Current knowledge of the environmental influences on Australian cashmere production and quality

Goat fibre production is affected to a similar extent by genetic and environmental influences. Environmental influences include bio-geophysical factors (photoperiod, climate-herbage system and soil-plant trace nutrient composition), country of origin, nutrition factors (live weight, growth patterns) and management factors (farm, herd age and sex structure). Nutrition and management influences discussed include rate of stocking, energy nutrition, live weight change, parturition and management during shearing. The nutritional variation within and among years is the most important climatic factor influencing cashmere production, fibre diameter and fibre curvature (crimp). With productive cashmere goats, large responses to energy supplementation have been measured with optimum nutritional management. The effects and importance of management and hygiene during fibre harvesting (shearing) in producing quality fibre are emphasised.

Identifying crucial gaps in our knowledge of the life-history of avian influenza viruses - An Australian perspective

We review our current knowledge of the epidemiology and ecology of avian influenza viruses (AIVs) in Australia in relation to the ecology of their hosts. Understanding the transmission and maintenance of low-pathogenic avian influenza (LPAI) viruses deserves scientific scrutiny because some of these may evolve to a high-pathogenic AIV (HPAI) phenotype. That the HPAI H5N1 has not been detected in Australia is thought to be a result of the low level of migratory connectivity between Asia and Australia. Some AIV strains are endemic to Australia, with Australian birds acting as a reservoir for these viruses. However, given the phylogenetic relationships between Australian and Eurasian strains, both avian migrants and resident birds within the continent must play a role in the ecology and epidemiology of AIVs in Australia. The extent to which individual variation in susceptibility to infection, previous infections, and behavioural changes in response to infection determine AIV epidemiology is little understood. Prevalence of AIVs among Australian avifauna is apparently low but, given their specific ecology and Australian conditions, prevalence may be higher in little-researched species and under specific environmental conditions.

The value of ethnoecological knowledge of the Minahasans: repositioning traditional biocultural knowledge in Indonesian environmental planning

Indonesian strategic and statutory environmental regimes have drawn directly from conventional Western models of environmental planning and natural resource management. These models are often at odds with, do not connect with, nor appreciate generational traditional biocultural knowledge and information from regionally-specific Indigenous communities in Indonesia. This knowledge, and the voice of the custodians of this knowledge, has been overlooked and circumvented in the name of broadscale nationalistic co-ordinated strategic planning. The problem is that nationalist planning, in a multicultural archipelago full of a diverse set of communities often with their own languages, dialects, cultural relationships to landscape, and mixed connectivity to different cohorts of colonial (European and Asian) and religious affiliations means that a deep understanding of environmental information at local and regional level is negated and denied legitimacy. This paper offers a platform to discuss this issue, the difficulty of nationalistic planning and its failings at the Minahasan regional level in Indonesia, and the wealth of cultural and environmental answers the Minahasan culture can bring to the table to better management its landscape sustainably and culturally. This paper’s purpose is to question conventional and generic environmental planning systems in Indonesia and charts an alternate culturally-attuned agenda that can offer to inform and better manage landscapes sustainably and culturally. The tipping points are deep questions about how to regionally manage landscapes sustainably and culturally in deference to a nationalistic agenda before the latter dooms the former producing a 'one-fits all' or generic Indonesian biogeographical landscape devoid of cultural nuances.

The use and misuse of religious language: Zionism and the Palestinians

Every discipline which deals with the land question in Canaan-Palestine- Israel is afflicted by the problem of specialisation. The political scientist and historian usually discuss the issue of land in Israel purely in terms of interethnic and international relations, biblical scholars concentrate on the historical and archaeological question with virtually no reference to ethics, and scholars of human rights usually evade the question of God. What follows is an attempt, through theology and political history, to understand the history of the Israel-Palestine land question in a way which respects the complexity of the question. From a scrutiny of the language used in the Bible to the development of political Zionism from the late 19th century it is possible to see the way in which a secular movement mobilised the figurative language of religion into a literal 'title deed' to the land of Palestine signed by God.

