党的十一届三中全会之后,在世界形势发生深刻变化、和平与发展成为时代主题的历史条件下,邓小平集中全党和全国人民的智慧,从中国的实际出发,在充分尊重历史和现实的基础上,创造性地提出了"一个国家,两种制度"的科学构想.作为我国解决台湾、香港、澳门问题、实现祖国统一的一项基本国策,"一国两制"构想从提出到实践,都受到了广泛的关注,成为国内外学者研究的热门课题之一. 相似文献

Twenty‐six samples from domestic assemblages of 9th–12th century Córdoba were subjected to electron microprobe analysis. The results reveal two main compositional types. The first, encountered in 13 of the samples, seems to result from the combination of plant ashes with high‐impurity sand, and has some contemporary parallels from Syria and Egypt. The second type is a lead–soda–silica glass, encountered in a relatively high proportion of the glasses (11 of the 26 sampled), possibly formed by the addition of lead metal to existing glasses and with very few known parallels. These are among a very small number of results available to date on the chemical composition of glasses from medieval Spain, and the presence of a high proportion of lead–soda–silica glasses is particularly interesting, possibly indicating a technological practice unique to, or originating in, the western Muslim world. 相似文献

THE EFFECT OF ACCESSIBILITY ON PRODUCTIVITY IN SPANISH MANUFACTURING FIRMS 总被引:1,自引:0,他引:1 下载免费PDF全文
David Martín‐Barroso Juan A. Núñez‐Serrano Francisco J. Velázquez 《Journal of regional science》2015,55(5):708-735
This paper evaluates the impact of accessibility on the productivity of Spanish manufacturing firms. We suggest the use of accessibility indicators of workers and commodities, integrating transport, land use, and individual components, computing real distances or traveling times using the Spanish full road network. Estimated firms’ total factor productivity is explained as a function of the accessibility indicators and additional control variables. Results evidence the crucial role on firms’ productivity to the accessibility of commodities and to a slightly lesser extent the workers. 相似文献

Performance Goal Achievement in Fiscal Federalism: The Influence of State Partisan Environments and Regulatory Regimes 下载免费PDF全文
Jessica N. Terman 《政策研究杂志》2015,43(3):333-354
With tight budgets and hyper‐partisan interactions within and between the states and federal government, attention is being paid to the implementation of federal programs. This is particularly important because, as the recently implemented American Recovery and Reinvestment Act suggests, state administrators are often the implementers of federal policy. This study integrates the fiscal federalism literature with that on implementation and bureaucratic response to examine the effect that within‐state factors have on the degree of performance goal achievement in federally funded, state implemented programs. The findings suggest that, when implementing federal programs, state administrators face conflicting political incentive structures and policy‐specific capacity and capability deficits that influence their motivation and ability to achieve performance goals. 相似文献

以北京、武汉、西安城镇居民为例,探究旅游目的地选择行为的收入群体差异。研究发现,不同收入群体的旅游目的地选择行为存在明显差异,具体表现在:①不同收入群体的景区到访率均随距离的增加呈e指数衰减,但衰减速率存在收入群体差异,收入越高的群体,到访率距离衰减速率相对越小。②中国城镇居民的国内旅游目的地选择行为具有“距离择近,景点择高,经济择富”的“三择”倾向,但不同收入群体的“三择”程度不同,收入越低的群体,“距离择近,经济择富”的倾向越明显。③不同收入群体到访率空间分异趋势一致,但高到访率空间大小不同,收入越高的群体,高到访率空间越大。④目的地亲景度存在收入群体差异,收入越高的群体,目的地亲景度越高。 相似文献

Recent developments in evolutionary psychology expanding on signaling theory provide key insights to the connections between expressing social commitments and resource rights. Credibility enhancing displays (CREDs) are a means to convince individuals of commitment to belief systems and can link costly acts or extravagant displays to social success. In the Salish Sea, the transition from labrets to cranial modification from 3200 to 1000 BP has often been framed in terms reflecting a shift from achieved to ascribed social status. Other researchers have argued that labrets may reflect village scale identity not tied to political power. We suggest that an explicitly evolutionary approach provides novel insights into the changing material expressions of Coast Salish social commitments, specifically reciprocal resource access. The shift to cranial modification reflects increased CRED investment and cost, but not necessarily a transition towards ascribed status. Instead this shift may be changing expressions of the same forms of social commitments. 相似文献
