DSpace for e-print archives
No full textDSpaceTM (http://dspace.org/) is the new open source digital repository system from the MIT Libraries and Hewlett-Packard Labs designed to support the digital collections of academic research institutions, as well as the SPARC conception of Institutional Repositories for digital research material. The DSpace system has been described elsewhere in detail so the focus of this article is on its implementation at MIT for archiving e-prints and other artifacts of scholarly communication, and making these available to the public. The MIT Libraries are deeply concerned about the well-documented crisis in scholarly communication and are committed to working
towards innovative solutions. We share this concern with many of the MIT faculty and administration, several of who have been key supporters of the DSpace project and related
initiatives at the university. The MIT Libraries were a founding member of SPARC, and are a signatory of the Budapest Open Access Initiative (BOAI). This article will describe how MIT Libraries have implemented DSpace to support these goals

Dissolution of Carbonate Sediments Under Rising pCO2 and Ocean Acidification: Observations from Devil’s Hole, Bermuda
No full textRising atmospheric pCO2 and ocean acidification originating from human activities could result in increased dissolution of metastable carbonate minerals in shallow-water marine sediments. In the present study, in situ dissolution of carbonate sedimentary particles in Devil’s Hole, Bermuda, was observed during summer when thermally driven density stratification restricted mixing between the bottom water and the surface mixed layer and microbial decomposition of organic matter in the subthermocline layer produced pCO2 levels similar to or higher than those levels anticipated by the end of the 21st century. Trends in both seawater chemistry and the composition of sediments in Devil’s Hole indicate that Mg-calcite minerals are subject to selective dissolution under conditions of elevated pCO2. The derived rates of dissolution based on observed changes in excess alkalinity and estimates of vertical eddy diffusion ranged from 0.2 mmol to 0.8 mmol CaCO3 m?2 h?1. On a yearly basis, this range corresponds to 175–701 g CaCO3 m?2 year?1; the latter rate is close to 50% of the estimate of the current average global coral reef calcification rate of about 1,500 g CaCO3 m?2 year?1. Considering a reduction in marine calcification of 40% by the year 2100, or 90% by 2300, as a result of surface ocean acidification, the combination of high rates of carbonate dissolution and reduced rates of calcification implies that coral reefs and other carbonate sediment environments within the 21st and following centuries could be subject to a net loss in carbonate material as a result of increasing pCO2 arising from burning of fossil fuels

Experimental analysis of the manufacture and use of bone and antler tools among the Mackenzie Inuit
No full textBibliography: p. 235-251.Use wear analysis of bone and antler tools has lagged behind studies of stone tools. In this dissertation I have tried to advance the study of microscopic wear on bone and antler.
This study had three main goals. The first was to demonstrate, using theoretical concepts from tribology, that microscopic patterns on bone and antler can be differentiated. To that end, a series of experiments, involving both the manufacture and use of bone and antler tools, was carried out. The second goal was to apply the results of the experimental programme to an archaeological sample. Bone and antler tools from Mackenzie Inuit sites were selected as an appropriate case study. It was found that many of the different patterns defined experimentally could be identified on archaeological tools, but that tools with many possible uses, or which had been used for multiple tasks, are much more difficult to categorize. Finally, the data concerning manufacture and use of bone and antler tools among the Mackenzie Inuit generated by this analysis were used to reconstruct the design system used in making these tools. It is suggested that all the Mackenzie Inuit subgroups included in this study shared the same design system. Based on models from cognitive anthropology, this is taken to indicate a high degree of interaction between the groups.
These results show great promise for future studies of bone and antler technology
