Dual‐Use Technology In the Context of the Non‐Proliferation Regime

Many technologies have both vital legitimate uses and potent military applications. An international regulatory regime has been devised for the purpose of monitoring the use of the most dangerous of these technologies, namely chemical, biological and nuclear weapons. Multiple examples of the use of chemical and biological weapons against members of the public, and evidence of prohibited state weapons development programs, demonstrate the vital need for a more effective enforcement regime. The authors discuss the concept and threat of dual‐use technology, the existing regulatory regime and its shortcomings, and propose enhancing this regime with powerful international judicial authorities to enable the prosecution of any state, group or individual who attempts to misuse dual‐use technology.     

Identifying pottery clay from rice fields: an example from southern Luzon,the Philippines

The general type of clay used by potters can often be identified from attributes of the finished ceramic vessel or sherd. This information is important for compositional and sourcing studies and may also shed light on the variables influencing clay choice such as social, economic, and landscape use patterns. Rice paddies are one type of clay source that are readily identifiable in archaeological ceramics. This paper describes rice paddy clays gathered during ethnoarchaeological studies of traditional potters in Paradijon, southern Luzon, the Philippines. We analyze the effects of clay processing and vessel manufacture on these clays and find that the most diagnostic attribute of paddy soils, the iron oxide mottling, is retained in finished vessels.     

Technological features of Apulian red figured pottery

Apulian red figured pottery samples, dating back to the 5th and 4th centuries BC, from the archaeological site of Monte Sannace (Gioia del Colle, Bari, Italy) have been characterized from the physical–chemical, mineralogical and morphological points of view. Scanning electron microscopy, X-ray diffraction and atomic spectroscopy investigations have been carried out on the ceramic body, red decorated area and black gloss of the fragments, with the aim of outlining the technological features and of defining the nature of coatings and decorations. All 5th century fragments show the same features: fine texture of the ceramic body, red figures saved from the ceramic paste and black gloss painted directly on the ceramic body. The statistical treatment of compositional data of ceramic bodies excludes the local production of these objects. As regards the 4th century fragments, some show similar features to the 5th century ones; however others are characterized by the coarse texture of their ceramic body and an intermediate red layer of finer clay between the black gloss and the ceramic body. The analytical results make it possible to distinguish two different production technologies of red figured Apulian vases in Monte Sannace during the 4th century BC. Certain vases were produced using the “classic” Attic technology and others with a different technique, not previously known, which involved the application of a red engobe layer on the clay paste, before the black gloss painting.     

ON THE ADVANTAGE AND DISADVANTAGE OF BLACK HISTORY MONTH FOR LIFE: THE CREATION OF THE POST‐RACIAL ERA

This article takes the Nietzschean dictum that history must “serve life” as a point of departure for an analysis of the American institution of Black History Month. Many continue to place great faith in the power of historical education to solve problems of race in America. Against this common‐sense view, this article argues that the excessive historicization of the problem of racism is at least as oppressive as forgetting. The black history propagated during this month has mostly been a celebration that it is history and thus a thing of the past. The article makes the claim that it is precisely a surfeit of black history that has encouraged the view that racism is vanishing in the river of time. The constant demand to view American racism through a historical frame has led to the perception that racism is a problem that must be historically transcended rather than solved. In other words, it is through the widespread dissemination of black history during Black History Month and elsewhere that the historical category of the post‐racial era has been constituted. The postracial era is not, as is so often claimed, a denial of historical context. On the contrary, it is an assertion that the horrors of racist discrimination were once real but are now over and done with.     

Earthenware production and distribution in the prehispanic Philippine polity of Tanjay: results from laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS)

This paper presents the results of laser ablation-inductively coupled plasma-mass spectrometry (LA-ICP-MS) analysis of low-fired earthenware from the prehispanic trading polity of Tanjay (c. A.D. 500–1600) in the central Philippines. The goal of this project was to determine whether or not the compositional analysis of ceramics could be used to examine the organization of pottery production and exchange relationships in the Bais-Tanjay region of Negros Island. Results indicate that at least five distinct groups of ceramics can be differentiated based on elemental compositions and that pottery production was both a part-time, dispersed endeavor and a full-time, likely centralized, craft. In addition, a number of compositional outliers in the ceramic dataset suggest that interregional trade took place, with pottery made outside the Bais-Tanjay region being imported, especially by upland swidden farmers.     

