1948年12月中国人民银行成立以来,作为中央银行,负有"发行的银行"、"政府的银行"、"银行的银行"三大基本职能。为完善人民银行这三大职能,中央政府在法规方面逐渐加强建设,从仅在政府组织法体现人民银行央行职能到改革开放后出台强化人民银行央行职能的条例,最终在20世纪末出台了专门的单行法——《中华人民共和国中国人民银行法》以及2003年的修订本,并为此制定了相应的行政法规与金融规章,构楚了我国中央银行法律体系的基本框架。在法规日渐完善的同时,人民银行在国民经济的宏观调控中发挥着越来越重要的作用。 相似文献

区域旅游发展格局形成要素及演变机制研究——以中部六省为例 总被引：4，自引：0，他引：4
在对区域旅游基本概念梳理的基础上,本文对区域旅游发展格局的要素选择方法和核心要素进行了分析,并以中部六省为例对区域旅游发展格局的形成要素和评价体系进行研究。本文认为,区域经济中的增长极开发模式、点-轴开发模式、核心-边缘开发模式、协作网络开发模式和竞合模式等是可以在区域旅游发展格局演变中借鉴和应用的模式。 相似文献

Just when molecular biology is arguably delivering on some of its long-promised medical applications—think mRNA vaccines, monoclonal antibody drugs, PCR testing, and gene therapies—the history of molecular biology has lost much of its shine. What not too long ago seemed like a burgeoning field of research with endless possibilities, is now often reduced to the “central dogma” that saw its apotheosis in the effort to sequence the human genome but has since unraveled. The essay will discuss several possible answers to this apparent paradox. 相似文献

Within Iran, there is little archaeological evidence for relationships between newly arrived Early Trans-Caucasian (ETC) or Kura-Araxes settlers and earlier inhabitants and contact with neighbouring cultures, or for their apparently abrupt end. Based on the evidence, the Iranian Kura-Araxes was not a simple ‘copy' of the Caucasian Kura-Araxes package. Ceramic traditions show local peculiarities, and all are elements suggesting that the Kura-Araxes traditions went through processes of adaptation, change and re-elaboration according to local tastes and technologies. In this study, an archaeometric approach to ceramics in the Kolyaei Plain of central Zagros contributes to the discussion of contact and exchange between indigenous communities and several cultural spheres of influence on the Early Bronze Age (beginning in the fourth millennium bce ). Morphological data, as well as the mineralogical and chemical composition of ceramics, were applied to determine the major and trace elements of the pottery shards. Based on the trace element profiles, it can be suggested that all the pottery shards are in the same group and they strongly are local products. The ceramic provenance indicates the same patterns of material interactions during the ETC or Kura-Araxes in all the sites within the Kolyaei Plain. 相似文献

This paper introduces the first results of the joint Omani-Italian archaeological project at Wādī Banī Ḫālid (northern Šarqiyyah governorate, eastern al-Ḥaǧar), where a dense Iron Age and ancient Islamic occupation was detected. The aim of the project is the definition of the Iron Age settlement patterns along the eastern al-Ḥaǧar landscape and its relationship with both the coastal areas and the al-Ḥaǧar inner piedmont sites of central Oman. In fact, this project follows previous studies of the coastal environment between Muscat and Raʾs al-Ḥadd, where several seasonal fishermen villages were investigated, and their connections with inner permanent sites, such as Lizq, recognised during the Early Iron Age II (1300–600 BCE). Therefore, Wādī Banī Ḫālid stands as a peculiar case of an Iron Age territorial unit, a natural scenario made of a narrow alluvial valley which provided natural conditions for the development of a complex culture. Moreover, the material culture emerged after a first excavation campaign proved that the main occupational phase of the imposing fortified settlement WBK1 is the Late Iron Age (late first millennium BCE to third–fourth centuries CE), thus hopefully allowing new questions to be posed for the definition of Late Iron Age cultures and the chronology in central Oman, which is mostly known based on the excavation of funerary evidence. For this reason, the first part of the paper focuses on the results of the first season in Wādī Banī Ḫālid, and the second part discusses the links between Wādī Banī Ḫālid and the south-eastern Arabia general framework during the Late Iron Age. 相似文献

Archaeological research in central‐northern Patagonia (Atlantic coast and lower the valley of Chubut river) showed that this area was used since at least the Middle Holocene. Stable isotope analyses (13C and 15N) of human bone samples indicate that hunter‐gatherers living in that area had a terrestrial‐marine diet including guanaco meat, land plants, mollusks and pinnipeds. Despite this general trend, intersite variability and changes through time were noted, especially after the late Holocene. These results have been reinforced by archaeofaunal, technological and bioarchaeological records. In this paper, three hypotheses are examined: (a) the diet of these populations was complete and rich enough to ensure good health status and avoid nutritional deficiencies; (b) carbohydrate consumption increased progressively after 1000 BP, when pottery technology was adopted and (c) this kind of mixed diet would have been qualitatively more nutritious than that of other populations of the region, which would have resulted in better nutritional and healthy conditions. These three hypotheses are compared with dental results obtained from 563 permanent teeth from 45 individuals (34 adults and 11 juveniles from both sexes), rescued from burial sites. Indicators of oral health were assessed through the observation of caries, abscesses, wear, pulpar cavity exposure and ante mortem loss. Features of nutritional status such as enamel hypoplasia, porotic hyperostosis and cribra orbitalia were also examined. Given the availability of direct radiocarbon dating for most of the sample, three temporal series were determined: ‘Before 1000 BP’, ‘1000–5000 BP’ and ‘Post‐contact’. No evidence of alimentary stress or iron deficiency was found in individuals from the three series, which accounts for healthy and good nutritional life conditions. After 1000 BP, the results show a progressive increase in the caries percentage and a decrease in abscesses, dental wear and ante mortem losses frequency. This is possibly related to more consumption of processed foods in the last 1000 years. These results were compared with similar studies based on samples from different environments and latitudes of Patagonia. Evidence suggests that mixed diets (marine‐terrestrial) would have been more appropriate and nutritionally complete than exclusively marine or terrestrial diets.

Abstract: This paper examines an apparent anomaly that lies at the heart of processes of financial exclusion within Britain. Given that the branch networks of banks and building societies have shrunk in size by about one‐third since 1989, a period during which the Government has launched a wide‐ranging set of policies to tackle financial exclusion, why is it that the issue of branch closure has been neutralised as a political issue? After providing evidence to show the extent of branch closure in Britain and illustrating the ways in which geographical research in particular has drawn attention to the nature of this problem, we look at the way the issue of physical access to financial services has been discursively and politically marginalised. We undertake a detailed history of public policy in the area, and the ways in which research funded by industry bodies and Government departments has been used and framed to build a pro‐market, neoliberal policy programme that constructs branch closures as natural and inevitable. 相似文献

Although big city growth was not officially favoured in the former socialist countries, big cities did grow fast. The existence and continuing growth of primate and large cities is typically attributed to urbanisation economies, diverging sectoral and spatial interests, and difficulties in managing such a complex process as migration. However, whether such developments are systemic to socialism or reflect universal urbanisation processes is an issue of continuing debate. This paper aims to add to this discussion, and it does so by subjecting it to an empirical test, namely that of Estonia. For this purpose the concept of differential urbanisation is employed, as this model explicitly attempts to bridge the gap between various types of economies and urban settlement networks in both developed and developing countries. 相似文献