The language of subjective well-being

The Language of Depression project is a linguistic study of the language of Acute Care Hospital patients suffering depression with the ultimate aim of enabling medical and nursing staff to become more aware of their patients’ depression and immediately refer them for psychological or psychiatric help. As part of that larger project, and following recent developments in positive psychology (e.g. Seligman 2002) this paper will focus exclusively on the control group, that is, the language of those Acute Care Hospital patients deemed non-depressed. The data comprise 30 minute interviews between the patients and a Consultation-liaison psychiatrist. Prior to interview, the patients were screened using the Brief Case-find for Depression (Clarke et al. 1994). From the screening, patients were then deemed likely to be depressed and likely to be non-depressed. This paper reports on the analysis of 10 patients deemed as non-depressed. Using the linguistic theory of Systemic Functional Linguistics, the data were analysed for their Appraisal features (e.g. Martin and Rose 2003). Appraisal analysis provides a lexico-semantic analysis that is concerned with how speakers use language to evaluate as well as negotiate relationships. The Appraisal analysis has been used to identify in the language of non-depressed patients the types of attitudes that facilitate psychological well-being. This paper will present some analysed extracts from the interviews to show how key features of subjective well-being are realised in the language of non-depressed Acute Care Hospital patients.

Patient assessment of medication information leaflets and validation of the Evaluative Linguistic Framework (ELF)

Objective : To obtain patient feedback about the structure and quality of medication information leaflets and validate the usefulness of the Evaluative Linguistic Framework (ELF) for improving written communication with patients.
Methods : Triangulated feedback about a set of rheumatoid arthritis (RA) medication leaflets, some developed with knowledge of the ELF, was obtained from 27 people with RA from interviews, focus group discussion and self-administered questionnaires. The principal elements of the framework were investigated: overall generic structure and functions of each stage, interpersonal relationship between writer and reader, technicality of language and density of information.
Results : Participant assessments of the leaflets aligned with the framework in terms of what constituted a good leaflet. While the main purpose of the leaflets was identified as being information provision, participants also wanted clear instructions, benefits to be highlighted and side effects to be comprehensively listed. For comprehensiveness and user-friendliness, leaflets developed with guidance of the ELF were consistently preferred.
Conclusion : According to people with RA, leaflets generated from a linguistic framework are clearer and more effective in communicating information about medications.
Practice Implications : The ELF is a user-friendly, structured analytic system that can assist with the development of effective high quality patient information materials.

Knowledge of human papillomavirus (HPV) and the HPV vaccine in a national sample of Australian men and women

Background: Human papillomavirus (HPV) knowledge has rarely been investigated in the context of a national vaccination program. The present study investigated HPV knowledge after the introduction of a national HPV vaccination program in Australia using a national sample of men and women. Methods: Questions assessing HPV knowledge were part of a broader national study of health and relationships administered via a computer-assisted telephone interview. These findings are from wave four of the study, conducted between 2007 and 2008. Knowledge questions about HPV included its association with cervical cancer, genital warts and abnormal Pap tests. Results: A total of 2634 women and 2556 men between the ages of 18 and 70 were interviewed. Overall, 62.8% (95% confidence interval (CI): 60.8–64.7%) of women and 38.3% (95% CI: 36.3–40.4%) of men had heard of HPV. Of these, 66.0% (95% CI: 64.1–67.9%) correctly answered that HPV is associated with cervical cancer, 50.2% (95% CI: 48.2–52.1%) answered that HPV is associated with abnormal Pap tests and 44.5% (95% CI:42.5–46.5%) answered that HPV causes warts. Predictors of good knowledge included being female, aged between 26 and 45, holding higher education levels and older age at first sex. Ever having a Pap test was also associated with awareness about HPV. Conclusion: One of the highest levels of knowledge about HPV in Australia to date is reported in the present study. Knowledge about the association between HPV and cervical cancer was particularly high, especially when compared with knowledge of the association with genital warts. This appears to be a consequence of the marketing of the HPV vaccine as a vaccination against cervical cancer.

Stakeholder knowledge of threatened coastal species; the case of beach-goers and the Hooded Plover Thinornis rubricollis

One way of measuring pre-existing knowledge of a threatened species and its circumstances is to measure the degree of surprise expressed by stakeholders in relation to factual statements regarding the species. Beach-goers (n = 684) were surveyed in regard to their knowledge of the beach-dwelling, threatened, Hooded Plover Thinornis rubricollis, a coastal obligate in south eastern Australia. Principle components analysis revealed that respondents’ degree of knowledge could be categorized as involving ‘chick (flightless young) ecology’ and ‘human impacts’ (threatening processes). Respondents were more surprised by aspects of chick ecology than by threatening processes (F1,514 = 460.446, p < 0.001). Prior knowledge of the species was associated with less surprise at factual statements. Therefore, priorities for further education should focus on linking threats with chick ecology, particularly because an understanding that chicks are not stationary within fenced areas is critical to the interpretation and effectiveness of current signage used to mitigate human impacts.

