The Price of Peace: A Predictive Model of UN Peacekeeping Fiscal Costs

This study devised a predictive model of peacekeeping fiscal costs based on an analysis of all United Nations peacekeeping operations since 1945. Our results indicate that the costs of a peacekeeping operation were significantly influenced by the length of that mission and the size of the force deployed. Beyond these factors, the historical development from observer to second generation missions has produced more costly operation.     

The geochronological potential of isoleucine epimerisation in cassowary and megapode eggshells from archaeological sites

Our research demonstrates that the extent of isoleucine epimerisation (A/I) in fragments of avian eggshells provides geochronological information in archaeological contexts. In the archaeological sequence of Hay Cave, northern Queensland, Australia, there is an excellent correspondence between the A/I values of Australian brush-turkey (Alectura lathami) eggshells (n = 99) and independent geochronological control (n = 16 radiocarbon ages including 4 on eggshell calcite). The A/I values identify three phases of deposition during the Holocene at Hay Cave. In contrast to the Alectura eggshell A/I values, a poor correspondence was observed between the A/I values of cassowary (Casuarius) eggshells from Toé (n = 35) and Kria caves (n = 23) (Ayamaru Plateau, Papua) and the depths from which the specimens were recovered in these stratified sequences. Given coherent archaeofauna trends and radiocarbon chronologies (n = 8 and 2 eggshell calcite radiocarbon ages at Toé and Kria, respectively) with respect to depth, the variable A/I values are not explicable in terms of mixing. Rather, the variability is most likely due to exposure of the eggshells to the high temperatures of campfires. Despite the variability, eggshells with relatively low A/I values amongst specimens recovered from similar depths (and therefore presumably least influenced by high temperatures) exhibit a gradual increase in A/I with respect to depth, as expected in a stratified deposit. From this observation it is suggested that the identification of heated eggshells will increase confidence in geochronological information provided by A/I. These studies illustrate the complications that arise from campfire-induced acceleration of amino acid racemisation and emphasise that although this phenomenon is common, it is not universally encountered in archaeological contexts.     

Locally diagnostic phytoliths of wild rice (Zizania palustris L.) from Minnesota,USA: comparison to other wetland grasses and usefulness for archaeobotany and paleoecological reconstructions

Wild rice (Zizania spp.) is an important native grain of north-central North America, with spiritual and subsistence significance to many native peoples. Due to lack of suitable proxies, its past distribution and pattern of use are poorly known. This study demonstrates the diagnostic value of silica phytoliths from Z. palustris as a proxy tool to detect its past occurrence in a variety of paleoenvironmental and archaeological contexts. Our main findings are: 1) Dominant wetland grass species in Minnesota produce phytoliths distinct from Zizania phytoliths; 2) Closely related Leersia oryzoides produces a few Zizania-like phytolith morphotypes; however, these potential confusers can be identified based on 2-D and 3-D morphologies; 3) Z. palustris produces a wide variety of phytolith morphotypes, many of which are only found in certain parts of the plant (e.g., Inflorescence Type 1 from the spikelet); 4) Z. palustris produces 23 locally diagnostic phytolith morphotypes that can be used to determine the presence and abundance of wild rice in modern and paleo lake sediments; and 5) Wild rice phytolith Inflorescence Type 1 is the morphotype most likely to be observed in archaeological contexts, and may be unequivocally diagnostic for the genera Zizania.     

Towards a critical political ecology of human–forest interactions: collecting herbs and mushrooms in a Bulgarian locality

This paper presents a critical political ecology of human–forest interactions in a Bulgarian locality. Based on primary fieldwork carried out annually since 1992, the argument is advanced that even in a relatively small space, environment–society relationships are sufficiently complex to make the enterprises of empirical analysis and theory-building quite challenging. Yet, as this case study of informal resource use practices shows, it is precisely because environment–society relationships are so intertwined that a 'symmetrical' treatment of humans and non-human actors is required; one that takes us well beyond the traditional political ecology of Blaikie or Black, but which, I shall argue, does not escape it entirely. Through a detailed ethnographic account of herb and mushroom collecting I develop the idea of 'symmetry' in three distinct ways. First I will explore the by now well-publicised notion that non-humans can be actors too. Second this basic insight will be developed via the more advanced conceptualisation of entities such as Thrift's 'effloresences' or expressions of 'distributed' information spaces and applied to the case study of herb and mushroom collection in a southwestern Bulgarian locality. Finally I consider the theoretical and practical policy implications of this analysis for all concerned, but most particularly those who claim to 'manage' and 'regulate' human–forest interactions.     

Businesses, Green Groups and The Media: The Role of Non-Governmental Organizations in the Climate Change Debate

The lion's share of media and governmental commentary on the recent Sixth Conference of the Parties (COP-6) to the UN Framework Convention on Climate Change has focused on rifts between the EU and the 'Umbrella Group' of countries, including the United States, Canada and Japan, and has led many observers to speculate that intergovernmental negotiations on climate change may have irretrievably broken down. Limiting the focus solely to political difficulties with specific issues, however, emphasizes only part of the story and takes no account of the complex context in which the international negotiations are embedded. This approach does not give sufficient credit to the growing momentum gathering outside the negotiating halls. This article examines recent and rapid changes in attitude and awareness among non-governmental groups-including business and industry, environmental groups and the media-on the issue of global climate change, and the impact these changes have had on the negotiating process and the overall climate change debate. Together these groups provide encouraging signs of a shift in public opinion and ample proof that the failure of the talks in The Hague does not signal the end of the road.     

Sensitivity of bulk sedimentary stable carbon isotopes to prehistoric forest clearance and maize agriculture

The stable carbon isotope compositions (δ¹³C) of tropical lake sediments and soils have been used to reconstruct the occurrence of prehistoric maize cultivation and its relative importance through time. This study assesses some of the possible variables affecting the response of lake sediment bulk organic carbon isotope (δ¹³C_TOC) values to variations in the scale of prehistoric maize cultivation and the potential of this proxy to yield quantitative estimates of the scale of prehistoric maize agriculture in small tropical watersheds. High resolution analyses of δ¹³C_TOC values, maize pollen concentrations, and mineral influx were conducted on sediments deposited during a ∼220 year period of prehistoric maize agriculture in the watershed of Laguna Castilla, a small lake in the mid-elevations of the Cordillera Central, Dominican Republic. Close correspondence between δ¹³C_TOC values and maize pollen concentrations in the Laguna Castilla sediment record indicates a close relationship between the isotopic values and the scale of prehistoric maize cultivation. Correlations between the δ¹³C_TOC signature and mineral influx indicate that the isotope record is also sensitive to variations in allochthonous carbon delivery. This study establishes that sedimentary δ¹³C_TOC values can provide a highly sensitive proxy of the spatial scale of prehistoric maize agriculture in small tropical watersheds, but emphasizes the need for a better understanding of sediment dynamics and carbon cycling in anthropogenically modified landscapes before this proxy can be widely employed in diverse archaeological settings.
