Polycyclic aromatic hydrocarbon emission loads and profiles from the burning of locally grown wood species in Victoria, Australia - Some pilot project results

A testing facility for combustion of biomass and sampling of emissions has been established at Deakin University. In this pilot project using this facility, four kinds of locally grown wood species were burned and the particle emissions sampled and analysed for Polycyclic Aromatic Hydrocarbons (PAHs). The selected wood species covering pine, red gum, yellow box and sugar gum, are the most popular domestic fuel wood in Australia. Particulate matter emissions from burning of each load of wood were sampled from the flue using a standard stack emission sampling train. The particle-laden filters were extracted and the .extract analysed to determine PAH concentrations by Gas Chromatographyl Mass Spectrometer (Gc/MS). The sampling was conducted under two different burning conditions with the air inlet of the combustion chamber fully open and with it half open. A suite of 15 PAHs, ranging from naphthalene (C IOHB) to dibenzolahlanthracene (C12H14), were selected for analysis. PAH profiles for the four wood species, under the different burning regimes, have been generated. Some preliminary emission factors for the different wood species have been derived as microgram of summed PAHs (rPAHs) emittedlkilogram of wood burned. Total Particulate Matter (TPM) emission factors were also obtained from gravimetric measurement of the sample filter before and after the combustion. Based on these emission factors, pine displayed the highest level of rPAHs emitted from the combustion of the four wood species, with sugar gum showing the lowest level of rPAHs emission. Emission factors associated with the slow burning condition clearly showed higher l:PAH levels compared to the faster burning condition. During the faster burning condition, red gum and pine show a higher percentage of rPAH to TPM than sugar gum or yellow box. Under the slower burning. the l:PAHlTPM ratio in every case was greater.

Corporate liability for workplace deaths and injuries-reflecting on Victoria's laws in the light of the Esso Longford explosion

The purpose of this article is to consider some different legal models for the liability of corporations for the deaths and serious injuries of their employees, with particular emphasis on the law in Victoria.

Two recent developments in Victoria prompt this consideration. First, on 30 July 2001, the Victorian Supreme Court handed down its sentencing decision in the case arising from the explosion on 25 September 1998 at the Longford gas plant operated by Esso Australia Pty Ltd. The decision marked the end of the formal public consideration of a devastating event in Victorian industrial history, which began with the Royal Commission set up on 20 October 1998 to investigate the causes of an explosion in which two workers died and eight others were injured. Second, in early 2002, the Victorian Government failed in its attempt to introduce new criminal offences for corporate employers whose employees are killed or seriously injured at work. In spite of their failure to be passed by the Legislative Council in Victoria, these proposals warrant consideration. They represent a growing trend by policy makers in attempting to address more effectively the question of the liability for deaths and serious injuries of workers to employers who operate through the corporate form.

School health policies and practices in Victoria- a comparison involving socio-economic status

Issue addressed: Health programs have been part of the responsibility of Victorian school education for 90 years. Yet rarely have there been studies to identify what is happening in school health promotion, or what the differences between schools might be, particularly in relation to the socioeconomic status of the school community and whether the school is in a metropolitan or regional area. Methods: In 1997 all Victorian schools (primary and secondary) in the State, Catholic and Independent systems were sent questionnaires in order to promote broader awareness about health promotion, and to identify what health programs, policies and activities the schools believed existed within their school community. A response rate of 43% was achieved, and results were collated under the six domains of the Health Promoting School model as outlined by the Western Pacific Regional Office of the World Health Organisation. Data analysed in this paper compared highest versus lowest quartiles for socioeconomic status (SES), and schools in metropolitan Melbourne versus regional areas. Results: Most differences between schools based on socioeconomic status occurred in secondary schools and were related mainly to environmental policies and practices, use of back packs, the presence of safety policies, involvement of parents in school activities and the provision of services for mental and social health needs. All differences were in favour of the highest SES quartile schools. Environmental policies and procedures, and school-based health and welfare services were present more often in metropolitan schools than in regional and rural schools. Conclusion: Although there were notable differences between schools, the audit results pointed to more similarities than differences between schools in the highest and lowest SES quartiles for health-related policies and practices; there were even fewer differences between metropolitan and non-metropolitan schools. So what: Regardless of the actual advantages and disadvantages schools experience with respect to location or socioeconomic status, it is important to understand that school staff perceive that they can and do have reasonably comprehensive health policies, procedures and practices to address health issues. Nevertheless, clear differences between schools did emerge in certain health areas and findings will assist policy making and the allocation of limited resources.

