Quality of Life (AQoL) Instrument and comparison with the SF-36

Measurement of Health-Related Quality of Life (HRQoL) of the elderly requires instruments with demonstrated sensitivity, reliability, and validity, particularly with the increasing proportion of older people entering the health care system. This article reports the psychometric properties of the 12-item Assessment of Quality of Life (AQoL) instrument in chronically ill community-dwelling elderly people with an 18-month follow-up. Comparator instruments included the SF-36 and the OARS. Construct validity of the AQoL was strong when examined via factor analysis and convergent and divergent validity against other scales. Receiver Operator Characteristic (ROC) curve analyses and relative efficiency estimates indicated the AQoL is sensitive, responsive, and had the strongest predicative validity for nursing home entry. It was also sensitive to economic prediction over the follow-up. Given these robust psychometric properties and the brevity of the scale, AQoL appears to be a suitable instrument for epidemiologic studies where HRQoL and utility data are required from elderly populations.

Nitrifying microbial community analysis of nitrite accumulating biofilm reactor by fluorescence in situ hybridization

Biological nitrogen removal via nitrite pathway in wastewater treatment is very important especially in the cost of aeration and as an electron donor for denitrification. Wastewater nitrification and nitrite accumulations were carried out in a biofilm reactor. The biofilm reactor showed almost complete nitrification and most of the oxidized ammonium was present as nitrite at the ammonium load of 1.2 kg N/m3/d. Nitrite accumulation was achieved by the selective inhibition of nitrite oxidizers by free ammonia and oxygen limitation. Nitrite oxidation activity was recovered as soon as the inhibition factor was removed. Fluorescence in situ hybridization studies of the nitrite accumulating biofilm system have shown that genus Nitrosomonas which is specifically hybridized with probe NSM 156 was the dominant nitrifying bacteria while Nitrospira was less abundant than those of normal nitrification systems. Further FISH analysis showed that the combinations of Nitrosomonas and Nitrospira cells were identified as important populations of nitrifying bacteria in an autotrophic nitrifying biofilm system.

Cherbourg revisited: hearing health changes in an Aboriginal community, 1972 to 2000

The aim of this study was to investigate current audiological outcomes of Cherbourg schoolchildren and compare these outcomes to those obtained in a 1972 study of hearing health in the same community. Seventy-eight primary school children of Cherbourg State School participated in the study. Their peripheral hearing and middle ear function were tested using pure-tone air conduction audiometry and tympanometry respectively. A significant improvement in the hearing status of this population was noted compared to that reported in 1972. The improvements in the hearing status of Indigenous schoolchildren at Cherbourg can be attributed to a number of factors, including increased awareness of both ear health and general health, as well as the introduction of hearing health care services, over the past three decades.
