The types and other specimens of Agnostus fallax Linnarsson 1869 are examined and reinterpreted. It is shown that the application of this specific name to many specimens from around the world is largely in error. The species is considered sufficiently different from the type species of Peronopsis, P. integra (Beyrich, 1845) to warrant erection of a new genus Axagnostus with A. fallax as the type species.  相似文献

Phosphate fillings of the tunnels made by endolithic micro-organisms in the shells of Early Cambrian molluscs have been observed on phosphatic internal moulds at several sites. The best preserved examples are from the shells of the gastropod Yuwenia bentleyi from the Parara Limestone of South Australia. Three distinct types of borings are found in these shells: long unbranched tunnels that are either about 10 µm or 3 µm in diameter, and short vertical holes. The nature and distribution of the borings suggest that they were made by photosynthetic algae rather than fungi.  相似文献

One of the biggest challenges for the East Asian region today is the Sino-Japanese relationship. Starting with the fishing trawler incident in September 2010, followed by Japan's nationalisation of the Senkaku/Diaoyu Islands, this relationship is experiencing an escalation of tensions in most, if not all, areas of the bilateral relationship. In response to the intensifying competition, China and Japan have elevated the importance of South-East Asia and the Association of Southeast Asian Nations (ASEAN) in their foreign policy strategies. Focusing on how elites from five South-East Asian states—Indonesia, Malaysia, the Philippines, Singapore and Vietnam—perceive the engagement of China and Japan with the region, this article poses two questions: (1) How do South-East Asian elites view the Sino-Japanese competition? and (2) How do South-East Asian elites view the role of ASEAN in managing the competition? The analysis here concludes that while some South-East Asian elites see opportunities in the Sino-Japanese competition, they nevertheless do not perceive it as an issue of critical significance. Instead, the concern lies generally with major-power dynamics, and particularly with Sino-US relations. ASEAN is viewed to lack the ability to manage the negative consequences of the Sino-Japanese competition, although its external balancing function has perceptibly helped to restrain any escalation of major-power tensions.  相似文献

瘟疫来自中国?——14世纪黑死病发源地问题研究述论   总被引:1,自引:0,他引:1  
根据德米西等人的记载以及考古学的发现,可以肯定黑死病自亚而欧的传播趋向。但在黑死病的发源地问题上,学者们颇有争论,特别是中国受到了较多的关注。但从词源学的角度来看,黑死病源于中国的论断很可能是个谣传。鼠疫自然疫源地在中亚地区自东而西连绵不绝的分布,使我们目前很难断定到底哪一处是瘟疫的发源地;而只有在断定了瘟疫在中亚各地爆发的时间次序,才有可能进一步考证其准确的发源地。从某种意义上说,整个中亚都是黑死病的发源地。  相似文献

Abstract

The energy and mineral resource base of Southeast Asia is relatively modest by international standards. Nevertheless, Chinese energy and mining companies have been investing heavily in the region over recent years, in comparison with multinational companies and state-backed companies from other Asian countries. This paper applies a framework derived from the field of business studies to analyze why the scale of China’s engagement in Southeast Asia has become so great and how the motivations vary between the different energy and resource industries. The motivations for these activities reflect a mix of corporate and state objectives. Corporate objectives include securing energy or resource supply chains, increasing or diversifying their asset base, and enhancing their profits or market share. The motivations of the government range from straightforward support of the companies for the purpose of industrial strategy and security of resource supply, to development assistance and regional strategic positioning. The different motivations of the oil and gas, hydropower, and mining industries arise from the particular character of each market, both within China and globally. Southeast Asia has the twin advantages of geographic and apparent cultural proximity to China. Nevertheless, inexperience and a desire to catch up with their international peers have resulted in companies applying low social and environmental standards in some high profile projects. The subsequent disputes, together with the current low level of resource prices, may constrain the further growth of Chinese investment in the near future.  相似文献

Zhuravlev, A. Yu., & Gravestock, D. I., 1994:03:28. Archaeayaths from Yorke Peninsula, South Australia and archaeocyathan Early Cambrian zonation. Alcheringa 18, 1–54. ISSN 0311-5518.

Two assemblages of archaeocyaths are documented from Lower Cambrian outcrops and drillholes on Yorke Peninsula. South Australia. The older assemblage (11 species) occurs in the uppermost Kulpara Formation and conformably overlying basal Parara Limestone, and is equivalent to Lower Faunal Assemblage II in the Flinders Ranges. The younger assemblage (28 species plus Acanthhcyathus and Rodiocyathus) occurs in the Koolywurtie Member near the top of the Parara Limestone. Equivalent taxa are widespread in the Flinders Ranges, western New South Wales and Antarctica. Archaeocyathan distribution is now sufficiently well known to propose three assemblage zones and two informal assemblages for regional correlation. No new taxa have been added, but Erugatocyathus scutatus (Hill) and Pycnoidocyathus latiloculatus (Hill), hitherto known only from Antarctica, are found in the upper assemblage on Yorke Peninsula. Irregular archaeocyathan systematics are discussed, the ontogeny of Archaeopharetra irregularis (Tylor) clarified, and Kruseicnema Debrenne. Gravestock & Zhuravlev, represented by K. gracilis (Gordon), is fully described.  相似文献

