Australian Aboriginal Ethnometeorology and Seasonal Calendars

This paper uses a cultural anthropological approach to investigate an indigenous Australian perspective on atmospheric phenomena and seasons, using data gained from historical records and ethnographic fieldwork. Aboriginal people believe that the forces driving the weather are derived from Creation Ancestors and spirits, asserting that short term changes are produced through ritual. By recognizing signals such as wind direction, rainfall, temperature change, celestial movements, animal behaviour and the flowering of plants, Aboriginal people are able to divide the year into seasons. Indigenous calendars vary widely across Australia and reflect annual changes within Aboriginal lifestyles

Changes in causes of acute gastroenteritis in the United Kingdom over 15 years: microbiologic findings from 2 prospective, population-based studies of infectious intestinal disease.

BACKGROUND: Large-scale, prospective studies of infectious intestinal disease (IID) in developed countries are uncommon. Two studies of IID incidence and etiology have been conducted in the United Kingdom: the Infectious Intestinal Disease Study in England (IID1) in 1993-1996 and the Second Study of Infectious Intestinal Disease in the Community (IID2) in 2008-2009. We examined changes in etiology and diagnostic yield of IID cases over 15 years. METHODS: Fecal samples submitted by IID cases were examined for a range of bacterial, viral, and protozoal pathogens using traditional and molecular microbiological methods. We calculated the percentage of specimens positive for each organism based on traditional methods and on traditional and molecular methods combined. We compared the distributions of organisms in the 2 studies. RESULTS: For pathogens investigated in both studies, 40% of fecal samples submitted by cases in IID2 were positive compared with 28% in IID1. Viruses were most frequent among community cases in IID2. Campylobacter was the most common bacterial pathogen among cases presenting to healthcare. Major differences between the 2 studies were increases in the detection of norovirus and sapovirus and a decline Salmonella. CONCLUSIONS: Most fecal specimens were negative for the pathogens tested in both studies, so new strategies are needed to close the diagnostic gap. Among known pathogens, effective control of norovirus, rotavirus, and Campylobacter remain high priorities. The reduction in nontyphoidal salmonellosis demonstrates the success of Europe-wide control strategies, notably an industry-led Salmonella control program in poultry in the United Kingdom

A review of early Indigenous artefacts incorporating bird materials in the Lower Murray River region, South Australia

This paper is a literature review of the use of birds in the Indigenous material culture of the Lower Murray River region in temperate South Australia, as observed in the early years of British colonisation. This record is augmented with additional data from fieldwork in the 1980s and early 1990s. It was found that Aboriginal people in this region made artefacts incorporating avian materials based upon their perceived physical and cultural properties. Analysis of material culture with respect to birds contributes to the understanding of Aboriginal use and perception of the Australian landscape. © 2018 Royal Society of South Australia
