《资本论》详细研究了工人阶级的现状、历史使命、未来发展,以及工人阶级解放的条件等,并且还为之提供了科学的理论指导.马克思当年所提出的关于人的解放的历史任务我们至今并没有完全解决.近年来,我们党提出的科学发展观和关于建设社会主义和谐社会的科学构想,就其精神实质来说,就是为了人的解放和人的发展.因此,马克思关于人的解放的学说仍然是指导我们今天实践的根本指导思想.  相似文献

Policy instruments for curbing CO2 emissions: The case of the Netherlands   总被引:2,自引:1,他引:1  
Taxes may seem to be the most attractive instrument for curbing the emissions of carbon dioxide. This paper, however, argues that environmental taxes involve a number of serious complications — especially in an open economy riddled with market imperfections like the Netherlands. Therefore, a wide-ranging policy mix is called for. As far as households and sheltered sectors are concerned, regulation can continue to play a major role. Within the context of unilateral policies aimed at exposed sectors, the combination of subsidies and voluntary agreements may be more cost effective than the tax instrument.This paper was prepared for a conference on Energy Taxation in Europe organized by the Stichting voor Economisch Onderzoek (SEO) and held on December 13, 1991 in Amsterdam, the Netherlands. The author would like to thank Sijbren Cnossen, Jarig van Sinderen and one anonymous referee for helpful comments on an earlier draft.  相似文献

Natural vegetation enhances the value of agricultural landscapes for people and wildlife. However, the role of anthropogenic versus topographic factors in driving the extent of natural vegetation cover within agricultural lands at large spatial scales remains unexplored. I assessed the influence of anthropogenic and topographic variables on the extent of agricultural mosaics with high natural vegetation cover in the country of Turkey where a large extent of natural and semi-natural vegetation is maintained by traditional agriculture. GIS layers depicting human land use, elevation, slope, roads and population data were obtained and summarized at two spatial scales, within provinces and for 100 km2 grid cells covering the country’s entire agricultural land area. Average farm size was also obtained at province level. Hierarchical Partitioning was conducted to determine the independent effect of anthropogenic and topographic variables on the variation in agriculture with high natural vegetation. Slope had the largest independent effect on the variation in the proportion of agricultural mosaic with high natural vegetation cover. The extent of agricultural and settlement area also explained much of the variation in natural vegetation across both grid cells and provinces. The proportion of natural vegetation increased as human population and road density decreased across grid cells and as average farm size decreased across provinces. These results suggest that while topography is the primary driver of natural vegetation cover within agricultural mosaics in Turkey, the pressures associated with urban development and agricultural industrialization may also influence the cultural and wildlife value of agricultural landscapes.  相似文献

This article examines changing architecture in Itacaré, Brazil, as it transitions from a fishing village to an international tourist destination. Tourism, as an assemblage of practices and perspectives, recreates places in specific ways that structure social and environmental relationships. Through an examination of historical architectural styles, tourist architecture, and popular architecture in Itacaré, this article analyses the ways a tourist economy has physically and socially rebuilt the city. Socially, the changing architecture marks and creates differences between class, racial, and regional identities while also providing an idiom through which public conversations about these changing economic systems and demographics are articulated. At the same time, the expansion of the city has led to racial-, regional-, and class-based segregation. Environmentally, tourist architecture creates new relationships to nature through re-imagining Itacaré’s position in relation to other rural and urban places and a new emphasis on the aesthetic value of nature.  相似文献

Protected areas are key to the conservation of global biodiversity and ecosystem services; however, their success is contingent upon adequate funding. One possibility to increase funding for park management is to “sell” a wider suite of ecosystem services “produced” by protected areas, such as carbon sequestration. We conducted 420 tourist surveys to analyze willingness to pay (WTP) for ecosystem service benefits via a conservation fee in the Tambopata National Reserve in Peru. We also interviewed eight tour operators about their perceptions of the proposed fee. The average stated WTP was 15 USD. Sixty-six percent of tourists stated they would pay 10 USD or more, which, if actually paid, would have resulted in 318,000 USD for park management in 2015. Most respondents stated they would pay an additional fee if it supported biodiversity conservation or local ecosystem services, such as water, but less than 10% of tourists were motivated by carbon sequestration as a reason to pay the fee. Most tour operators supported the additional fee. Our findings suggest that tourists are willing to pay higher fees to support conservation but that interest in paying for additional ecosystem services from parks may not extend to global and intangible benefits such as carbon sequestration.  相似文献
