China is rising as the fastest growing largest economy and thereby leading a market-driven economic integration in East Asia. At the same time, nationalism is also rising and constraining East Asian countries from forming a state-driven regional community. This paper examines the political economy of interdependence and nationalism that is taking place in East Asia. Simply put, its central theme is that the degree of interdependence, especially between China and other countries, is deepening, and as a result, is pulling East Asia toward regional integration, but due to the rising tide of nationalism, it is far short of forming an actual community. In order to build a community, therefore, such economic trend must be propelled by political leadership and will. In elaborating on this thesis, the paper analyzes the trade and production networks centered on China, the efforts to promote regional integration in ASEAN?+?3, the nationalist rivalry between Japan and China in negotiating FTAs, and the difficulties in achieving Sino–Japanese reconciliation. Finally, the paper proposes a Northeast Asian Forum among Japan, South Korea and China while the US remains as a stabilizing force in East Asia. 相似文献

We investigate the role of payoff asymmetry in laboratory prisoner’s dilemma games. Symmetric and asymmetric games are examined in simultaneous and sequential settings. In the asymmetric sequential games, we study the impact of having payoff advantaged players moving either first or second. Asymmetry reduces the rates of cooperation in simultaneous games. In sequential games, asymmetry interacts with order of play such that the rate of cooperation is highest when payoff disadvantaged players move first. 相似文献

A sensitive analytical method was developed for the quantitative determination of tetrodotoxin (TTX), a powerful sodium channel blocker, in human postmortem whole blood. The sample mixture was cleaned up using cation exchange SPE catridge after protein precipitation by methanol and then separated on a PC-HILIC (phosphorylcholine hydrophilic interaction liquid chromatography) column (150 mm × 2.0mm i.d., 5 μm) using a isocratic elution of 1% acetic acid and acetonitrile. The identification of TTX was performed on tandem mass spectrometry with electrospray ionization interface in positive ion mode. The retention time of voglibose (internal standard) and TTX was 5.1 and 6.0 min, respectively. TTX and internal standard (voglibose) were monitored and quantitated using the ion transitions: the respective precursor to product ion combinations, m/z 320/302 for TTX and m/z 268/92 for voglibose in the multiple reaction monitoring (MRM) mode. The recovery of TTX and voglibose was 61.4% and 62.8%, respectively and the good accuracy (97.7-103.9%), linearity (2-1200 ng/mL) and reproducibility were shown in this method. The limit of detection and limit of quantification were 0.32 ng/mL and 1.08 ng/mL, respectively. This method was applied in the case of three fishermen who were poisoned (including one death) by unknown fish on their boat in October 2010. In this case, the levels of TTX were 27.2, 30.0 and 29.7 ng/mL in heart blood, peripheral blood and serum of a victim, were 3.1 and 12.1 ng/mL in peripheral blood and 3.9 and 12.8 ng/mL in serum of two survivors, respectively. 相似文献

The inefficiency of cooperative agriculture relative to private farms is often attributed to difficulties in monitoring or poor incentives. We develop a model to show that, in technologies with numerous sequential steps, even small shortfalls in worker effort can result in large output declines. Using data on cooperative and private farms in El Salvador, we find greater shortfalls in efficiency between cooperatives and private farms, as well as among cooperatives, for coffee, a crop requiring numerous steps in its cultivation, than for maize and sugar, which require fewer steps. Thus the undersupply of effort in cooperatives may be less than differences in productivity suggest, and cooperative agriculture is most likely to be successful where production does not involve many sequential steps. 相似文献

Abstract: The purpose of this study was to develop age‐predicting equations from the anterior cortex of the femur of Korean adults. Seventy‐two femoral samples (44 male and 28 female) were obtained from Korean cadavers and used to develop the equations. The thin sections (<100‐μm thick) were prepared by manual grinding; the sections were not decalcified and were stained with Villanueva bone stain reagent. Analysis of covariance showed no significant differences in age‐adjusted histomorphological variables between sexes. In stepwise regression analysis, osteon population density, average osteon area, and the most anterior cortical width were selected for an age‐predicting equation which produced a high regression correlation (R2 = 0.789). The average Haversian canal area was not significantly related to age for any specimen. 相似文献

Abstract: Meticulous recovery of victims in the Daegu subway disaster was possible, because charred and fragmented victims were left in situ. Because bodies were piled one over another within the train, appropriate methodology during the recovery was critical to identifying the victims. The disaster area was thoroughly documented with notes, photographs, and schematic drawings of the various locations. The recovery team, comprising two medical examiners and one forensic anthropologist, decided when charred body parts and cremated bones were linked to the same individual based on the anatomy and forensic anthropological examination. Without these recovery procedures, it would not have been possible to efficiently harvest representative DNA sample from most of the victims’ body parts. After the entire process of identification, 136 victims were positively identified, and six victims remained unidentified. This study supports the crucial role of forensic anthropologists in the recovery of victims, especially in fire scenes. 相似文献
