In the fall of 2001, staff of the Florida Bureau of Archaeological Research were led by river divers to an underwater site in the Apalachicola River containing a large concentration of prehistoric and historic artifacts lying on the riverbed. Subsequent inspection of the submerged river bank and scoured limestone river channel revealed a myriad of objects, which included iron fasteners, metal tools and implements, broken glass bottles, stone projectile points, scattered bricks and stone blocks, and other materials. Discovery of two large fragments of a wooden watercraft, a bayonet, a copper arrowhead, and flintlock gun barrels initially prompted researchers to hypothesize that the site might represent the remains of a U.S. Army boat that was attacked in 1817 by Seminole Indians while en route upriver. The episode, which caused the deaths of more than 30 soldiers and several women who were aboard the boat, led to the First Seminole War and the U.S. Army invasion of Florida. To investigate this hypothesis, a systematic survey of the riverbed was undertaken in the spring of 2002 to record underwater features and recover additional diagnostic artifacts. These activities employed side-scan sonar as well as diver visual investigations. This paper presents a case study of the value and broader significance of aggregate data where interpretation was underpinned by artefactual, historical and environmental analysis.  相似文献

Charcoal recovered from different archaeological excavations carried out in the Teotihuacan Valley, México was used to evaluate whether significant changes in the use of wood took place through time (approx. 400 B.C.–A.D. 1500). Sixteen taxa of trees and shrubs characteristic of the Basin of Mexico were identified (including Pinus, Quercus, Arbutus, Cupressaceae, Alnus, Prunus, Taxodium, Salix, Baccharis and Buddleia, among others). Variations in the proportions of taxa are interpreted as a reflection of the intensity of use rather than an indicator of deforestation. The analysis of the data shows a pattern of continuity in the utilization of taxa throughout the occupation. This includes the use of different vegetative parts (trunk and branches), genera and species with different life forms (trees, shrubs, herbaceous plants) and primary (Pinus and Quercus) as well as secondary taxa (Prunus and Arbutus). We propose that the inhabitants of the Teotihuacan Valley implemented practices to manage vegetation in order to assure resource availability in the region.  相似文献

Mollusks were an important component in the diet of the hunter-gatherer groups that inhabited the coastal zones of South America during the Holocene, as recorded in the littoral shell and archaeological sites distributed from Brazil to Argentina. Although the shells are relatively resistant to physical and chemical agents, they are also fragile and various post-depositional processes affect their integrity. Puente de Fierro is an archaeological site located in the south of Buenos Aires province (Argentina), in which remains of the yellow clam (Amarilladesma mactroides) were recovered totally fragmented. We investigate if a morphometric model based on modern clams could be applied to estimate shell size and individual biomass of archaeological clams. Linear regression models reveal a high correlation between the chondrophore length and the shell length, and therefore, the individual biomass of the yellow clam.  相似文献

Abstract

Tourism Geographies is a prominently ranked journal that emerged from activities of the Tourism Commission of the International Geographical Union. It is indexed in the ‘Tourism, Leisure and Hospitality Management’ and ‘Geography, Planning and Development’ fields in the Scopus database and published its 20th volume in 2018. A bibliometric assessment of the articles and authors who have contributed to Tourism Geographies over its first two decades highlights major trends and dominant issues covered by the journal’s content. Key indicators include the most published and most cited authors and articles, the institutions and countries that those authors are affiliated with, other academic journals that are closely linked to the journal through citations, and the most used keywords in the journal. The Scopus database provides access to these basic bibliometric data, while the VOSviewer software enables graphical analyses and displays of co-citations, co-occurrences of keywords, and bibliographic couplings (shared references) across papers and authors. Overall, Tourism Geographies is closely linked to other leading journals indexed by Scopus in the ‘Tourism’ and ‘Geography’ fields and publishes papers from around the world. Research topics that have been most prominent in the journal include tourism development, tourist destinations, tourist attractions, heritage tourism, tourism perceptions, sustainable tourism, and travel behavior. Among the most viewed individual papers have been those addressing issues related to sustainability, poverty issues (related to tourism in poor areas, volunteering, sustainable tourism, and the environment), and community planning (sustainable tourism planning, tourist routes and movement, and new locations for tourism development).  相似文献

