Surface dating by luminescence: An overview

Daylight radiation resets luminescence ‘clock’ to zero on rock surfaces, but transmission depends on the transparency of the rock. On burial, surfaces are no longer exposed to daylight and accumulation of trapped electrons takes place till the excavation. This reduction of luminescence as a function of depth fulfils the prerequisite criterion of daylight bleaching. Thus rock artefacts and monuments follow similar bleaching rationale as those for sediments. In limestone and marble, daylight can reach depths of 0.5–1 mm and up to 16 mm respectively, while for other igneous rocks e.g. quartz in granites, partial bleaching occurs up to 5mm depth under several hours of daylight exposures and almost complete beaching is achieved in the first 1 mm within about 1 min daylight exposure. The ‘quartz technique’ for limestone monuments containing traces of quartz enables their dating with Optically Stimulated Luminescence (OSL) techniques. The surface luminescence (thermoluminescence, TL or OSL) dating has been developed and further refined on various aspects of equivalent dose determination, complex radiation geometry, incomplete bleaching etc. A historical review of the development including important applications, along with some methodological aspects are discussed.     

Enlightenment and reform: an overview of culture and politics in Enlightenment Italy

This essay analyses the influence of the work of Franco Venturi on Italian studies of the eighteenth century over the last fifty years. Venturi's ‘model’ has certainly been of fundamental importance in stimulating new research on the connections between Enlightenment and reform in the eighteenth-century Italian states and is still an essential point of reference for all research in the field. But the direction of eighteenth-century studies in Italy has been shaped also by the contributions of many other scholars. Starting in the 1970s Italian historians became increasingly interested in new questions that were being posed by historians in France and Britain, which contributed to a more general shift away from the biographical focus on individuals characteristic of much of Venturi's work in favour of more collective topics, new types of sources and new ways of interpreting them. This article describes the different themes around which relations between culture and politics in eighteenth-century Italy have been studied, from civil, military and ecclesiastical institutions to the administrative and reform elites, the world of salons and sociability, publishing, religious beliefs, gender differences and science.     

Parliamentary History: An Oblique Glance*

Because parliamentary history has entered the DNA of English and anglophone historiography, one readily forgets how unusual are its parameters and influence in wider historical writing in the West. This essay supplies a reminder that we can look sideways at that historiographical form and think about the place of parliamentary history in societies so different as those of the United States and Europe. Doing so reveals oddities in the place of parliamentary history in divergent cultures and brings into question the viability of the subject in the light of current persuasions that have become hegemonic – the cultural, the gendered, the global. The enquiry concludes that the future of parliamentary history will rest on its ability to come to terms with some of those persuasions and relocate itself within their imperatives.     

The late Upper Paleolithic in Italy: An overview

Previous studies of the Italian late Upper Paleolithic, or Epigravettian, have been primarily chronostratigraphic and typological. Only recently has attention been paid to environmental and behavioral data. The Epigravettian covers some 10,000 years, from about 20,000 B.P. (beginning of the last Wurm stadial) to about 10,000 B.P. (end of Dryas III and beginning of the Holocene). Traditionally, it has been divided into three phases: Early (20,000–16,000 B.P.), Evolved (16,000–14,000 B.P.), and Final (14,000–10,000 B.P.). The Evolved and Final Epigravettian have five regional facies: northern Tyrrhenian, central and southern Tyrrhenian, northern and central Adriatic, southern Adriatic and Sicilian. After an extensive summary of the available environmental data and traditional artifact analyses, we illustrate the present status of more behaviorally oriented research and discusss the consistency of the subdivisions in space and time. Suggestions are made of possible directions for future research.     

Geological importance of luminescence dates in Oman and the Emirates: An overview

In the Wahiba Sands of eastern Oman, luminescence dating of sands enables us to relate wind activity to climatic variations and the monsoon cycle. These changes resulted from Polar glacial/interglacial cyclicity and changes in global sea levels and wind strengths. Luminescence dates show that development of the Sands began over 230 ka ago when the sand-driving winds were the locally arid, northward-blowing SW Monsoon.     

Middle Holocene hunter-gatherers of Cis-Baikal, Siberia: An overview for the new century

The paper examines Middle Holocene hunter-gatherer adaptive strategies in the Baikal region of Siberia based on diverse data (radiocarbon, mortuary, geochemical, genetic, human osteological, and zooarchaeological) accumulated over the last 10–15 years. The new model emphasizes the cyclical nature of the long-term changes and recognizes similarities between the Early Neolithic and Late Neolithic–Early Bronze Age cultures. The overall impression seems to be that change in the region was rapid rather than gradual. A number of interesting correlations between various cultural and environmental variables have been identified. During the Early Neolithic and Late Neolithic–Bronze Age, the spatial distributions of mortuary sites, open landscape, and good fisheries are all correlated and both intervals are coeval with periods of environmental stability. For the Early Neolithic two additional sets of correlated variables have been identified: (1) the uneven distribution of fish resources, uneven distribution of the human population, and cultural heterogeneity; and (2) poorer overall community health, more extensive male travel and heavier workloads, and higher reliance on fishing. For the Late Neolithic–Early Bronze Age, the sets of correlated variables are somewhat different: (1) more even distribution of terrestrial game resources (herbivores), more even distribution of the human population, and cultural homogeneity; and (2) better overall community health, less travel and lighter workloads, more equitable distribution of labor between males and females, and higher reliance on game hunting. Viewed together, these patterns emphasize the much more dynamic pattern of hunter-gatherer cultural variability, temporally and spatially, compared to what was known before.
