The complexity of hunter-gatherer technology has been measured by counting artifact parts or production steps. There are a variety of alternative approaches to the measurement of artifact or system complexity. If technological complexity is assumed to reflect the complexity of the problem (or amount of entropy reduction) that the artifact is designed to address, the most appropriate measure of technological complexity is functional design complexity, which entails application of the entropy formula from information theory to the making and using of an artifact and the results obtained by its use. Functional complexity is related to structural or hierarchical complexity, because the entropy formula can be represented as a hierarchy (or step-by-step reduction of entropy) and the functional differentiation is related to the structural differentiation of an artifact. Another approach to hunter-gatherer technological complexity entails definition of a class of “complex artifacts” on the basis of general design characteristics (e.g., incorporation of moving parts). The most structurally and functionally complex artifacts are those that possess multiple states, either through changes in the physical relationship between parts (or sub-parts) during use or through structural differentiation. Although functional complexity is difficult to measure, structural or hierarchical complexity may be measured—and multiple-state artifacts may be counted—with adequate ethnographic and archaeological data on hunter-gatherer technology. 相似文献

Thelodont scales and associated fragments of conodont elements identified as Turinia sp. cf. Turinia australiensis and Ozarkodina sp. cf. Ozarkodina buchanensis respectively are described for the first time from the Early Devonian Murray Creek Formation of Reefton, New Zealand. The conodont and thelodont components of the fauna suggest a late Pragian to early Emsian age for the assemblage. 相似文献

While the issue of refugees and asylum-seekers has preoccupied many European countries, until the November 2001 federal election Australia had largely been immune from the problem. In the election, border protection—combining the Tampa crisis with the ‘war against terrorism’—were central electoral issues. Analysis of the 2001 Australian Election Study shows that border protection cost Labor the election. Labor suffered defections to the Democrats and Greens over its position on refugees and asylum-seekers, and defections to the Coalition on terrorism. Negative public attitudes towards asylum-seekers rested on oppo sition to immigration, but also on a particular dislike of arrivals from the Middle East. By contrast, support for the ‘war on terrorism’ was based mainly on notions of fairness and democracy. Of the two border protection issues— asylum-seekers and terrorism—terrorism was the more important of the two in shaping the election outcome. If 11 September had occurred but the Tampa crisis had not, the Coalition would in all probability still have won the election. 相似文献

Among the 1983 changes to the electoral rules for Australian Senate elections using the Single Transferable Vote (STV) was a new procedure for determining the transfer of vote surpluses. The adoption of this modified (‘inclusive’) Gregory method has tended to be overlooked in the literature, yet as this article shows—using both hypothetical and real-world examples—it incorporates an anomaly that could have significance for electoral outcomes. This has important implications not only with regard to whether the ‘correct’ candidate is elected, but also for wider social choice debates over the quasi-chaotic nature of STV. 相似文献

This paper presents a thermal model for the prehistoric origin and development of clothing. A distinction is drawn between
simple and complex forms of clothing, with broad implications for the interpretation of paleolithic technological transitions
and the emergence of modern human behavior. Physiological principles and paleoenvironmental data are harnessed to identify
conditions requiring simple, loosely draped garments and the more challenging conditions that demanded additional protection
in the form of complex garment assemblages. No actual clothing survives from the Pleistocene, yet the archaeological record
yields evidence for technological and other correlates of clothing—more evidence than is generally supposed. Major innovations
and trends in the distributions and relative frequencies of lithic and other tool forms may reflect the changing need for
portable insulation in the context of fluctuating ice age climates. Moreover, the nonthermal repercussions of complex clothing
can be connected with archaeological signatures of modern human behavior, notably adornment. Alternative models are less parsimonious
in accounting for the geographical and temporal variability of prominent technological and other behavioral patterns in association
with environmental change. 相似文献

The military justice records of the Armies of Italy and theSambre and Meuse reveal that, despite their contrasting militaryfortunes during the campaigns of 1796–97, their experienceswere very similar in many respects. The records of the conseilsmilitaires of the year IV (1795–96) and the conseils deguerre of the following year reveal both conditions of servicein the two armies and the circumstances and attitudes that regulatedthe relationship between soldiers and civilians in Italy andGermany. The conseils de guerre, instituted to remedy the perceivedlaxity of the conseils militaires, operated on similar principlesto their much-maligned predecessors. Occasional instances ofexemplary severity apart, these conseils frequently mitigatedboth charges and sentences, reserving the full severity of thelaw for soldiers who were not present to receive punishment.The councils protected miscreant soldiers more effectively thanthey did vulnerable civilians, but they nonetheless affirmed,if only in principle, the idea that revolutionary warfare shouldbe contained within legal limits. 相似文献

A Sensitive High Resolution Ion MicroProbe (SHRIMP II) has been used to make high spatial resolution in situ micro-analyses of oxygen isotopes in fish otoliths, and teeth from fossil herbivores and a Neanderthal. Large intra-tooth variations in the oxygen isotopic composition (up to 9‰) were observed in the enamel of herbivores from the Neanderthal fossil site of Payre, consistent with preservation of seasonal cyclicity. The range of isotopic compositions observed in Neanderthal tooth enamel was much smaller (∼3‰), possibly the result of a longer enamel maturation time averaging out variability. An archaeological otolith from a Preceramic site in Northern Peru exhibited marked changes in δ18O over life, due either to the fish occasionally migrating from the sea to a lower salinity habitat, or to short-lived rises in sea water temperature. A fish otolith from Australia's Willandra Lakes World Heritage Area showed clear seasonal variations, but also a general trend towards isotopically heavier and more saline water, as indicated by higher δ18O and Sr/Ca values resulting from increased evaporation. The results of these case studies are compared to results of oxygen isotope analysis using more conventional methods and demonstrate the ability of the SHRIMP II to provide precise high spatial resolution in-situ oxygen isotope analyses of a variety of biogenic materials. This approach has major advantages over conventional methods. It can provide rapid, micro-scale isotopic analyses of sub-permil precision without the need for chemical preparation of the sample. 相似文献

The suitability of imagery from the Advanced Very High Resolution Radiometer (AVHRR) on the NOAA series of satellites for the synoptic classification of circulation trends in the European Arctic is assessed with reference to data from three climate stations. Simplified synoptic cyclonic classifications are derived from the satellite imagery and tested against climate data. Five classes of frontal system are derived from the tracking of systems over the UK‐Scandinavia‐Baltic region using 1460 satellite images over two years. An index based on the qualitative interpretation of satellite imagery was related to the reference data. The tracking of the systems in the imagery also facilitates a comparison of travel times across the region and the frequency of occurrence. Frontal systems that remain largely stationary over the Baltic were found to correlate best with precipitation at the reference sites. The paper thus investigates the use of AVHRR imagery for the categorisation of weather patterns towards deriving quantitative relationships between circulation classes and weather elements (such as temperature and precipitation) where, for example, climate data are sparse or where skills required for the interpretation of Height Potential Fields are lacking. 相似文献
