This article examines the wealthier inhabitants of Croydon in the late sixteenth and early seventeenth centuries, focusing on differences in wealth, ownership of property and social relationships. Using wills and subsidy lists, four broad categories of people were identified: gentlemen, yeomen, tradesmen and craftsmen and widows. There was no simple gradation of wealth between these groups; although gentlemen were generally among the richest subsidy payers, yeomen and tradesmen could also figure. In terms of social relationships and the ownership of property, there were differences. Gentlemen tended to marry within their own social group, appoint other gentlemen as overseers in their wills and were more likely to own land outside Croydon. The social relationships of yeomen and tradesmen/craftsmen were more focused on the town itself, as were their land purchases. Two groups of individuals can therefore be seen, not one homogenous entity as some scholars have argued.  相似文献

Resort-hotel location has diffused from the Northeast and Midwest to the Sunbelt and West. In 1985 there were approximately 834 resort hotels and 295,617 resort-hotel rooms in the United States. More than half of these rooms were located in just three states: Florida, Nevada, and Hawaii. The present distribution of resort-hotel rooms has been influenced by three periods in resort-hotel evolution. Until the early 20th century, resort hotels were in the tradition of the “Grand Hotel,” oriented toward natural resources in the East and Midwest and serving an elite clientele. Later in this period, elite resorts were also developed in the coastal Southeast and in the Southwest. A second, transitional period beginning in the 1920s accelerated construction of resort hotels in the Southwest and along the Southeastern coast. In the third period, post World War II mobility and affluence led to a revolution in resorthotel location and function. Resort hotels are now found in urban and suburban locations and have expanded the resort concept by linking it to meetings, conventions, and business travel. This has allowed resort hotels to adapt to changing market conditions and to achieve economies of scale by spreading demand throughout the year.  相似文献

Biodiversity assessment is considered a necessary activity in the planning of nature conservation. This activity is shown to gain authority by accessing an epistemic community of scientists and institutions. This is done through a process of socialization that includes the production of immutable mobiles and their circulation in networks only accessible through scientific practice. Local (non-scientific) modes of describing nature are shown to be capable of circulating in far-reaching but different networks. It is argued that the concept of biodiversity is culturally situated and yet the purpose of biodiversity assessment is to define territorialities across cultural divides. It can therefore be considered a post-colonial enterprise. It is suggested that a more hybrid view of nature is required and that biodiversity scientists have to be prepared to negotiate their representations of nature with those of other social groups.

La pratique et la diffusion de l'évaluation de la biodiversité dans le Mexique tropical

conservation, réseau, autorité épistémique, Oaxaca

L'évaluation de la biodiversité est reconnue comme une activité essentielle à la planification de la conservation de la nature. Il est établi que cette activité, en accédant à une communauté épistémique composée de scientifiques et d'institutions, jouit d'une plus grande autorité. Cela se produit par un processus de socialisation comprenant, entre autres, la production de mobiles immuables et leur diffusion à travers des réseaux accessible uniquement par la pratique scientifique. Il est démontré que les procédés locaux (non scientifiques) utilisés pour décrire la nature peuvent être diffusés à travers des réseaux vastes mais différents. Si le concept de la biodiversité est culturellement déterminé alors que le but de l'évaluation de la biodiversité est de définir des territoires au-delà des divisions culturelles, il est soutenu qu'il peut donc être considéré comme une démarche postcoloniale. Une perspective plus hybride sur la nature est proposée et les experts scientifiques en biodiversité doivent être disposés à négocier leurs représentations de la nature avec les membres d'autres groupes sociaux.

La práctica y circulación de la evaluación de biodiversidad en el trópico Mexicano

conservación, redes, autoridad epistémica, Oaxaca

La evaluación de biodiversidad se considera una actividad necesaria en la conservación de la naturaleza. Esta actividad gana autoridad por obtener acceso a una comunidad epistémica de científicos e instituciones. Lo hace mediante un proceso de socialización que incluye la producción de móviles inmutables y la circulación de ellos en redes accesibles exclusivamente por la práctica científica. Se demuestra que modos locales (no científicos) de describir la naturaleza son capazes de circular en redes distintas pero de gran alcance. Se sugiere que la noción de biodiversidad es cultural y, sin embargo, el objetivo de la evaluación de biodiversidad es el de definir características territoriales que cruzan líneas divisorias culturales. Por lo tanto, puede ser considerado una iniciativa pos-colonial. Se sugiere que hace falta una concepción más híbrida de la naturaleza y que los científicos en el campo de biodiversidad deberían estar preparados a negociar sus representaciones de la naturaleza con las de otros grupos sociales.  相似文献