Floodplain wetlands of the Gellibrand estuary: What type of invertebrate community

Introduction. Along the south coast of Australia, wetlands on the floodplains of lowland rivers and estuaries have been severely altered by agriculture and urbanization. Efforts to restore or rehabilitate these wetlands are hampered by insufficient knowledge of the original condition of these wetlands, or their variability in time and space. This research describes the macroinvertebrate community of wetlands on the floodplain of the Gellibrand River and estuary, which has suffered comparatively few human impacts. The aim of the research was to describe the variability of macroinvertebrate communities as a baseline for the future management of these wetlands, and to contribute to the general understanding of estuary-floodplain wetlands, thereby improving the basis for their management.

The Gellibrand River has a catchment area of approximately 1200 km2 draining the western slopes of the Otway Ranges, and entering the Southern Ocean at Princetown. From a mean annual flow of 315 000 mL, 25 000 mL are removed per annum for agricultural and domestic use (O'May & Wallace 2001), and flows are closer to natural regimes than most other Western Victorian rivers. The estuary is a bar-built, salt-wedge estuary that becomes completely blocked by the sand bar in most years, during summer and autumn. Over past decades, the estuary mouth has been opened artificially in most years. to prevent flooding of agricultural land and roads adjacent to the wetlands. At its maximum, the salt-wedge penetrates approximately 10 km upstream from the river mouth, but the estuary may also be completely fresh during high winter discharge
(Mckay 2000).

The wetlands surrounding Princetown cover 119 ha and are listed as nationally important (Environment Australia 2001). This listing regards the wetlands as an important habitat for animals at vulnerable stages of their life cycle and a refuge from adverse conditions, such as drought. They are a good example of coastal brackish and freshwater marshes, with an important ecological and hydrological role as part of a large wetland
complex.

Distribution and habitat requirements of the Yellow-Footed Antechinus Antechinus flavipes at multiple scales: a review

This review synthesises present knowledge of the distribution patterns and habitat requirements of the Yellow-footed Antechinus Antechinus flavipes. Factors influencing the distribution of A. flavipes are examined at several spatial scales ranging from the broad climatic conditions prevalent over the species’ entire range to the characteristics of nest sites used by individual animals. Analysis of the literature suggests that: 1) at the broad-scale, A. flavipes distribution is largely determined by warm, dry climatic conditions, the distribution of dry forests and woodlands and competition with closely related species; 2) at the landscape-scale the determinants of A. flavipes distribution are largely unknown, although initial investigations suggest some tolerance of fragmented landscapes; and 3) at a local-scale the distribution of A. flavipes is largely determined by the presence of large diameter trees, tree hollows, coarse woody debris, rocky crevices and leaf-litter. Directions for future research are suggested throughout the review.

Adoption of the world wide web by traditional Australian media organisations

The aim of this paper is it to identify whether Australian media companies moved online with a clear business model in mind or in an ad-hoc manner. In-depth interviews were conducted with four Internet media managers from two large Australian media organisations. All four had been involved in Web publishing from its early stages and had extensive knowledge of the development of Web publishing in the industry. The interviews focused on the period around the mid 1990’s when the early development of the organisations’ websites took place. We also review an analytical approach of examining narratives from research interviews developed by Davidson (Davidson 1997) and Mishler (Mishler1986a, 1986b).

Foraging behaviour and habitat selection of the little penguin Eudyptula minor during early chick rearing in Bass Strait, Australia

Knowledge of the foraging areas of top marine predators and the factors influencing them is central to understanding how their populations respond to environmental variability. While there is a large body of literature documenting the association of air-breathing marine vertebrates with areas of high marine productivity, there is relatively little information for species restricted to near-shore or continental-shelf areas. Differences in foraging range and diving behaviour of the little penguin Eudyptula minor were examined from 3 breeding colonies (Rabbit Island, Kanowna Island and Phillip Island) in central northern Bass Strait, southeast Australia, during the chick-guard stage using electronic tags (platform terminal transmitters, PTTs, and time-depth recorders, TDRs). Although there were large overall differences between individuals, the mean maximum foraging range (16.9 to 19.8 km) and mean total distance travelled (41.8 to 48.0 km) were similar between the 3 colonies, despite different bathymetric environments. Individuals from all 3 colonies selected foraging habitats within a narrow sea surface temperature (SST) range (16.0 to 16.4°C). While there were significant differences in mean dive depths (5.4 to 10.9 m) and mean durations (13.2 to 28.6 s) between the different colonies, the mean diving effort (vertical distance travelled: 936.3 to 964.3 m h–1) was similar. These findings suggest little penguins from the 3 colonies employ relatively similar foraging efforts yet are plastic in their foraging behaviours.
