Multivariate visualization and analysis of photomapped artifact scatters

Simultaneous analysis of relationships between multiple artifact classes is required for characterization of many types of activity areas. This paper illustrates improved forms of multivariate visualization, spatial analysis and integration of experimental results that are possible with GIS based photomapping. Techniques are demonstrated through analysis of a hearth associated artifact scatter exposed during excavations of a Late Archaic pithouse at Jiskairumoko, Peru. A multivariate density raster is created and additive color visualization is used for simultaneous display of three artifact distributions. Performing unconstrained clustering in a GIS, space is classified by simultaneous relative density relationships between multiple object types.     

The Poison and the Spider's Web: Diderot and Eighteenth-Century French Epicureanism

This article argues that the term ‘Epicurean’ had multiple meanings in the moral and political thought of the eighteenth century. Concentrating on the reception of Epicureanism in France, it shows that some critics focused on Epicurus’ hedonistic moral psychology and labelled Epicurean those thinkers who denied natural sociability; for others, who instead focused on Epicurus’ materialist natural philosophy, to label a thinker an Epicurean was to label them an atheist. This polyvalence is presented as a salutary caution against essentialising claims about the content of eighteenth-century Epicureanism per se. Despite this sceptical stance, however, the article goes on to argue that it is nevertheless fruitful to investigate the engagement with Epicureanism by particular thinkers or in particular texts. Indeed, a comparative reading of Denis Diderot's Encyclopédie entry on ‘Epicuréisme’ and his source material in Johan Jakob Bruker and Pierre Bayle demonstrates that Diderot used his discussion of Epicureanism to intervene directly in contemporary theological controversies over the immortal soul and a providential god.     

I never shall be a white man again: race and junior officers in the Mexican War

Throughout the Mexican War, the impact of professionalization was felt on the battlefields of Mexico. This professionalism did not, and could not insulate these officers from social issues such as race. When American junior officers viewed the filthy conditions in Mexico, they argued that these conditions could only be explained by the racial inferiority of the Mexican people as a race. Volunteers and regulars reacted to these issues in exactly the same manner. This fact challenged the traditional fears that a professional standing army would become disconnected with the society they protected, and would thus become despotic. Similarly, the excesses of the volunteers demonstrated that they were not the paragon of virtue which many in the US hoped.     

An evaluation of Keeley's microwear approach

Lawrence Keeley has developed a microwear approach to lithic use-wear analysis which he claims will enable an investigator to reconstruct aspects of implement function. A notable feature of his approach is the assertion that distinctive wear-polishes form as a result of contact with specific worked materials, making the identification of worked materials possible. To verify the power of this approach, an independent “blind test” was conducted in which Keeley attempted to identify the uses of a set of experimental implements. While the test results support the utility of Keeley's approach in identifying worn areas on an implement and kinematics of use, we suggest the results do not demonstrate the existence of characteristic wear-polishes and thus question the efficacy of this technique in identifying worked materials.A reply by Keeley to this evaluation follows this paper.
