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).     

A love story: for ‘Buddy System’ research in the academy

This article makes a case for a ‘buddy system’ approach to research and scholarship, or a kind of ‘caring with’ our colleagues, as feminist praxis and as an intentional, politicized response to the neoliberalization of the academy. Through autoethnographic writing on our travels together into farmed animal auction yards, we explain the buddy system as a mode of caring, solidarity, and love that differs from collaborative research, focused as it is on caring for and about our colleagues and their research even (or especially) when we have no direct stakes in the research being conducted. We contribute to three feminist conversations with this approach: feminist care ethics in geography; emotional geographies; and critical perspectives on the neoliberalization of the academy. We advocate the buddy system as an extension of feminist care ethics, enriching how feminists think about ‘doing’ research. We draw on feminist geographies of emotion and our own emotions (grief especially) experienced while witnessing processes of nonhuman animal commodification to politicize the act of researching and to develop a more caring way of inhabiting the academy. This is particularly important, we argue, in the context of deepening neoliberal logics that turn the academy into a place where care and love become radical acts of resistance and transformation.
