Fresh garlic : a possible vehicle for Salmonella Virchow

A sustained increase in Salmonella enterica serovar Virchow notifications in South Eastern Australia between September 1997 and May 1998 instigated a case-control study and environmental investigations. Cases were defined as having locally acquired culture-confirmed S. Virchow phage-type 8 infection and diarrhoeal disease. Matched controls were selected by progressive digit dialling based on cases telephone numbers. An exposure and food history questionnaire was administered by telephone. Phage typing and pulse field gel electrophoresis were performed on case and environmental isolates. Thirty-two notifications of S. Virchow infection met the case definition, 37% reported bloody diarrhoea and S. Virchow was isolated from blood in 13% of cases. Twelve patients were admitted to hospital and one died. Fresh garlic (OR 4·1, 95% CI 1·3-12·8) and semi-dried tomatoes (OR 12·6, 95% CI 1·5-103·1) were associated with these cases. The associations remained significant after adjusting for sex and age. S. Virchow (PT 8) was cultured from two brands of semi-dried tomatoes associated with cases in two different states. We provide sufficient evidence for semi-dried tomatoes and fresh garlic to be considered as potential risk foods in future Salmonella outbreak investigations.

Beyond Abrahamism : a fresh reading of the Tanakh traditions respecting Lot, Moab and Ammon

At the heart of this study is my interest in the way in which a religious community establishes its sense of identity and its boundaries in relation to other groups. I explore the case of Israel's attitude towards her eastern neighbours, the Moabites and Ammonites, as portrayed in Tanakh, the Hebrew Bible. Most commentary from the last one hundred years privileges one particular view of Moab and Ammon as traditional enemies of Israel. I aim to show the validity of readings of the biblical accounts that reveal a more complex relationship between Israel and her neighbours. Tanakh exhibits a dialectic between eirenic and hostile viewpoints. The stories of Abraham and Lot, who are presented as ancestors of Israel and of Moab and Ammon, to some degree represent Israel’s understanding of her neighbours. Conventional commentaries take for granted the accepted orthodoxy of Judaism, Christianity and Islam concerning Abraham and his significance in terms of faith and righteousness and blessing and covenant. As none of these notions is specifically linked to Lot at any point, he is treated as a pathetic figure and remains secondary in conventional commentary. Many commentaries denigrate the character of Lot, often in direct comparisons with Abraham. My reading of the texts of Genesis attempts to free the story of Lot from the constraints imposed by the way the story of Abraham functions. A careful reading of the Genesis account shows that Lot and Abraham exhibit similar elements of moral ambiguity, and Genesis contains no statement that condemns Lot on moral or religious grounds. Genesis 19, the single narrative in which Lot appears independently of Abraham, participates in the dialectic elsewhere in Tanakh. On the basis of a consistent pattern of action and speech throughout the first portion of Genesis 19, I advance my own original conception of the eirenic viewpoint of the narrator concerning Lot and his relationship to the divine. I attempt to demonstrate ways in which the story of Lot critiques or deconstructs the dominant ideology centred upon Abraham. My conception of the particular interests of the compiler of Genesis 19 is supported by several intertextual studies. These include the traditions of Sodom and of Zoar, the story of hospitality in Judges 19, the story of the deluge (Genesis 6-9) and stories of women who, like Lot’s daughters, act to continue the family line. In a treatment of the history of Lot traditions, I find evidence to separate the story of Lot from the work of the Yahwist. I consider whether the stories of Lot have a derivation east of the Jordan and whether the stories were of particular interest to the Deuteronomists. In the final chapter of this study, I focus on the main themes of the narratives concerning Lot and Abraham, and Moab and Ammon and Israel. The question of social boundaries arises in regard to many of these themes, such as the interaction of female and male, the role of wealth, the relation of city and country, kinship, and rights to land settlement. In this way, the treatment of Lot and Abraham in Tanakh and in subsequent traditions offers a perspective upon the formation of identity in the contemporary world of religious plurality.

Do public investments crowd out private investments? Fresh evidence from Fiji

In this paper, we investigate whether government investment crowds out or crowds in private investment for Fiji over the period 1950–2001. We begin by searching endogenously for break points in the data series using the Zivot and Andrews [J. Business Economic Stat. 10 (1992) 251–270] test. Upon finding that 1975 is the statistically significant break date, we divide the sample into two. Using the error correction mechanism test, we find that government and private investments are cointegrated over the period 1950–1975, but not for the period 1976–2001. We also find that in the former period government investment has crowded in private investment, while in the latter period the relationship between government and private investments has been statistically weak.

Who stole the cheese? or : How postmodernism can grow your business

In this paper, I examine some of the key management literature of the neoliberal 1990s to make a series of wider observations about contemporary ideology. Post-structuralist or post-modernist theory is often presented as the arch-enemy of neoliberal capitalism, as the orthodoxy of late capitalism. However, adding to work by Frederic Jameson, Thomas Frank and others, this paper examines uncanny proximity between neoliberal ideas about disaggregating, outsourcing, networking, etc. and the learning motifs of postmodernist theory. Its guiding hypothesis is that postmodernism in the academy, despite its own self-misrecognition as "racial", is a further ideological expression of the samr neoliberal drive to overcome "Fordist", "authoritarian" ways of organising producation and social regulation.

