Microfossil analysis of human dental calculus provides consumption‐specific and archaeologically relevant data for evaluating diet and subsistence in past populations. Calculus was extracted from 114 teeth representing 104 unique individuals from a late 16th to early 18th century skeletal series on Rapa Nui (Easter Island) to address questions of human–environment interactions and possible dietary preference. Scanning electron microscopy was used in lieu of optical microscopy for its superior depth of field and resolution of surface detail. The calculus microfossil recovery produced 16,377 total biogenic silica microfossils: 4733 phytoliths and 11,644 diatoms. The majority of phytoliths correspond with the Arecaceae or palm family (n = 4,456) and the minority corresponds to the Poaceae or grass family (n = 277). Because of the relatively large sample size, we were able to test hypotheses related to age cohort, sex, dental element and geographic region. Results indicate no significant difference in phytolith or diatom recovery based on age cohort or sex. The high frequency and proportion of Arecaceae phytoliths found in calculus extracted from the anterior dentition suggests consumption of soft or cooked foods containing palm phytoliths and the high frequency of diatoms recovered from the southern part of the island argue for different sources of drinking water.

Urbanism in the Indian subcontinent occurred in three distinct time periods in which cultural cohesion over large regions is archaeologically demonstrated through the architecture and artifacts of social, ritual, and economic activity. In the Indus (2500–1900 B.C.) and Early Historic (3rd century B.C. to 4th century A.D.) periods, cities were not necessarily tied to political territories or guided by strong political leaders, but by the Medieval period (after the 9th century A.D.), urban zones were the base for political growth, warfare, and aggrandizement. The comparison of these three eras is undertaken within a framework for defining cities that balances quantitative criteria such as population size and areal extent with two types of qualitative criteria: internal specialization on the basis of materials found within archaeological sites, and external specialization on the basis of data recovered through regional analysis. Cities from the three eras also are evaluated from the perspective of the ordinary inhabitant through the examination of the social, religious, and economic factors that prompted and rewarded urban residence. While the Indus and Early Historic cities were attractive because of the networks of opportunity found there, Medieval cities additionally benefitted from a “push” factor as ordinary inhabitants allied themselves to urban areas in times of political stress and uncertainty.

Energy policy-making has become ever-more challenging over the last three decades, comprising a larger and more complex set of inter-related dimensions. Energy policy-makers have to deal with energy as a discrete market sector, pursuing competitive, efficient, safe, and affordable energy. They also have to address environmental imperatives, ensuring energy is developed with due regard for sustainability, ecosystems, air quality, climate change, and the like. In addition, energy policy must address security objectives, which themselves have broadened over time. Finally, energy must be developed in ways that are socially acceptable. This article examines how these four policy dimensions—Market, Environment, Security and Social acceptability, the acronym MESS—have come to characterize energy policy-making in the twenty-first century. It then explores what kind of MESS the Canadian and American governments are making of energy policy—both domestically and bilaterally—and offers some proposals for key sectors and activities that could benefit from greater collaboration. 相似文献

ABSTRACT Reports of patrols through remote areas of Papua and New Guinea led by officers of the Australian administration must be read with care. We discuss the case of a patrol report from the mid 1960s where the patrol cannot have travelled the route indicated on the accompanying map. By cross-referencing to reports from later patrols, we provide both an improved reading of the report in question and, more generally, an appreciation of motivations that influenced the knowledge patrol officers produced. 相似文献
