An Early Upper Palaeolithic Stone Tool Assemblage from Mughr El-Hamamah,Jordan: An Interim Report

Mughr el-Hamamah (Jordan) Layer B contains an Early Upper Palaeolithic stone tool assemblage dating to around 39–45 kya cal b.p. This assemblage is unusual in that it samples human forager activities around the ecotone between the Transjordanian Plateau and the palaeo-lake (Lake Lisan) that filled much of the Jordan Valley during Late Pleistocene times. This paper describes that assemblage, comparing it to other Levantine Upper Palaeolithic assemblages of equivalent antiquity. The Mughr el-Hamamah Layer B assemblage appears most similar to Early Ahmarian assemblages, but it departs from typical such assemblages in ways that may reflect local conditions’ influence on human activities carried out in and near the cave. Mughr el-Hamamah raises new questions about changes in residential mobility, off-site provisioning and foraging activity, and on-site task diversity in the Early Upper Palaeolithic period.     

Testing the efficacy and reliability of common zooarchaeological sampling strategies: a case study from the Caribbean

Zooarchaeological analysis typically involves implementing a suitable sampling strategy that provides meaningful information representative of a site under investigation. To test the efficacy of how various sampling procedures can influence interpretation of a faunal assemblage, we analyzed in full, a large assemblage of mollusks (minimum number of individuals [MNI] = 58,000+) from the late Ceramic Age (ca. AD 850–1440) site of Coconut Walk on the island of Nevis (northern Lesser Antilles, Caribbean). These remains were recovered from 25 discrete 1 × 1 m units within a larger 5 × 5 m trench that overlaid a dense midden deposit. Using statistical procedures, we compared the results of the number of identified specimens (NISP), MNI, and weight (g) of each mollusk taxon between both units and plana to determine how different sampling strategies would have affected the interpretation of mollusk composition across space and time had different sampling procedures been used. The results reveal that sampling less than 16% (4 out of 25 squares for this study) of a midden is likely to produce results outside of a 95% confidence interval for the population composition, with samples of connected squares having a higher likelihood to lie outside the interval. Discerning change between plana (or layers) may require a larger sample (i.e., 16%+). In addition, samples selected randomly or judgmentally will produce similar results, provided that proper spacing is given between units. The data in this case suggest that the midden was efficiently sampled for midden composition and key species at a rate of 16% of the surface area.     

Diatom and dinoflagellate assemblages of the Hawkesbury River,N.S.W., over the last two centuries: evidence for changes in hydrology

Diatom and dinoflagellate cyst analysis of a 77 cm long sediment core from Cowan Creek, Hawkesbury River estuary, N.S.W., revealed changes in the catchment hydrology over the last 266 years. High abundances of the freshwater/brackish diatom genus Cyclotella at the base of the core imply sustained periods of reduced salinity that now no longer occur. Reduction of freshwater flow after approximately circa 1800 (60 cm) has allowed the development of marine planktonic diatoms Thalassiosira spp.,Ditylum brightwellii, Rhizosolenia setigera, Pseudo-nitzschia pungens and Chaetoceros spp. Benthic diatom diversity has remained relatively unchanged. The toxic dinoflagellate Gymnodinium catenatum, although identified in a cyst survey in April 1995, was not found in the sediment cores. Changes in dinoflagellate assemblage are consistent with the effects of increasing urbanisation and eutrophication.     

‘The Constructive Use of Abundance’: the UN World Food Programme and the Evolution of the International Food-Aid System during the Post-War Decades

This article studies the expansion of multilateral economic development aid in the early 1960s by exploring the history of the United Nations (UN) World Food Program. It analyses the pivotal role played by key development economists within the UN Secretariat, such as Hans Singer, alongside US policy-makers in the Kennedy administration in framing and directing the debate on multilateral food aid. It specifically argues that this period marked a shift in how food aid was perceived and utilised by donor and recipient countries - as well as international organisations like the UN and Food and Agriculture Organization (FAO). Ultimately, what began in the 1950s as a bilateral method to feed the hungry through the disposal of surplus agricultural commodities evolved into an international food-aid system by the 1960s centred on the utilisation of surplus agriculture for economic development. This change showcased both the common goals and competing interests of US and UN policy-makers as food aid now joined the wider debate on various doctrines of development.
