“合”与“分”的地理效应及民族个性差异   总被引:1,自引:1,他引:0  
本文从人文地理学的角度剖析了地理环境对于中国历史上国家统一与分裂的重大影响,暨阐述了通常所说的自然与人文的历史的辩证的关系。高山大川的“长城效应”与各区域民族个性差异形成对国家统一的威胁。但同时也是多民族国家统一体的再造与地域文化发展的前提条件之一。  相似文献

The Emerald site, also known as the Emerald Acropolis, was an early Mississippian pilgrimage center key to Cahokia’s development. This paper presents the hitherto unpublished results of two archaeological projects conducted at the site, one led by Howard Winters and Stuart Struever in 1961 and the other by Robert Hall in 1964. These investigations produced the most comprehensive information on Emerald’s Moorehead phase (1200–1300 CE) occupation, during which two of its mounds were capped, a secondary mound was constructed on the central mound, and a mound-top structure was erected on this secondary mound. Similar activities took place throughout the region during the thirteenth century, a time marked by dramatic social, political, and religious change in Greater Cahokia. Based on these data, we argue that people returned to Emerald to memorialize or draw on the powers inherent there and thus reincorporate this place into the newly imagined thirteenth century Cahokian world.  相似文献

The original ceramics typology developed for Younge/Western Basin Tradition Springwells phase (ca. AD 1160–1420) assemblages included three variants known as Macomb Linear, Macomb Interrupted Linear, and Springwells Net Impressed ceramics. This discussion considers how subregional variation in Springwells decorative styles reflects participation in a larger regional social network.  相似文献

战后,日本通过《日本国宪法》确立了资产阶级民主制度的三权分立之原则和形式,但由于世界范围内的趋势、日本政体的问题和自民党的"一党独大"等原因,遂造成三权失衡即行政权急剧膨胀和立法权与司法权遭到严重削弱诸问题。  相似文献

在中国古代,主要是通过科举制度选拔国家官员。科举制度废除后,孙中山主张在五权宪法的框架之中,由国家设置考试院,主管文官的选拔、任用和考绩。这一创新的理论实践于民国时期。在民国时期,文官考试制度开始运作和完善,其中的特种考试和检定考试是我国的独特创制。文官的任用、考绩、升调、奖惩、抚恤等制度称作文官"铨叙"制度,与文官考试制度相辅相成。文官"铨叙"制度最为规范,也是我国的独特创制。  相似文献

日本右翼势力对“台独”的支持大体经历了三个时期:战后初期,日本右翼势力是“台独”逆流的始作俑者和首开“台独”运动先河的罪魁祸首;冷战时期,日本右翼势力不仅在中日复交前使本国成为“台独”势力的大本营,而且在中日复交后仍一如既往、不遗余力地支持“台独”;后冷战时期,日本右翼势力支持“台独”不仅变本加厉,而且呈现出民间与政界配合、右翼与政府呼应之特点。  相似文献

Granitoid (pegmatite and aplite) veins in metamorphic rocks and intrusive syenites of central Dronning Maud Land, Antarctica, are flanked by conspicuous light‐coloured alteration halos, which represent the damage zone of fracture propagation. The damage zone is characterized by a high density of sealed or healed microcracks, about 1 order of magnitude above background. Fluid inclusions along healed microcracks in quartz of both pegmatite and alteration halos are inspected by optical and scanning electron microscopy, and their composition is analysed by microthermometry and quadrupole mass spectrometry. The similar inclusion record in the granitoid vein and in the damaged host rock indicates the derivation of the fluids from the hydrous melt phase. The aqueous inclusions bear abundant daughter crystals, mainly silicates, and may represent a hydrous melt. The volatile composition is variable in the system H2O–CO2, with mostly subordinate amounts of N2. Phase separation with partitioning of CO2 into the fluid phase coexisting with the hydrous melt, and possibly immiscibility in the subsolidus range, govern fluid evolution during cooling. The variable CO2/N2 ratio suggests mixing with fluids from an external source in the host rock and vigorous circulation at an early stage of high transient permeability. Experiments have shown that healing of microcracks at high temperatures is a matter of hours to weeks, hence similar in time scale to the cooling of the cm‐ to dm‐thick granitoid veins. In this case, rapid cooling and concomitant crack healing in a system undergoing phase separation causes a broad compositional variability of the inclusions due to necking down, and the underpressure developing in closed compartments precludes a meaningful thermobarometric interpretation.  相似文献

16-18世纪英国宪制和宪制思想演进   总被引:2,自引:1,他引:1  
阎照祥 《史学集刊》2006,2(4):51-59
英国16-18世纪宪制的演变比较曲折。内战前混合宪制已形成多年,其相应思想长期流行并影响后世。17世纪中期共和国的兴衰和分权制有名无实,给后人留下经验和教训。贵族寡头权力垄断和内阁制的形成发展,增强了18世纪英国混合制的特色。  相似文献
