Got Silk?: Buying, Selling, and Advertising British Luxury Imports During the Stamp Act Crisis

Description: Despite the amount of scholarship on the Stamp Act Crisis, no study has used advertisements as a main source. This study attempts to show that a valuable, objective source has been overlooked, through the quantitative analysis of 5,810 advertisements before, during and after the Stamp Act Crisis from five port cities: Boston, Charleston, Philadelphia, New York, and Portsmouth. The findings reveal the colonists' strong connection to imported British luxury goods, and a lack of interest in American-made goods, especially before and after the boycott. Advertisements also demonstrate that the decision of many merchants to place the needs and expectations of their community before their own personal gain offered a rare economic opportunity for others. The colonists' devotion to imports tested the strength of the boycott, especially among Boston merchants, who continued to advertise imported goods a good deal more than any other city. This lack of dedication to the boycott on the part of the Boston merchants shows disunity among the colonies, at a time when many argue was the first instance of colonial nationalism. Capitalism challenged and undermined a commitment to communal sentiments such as nationalism. Moreover, if Americans did share a sense of nationhood during the Stamp Act Crisis, it cannot be gauged by a rejection of "Englishness."

MatProps: Material Properties Database and Associated Access Library

Description: Coefficients for analytic constitutive and equation of state models (EOS), which are used by many hydro codes at LLNL, are currently stored in a legacy material database (Steinberg, UCRL-MA-106349). Parameters for numerous materials are available through this database, and include Steinberg-Guinan and Steinberg-Lund constitutive models for metals, JWL equations of state for high explosives, and Mie-Gruniesen equations of state for metals. These constitutive models are used in most of the simulations done by ASC codes today at Livermore. Analytic EOSs are also still used, but have been superseded in many cases by tabular representations in LEOS (http://leos.llnl.gov). Numerous advanced constitutive models have been developed and implemented into ASC codes over the past 20 years. These newer models have more physics and better representations of material strength properties than their predecessors, and therefore more model coefficients. However, a material database of these coefficients is not readily available. Therefore incorporating these coefficients with those of the legacy models into a portable database that could be shared amongst codes would be most welcome. The goal of this paper is to describe the MatProp effort at LLNL to create such a database and associated access library that could be used by codes throughout the DOE complex and beyond. We have written an initial version of the MatProp database and access library and our DOE/ASC code ALE3D (Nichols et. al., UCRL-MA-152204) is able to import information from the database. The database, a link to which exists on the Sourceforge server at LLNL, contains coefficients for many materials and models (see Appendix), and includes material parameters in the following categories--flow stress, shear modulus, strength, damage, and equation of state. Future versions of the Matprop database and access library will include the ability to read and write material descriptions that can be exchanged between codes. It will ...
