New experimental data on the distance of sling projectiles

The range of stones cast by slings used in the past is debated. In the Central Andes, slings are asserted to be important weapons of prehispanic war, and have been recovered archaeologically. Rolled river cobbles and stones presumed to be slingstones found at fortified hilltop archaeological sites are presented as evidence that slings were used at these fortifications. Yet sling use has not been adequately tested at hillforts. Experiments conducted in Europe by a novice slinger have attempted to illuminate the range of sling cast stones at ancient hillforts. Data acquired from native slingers is necessary to more accurately assess distances achieved by projectiles launched by slings. We present data from sling experiments carried out in Puno, Perú among Quechua-speaking herders who are experienced slingers. The results demonstrate that a prior model of the maximum theoretical distance of sling cast stones underestimates their range. Results also show significant differences in the use of slings by men and women, and by different age groups. These new data permit a better approximation of warfare that has bearing on our interpretation of fortified sites.     

Thermoluminescence as a technique for determining the nature and history of small solar system particles

The thermoluminescence phenomenon has been used for pottery dating and radiation dosimetry for sixty years and for forty years has been applied to the study of meteorites, being successful in quantifying metamorphic histories and providing new insights into terrestrial age and orbits. Here we review some of the fundamental properties of thermoluminescence with particular focus on the study of small extraterrestrial particles. We suggest that natural TL data can be used to identify the burial and release history of cometary particles and that induced TL measurements can provide in-sights into the mineralogy of particles (even when largely amorphous) and the metamorphic history of those particles. We illustrate the use of TL to study small particles by describing recent studies on micrometeorites and 10–100 μm fragments taken from the matrix of a meteorite Semarkona which is type 3.0 ordinary chondrite.     

The House that Poison Built: Customary Marine Property Rights and the Live Food Fish Trade in the Kei Islands,Southeast Maluku

The use of cyanide to stun and capture live food fish for export first appeared in the Philippines during the mid‐1970s. Today, this technology has spread throughout Southeast Asia and the Indo‐Pacific region, causing widespread damage to coral reef ecosystems. This study examines the local political and economic changes that have resulted since this destructive trade arrived in the Kei Archipelago of the Southeast Maluku District in Indonesia. District and provincial fisheries and law enforcement officials turn a blind eye, and evidence suggests complicity by some members of the military. Many local fishermen attempt to resist, motivated more by vestigial concepts of communal village rights and rules governing access to coral reef territories and resources, than by some intrinsic sense of environmental conservation. The article challenges the romantic predisposition of indigenous knowledge systems scholarship that characterizes local knowledge and practices as inherently eco‐friendly and socially just, and argues for closer examination of the dynamics involved when local practices and institutions are integrated into larger circuits of production and trade.     

Envisioning Future Landscapes in the Environmentally Sensitive Areas of Scotland

Environmentally Sensitive Areas (ESAs) designated under EC Structure Regulation 797/85 now cover 1.4 million ha of the Scottish countryside and are likely to make a substantial contribution to the regulation of landscape change. Visual changes to landscapes with (policy on) and without (policy off) the ESA programme in two Scottish ESA areas, Breadalbane and the Machair, are predicted through impact-assessment procedures and computer manipulation of photographic images. The methodological requirements for such predictions are outlined and substantial differences in landscape characteristics under policy on/off scenarios are revealed. Such approaches to landscape change are an essential foundation for the development of environmental cost-benefit analyses and will contribute to public consultation processes.     

Edward III’s siege of Calais: A reappraisal

In September 1346, Edward III brought his victorious army to the gates of Calais to begin a siege that over 12 months developed into the largest military operation conducted by the English on French soil during the fourteenth century. It is also perhaps the least understood campaign of Edward III’s reign, because of the loss of the army pay records. We know from chronicles that the men of Calais conducted a heroic defence of their town, and we know too that the English created and maintained an enormous logistical operation first to besiege and then to capture the port. What is little understood, however, is the scale, scope and chronology of the siege. The role played by English naval forces has received little attention, yet there is a series of pay records relating to their service which can compensate for the loss of the vadia guerre accounts and which can enrich understanding of the campaign. Using this evidence, this article reappraises the whole expedition, highlights the numbers of ships and mariners involved in the siege, and draws attention to periods of intensive military activity. Edward III’s ultimate objective was to capture, hold and use the town as a safe port of disembarkation for future invasions.