Manganese Black Pigments in Prehistoric Paintings: the Case of the Black Frieze of Pech Merle (France)

Different black pigments of natural origin (mineral or organic) have been examined by means of several analytical methods (colour measurements, elemental analysis and structural analysis). The results, after being compared with each other, then served as reference points in the study of the ‘Black Frieze’ of the cave of Pech Merle (Lot). After that, colour measurement was investigated in situ on the paintings as a means of displaying small differences (in hue or chroma) between the black colours. The aim of this study was to verify several hypotheses concerning the techniques used by the painters of Pech Merle, and specifically by the one(s) of the Black Frieze. A first objective was that of identifying the nature and, if possible, the origin of the black pigments used in these figures. A second objective was that of determining in which parts of the frieze one or the other (or one and the other) had been used; and the final objective was to provide new technical information that might help us better to understand how the Pech Merle frieze was produced, whether by a single painter and in one episode, for the most part, or, on the contrary, in several episodes and by a succession of different painters.     

Ceramic production,consumption and exchange in the Banda area,Ghana: Insights from compositional analyses

Ceramic production, exchange and consumption in the Banda area, west central Ghana has been affected by historical developments ranging from recent competition with alternative vessels (made of metal and plastic) to political economic upheavals that altered community relationships within and outside the region. In this study, we explore spatial and temporal patterning in pottery production, exchange and consumption using a combination of analytical techniques. Instrumental neutron activation analysis (INAA) of a large sample (491 specimens) of archaeological and ethnographic pottery, clay and temper samples from sites across the Banda area has led to the identification of seven compositional groups whose differential distribution implies shifts in resource selection through the last thousand years. Laser ablation-ICP-MS analysis was used to explore the effects of distinctive tempering agents (crushed slag) on the bulk chemical signature of a subset of Banda ceramics, while petrographic analysis provides insight into the preparation of ceramic fabrics. We integrate insights from these diverse physical studies to investigate the dynamics of pottery production, exchange and consumption over the course of the last millennium in the Banda area and explore potential linkages with broader political economic transformations.     

The colourless glass of Iulia Felix

The present paper focuses on 85 colourless glass samples selected among the recycling cullet found in the Roman ship Iulia Felix, wrecked off the town of Grado (province of Udine, North Italy) in the first half of the 3rd century AD, with the aim of examining their chemical composition, investigating similarities within and between the three established group types (cups, plates, bottles), and comparing the chemical compositions of the Iulia Felix glass samples with groups reported in the literature for colourless glasses. Chemical analyses, performed by X-ray fluorescence and electron microprobe, indicate that the samples were all soda-lime–silica in composition, with natron as flux, according to typical Roman production technologies. Chemical data are treated by multivariate statistical tools, such as cluster analysis and the NPC test. Statistical analyses allow us to conclude that the Iulia Felix colourless glasses were produced by at least two different production technologies related to group type, confirming the trend recently identified in the literature. In addition, the trace element patterns (particularly those of Sr, Zr and Ba) suggest that beach sand with differing amounts of alkali feldspars was predominantly used as raw material, like those specifically mentioned by Pliny for glass production.     

Globalisation and the decline of national identity? An exploration across sixty‐three countries

The relationship between globalisation and national identity is puzzling. While some observers have found that globalisation reduces people's identification with their nation, others have reached the opposite conclusion. This article explores this conundrum by examining the relationship between globalisation and people's feelings towards national identity. Using data from the International Social Survey Program National Identity II ( 2003 ) and the World Values Survey ( 2005 ), it analyses these relations across sixty‐three countries. Employing a multilevel approach, it investigates how a country's level of globalisation is related to its public perceptions towards different dimensions of national identity. The results suggest that a country's level of globalisation is not related to national identification or nationalism but it is related negatively to patriotism, the willingness to fight for the country and ethnic conceptions of membership in the nation. An examination of alternative explanations indicates that globalisation has a distinct impact on national identity.