Snow avalanche impact landforms (SAILs) are typically elliptical-shaped depressions bounded by an arcuate ridge located at the base of avalanche paths. The geomorphology of these features is controlled by the topography of the avalanche path, the availability of unconsolidated debris in the impact area and the ability of the avalanche impacts to displace the available debris in the direction of avalanche flow. Ground-based snow avalanches move debris by bulldozing, and airborne snow avalanches move sediment by excavation on impact .
This paper reports on the geomorphology, and surface age and stability of three SAILs in the southern Canadian Cordillera. Dendrochronology and lichenometry were used to date geomorphic activity at the sites. Evidence of present SAIL stability suggests they result from episodic, high-magnitude avalanche impact events over many hundreds of years. All three landforms share common morphologies: a water-filled bowl-shaped depression distally bounded by an arcuate ridge-oriented transverse to the avalanche path. Despite sharing many attributes, field investigations revealed that the origin of each SAIL was a function of the local variations in snow avalanche path topography and availability of unconsolidated debris in the impact area. The snow avalanche path associated with the Blackhorn site has a gentle gradient, which suggests that this SAIL is a result of ground-based avalanches. The SAIL at Spoon Lake appears to be a consequence of a resistant geologic feature that focuses snow avalanches in the impact area and results in explosive excavation. The morphology of the snow avalanche track at Peyto Lake causes large snow avalanches to become airborne prior to impacting and excavating an impact pool. All three SAILs examined in this paper are historically persistent landforms and these observations support previous findings indicating that SAILs require hundreds of years to develop .  相似文献

The site of Tula, Hidalgo, Mexico, is well known for its distinctive architecture and sculpture that came to light in excavations initiated some 70 years ago. Less well known is the extensive corpus of archaeological research conducted over the past several decades, revealing a city that at its height covered an area of c. 16 km2 and incorporated a remarkably diverse landscape of hills, plains, alluvial valleys, and marsh. Its dense, urban character is evident in excavations at over 22 localities that uncovered complex arrangements of residential compounds whose nondurable architecture left relatively few surface traces. Evidence of craft production includes lithic and ceramic production loci in specific sectors of the ancient city. Tula possessed a large and densely settled hinterland that apparently encompassed the surrounding region, including most of the Basin of Mexico, and its area of direct influence appears to have extended to the north as far as San Luís Potosí. Tula is believed to have originated as the center of a regional state that consolidated various Coyotlatelco polities and probably remnants of a previous Teotihuacan-controlled settlement system. Its pre-Aztec history exhibits notable continuity in settlement, ceramics, and monumental art and architecture. The nature of the subsequent Aztec occupation supports ethnohistorical and other archaeological evidence that Tula’s ruins were what the Aztecs called Tollan.  相似文献

Prior to Mexico's entry to the North American Free Trade Agreement (NAFTA), predictions of the consequent impact on the environment in that country ranged from the dire to very optimistic. This article investigates NAFTA's outcomes in terms of energy use and the emission of atmospheric pollutants. Specifically, has entry into NAFTA led to a convergence or divergence in indicators of emissions, environmental efficiency, and emissions‐specific technology in Mexico, the United States, and Canada? A battery of tests is applied to these indicators for energy use and carbon, sulfur, and NOx emissions in the three countries. The results show that the extreme predictions of the outcomes of NAFTA have not materialized. Rather, trends that were already present before the introduction of NAFTA continue and, in some cases, improve post‐NAFTA, but not yet in a dramatic way. There is strong evidence of convergence across the three countries toward a lower intensity of energy use and emissions per unit of GDP. Although intensity is rising initially for some variables in Mexico, it eventually begins to fall post‐NAFTA. Per capita emissions of sulfur and NOx also show convergence, but this is not the case for energy and carbon, and the latter variables also drift moderately upwards. The state of technology in energy efficiency and sulfur abatement is improving in all countries, although there is little, if any, sign of convergence and NAFTA has no effect on the rate of technology diffusion. However, total energy use and carbon emissions increase both pre‐ and post‐NAFTA and total NOx emissions increase in Mexico. Only total sulfur emissions are stable and falling in all three NAFTA partners.  相似文献