Dietary items of the black falcon falco subniger and zebra finch taeniopygia guttata in Northern Victoria

This note reports an incidental observation of a Black Falcon Falco subniger taking a Zebra Finch Taeniopygia guttata. The captured Finch voided the contents of its crop, revealing that it had been feeding on Onion Grass Romulea rosea. Zebra Finches have not been reported in the diet of Black Falcons, and Onion Grass seeds have not been reported in the diet of Zebra Finches previously.

Public and stakeholder values of wildlife in Victoria, Australia

This paper explores the management implications of a recent study that was designed to explore public and stakeholder values of wildlife in Victoria, Australia. Questionnaires (n = 1431) were used to examine values and knowledge of wildlife held by residents from seven Victorian municipalities and members of six wildlife management stakeholder groups. The results suggest that most Victorians have a relatively strong emotional attachment to individual animals (the humanistic value) and are interested in learning about wildlife and the natural environment (the curiosity/learning/interacting value). In comparison, the negativistic, aesthetic, utilitarian-habitat and dominionistic/wildlife-consumption values were not expressed as strongly. These findings suggest that wildlife managers should expect support for wildlife management objectives that reflect the relatively strong humanistic orientation of Victorians and tailor management and education programs to appeal to this value and Victorians' interest in learning about wildlife.

Floristic and structural characteristics of a coastal heathland exhibiting symptoms of Phytophthora cinnamomi infestation in the eastern Otway Ranges, Victoria

The floristics and structure of heathland vegetation exhibiting symptoms of Phytophthora cinnamomi Rands infestation was assessed at two sites in heathlands at Anglesea, Victoria. There were significant effects in both floristics and structure. Thirteen heathland species were significantly less abundant in diseased areas and 23 species were more abundant. Diseased (infested) vegetation, when compared with non-diseased areas, had less cover of Xanthorrhoea australis and shrub species and a greater cover of sedges, grasses and open ground. Structural differences were observed between heights 0 and 0.6 m, with a decline in cover recorded in diseased vegetation. Non-metric multidimensional scaling ordination of the floristic data showed a clear separation of diseased and non-diseased vegetation and that changes in floristic composition post-infestation were similar at both sites. Although there was some evidence of regeneration of X. australis, the recovery capacity of other susceptible species at Anglesea is unknown. The long-term consequences of loss of species and structure in the eastern Otways mean that the vegetation is unlikely to return to former status, especially if the pathogen continues to reinfect.

Volunteering and social capital in regional Victoria

The link between volunteerism and social capital has received some attention in Australia in recent years. Of particular note to this paper is the work of Baum, Bush, Modra, Murray, Cox, Alexander, and Potter (2000), who described the contribution volunteers made to social capital in a metropolitan setting - the western suburbs of Adelaide, South Australia. The aim of this current study is twofold, to describe the contribution volunteers make to social capital through participation, reciprocity and social trust in a regional and rural setting; and to compare findings with those relating to a metropolitan environment. In the light of differing volunteer patterns in rural and regional environments compared to metropolitan environments, we hypothesised that the relationship between volunteerism and indicators of social capital would also be different. The results from this study support the findings of Baum, Modra, Bush, Cox, Cooke, and Potter (1999) and therefore reinforce the premise that volunteers make a substantial. contribution to social capital. While greater numbers of people who live in rural or regional areas undertake volunteer work, we found there are more similarities between the rural/regional and metropolitan sectors regarding volunteerism than there are differences.