Despite that the Badakhshan Province (Afghanistan) remains the most plausible hypothesis for the lapis lazuli used in antiquity, alternatives proposed in literature are worth to study to confirm or disprove their historical reliability. In this work, a protocol for determining the provenance of lapis lazuli rocks used for carved artefacts is described. Markers for the univocal attribution of the raw material to a source were identified analysing 45 rocks of known provenance (among which 15 georeferenced) from 4 quarry districts. To the best of our knowledge, this reference database is the widest in provenance studies on lapis lazuli. All the markers are recognisable by means of Ion Beam Analysis (IBA) techniques, in particular micro-proton-induced x-ray emission (PIXE) and micro-ionoluminescence (IL). These techniques are non-invasive and applicable in air, allowing to analyse artworks and rocks of practically any shape and dimension without sample preparation.The protocol was applied to determine the provenance of raw material used for carved lapis lazuli artefacts kept at the Egyptian Museum of Florence, the second most important Egyptian museum in Italy, second only to the museum of Turin. The collection in Florence has a great historical value and includes several lapis lazuli pendants, scarabs, small statuettes and amulets ascribable mainly to the first millennium BC. Following the protocol, 11 of these artefacts were analysed by means of IBA techniques. Results ascribe the raw material to the Afghan quarry district.  相似文献

This paper aims to study notable examples of transatlantic transmissions of norms, beliefs and values that have revised the sense of a Luso-Brazilian community in a global world. The so-called Atlantic Civilization understood before as essentially Anglo-Saxon, takes a new shape when seen by the South Atlantic. If the historical relationship between Portugal and Brazil was one of colonial containment, since the nineteenth century those bilateral relations have passed through a process of reconciliation and networking – first through a mutual acceptance, then through the establishment of common international goals. On the one hand, this networking between Portugal and Brazil has occurred through public symbolic demonstration and the commemoration of a common culture; on the other hand, this networking has evolved through cultural connections – music, literature, and cinema, – all of which serve to validate a postcolonial review. Cultural connections that have survived the proverbial test of time have proven to be valuable in assessing the evolving relationship between Portugal and Brazil. Therefore, the Brazilian conscientiousness of its importance in the regional and world sphere involved the preparation of a Brazilian cultural diplomacy that recognized the political desire of diplomacy between Portugal and Brazil – a diplomacy that is largely demonstrative of the importance of soft power in a world of global networks.  相似文献

Abstract

Observation of cause–effect patterns of change in coastal environments provides insights into vulnerable areas and supports prediction and adaptation to flooding and erosion. Historic and periodic (6–8 year intervals) imagery from the Landsat archive is used to investigate transformations in the Atlantic coast of two Scottish islands over the period 1989–2011. Supervised classification of spectrally normalized images followed by change detection and spatial analysis reveals the patterns of change and the location of the most dynamic coastal areas. Quantitative measures of recent shifts and movement rates of relevant coastal lines, such as the lower limit of land-based vegetation, are assessed with the Digital Shoreline Analysis System. While very low rates are indicated for horizontal changes in the position of the lower limit of land-based vegetation (0.3?m?y?1), specific areas have been subjected to high rates of coastal progradation as well as erosion (e.g. 2.5?m?y?1 at Stilligarry). Information derived from satellite data supports the characterization of geomorphologically dynamic coasts at regional scales. With a rich and open access archive of imagery, a commitment to continuity, and compatibility with the Earth observation missions of other space programs, the Landsat mission offers useful and otherwise unavailable data for monitoring of coastal areas.  相似文献

An integration of geophysical surveys, ground hyperspectral data, aerial photographs and high resolution satellite imagery for supporting archaeological investigations at the multi-component Vészt?-Mágor Tell, located in the southeastern Great Hungarian Plain, is presented in this study. This is one of the first times that all these techniques have been combined and evaluated for retrieving archaeological information. Geophysical explorations, specifically magnetic gradiometry and ground penetrating radar methods, have revealed shallow linear anomalies and curvilinear rings at the Tell. The use of remote sensing images has confirmed the diverse anomalies with respect to geophysics through photointerpretation, radiometric and spatial enhancements. Moreover, several indices from ground hyperspectral data also have revealed stress vegetation anomalies. These integrated results were used to map the main areas of archaeological interest at the Vészt?-Mágor Tell and plan future excavations. It was found that these multiscalar data can be used efficiently for detecting buried archaeological features.  相似文献
