title: Joseph Campbell and his thermo-hyperphoric process

authors: Hart, Philip

abstract: Joseph Campbell was both an Anglican clergyman and a scientist, with a preference for the latter. Actively involved in educating the masses in scientific matters, and particularly those, like miners, with particular problems to overcome, he was a rather shameless self-publicist, insisting that he could solve most things. Sometimes he was correct, and his practical advice was valued, especially in the last phase of his life.
After Alfred Andrew Lockwood developed a method of treating refractory Te Aroha ore, Campbell modified it, naming it the thermo-hyperphoric process. After inspecting Hauraki mines in 1896, he later settled at Te Aroha to test his process on a large scale. Great success was promised, with claims being made that he could save most of the assay value of the ore in a process superior to any other. Other miners along with geologists were critical of his claims and of his understanding of the geology, but he ignored them. The Montezuma Company was formed in London to fund the development of mines mostly between Tui and Te Aroha, and to erect his plant. Despite his promises, his plant failed, to great local disappointment. 
In addition to trialing ore treatment, Campbell also experimented in other areas. After leaving Te Aroha and focusing for a time on being a clergyman, he settled in North Queensland, remaining there until his death trying to solve a variety of problems facing primary producers, sometimes with success. To the end of his life he claimed to be an expert in a myriad of fields, and ignored all his critics.

title: A 250-year periodicity in Southern Hemisphere westerly winds over the last 2600 years

authors: Turney, Chris S.M.

abstract: Middle Holocene cultures have been widely studied around the Eastern-Mediterranean basin in the last 30 years and past cultural activities have been commonly linked with regional climate changes. However, in many cases such linkage is equivocal, in part due to existing climatic evidence that has been derived from areas outside the distribution of ancient settlements, leading to uncertainty from complex spatial heterogeneity in both climate and demography. A few high-resolution well-dated paleoclimate records were recently established using speleothems in the Central and Eastern-Mediterranean basin, however, the scarcity of such records in the western part of the Mediterranean prevents us from correlating past climate evolutions across the basin and deciphering climate–culture relation at fine timescales. Here we report the first decadal-resolved Mid-Holocene climate proxy records from the Western-Mediterranean basin based on the stable carbon and oxygen isotopes analyses of two U/Th dated stalagmites from the Gueldaman GLD1 Cave in Northern Algeria. Comparison of our records with those from Italy and Israel reveals synchronous (multi) centennial dry phases centered at ca. 5600, ca. 5200 and ca. 4200 yr BP across the Mediterranean basin. New calibrated radiocarbon dating constrains reasonably well the age of rich anthropogenic deposits (e.g., faunal remains, pottery, charcoal) excavated inside the cave, which allows the comparison between in situ evidence of human occupation and of climate change. This approach shows that the timing of a prolonged drought at ca. 4400–3800 yr BP blankets the onset of cave abandonment shortly after ca. 4403 cal yr BP, supporting the hypothesis that a climate anomaly may have played a role in this cultural disruption.

title: Behind the label: Complexities of identifying Māori whānau in an away from home hospital transfer

authors: Masters-Awatere, Bridgette

subjects: Māori whānau

abstract: This paper highlights two methodological issues that arose for a group of Māori researchers during the first few months of a Māori CoRE funded project. The issues were in relation to defining 1) the evolving construction of Māori whānau in New Zealand, and 2) an away from home hospital transfer. Through the process of reflexive practice about our knowledge constructs the research team highlight some of the complexities that we as indigenous researchers had to navigate when working within a cultural context. We describe the details of the Hospital Transfers project and reflect on the learning experienced during the pilot interview phase of a three year project.