Microfossils which are hollow, possess a two-layered vesicle wall, and occur as single elements or, more rarely, as compound forms, have been recovered from the Early Cambrian Heatherdale Shale, on the Fleurieu Peninsula, South Australia. The microfossils, which range in size from 4 to 14.5 μm, are informally and tentatively assigned to the genus Sphaerocongregus Moorman 1974. Superficially they resemble forms assigned to Pyritosphaera Love 1958 and its probable junior synonym, Bavlinella Shepeleva 1962. Topotypes of these genera, however, have yet to be studied using SEM techniques, and their morphologic details remain uncertain. The organic composition of the present microfossils is supported by energy-dispersive X-ray analyses. Samples of the Heatherdale Shale were also analysed using pyrolysis techniques; the organic matter is, however, over-mature with respect to petroleum generation, and no geochemical assessment of original kerogen type is possible.  相似文献

Fu, Y., & Huang, D., December 2018. New sinoalids (Insecta: Hemiptera: Cercopoidea) from Middle to Upper Jurassic strata at Daohugou, Inner Mongolia, China. Alcheringa 43, 246–256. ISSN 0311-5518.

A new fossil genus with three species of Sinoalidae, Parasinoala daohugouensis gen. et sp. nov., Parasinoala minuta gen. et sp. nov., Parasinoala magnus gen. et sp. nov., from the Middle to Upper Jurassic Haifanggou Formation at Daohugou, Inner Mongolia, northeastern China, is described and illustrated. The new genus differs from other sinoalids by the tegmen with RA having 2–3 branches, MP with 3–4 branches and MP of hind wings with two branches, which indicates the terminal branches of RA and MP are highly variable within Sinoalidae. The new discovery greatly increases the palaeodiversity of sinoalids in the early assemblage of the Yanliao biota from the Daohugou beds.

Soaring prices for minerals and energy are posing a major threat to the resource security of economies in Asia. As a result, many regional governments have launched new resource security strategies in the last few years. Most recent attention to resource security in Asia has focused on debating whether the Chinese government’s resource policies are mercantilist or liberal. This China-focused debate is too narrow to fully capture the nature of resource politics in Northeast Asia, since the governments of Japan and Korea have also recently launched their own resource security strategies. This paper considers regional-level trends in Asian resource politics by examining the causes, content and implications of the resource security strategies deployed by the consumer governments in Northeast Asia. It argues that growing resource security concerns, combined with a process of competitive policy emulation, have seen the Chinese, Japanese and Korean governments each adopt mercantilist resource security strategies over the last decade. Furthermore, the competitive nature of these mercantilist strategies is acting to intensify political and economic competition for resources between the Asian region’s three main economic powers.  相似文献

地区史或区域史的研究应是世界史研究的一部分。在全球化的今天,世界历史的研究,既应是跨区域跨文化的综合整体研究,同时又是各个地区或区域研究的深入。在地区史研究中,地理上的划分是否能够提供一个满意体系,一直存有疑窦,而中亚史研究中更突出地存在着地理划分的争议。事实上,每一部有关中亚的著作都有自己的地理界定,不同的界定又体现出作者对自己所研究的地区的理解和期望,划定地域界限,就是确定、分析、重建,从而选择和采纳某种历史哲学。国内中亚区域史的研究,起步较晚,很大程度地受语言因素的制约,因此,在一些具体研究领域上,与国际最高水准还有不同程度的差距。  相似文献

Urbanism in the Indian subcontinent occurred in three distinct time periods in which cultural cohesion over large regions is archaeologically demonstrated through the architecture and artifacts of social, ritual, and economic activity. In the Indus (2500–1900 B.C.) and Early Historic (3rd century B.C. to 4th century A.D.) periods, cities were not necessarily tied to political territories or guided by strong political leaders, but by the Medieval period (after the 9th century A.D.), urban zones were the base for political growth, warfare, and aggrandizement. The comparison of these three eras is undertaken within a framework for defining cities that balances quantitative criteria such as population size and areal extent with two types of qualitative criteria: internal specialization on the basis of materials found within archaeological sites, and external specialization on the basis of data recovered through regional analysis. Cities from the three eras also are evaluated from the perspective of the ordinary inhabitant through the examination of the social, religious, and economic factors that prompted and rewarded urban residence. While the Indus and Early Historic cities were attractive because of the networks of opportunity found there, Medieval cities additionally benefitted from a “push” factor as ordinary inhabitants allied themselves to urban areas in times of political stress and uncertainty.