Rural women and local economic development in south-west Victoria

In the 1990s, the appearance of women in leadership roles in local economic development organisations in small south-west Victorian towns heralded a change in gender relations in rural Australia. This paper contributes to an understanding of this process by investigating the actions and motives of women in leadership roles in small rural towns in south-west Victoria. The paper begins by establishing a framework of analysis based upon a notion of ‘paradigms in progress’. The argument is that in an increasingly interconnected world broader economic, social and political concerns encroach upon local cultures. In this process, older social paradigms or popularly accepted models for how the world works are either transformed, discarded or replaced on different levels. The different levels to which this paper refers are the macromodels of patriarchy, the mesomodels of economic development and the micromodels of leadership. It is the way that these levels intersect and how they are being changed that informs the explanation of women and leadership in south-west Victoria. The paper applies this framework to an analysis of interviews with 15 women in small towns in south-west Victoria. The paper concludes that women in the south-west have been able both to feminise the politics of local economic development as well as reposition the feminine in local social discourses.

Birds of remnant vegetation on the Mornington Peninsula, Victoria, Australia: the role of interiors, edges and roadsides

Habitat loss and fragmentation on the Mornington Peninsula, Victoria, Australia, has resulted in a mosaic of forest patches, forest edges abutted by agricultural land and linear habitat strips amidst a human-modified land matrix. To examine the use of forest elements by the avifauna in this landscape, bird populations were sampled along fixed transects established within forest interiors, on forest edges and along forested roadsides. A total of 60 species was recorded during this study, five of which were introduced. Species richness and diversity did not differ significantly between the three habitat elements, but avifaunal composition varied considerably. The species assemblages of all habitat elements differed significantly, with forest interiors and roadsides showing the greatest difference and forest interiors and forest edges showing the least degree of difference. Forest-dependent bird species used both interiors and edges. Interiors differed from edges and roadsides in having lower abundances of open country species, predatory species and introduced species. A clear gradient of change in bird communities from forest interiors to roadside vegetation was observed. This study suggests that the interiors of medium-sized (<1 000 ha) patches may play an important role in conserving bird biodiversity on a local level as they provide refuge for forest-dependent native species in extensively cleared landscapes.

Consumer satisfaction and post-purchase intentions: an exploratory study of museum visitors

This paper examines the relationship between consumer satisfaction and subsequent intentions in the museum context, as well as the moderating influence of demographic characteristics such as gender, age and education in that relationship. The relationship between satisfaction and a range of service elements, overall satisfaction with the experience and intentions was investigated. Museum marketers can profit by examining the "value chain" of museum experience outlined in the model presented, especially the greater likelihood of consumers recommending the experience to others than making a repeat visit themselves, and by investigating segment differences beyond those reported here.

An integrated study of the temporal and spatial variation in the supply of propagules, recruitment and assemblages of intertidal macroalgae on a wave-exposed rocky coast, Victoria, Australia

Recruitment is known to influence distributions and abundances of benthic marine organisms. It is therefore important to document patterns of variability in recruitment and how these relate to patterns in established assemblages. This study provides an integrated assessment of the temporal and spatial variation in supply and recruitment of propagules and established populations of several macroalgae. Propagules in water samples from two stages of the incoming tide, recruitment to artificial substrata and percentage cover of species established on the shore were recorded every 2 months from December 1994 to October 1995, in two zones of an intertidal, wave-exposed rocky shore. Variability in recruitment was measured at three spatial scales: 10s cm, 100s cm and 100s m. Availability and recruitment of most taxa were greatest between April and August, although many species had available propagules and recruited throughout the year. Temporal variation in the established assemblages was, however, more species-specific. Differences in established assemblages between zones were reflected in differences in availability and recruitment of propagules between zones. Recruitment could not be predicted directly from supply of propagules, but the two processes were linked. For most species, the greatest variation in recruitment occurred at the smallest spatial scale of 10s cm, although there was also considerable large-scale (between site) variation in recruitment of several species. Results indicate that while pre-and post-settlement mortality are likely to influence macroalgal distribution and abundance, the temporal and spatial variability in supply and recruitment of propagules can explain much of the patchiness in macroalgal assemblages.
