Transformative tans? Gendered and raced bodies on beaches

Abstract: In this paper I examine the intentional act of transforming the colour of one's skin – sun‐tanning – by Pākehā at three New Zealand beaches: Papamoa, Mount Maunganui, and Takapuna. Recent debates about the construction of whiteness are outlined before discussing the historical significance of beaches and sun to New Zealand's leisure culture. This paper seeks to de‐naturalize whiteness through the disclosure of gendered leisure practices of tanning. Empirical material reveals that Pākehā, who actively seek brown skin, negotiate a number of racialized and gendered ‘truths’ as their sun‐tan transforms their bodies. I conclude by arguing that geographers need to be more attentive to the ways in which place constructs particular forms of gendered whiteness.     

Quantifying flows along hydrological pathways by applying a new filtering algorithm in conjunction with master recession curve analysis

Quantifying the proportion of the river hydrograph derived from the different hydrological pathways is essential for understanding the behaviour of a catchment. This paper describes a new approach using the output from master recession curve analysis to inform a new algorithm based on the Lyne and Hollick ‘one‐parameter’ signal analysis filtering algorithm. This approach was applied to six catchments (including two subcatchments of these) in Ireland. The conceptual model for each catchment consists of four main flow pathways: overland flow, interflow, shallow groundwater and deep groundwater. The results were compared with those of the master recession curve analysis, a recharge coefficient approach developed in Ireland and the semi‐distributed, lumped and deterministic hydrological model Nedbør‐Afstrømings‐Model. The new algorithm removes the ‘free variable’ aspect that is typically associated with filtering algorithms and provides a means of estimating the contribution of each pathway that is consistent with the results of hydrograph separation in catchments that are dominated by quick response pathways. These types of catchments are underlain by poorly productive aquifers that are not capable of providing large baseflows in the river. Such aquifers underlie over 73% of Ireland, ensuring that this new algorithm is applicable in the majority of catchments in Ireland and potentially in those catchments internationally that are strongly influenced by the quick‐responding hydrological pathways.

Sydney's Ethnic Geography: New approaches to analysing patterns of residential concentration

Most studies of ethnic residential segregation in Australian cities have used single-measure indices of dissimilarity and segregation, which access the degree of unevenness between two maps. Segregation is a multi-dimensional concept, however, and in this paper we introduce an alternative way of measuring residential concentration which incorporates several of the key dimensions. The procedure is illustrated using birthplace and language-used-at-home data for collection districts in metropolitan Sydney in 1996. Results show no evidence of extreme spatial concentration of ethnic groups.
