“Living together separately”: Thoughts on the relationship between political science and political geography

In their provocatively titled book, Living Together Separately, Michael Romann and Alex Weingrod argue that the shared terrain of Jerusalem obscures deep divisions in the physical and social lives of its Arab and Jewish ethnic communities (Romann & Weingrod, 1991). Multiple divisions exist not only among peoples sharing a common space; they are also found among communities of scholars sharing common intellectual interests. This has certainly been the case of Political Science and Political Geography during much of the twentieth century. Members of both disciplinary communities seek insights into the role of politics and political structures in human society, yet until recently they have pursued their work within orbits that only rarely intersected. They attended different conferences and symposia, they employed different methodological tools, and they did not draw heavily on each others published work.Recent theoretical and empirical developments have begun to erode the barriers separating Political Science and Political Geography, and a discussion of the relationship between the disciplines is thus both timely and welcome. Professor Elazar is an appropriate person to place at the center of this discussion, for his work as a political scientist is unusual sensitivity to geography. Professor Elazar's comments about research orientations and career constraints provide an interesting point of departure for such a discussion, but to understand the nature and depth of the divide between the disciplines it is important to consider the core intellectual constructs and practices that have characterized Political Science and Political Geography during the twentieth century. These have fostered theoretical orientations and research approaches that are sufficiently different from one another to create significant barriers to interdisciplinary contact.     

Field data validation of an algorithm for computing obsidian effective hydration temperature

This paper describes an analysis to validate the effective hydration temperature (EHT) algorithm for obsidian [Rogers, A.K., 2007. Effective hydration temperature of obsidian: a diffusion-theory analysis of time-dependent hydration rates. J. Arch. Sci. 34, 656-665], using hourly temperature data from the Amargosa Desert Research Site near Beatty, NV. These data were used as input to a numerical model of the temperature-dependent diffusion process, and EHT was calculated yearly and for the aggregate. The same temperature data were processed to extract input parameters for the climatic model reported and used as input for EHT computation. EHT as computed from recorded hourly data was found to be within 1 °C of that computed from the climatic model. It is also shown that computed EHT differences between sites are not sensitive to whether air or surface temperature data are used, as long as they are used consistently; however, surface temperature data must be used if depth corrections are to be made.     

A new Late Famennian lungfish from New South Wales,Australia, and its bearing on Australian-Asian terrane relations

A new genus and species of lungfish with toothplates, Adelargo schultzei, is described from the Hunter Siltstone (Devonian, Late Famennian) near Grenfell, New South Wales. Materials assigned to Adelargo schultzei gen. et sp. nov., include a portion of the left side of the skull comprising B, I (postparietal) and J (parietal) bones, pterygoid and prearticular toothplates, a parasphenoid with a long posterior stalk, vertebrae, ribs, anal fin supports and scales. Toothplates are similar to Dipterus, although morphology of the skull, parasphenoid and postcranial elements is more derived. Biogeographic relationships of the Grenfell fauna were based on the presence of the antiarch group Sinolepidoidei, also present on Asian terranes during the Late Devonian. A small number of lungfish scales have been described from Asian sinolepid localities of this age, but differ from those of Adelargo schultzei, and other faunal similarities between these areas appear limited. Paucity of eastern Australian Devonian taxa on the North and South China blocks implies that strong biogeographic relationships between eastern Australia and Euramerican localities during the Late Devonian were not the result of Asian migration routes, but the closer proximity of these areas.     

Burning wood or burning bone? A reconsideration of flotation evidence from Upper Palaeolithic (Gravettian) sites in the Moravian Corridor

This paper compares archaeobotanical and other data from new excavations at two Upper Palaeolithic sites — Dolní V?stonice II and P?edmostí I — in the Moravian Corridor, Czech Republic. Both contain the traces of broadly contemporary ‘Gravettian’ occupations during the warmer episodes of the Pleistocene which preceded the last glacial maximum. Yet their archaeobotanical remains show striking differences — those from Dolní V?stonice II being dominated by large quantities of conifer wood charcoal, while those from P?edmostí I are much more scanty and dominated by vitrified plant remains, in association with large quantities of burnt bone. We argue that these differences between these two datasets arise from different uses of fuel at either site: bone at P?edmostí I and wood at Dolní V?stonice II. Subsequently, we explore the possible reasons for this difference and argue that once likely taphonomic distinctions are accounted for, these data on fuel use offer fresh insights into the functions and durations of these Upper Palaeolithic occupations of the Moravian corridor and some possible implications for how archaeobotanical data from such sites should be interpreted.
