东亚地区的相互依赖程度日益加深 ,为了促进东亚地区的贸易便捷化 ,使用信息和通讯技术工具构建电子贸易区成为一种必然。在东亚地区建立PAA等电子贸易区是可取的 ,为了建立电子贸易区 ,有必要改进电子商务的法律和税收制度。为了准备对电子商务进行税收激励 ,政府必须营造出一种能够使电子商务得以蓬勃发展的财政氛围 ,而不必单纯考虑其维护公平、可预测的税收体系的职责  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

Both adolescent and parental perceptions of how family members interact with and feel about one another are examined to determine their relationship to official and self-reported delinquent behavior. Consistent with prior research, adolescent perceptions of family processes were weakly related to those of their parents. Both parental and adolescent family process measures made independent and significant contributions to the explanation of self-reported and official delinquent behavior. Parental measures contributed more to the explanation of official data than did adolescent measures when compared to the results for self-reported delinquency. Methodological and substantive reasons for these findings are discussed. The importance of taking into account parental perceptions of family interaction, as well as the perceptions of adolescents, is emphasized.  相似文献

A number of DNA marker types suitable for human identification and parentage testing have been developed, of which single nucleotide polymorphisms (SNPs) merit attention as they are abundant, genetically stable, and amenable to high-throughput automated analysis. In this regard, 24 highly informative SNP markers representing each 22 autosome and both sex chromosomes were selected, and the allele and genotype frequencies of these SNPs were determined in a group composed of 30 unrelated Koreans. Based on frequency data from this group, the estimated probability of identity (P(I)) and probability of paternity exclusion (P(E)) with 22 autosomal SNP loci were 1.905x10(-10) and 98.9%, respectively. The SNPs in this study offer a small but highly accurate database that will be an essential reference for SNP-based forensic application in the future.  相似文献

The metabolite-to-parent drug ratios were determined in the hair of 2444 methamphetamine (MA) abusers who had produced MA-positive hair results from 2001 to May 2005 and in the hair of 53 ecstasy abusers who had produced positive methylenedioxymethamphetamine (MDMA) hair results from 2002 to May 2005. For the hair analyses, hair strands were washed, cut into small pieces and extracted for 20 h in 1 mL methanol containing 1% HCl. Drugs in the extract were determined by gas chromatography-mass spectrometry (GC-MS) using selective ion monitoring after derivatization with trifluoroacetic anhydride. The six range groups were divided as follows on the basis of MA concentrations in hair (n = 2389): 0.5-5 ng/mg (n = 950), 5-10 ng/mg (n = 582), 10-20 ng/mg (n = 503), 20-30 ng/mg (n = 160), 30-40 ng/mg (n = 80), more than 40 ng/mg (n = 114) to assess the correlations between MA concentrations and metabolite-to-parent drug ratios. In groups of higher MA concentrations, lower ratios of AP/MA were found, and there was a statistically significant difference among six range groups. Comparisons of age groups (tens, twenties, thirties, forties, fifties, and sixties) and male and female subjects for the ratios of AP/MA showed a statistically significant difference. The detection of metabolites and the parent drug with reasonable ratios was found to be a useful indicator for distinguishing internal drug incorporation from external contamination. In our study, MA users can produce 0.4-116% (mean = 9%) of amphetamine (AP) concentrations in hair, and ecstasy users 1-110% (mean = 12%) of methylenedioxyamphetamine (MDA) in appropriately washed hair samples.  相似文献

The civic education policy at the school level in Hong Kong had emerged before the Second World War, but the Hong Kong Education Department did not really implement this civic education policy. From the statist and colonial perspectives, this phenomenon was due to several factors, such as: (1) how the Hong Kong Government coped with the whole historical period and scenarios; (2) how it implemented the related policy; (3) whether civic education policy really became part of the government agendas; and (4) whether education did clarify some crucial historical questions. This paper wants to make certain about these questions. In fact, the Republic of China adopted modern schooling system which civic education was one of school subject. But it was not the education policy of the colonial Hong Kong Government. Historical reasons about this issue require reconstructive explanation. Under this study, the understanding of misinterpreted history can be amended correctly.  相似文献

The Cathay Organisation was a household name in the Chinese film industry. At its peak, it operated 75 cinemas and two movie studios, with a film distribution network spanning Malaysia, Burma, Thailand, Vietnam, Hong Kong, and Taiwan, as well as Europe and Latin America. In the public’s mind, Cathay was synonymous with its charismatic founder, Loke Wan Tho (1915–1964). Well versed in literature and ornithology, Loke appeared as a British gentleman, always meticulously dressed and elegantly mannered in his dealings with political leaders and movie celebrities. But underneath its gracious surface, Cathay was constantly struggling to sustain itself against problems that arose due to its rapid expansion. Although Cathay often produced impressive movies with graceful stars, high production costs could not be supported by the box-office revenues. By tracing the transformation of Cathay, this article will examine the dynamics of a Chinese family business in its attempt to survive amidst political chaos in Southeast Asia. Surviving generational succession, corporate consolidation and waves of political crises, Cathay’s story not only mirrors the transformation of an overseas Chinese family business over the past 100 years but also reflects a larger historical picture.  相似文献
