朝鲜古地图中保存了清代中朝边界的诸多重要信息。通过对多种朝鲜古地图的解读,考察了其绘制方法与特点,重点分析了穆克登碑、图们江源、"间岛"及鸭绿江下游岛屿等边界地区在地图上的表现方式与变化轨迹。可以看出,朝鲜古地图在绘制方法受到了中国传统舆图的深刻影响,在内容上反映了绘制者对本国历史、地理状况的认知,也体现了其领土观念与"北拓传统"。  相似文献

Song, J., Crasquin, S. & Gong, Y., September 2016. Ostracods of the Late Devonian Frasnian/Famennian transition from western Junggar, Xinjiang, NW China. Alcheringa 41, xxx–xxx. ISSN 0311-5518.

Ostracods are described for the first time from the Late Devonian of western Junggar in Xinjiang, NW China. Fifty-two species belonging to 30 genera are recognized, and seven are new: Arcuaria hebukesarensis sp. nov., Bairdia shaerbuertiensis sp. nov., Cribroconcha honggulelengensis sp. nov., Microchelinella bulongourensis sp. nov., M. hoxtolgayensis sp. nov., Pribylites wulankeshunensis sp. nov. and P. junggarensis sp. nov. The ostracod fauna indicates a probable late Frasnian age for the lower member of the Hongguleleng Formation, and the Frasnian/Famennian boundary may exist in the basal part of the formation. The ostracod assemblages are referable to the Eifelian Mega-Assemblage, incorporating both the palaeocopid and smooth-podocopid associations. The fauna implies deposition in a nearshore–offshore environment during a transgression when the lower member of the Hongguleleng Formation was being deposited in western Junggar.

The article explores the establishment of gendering divides in organisations by bridging Hernes' (2004) typologies of physical, social and mental boundary work with notions on the practice of gender as negotiated in everyday organisational activities. In the investigated Swedish supermarket, the pre-store, a narrow, front-stage space in which only women worked, was excluded from the job rotation that otherwise dominated the organisation of work in the store. This study examines: (1) how and on what grounds the divides of the pre-store were established in the supermarket and (2) how spatial divides were incorporated into the practice of gender and work in the supermarket. The findings suggest that the divides that are visible through the exclusion of the pre-store from the job rotation involved not only the allocation of work and space but also multiple and complex physical, social and mental spatial negotiations undertaken by both employees and managers. Together, these factors neutralised the divides as an aspect of the activities. First, the notion that gender was irrelevant for organisational decisions makes gender a non-issue for the organisation of the pre-store activities. Second, the notion that women and men are essentially different provided a ground for explaining why, despite being an organisational non-issue, work and workers were in fact organised along gendered lines in the supermarket. The study contributes with qualitative insights regarding the micro-political practices that make gender into a neutralised non-issue in organisations and, in particular, the intertwinement of spatial practices and negotiations.  相似文献

The British Isles are very rich, compared to the rest of Europe, in prehistoric boundary earthworks. There are difficulties in deducing prehistoric territories from them, mainly because of the incompleteness of other evidence of settlement patterns. Fortunately, in the past two decades there have been major advances in territorial studies, in particular, of the pattern defined by the reaves (long walls) on Dartmoor in Southwest England and in the Anglo-Saxon pattern in Southern England defined by boundaries in legal documents (charters). These studies enable some general principles of early land divisions to be deduced, particularly the relations of boundaries to the natural features of the terrain. These principles can be applied to the study of other early boundary earthworks, and, in some cases, reasonable deductions on the nature of the prehistoric estates can be made. The paper concludes with a discussion of major problems, namely, the dating of earthworks, the continuity of boundaries between prehistoric and historic eras, the functions of boundary markers, their chronological development, and their social implications.  相似文献

采用有毒化学药品防治动物标本害虫是博物馆使用的传统消杀方法。然而,考虑到化学药品对公众健康的潜在危害,迫切需要寻找更为安全的防治方法。采用安全无毒的-20℃低温冷冻法对标本害虫白腹皮蠹进行消杀实验,结果显示防治效果显著,寄生于动物标本皮毛的白腹皮蠹成虫在6小时内全部死亡。同时,研究结果还显示降温速度和标本制作材料的隔热特性是影响防治效果的重要因素。随着低温平衡时间的延长,害虫对低温冷冻的适应能力将逐渐增强,最终导致害虫消杀时间显著延长。此研究工作为博物馆采用安全无毒的低温冷冻法防治标本害虫提供了参考数据。  相似文献

生态税收是政府通过对破坏生态环境的行为(生产行为和消费行为)征收相应数量的税收,用于环境保护的投资或对保护环境的行为的税收支出,以保持生态平衡的一种税收体系。中国日趋严峻的生态环境、生态税制的缺位、可持续发展战略的实现以及提高公民环保意识迫切要求构建我国的生态税收体系。因此,制定完备的《生态税法》;改革旧税种,创立新税种完善税收体系;奖惩并重、税收征收与支出并举,就成为构建我国生态税制的基本思路。  相似文献

我国生产性服务业与经济发展关系研究   总被引:46,自引:1,他引:45  
钟韵  阎小培 《人文地理》2003,18(5):46-51
本文首先通过阐述我国经济结构的变化和目前生产性服务业的地位特征,分析我国生产性服务业发展与经济结构变化及经济发展水平的特征及关系,从而预测我国生产性服务业的发展潜力。然后针对我国经济发达地区,探讨生产性服务业对区域发展的作用。再以广州市为例,分析生产性服务业在城市发展中的地位及对区域的影响。试图从全国、区域以及城市三个层次对生产性服务业与经济发展关系进行研究。  相似文献

1644-1885年间,中越陆路边界桂粤段发生了多起领土争端,并引发了清朝与安南(越南)各王朝的边界交涉。本对这些争端和交涉的相关史实作了论述、分析,认为边境地区复杂的民族关系和两国统治对边疆领土的不同认识是影响交涉结果的主要因素。  相似文献

开封市产业空心化的历史考察   总被引:2,自引:0,他引:2  
无论发达国家或是发展中国家,都会面临着产业空心化问题。通过对开封市经济数据的分析及实地调研,发现开封市的产业空心化属于离制造业现象:经济地位明显下降,固定资产日渐减少,工业发展缓慢且结构不尽合理,第三产业比重低且结构失衡。指出开封市产业空心化具有欠发达区的共性特征-贫困恶性循环积累性,同时也是其特定的区位条件所引致的。最后提出开封市产业空心化的防治措施:以增强技术创新为核心,进行体制机制、科研体制、教育制度创新及人才的激励机制等;以需求结构变化为导向,调整、优化产业结构,加强财政、金融改革及基础设施的支持力度;加速完善硬件设施,改变市区的对外联系等。  相似文献

This article examines Canadian daily newspaper editors' views regarding the status of international news reporting in Canada. It is based on a series of surveys administered in 1988, 1995, 2000, and 2006 that measured editors' assessments of issues such as the quantity and quality of international news in their papers, the importance they attach to international news coverage, the areas of the world they consider important to cover, and the sources they use for international news. The article uses the data from the surveys to determine whether 11 September 2001 affected editors' perceptions of international news reporting. This question has been widely studied in the United States, but less so in Canada. The central conclusion here is that 9/11 has had only a limited impact on editors' perceptions. The data across all four surveys demonstrate a remarkable degree of consistency in editors' assessments of international news reporting in Canada.  相似文献
