Political preferences in the new middle class: A ‘correspondence analysis’ of the orientations of Australian professional workers

Most discussions of the relationship between class and political orientation assume a coherent and homogeneous class response. Here, the new middle class of professional workers is disassembled into constituent occupations. An analysis of political preference data by means of ‘correspondence analysis’ reveals a pattern which is consistent with a structural relationship between occupational experience and political preference.     

Geochemical evidence for the manufacture,logistics and supply‐chain management of Emperor Qin Shihuang's Terracotta Army,China

Non‐invasive materials characterisation of reconstructed statues of Emperor Qin Shihuang's Terracotta Army has revealed distinct micro‐geochemical patterning within the clay paste used in their manufacture. The significance of this is explored in terms of the production sequence, logistics and supply‐chain management involved in the construction of this enormous funerary assemblage. Of particular interest is a compositional distinction between figures marked with the names ‘Gong’ (宫) and ‘Xianyang’ (咸阳). These seem to represent the products of two workshops involved in the supply of ceramic objects for this ambitious, large‐scale building project undertaken by the Qin Empire during the third century bce .     

Inconsistent,downplayed, and pathologized: How mining's gendered impacts are considered in BC environmental assessment

To what extent do mining environmental assessments in British Columbia (BC) consider gendered impacts? How are they considered? And how are these considerations shaped during the environmental assessment process? To answer these questions we undertook a systematic review of all completed BC mining environmental assessments between 1995 and 2019 (n = 37). Through a careful reading of documentation archived in the BC Environmental Assessment Office registry, we found that 60% of projects did not consider the gendered impacts of mining development; the remaining 40% of projects inconsistently assessed gendered impacts. While noting an increase in gender considerations in environmental assessments since 1995, also quantified in our results is what has not changed. Even where gender is considered, the assessments often collapse this concern into one of “women's issues,” obscuring intersectional impacts and downplaying violence along racialized and gender diverse lines, including those experienced by Indigenous women, children, two-spirit, trans, queer and non-binary people. Environmental assessment is a regulatory tool designed to adjudicate the impacts of mining projects, yet our results lead us to conclude that it is also a tool of environmental injustice, compounding and further sedimenting heteropatriarchal and racialized patterns produced through generations of settler colonial resource extraction in BC.     

Sapwood estimates in the interpretation of tree-ring dates

Many timber finds lack some or all of the outer, sapwood rings formed in the years just before felling. In order to estimate felling date once the outermost remaining ring has been dated, it is necessary to estimate the number of sapwood rings originally present. Methods doing this for oak are reviewed in the light of an intensive study of living trees at one site and an extensive study of 175 samples from living trees in North Wales and northwest England. Some methods reported in the literature are found to be invalid. A method reported by Hollstein (1965) is most reliable, with modifications for known variations in sapwood number with position in the tree. At present the best available estimate is that a value of 30 sapwood rings be used (95% confidence limits: 19–50).
