A new dysagrionid damselfly (Odonata: Zygoptera: Palaeodysagrion) from mid-Cretaceous Burmese amber

AUTHOR, N. &; AUTHOR, P. December 2017. Article title. Alcheringa 42, 301-305. ISSN 0311-5518. Dysagrionidae are common in Paleogene sedimentary rocks, but rarely recorded in the Mesozoic. This family, however, is diverse in Burmese amber. A new dysagrionid damselfly, Palaeodysagrion youlini Zheng, Chang &; Chang sp. nov., is described here based on a well-preserved specimen (holotype) in Burmese amber. The new damselfly provides wing apex and body characters for Palaeodysagrion. It differs from Palaeodysagrion cretacia in having Arc slightly distal of Ax2, the midfork slightly basal of the nodus, Cr and Sn almost perpendicular to RA and RP and in having a simple wing system. This is the fourth dysagrionid damselfly described from the Burmese amber.

Ectopic paragonimiasis from 400-year-old female mummy of Korea

Of the parasite eggs discovered in ancient samples from Korean archaeological sites, Paragonimus spp. are of particular importance in that they are regarded as one of the most insidious trematode infection sources. Although their infection prevalence decreased rapidly in the early 20th century, archaeoparasitological studies on the species are still required, as historical knowledge of paragonimiasis remains far from comprehensive. Fortunately, we recently were given a chance to examine a medieval Korean mummy in a good state of preservation. Using morphological techniques, we discovered evidence of ectopic paragonimiasis in the sample from the 17th-century female. When the ITS 2 gene was extracted, amplified and sequenced from Paragonimus eggs, it showed 100% homology to the sequences of modern Paragonimus westermani reported from Korea and Japan, forming a cluster distinct from South Asian P. westermani. Our report is the first-ever analysis of ancient Paragonimus DNA from any archaeological field in the world. The ectopic paragonimiasis diagnosis made in this study, especially involving the liver sample, also is the first of its kind in archaeoparasitology.

Shock Response from Pseudodynamic Test Using Momentum Equations of Motion

The feasibility of using pseudodynamic techniques to yield shock responses from impulses is studied herein. A direct integration method is often used to solve the force equation of motion in performing a conventional pseudodynamic test. However, this technique might not be applicable to obtain an accurate shock response from an impulse as a load discontinuity occurs at the end of the impulse. This is because this discontinuity will lead to an extra amplitude distortion and the amount of this amplitude distortion is increased with the increase of time step. Hence, a small time step is needed to reduce the extra amplitude distortion and thus the displacement increment for each time step might be smaller than or as small as the resolution of the displacement transducer. As a result, the displacement increment cannot be accurately imposed upon the specimen and the responses will be contaminated by the noise. In addition, the test duration is drastically increased. Alternatively, this difficulty might be overcome if the momentum equation of motion instead of the force equation of motion is solved pseudodynamically. Hence, an external momentum is used in the solution of the momentum equation of motion. Since the external momentum is a resultant of the time integration of the external force the discontinuity problem will automatically disappear. Consequently, reliable shock responses can be obtained from pseudodynamic tests.     

FDI and Local Economic Development: The Case of Taiwanese Investment in Kunshan

The extent to which foreign direct investment (FDI) can foster the long-term economic development of lagging regions remains a highly debated issue in the literature, even in the current era of intense territorial competition for mobile investment and resources. The emergence of new industrial spaces in China that have flourished through FDI offers a good opportunity to revisit the topic. Kunshan in Suzhou, China has evolved from an impoverished area into a world-class information technology (IT) centre within 25 years. FDI, mainly from Taiwan, has enabled Kunshan to gradually upgrade its economy, following a development path that has been largely based on the transplant of entire production chains from Taiwan. Local innovative strategies for attracting and increasing the embeddedness of Taiwanese FDI are also an important element of Kunshan's success. This paper discusses the positive aspects, as well as the potential costs and negative facets, of FDI in Kunshan, with the view to draw some policy lessons regarding the impact of FDI on the economic development of lagging regions.

试论河北补要村遗址仰韶文化晚期遗存

长期以来,由于材料的局限,人们对冀中南地区仰韶晚期考古学文化面貌的认识是较为模糊的。20世纪80年代,有学者曾将这一时期该地区的考古学文化暂且归属于仰韶文化大司空类型[1],以当时可见的材料,最大限度并具高度概括性地描述了冀中南地区仰韶文化晚期的文化面貌。随着资料的     

Confucian China and Jeffersonian America: Beyond Liberal Democracy

This paper begins by reviewing the ancient Chinese worldview, one imbued with cultural particularism wherein the Middle Kingdom identified itself as the centre of the universe. I then distinguish the ways in which historically the Confucian East and Christian West have respectively exerted cultural hegemony. I next analyse China's rebuffing of liberal democracy, and how the CCP's retention of one-party rule has generated concerns about its legitimacy. I conclude by showing that China and America each possess moral traditions – specifically Confucianism and Jeffersonian Deism – that have overlapping outlooks. Both maintain a worldview that disavows extremism. Based on this broader philosophical-religious analysis, I argue that contentions over liberal democracy notwithstanding, China and America share moral ideals vital for confronting some of today's exigencies.