Fresh water: new perspectives on water in Australia

Is water a resource or is it the source? Is it something to be consumed or does it have a life of its own? Recent histories of environmental misunderstanding and exploitation shadow our current regime of water management and use. While governments grapple with how to respond to widespread drought, the situation worsens. There is something amiss in current approaches to water. This timely collection of essays addresses the critical and contentious issue of water in Australia today and suggests a need to radically rethink our relationship with this fundamental substance. Contributors from a range of fields, from anthropology to visual arts, discuss the various ways in which we are caught up with water, and challenge us to take up the cultural transformations that underpin a sustainable ecological future

Effect of cow diet on the composition of milk for cheddar cheese manufacture

Seasonal milk production in Australia has a large impact on the manufacture of cheddar cheese, because the variable milk quality affects cheese moisture content and yield. The influence of cow diet on the composition of milk was investigated together with the effects of variation in milk composition on Cheddar cheese composition and yield. The composition of milk, especially the protein and mineral content, from cows offered diets comprising different energy and protein supplements was correlated with the composition and yield of Cheddar cheese produced.

Development aid : a fresh look

This book addresses a number of gaps in knowledge on aid allocation and effectiveness, and provides many new and important analytical insights into aid. Among the topics covered are the interface between aid allocation and perceptions of aid effectiveness, the inter-recipient concentration of aid from non-govenment organizations, the year-on-year volatility of aid, impacts of aid on public sector fistcal aggregates, and evaluation of the country-level impacts of aid. The book is an essential companion for professionals engaged in aid policy reforms and also for scholars in the areas of development economics, international finance and economics.

Milking their health for all its worth? Improving the health of farming families through facilitated learning

The Victorian Dairy Industry has an annual turnover of $5,125 million and produces over two thirds of the nation’s fresh milk and cheese, but what do we know about the health of the dairy men and women who drive this industry, and how can health professionals and industry assist them to focus on the health of the people involved in the farm business? The Sustainable Dairy Farm Families (SDFF) program undertook research exploring the health, wellbeing and safety of Victorian Dairy farming families across eleven locations. The program involved physical assessments, reviewed health conditions and health behaviours and provided education relating to common health conditions. Risk factors were identified for chronic and lifestyle diseases such as cardiovascular disease, diabetes and cancer. Participants were referred to health professionals as required and reassessed over three years concluding in 2007. The program has influenced participants’ decisions about their health and improved some clinical indicators. A cross-sectoral intervention appears to be an effective method for improving health, wellbeing and safety in farm men and women and their families.

Consumption of foods by young children with diagnosed campylobacter infection : a pilot case-control study

Objective: To determine whether parentally reported habitual intake of specific foods differed between children with diagnosed Campylobacter jejuni infection and children of a comparison group without diagnosed infection.

Design, setting and subjects: Information was collected from the parents or primary caregivers of South Australian children aged 1–5 years with diagnosed C. jejuni (cases, n=172) and an age- and gender-matched group of uninfected children (controls, n=173). Frequency of consumption of 106 food and drink items was determined for the preceding two months by food-frequency questionnaire. Four children in the control group had recorded diarrhoeal episodes during the assessment period and were excluded, so 169 responses were evaluated for this group. Information was gathered on possible confounders including socio-economic status. Response frequencies were classified into three levels of consumption (rarely, weekly or daily) and statistical comparison was made by frequency of consumption of foods versus the ‘rarely’ classification for cases and controls, respectively.

Results: Frequency of consumption of most foods, including starchy foods and fruits and vegetables, did not differ between cases and controls. However, reported consumption of eight food items (block and processed cheese (slices and spread), salami/fritz (a form of processed sausage), chicken nuggets, pasteurised milk, fish (canned or fresh) and hot French fries) was significantly higher by controls.

Conclusions: The hypothesis that reported consumption of starchy foods was lower by cases than by controls was not supported by the data. However, consumption of some processed and unprocessed foods was higher by controls. Some of these foods have established bactericidal actions in vitro that may indicate a possible mechanism for this apparent protection.

A fresh look at the validity of diffusion equations for modelling phosphorescence imaging of biological tissue

Phosphorescence lifetime imaging has become a widely used technique for tomographic oxygen imaging. The conventional model used to characterize photon transport in phosphorescence imaging is two coupled diffusion equations. On the premise that the total energy of excitation and phosphorescence photon flows must be conserved, we derive the diffusion equations in phosphorescence imaging and show that there must be an additional term to account for the transport of phosphorescent photons. This additional term accounts for the transport of phosphorescence photon energy density due to its gradients. The significance of this term in modelling phosphorescence in biological tissue is assessed.

A fresh look at the validity of the diffusion approximation for modeling fluorescence spectroscopy in biological tissue

Fluorescence has become a widely used technique for applications in noninvasive diagnostic tissue spectroscopy. The standard model used for characterizing fluorescence photon transport in biological tissue is based on the diffusion approximation. On the premise that the total energy of excitation and fluorescent photon flows must be conserved, we derive the widely used diffusion equations in fluorescence spectroscopy and show that there must be an additional term to account for the transport of fluorescent photons. The significance of this additional term in modeling fluorescence spectroscopy in biological tissue is assessed.