The manufacturing or distribution of pornographic materials was among the many crimes pursued by the Holy Office. Twenty-one denunciations of illicit sexual artwork from 1750 to 1820 are housed in Mexico's Archivo General de la Nación. The items range from illustrations and prints of men and women in sexualized poses to elaborate and ingenious etchings and paintings on watches and jewelry boxes. The protagonists in this article include denouncers, witnesses, and suspects, inquisitors, qualifiers, and other church agents, and producers, sellers, and consumers of prohibited artwork. These cases provide valuable information on the sexual culture of Mexico City's urban leisure class. Those accused of selling and purchasing illegal art did not view themselves as libertines or free thinkers who advocated sexual experimentation. Nor did they advocate anti-Christian or anti-establishment sentiments. Inquisitors did not demonstrate the same fears and anxieties about erotic drawings and artwork that they did with prohibited books, nor did they conflate eroticism and licentiousness with heresy and treason. The consumers of prohibited sexual artwork in late colonial Mexico City seem to have mostly reveled in the excitement of seeing and owning prohibited materials and sharing a good laugh with friends. Neither they nor inquisitors took these items too seriously.  相似文献

This paper reexamines some of the methods and craniometric findings in the classic volume The Ancient Inhabitants of Jebel Moya (Sudan) (1955) by Mukherjee, Rao & Trevor, in light of recent archaeological data and relative to a new dental morphological study. Archaeological evidence characterises these inhabitants as having been heavily influenced by outside sources; yet they managed to establish and maintain their own distinctive culture as seen in the site features and surviving artefact collections. The dental study, modelled after the original craniometric‐based investigation and using the same or similar comparative samples, detected complementary indications of outside biological influence. In the study, up to 36 dental traits were recorded in a total of 19 African samples. The most influential traits in driving inter‐sample variation were then identified, and phenetic affinities were calculated using the Mahalanobis D2 statistic for non‐metric traits. If phenetic similarity provides an estimate of genetic relatedness, these affinities, like the original craniometric findings, suggest that the Jebel Moyans exhibited a mosaic of features that are reminiscent of, yet distinct from, both sub‐Saharan and North African peoples. Together, these different lines of evidence correspond to portray the Jebel Moya populace as a uniform, although distinct, biocultural amalgam. Copyright © 2006 John Wiley & Sons, Ltd.  相似文献

Recent research in the Quijos and Cosanga valleys of the eastern piedmont of Ecuador’s Cordillera Real has revealed and substantiated previous knowledge of obsidian sources that are unrelated to obsidian flow systems in the Sierra de Guamaní, Ecuador. Neutron Activation Analysis (NAA) and X-ray Fluorescence (XRF) were carried out on 47 obsidian source samples collected from several contexts in and adjacent to the study area. From samples within the study area three distinct obsidians were characterized: Cosanga A, Cosanga B, and Bermejo. These obsidians originate from a number of obsidian-bearing rhyolitic domes recently identified in the hills west of the Río Cosanga. Extensive survey of these dome localities has identified obsidian cobbles large enough for formal and informal tool manufacture. Beyond the study area, samples were collected and analyzed from the El Tablón source in the Sierra de Guamaní, providing much needed data on this poorly understood source. In addition, a sample from the newly identified Conda Dome source, near the Cotopaxi volcano, was characterized with XRF. All samples were then compared to 57 pre-existing samples from the Mullumica–Callejones, Yanaurco–Quiscatola and Carboncillo sources in the Ecuadoran Cordillera Real, as well as to artifacts from the Sumaco area in the Ecuadorian Amazon. Results of the elemental characterization indicate that the Cosanga Valley, El Tablón and Conda Dome obsidians are chemically distinct. Further, visual characteristics of Cosanga Valley obsidian types are useful in source attribution for the large artifact samples from the region. Finally, obsidian collected from the El Tablón flow suggests that this source may have produced obsidian suitable for tool manufacture.  相似文献
