  • Detection and Epidemiology of Coxiella Burnetii Infection in Beef Cattle in Northern Australia and the Potential Risk to Public Health
    Detection and epidemiology of Coxiella burnetii infection in beef cattle in northern Australia and the potential risk to public health Caitlin Medhbh Wood BVSc (Hons1) MANZCVS (Veterinary Epidemiology) https://orcid.org/0000-0003-2716-0402 A thesis submitted for the degree of Doctor of Philosophy at The University of Queensland in 2020 School of Veterinary Science Abstract Q fever has a longstanding history in Queensland, Australia. Although it is not a new disease to Australia, Q fever continues to burden the country with some of the highest annual case notification rates globally (Tozer 2015). While there are undeniable links with Q fever cases and exposure to cattle, it appears that coxiellosis predominantly goes undiagnosed and unnoticed in cattle within Australia. Knowledge of the prevalence and distribution of coxiellosis in cattle populations across northern Australia is limited due to minimal surveillance and no standardisation of diagnostic test methods. The overall aim of this PhD project was to improve the understanding of the epidemiology of coxiellosis in beef cattle in northern Australia and gain insights into the potential risk to public health. Descriptive analyses of 2,838 human Q fever notifications from Queensland between 2003 and 2017 were initially reported. Queensland accounted for 43% of the Australian national Q fever notifications for this period. From 2013–2017 the most common identifiable occupational group was agricultural/farming. For the same period, at-risk environmental exposures were identified in 82% (961/1,170) of notifications; at-risk animal-related exposures were identified in 52% (612/1,170) of notifications; abattoir exposure was identified in 7% of notifications.

  • How Warumungu People Express New Concepts Jane Simpson Tennant
    How Warumungu people express new concepts Jane Simpson Tennant Creek 16/10/85 [This paper appeared in a lamentedly defunct journal: Simpson, Jane. 1985. How Warumungu people express new concepts. Language in Central Australia 4:12-25.] I. Introduction Warumungu is a language spoken around Tennant Creek (1). It is spoken at Rockhampton Downs and Alroy Downs in the east, as far north as Elliott, and as far south as Ali Curung. Neighbouring languages include Alyawarra, Kaytej, Jingili, Mudbura, Wakaya, Wampaya, Warlmanpa and Warlpiri. In the past, many of these groups met together for ceremonies and trade. There were also marriages between people of different language groups. People were promised to 'close family' from close countries. Many children would grow up with parents who could speak different languages. This still happens, and therefore many people are multi-lingual - they speak several languages. This often results in multi-lingual conversation. Sometimes one person will carry on their side of the conversation in Warumungu, while the other person talks only in Warlmanpa. Other times a person will use English, Warumungu, Alyawarra, Warlmanpa, and Warlpiri in a conversation, especially if different people take part in it. The close contact between speakers of different languages shows in shared words. For example, many words for family-terms are shared by different languages. As Valda Napururla Shannon points out, Eastern Warlpiri ("wakirti" Warlpiri (1)) shares words with its neighbours, Warumungu and Warlmanpa, while Western Warlpiri shares words with its neighbours. Pintupi, Gurindji, Anmatyerre etc. In Eastern Warlpiri, Warlmanpa and Warumungu the word "kangkuya" is used for 'father's father' (or 'father's father's brother' or 'father's father's sister').

Churchill Arachnology, Queensland Museum, PO Box 3300. South Brisbane, Qld 4101, Australia Centre, PMB 44 present address : Division of Wildlife and Ecology, CSIRO Tropical Ecosystems Research Winnellie, NT 0821, Australia Abstract Churchill, T.B., 1997. Spiders as ecological indicators: an overview for Australia. Memoirs of the Museum of Victoria 56(2): 331-337. Spiders operate as a dominant predator complex which can influence the structure of terrestrial invertebrate communities. The potential use of spiders as indicators of ecological to change, amongst a suite of selected taxa, is worthy of further research. Indicator taxa need be diverse and abundant, readily sampled, functionally significant, and to interact with their the environment in a way that can reflect aspects of ecological change. This paper examines proposes attributes of spiders in terms of these criteria, with an Australian perspective, and the use of families as functional groups to represent divergent foraging strategies and selec- "taxonomic tion of prey types. With such information gain, and reduced impact of the collation of impediment", the cost-benefit of surveys is enhanced to encourage the wider quantitative spider data for management or conservation purposes. Introduction mining (Majer, 1983; Andersen, 1990, ms.). To gain a wider understanding of patterns of biod- iversity and ecological change in invertebrate have an important role to play in Invertebrates communities, however, a range of taxa need to achieving effective conservation and manage- be adopted (Beattieetal., 1993; Kitching, 1994; ment of biodiversity for three reasons: New, 1995; Noss, 1990).

Trejo Department of Economics University of Texas Austin, TX 78712 [email protected] March 2004 How do international differences in labor market institutions affect the nature of immigrant earnings assimilation? Using 1980/81 and 1990/91 cross-sections of census data from Australia, Canada, and the United States, we estimate the separate effects of arrival cohort and duration of destination-country residence on immigrant outcomes in each country. Relatively inflexible wages and generous unemployment insurance in Australia suggest that immigrants there might improve themselves primarily through employment gains rather than wage growth, and we find empirically that employment gains explain all of the labor market progress experienced by Australian immigrants. Wages are less rigid in Canada and the United States than in Australia, with the general consensus that the U.S. labor market is the most flexible of the three. We find that wage assimilation is an important source of immigrant earnings growth in both Canada and the United States, but the magnitude of wage assimilation is substantially larger in the United States.

  • Paul Keating Wheeler Centre
    Conversation between Robert Manne and Paul Keating Wheeler Centre Robert Manne Well, thank you very much … [laughter] Paul Keating I knew I was with a popular guy Robert. Robert Manne I’ll speak about what’s just happened towards the end of today. I have to say, we’ve just heard four musicians from the Australian National Academy of Music, performing Wolf’s Italian Serenade. On violins we had Edwina George and Simone Linley Slattery, on viola Laura Curotta and cello Anna Orzech. The reason we heard them was the Australian National Academy of Music was born out of the vision of Paul Keating, its creation being a major component of his government’s 1994 Creative Nation Policy. [applause] Paul I have to say it is my greatest pleasure and privilege to be invited to do this. Paul Keating Thank you Robert. Robert Manne I hope by the end of my questions, the reason for me saying that will be clear. But anyhow, it’s from the bottom of my heart. Paul Keating Thank you for doing it. You are the best one to do it. [laughter] Robert Manne But I’m going to make sure that it’s not entirely comfortable for either of us, so we want to have a rough and tumble time as well. The reason for this conversation is that Paul Keating has produced what I think is a highly agreeable, highly stimulating and I think vividly and beautifully written book and I recommend it to you. It’s a book with a lot in it, a lot in it, just things that struck me, which I won’t be questioning Paul about, but things that struck me – there is for example an extremely moving eulogy for the musical genius Geoffrey Tozer.
