"I tell ya who needs educatin’”: non-Indigenous cultural self-awareness and prisoner education.

Glen says, “current education is colonial; it ain’t ours. I tell ya who needs educatin’, wadjellas”. Glen is a Noongar man who, along with several other Aboriginal adults living in Western Australia, teaches me in a PhD research project about prisoner education from their perspective. His words pose a question for wadjellas like myself who are raised, taught and work in a white neo-colonial society. We have been raised in, taught in and work in a colonial system. As non-Aboriginal people we have unearned privileges which are often invisible and unacknowledged. How then to address the outcomes of this in a way that might lead to working co-operatively alongside Aboriginal people? What kind of ‘educatin’ could teach us about our own unacknowledged privilege and the disadvantage this can lead to for others? Is the standard cross-cultural awareness training enough?This paper shares some of the teachings of Glen and other participants in this research. It expresses the view that, ultimately, the usually unacknowledged legacy of colonisation and associated issue of denied Aboriginal sovereignty lies at the heart of much of the disadvantage experienced by Aboriginal people today when considering education and the prison system. Addressing gaps in non-Indigenous cultural self-awareness by learning from Aboriginal people is an important factor in improving their experiences of education.

Interview with Samson Akunaii

Samson Akunaii is a Papua New Guinean who studied in Australia at James Cook University in Townsville, Queensland 1987-1989. He was awarded an AusAID scholarship through his employer the PNG Institute of Medical Research (IMR) and completed an MBA. His wife and three daughters accompanied him to Australia. He returned to Goroka in PNG and currently works in Corporate Affairs for the IMR. The interview was conducted by Dr Jonathan Ritchie of Deakin University and Dr Musawe Sinebare of Pacific Adventist University. The interview was recorded on 9 July 2014. This set comprises: An interview recording, timed summary of the interview, and photograph of Samson Akunaii.

Screening bacterial metabolites for inhibitory effects against Batrachochytrium dendrobatidis using a spectrophotometric assay

Certain bacteria present on frog skin can prevent infection by the pathogenic fungus Batrachochytrium dendrobatidis (Bd), conferring disease resistance. Previous studies have used agar-based in vitro challenge assays to screen bacteria for Bd-inhibitory activity and to identify candidates for bacterial supplementation trials. However, agar-based assays can be difficult to set up and to replicate reliably. To overcome these difficulties, we developed a semi-quantitative spectrophotometric challenge assay technique. Cell-free supernatants were prepared from filtered bacterial cultures and added to 96-well plates in replicated wells containing Bd zoospores suspended in tryptone-gelatin hydrolysate-lactose (TGhL) broth medium. Plates were then read daily on a spectrophotometer until positive controls reached maximum growth in order to determine growth curves for Bd. We tested the technique by screening skin bacteria from the Australian green-eyed tree frog Litoria serrata. Of bacteria tested, 31% showed some degree of Bd inhibition, while some may have promoted Bd growth, a previously unknown effect. Our cell-free supernatant challenge assay technique is an effective in vitro method for screening bacterial isolates for strong Bd-inhibitory activity. It contributes to the expanding field of bioaugmentation research, which could play a significant role in mitigating the effects of chytridiomycosis on amphibians around the world.

Seagrass and associated benthic community data derived from field surveys at Low Isles, Great Barrier Reef, conducted July-August, 1997

The distribution of seagrass and associated benthic communities on the reef and lagoon of Low Isles, Great Barrier Reef, was mapped between the 29 July and 29 August 1997. For this survey, observers walked or free-dived at survey points positioned approximately 50 m apart along a series of transects. Visual estimates of above-ground seagrass biomass and % cover of each benthos and substrate type were recorded at each survey point. A differential handheld global positioning system (GPS) was used to locate each survey point (accuracy ±3m). A total of 349 benthic survey points were examined. To assist with mapping meadow/habitat type boundaries, an additional 177 field points were assessed and a georeferenced 1:12,000 aerial photograph (26th August 1997) was used as a secondary source of information. Bathymetric data (elevation below Mean Sea Level) measured at each point assessed and from Ellison (1997) supplemented information used to determine boundaries, particularly in the subtidal lagoon. 127.8 ±29.6 hectares was mapped. Seagrass and associated benthic community data was derived by haphazardly placing 3 quadrats (0.25m**2) at each survey point. Seagrass above ground biomass (standing crop, grams dry weight (g DW m**-2)) was determined within each quadrat using a non-destructive visual estimates of biomass technique and the seagrass species present identified. In addition, the cover of all benthos was measured within each of the 3 quadrats using a systematic 5 point method. For each quadrat, frequency of occurrence for each benthic category was converted to a percentage of the total number of points (5 per quadrat). Data are presented as the average of the 3 quadrats at each point. Polygons of discrete seagrass meadow/habitat type boundaries were created using the on-screen digitising functions of ArcGIS (ESRI Inc.), differentiated on the basis of colour, texture, and the geomorphic and geographical context. The resulting seagrass and benthic cover data of each survey point and for each seagrass meadow/habitat type was linked to GPS coordinates, saved as an ArcMap point and polygon shapefile, respectively, and projected to Universal Transverse Mercator WGS84 Zone 55 South.
