Rural settlements growing crops and rearing animals are known as estancias in several South American countries. They played a prevailing role in the political and economic history of Argentina, particularly during the second half of the 19th century and the beginning of the 20th century. At present, many estancias are developing alternative activities, as recreation and tourism, in order to be able to subsist. The main problem lies in the fact that a non‐sustainable activity, frequently focused on the greatest economic yield, leads to the destruction of the heritage, instead of achieving its long‐term conservation. The purpose of this paper is to develop and verify a suitable model for the planning, execution and management of recreational and tourist activities in these rural settlements. As regards the scope of the concept of sustainable development, this methodology aims at achieving a balance between the recreational and tourist operation and the conservation of the rich heritage concerned. 相似文献

House societies have become popular with archaeologists in recent years, due to (among other things) their conspicuous material basis (wealth, heirlooms and the houses themselves). As yet, however, most archaeological studies have focused only on individual societies. In this article, we offer a comparative and long-term approach to the phenomenon, using as case studies the Bronze Age and Iron Age communities of the Levant, the Aegean and the central Mediterranean. We describe the elements that define them as house societies and examine their evolution through time. We follow a strictly Lévi-Straussian definition of the house that prevents the concept from losing heuristic power. Using this definition, we consider that houses are to be found in ranked societies without centralization and in complex agropastoral systems, like those of the Mediterranean, where agricultural soil is scarce and liable to be monopolized. We argue that the house emerges in these competitive contexts as an institution to control land and retain patrimony undivided. Through a combination of archaeological and written sources, we try to demonstrate that it is possible to document several strategies used by house societies to acquire and retain power and wealth, including dowry, levirate, a bilateral system of marriage alliances, ancestor cults, specific architectures and house treasures. The case studies addressed here offer good comparative material for assessing similar processes elsewhere. At the same time, we argue that the Mediterranean area developed a particular ideology, that of the shepherd ruler, that was essential to legitimate the house. 相似文献

This study focused on the spatial evolution of COVID-19 in the state of Chihuahua, Mexico. Data were retrieved from governmental databases and analyzed by means of GIS, applying the inverse distance weighted (IDW) method. The period of December 2019 through November 2021 was split into eight seasons. The root mean square error (RMSE) was used to assess the reliability of the interpolations, showing acceptable values (RSME < 25). During the period, the municipalities of Juarez and Chihuahua reached the highest number of confirmed cases and deaths, Juarez being the main hotspot of contagion (37.2% of confirmed cases; 46.9% of deaths). Four waves of contagion were identified during the evaluated period, with Fall 2020 being the strongest season. Since Fall 2020, the spread of the disease was more often observed in municipalities with the highest human mobility. Although the spread of COVID-19 decreased after Spring 2021, in Fall 2021 records indicated a continuous increase in cases in the state. That could be due to a relaxation of the implementation of sanitary measures, as well as to the propagation of novel COVID-19 variants having an elevated infectious level. Geospatial techniques allowed for an understanding of the spatial spread of COVID-19 and could be useful for its control. 相似文献

Using data on Italian cities, we document that over the period of 2001–2011, the number of establishments and employment in some key service industries are positively related to the inflow of tourists. We then build a general equilibrium model of small open cities encompassing these empirical features to study the impact of tourism on endogenous consumption amenities, factors’ allocation across sectors, prices, and welfare. We also study the interplay of exogenous historical amenities, tourism, and residents welfare in a system of two cities. When residents are immobile, they are unambiguously better off when they live in a city with richer historical amenities, and thus more tourists, than the other city. When residents are mobile and their welfare is equalized between cities, the strength of consumption amenities becomes crucial to determine whether they are better off living in an urban system where cities are heterogeneous or similar in terms of historical amenities. 相似文献

In order to assess the response of the radial growth of Pinus pinea L. to climatic variability in Central Italy, dendrochronological and dendroclimatological analyses were carried out on five different populations scattered along the Tyrrhenian coasts of the peninsula. The aim of this study is to contribute to the understanding of the ecological demands of this species, particularly in the study area. For each site total ring, early-, and late-wood width chronologies were developed. Multidimensional analyses were performed for the three tree-ring datasets in order to analyze the relations between sites chronologies. Both Principal Component Analyses and hierarchical classifications highlighted an important difference of one site in respect to the other, probably due to site characteristics. Correlation functions were performed to infer the main climatic factors controlling the radial growth of the species. For a comparative study, we limited our attention to the common interval 1926–2003 (78 years) in which the response of the tree-ring chronologies to climate at both local and regional scale was investigated. Positive moisture balance in the late spring-summer period of the year of growth is the climatic driver of P. pinea radial growth in the study area. Moreover, this study shows how low summer temperatures strongly favor the radial growth of the species. 相似文献

ABSTRACTWe study regional patterns of scientific knowledge production in Europe using all scientific publications in the period 2000–2014 attributed to 813 scientific subfields. We show that the existing scientific portfolio of regions offers opportunities for related diversification and discourages the creation of knowledge on topics unrelated to the local knowledge base. Many lagging regions show clear growth, but complex knowledge production remains highly concentrated in regions in the North and West of Europe. For lagging regions there are advantages in not specializing too soon and to first diversify before moving into developing more complex knowledge. 相似文献

The Programa Bolsa Família (PBF) is one of the largest conditional cash transfer (CCT) programmes in the world. CCTs have been described as a ‘magic bullet’ for development, and PBF is widely regarded as an exemplary programme. Examination of its conceptual underpinnings, features, impact and limitations shows that PBF provides substantial income support to the poorest. However, PBF is also self‐limiting and it can offer only limited long‐term gains to the poor. More significant outcomes require the expansion of the scope of PBF and other social programmes towards the universalization and decommodification of social provision in Brazil. 相似文献
