Traditionally, it has been argued that increased economic competition through free trade agreements would bring about environmental degradation. This study, however, argues that recent international free trade agreements have tended to enhance environmental cooperation among participating countries. This study has examined the process by which East Asian countries have developed mechanisms for the extant level of regional environmental cooperation, particularly highlighting the reasons for commonalities and differences in regional environmental cooperation between ASEAN and the dominant economies in the region. It finds that three factors particularly matter for developing regional environmental cooperative mechanisms: networks of intergovernmental organizations, the strong willingness of political leaders which is often embodied in national strategies for regionalism and the establishment, and the institutionalized linkage—particularly through FTAs—between trade and the environment. Tracing the process of policy evolution within three groups of countries sheds light on the political conditions under which the four entities involved (the ASEAN, Japan, China, and the Republic of Korea) have produced and strengthened cooperative environmental mechanisms among them along with free trade agreements. Focusing especially on the environmental policy changes in Japan, China, and the ROK associated with the creation of its FTAs with ASEAN, the study concludes that each of free trade agreements has incrementally developed environmental cooperation, especially when integrated into a vision for regional integration.  相似文献

Abstract:  Calliphorinae fly species are important indicators of the postmortem interval especially during early spring and late fall in Korea. Although nucleotide sequences of various Calliphorinae fly species are available, there has been no research on the cytochrome c oxidase subunit I (COI) nucleotide sequences of Korean Calliphorinae flies. Here, we report the full-length sequences of the COI gene of four Calliphorinae fly species collected in Korea (five individuals of Calliphora vicina , five Calliphora lata , four Triceratopyga calliphoroides and three Aldrichina grahami ). Each COI gene was amplified by polymerase chain reaction and directly sequenced and the resulting nucleotide sequences were aligned and analyzed by MEGA4 software. The results indicate that COI nucleotide sequences can be used to distinguish between these four species. Our phylogenetic result coincides with recent taxonomic views on the subfamily Calliphorinae in that the genera Aldrichina and Triceratopyga are nested within the genus Calliphora .  相似文献

The article is based on the author’s ethnographic fieldwork in the Czech Armed Forces (2001–2002) in which she focused on the process of military professionalization—a set of extensive institutional reforms initiated upon the Czech Republic’s accession to NATO. She shows that these reforms were not limited to the military sector and involved efforts on the part of the state officials and the media to change the position of the military in the public sphere and culture. The goal of these changes was to bring the image of seriousness to the discredited Czech military, a process that demanded the obliteration of the cultural idiom of Švejk—a literary hero of the 1920s novel by Jaroslav Hašek and the representation of a peaceful resistance to war and military violence. In the course of the twentieth century, Švejk has become one of the most pervasive cultural references of the popular laughter at oppressive military power and has been a leading cultural idiom for the Czechs during the 30 years of German and Soviet military occupations. The article shows how the current official efforts at changing the image of the Czech military focus on the obliteration of Švejk’s cultural idiom, bringing him so frequently to the public discourse that they produce a phantom-like effect in which Švejk has come to haunt the process directed at his expurgation. The established cultural idiom of skepticism toward the army and military bureaucracy thus challenges the transition from communism to democracy and questions the reliance on military force, the imagery of violent conflicts, and just wars as necessary tools of politics.  相似文献

CP 47,497, a potent cannabinoid receptor type 1 agonist, is the main active ingredient in the herbal mixture “Spice” sold in European countries. The illegal use of “Spice” for its psychoactive effects has become a social issue. In this study, the in vitro metabolism of CP 47,497 was investigated in human liver microsomes to characterize the metabolic fate of CP 47,497. CP 47,497 was incubated with human liver microsomes, and the reaction mixture was analyzed using liquid chromatography‐tandem mass spectrometry. A total of eight metabolites were detected in human liver microsomes and structurally characterized based on mass spectral data. The main metabolic pathways involved hydroxylations or oxygenations. The identified metabolites were mono‐oxygenated metabolites (M1 and M4), mono‐hydroxylated metabolites (M3, M5, M6, M7, and M8), and a di‐oxygenated metabolite (M2). The detection of these metabolites could confirm the presence of CP 47,497 in biological samples; therefore, collectively, they would be excellent indicators of “Spice” drug abuse.  相似文献

This article represents a contribution to the debate over the Europeanization of political parties, one of the hot topics in contemporary political science. It explores the extent of Europeanization in political parties represented in the lower chamber of the Parliament of the Czech Republic by means of an analysis of party election manifestoes. The extent of Europeanization in these documents is analyzed using a bi-dimensional conceptualization. The first we call the quantitative dimension, assesses the space taken by the topic of European integration in each manifesto. The second one we call the qualitative dimension. This, using the analysis of content, measures the degree to which the European integration issue is elaborated in the programs. Using this conceptualization, we analyze the election manifestoes of five Czech political parties in the period 1996–2006.  相似文献

5-Methoxy-N,N-diisopropyltryptamine (5-MeO-DIPT) is a designer hallucinogen derived from tryptamine and is reportedly abused and involved in criminal activities. For the detection of 5-MeO-DIPT use, a liquid chromatography-tandem mass spectrometric method for 5-MeO-DIPT and its metabolites, 5-hydroxy-N,N-diisopropyltryptamine (5-OH-DIPT) and 5-methoxy-N,N-isopropyltryptamine (5-MeO-IPT) was developed and validated in rat urine. The urine samples were pretreated by protein precipitation with acetonitrile and introduced into a BDS HYPERSIL C(18) column (50 × 2.0 mm, 5 μm) for chromatographic separation. Mobile phases consisted of methanol, water, and 1% formic acid, and gradient elution was used at a flow rate of 0.2 mL/min. For the MS detection, multiple-reaction monitoring analysis was adopted. The linear range was 0.01-10 μg/mL, and the lower limit of quantification was 10 ng/mL for all analytes. The intra- and interday accuracies and precisions met the criteria (<15%). The developed method was successfully applied to the drug-treated rat urine.  相似文献

Anti-American, pro-Chinese sentiment is spreading widely in South Korea. This phenomenon is caused by extreme US-ROK policy dissension over matters related to North Korea, especially the nuclear questions, and South Korea's emotional attachment for China based on historical and geopolitical factors. In order to prevent this irrational situation from damaging the mutual interests of both Washington and Seoul, the two capitals should come up with mutually acceptable options for nuclear issues—placing more gravity and priority on dialogue over sanctions as a matter of strategy. Coercive measures can be employed only as a last resort. In order to maintain peace, to fulfill the political responsibility as a great power in East Asia, and to reciprocate to South Korea's positive expectation, Beijing should play a more constructive role in resolving the North Korean nuclear issues and in inducing Pyongyang to open up and reform more aggressively.  相似文献

Children’s empathy and prosocial behavior play an important role in their social competence. Of the influential factors, research has demonstrated that parental behaviors and the quality of the parent–child relationship are important correlates of children’s development of empathy and prosocial behavior. The current study examined the associations between different types of parental behaviors (i.e., parental knowledge, parental solicitation, and parental psychological control), “balanced connectedness” in the parent–child relationship, which allows for both closeness and autonomy, and empathy and prosocial behavior in adolescents. The participants were 335 married couples (more than 80 % European American) and their adolescent child (49.0 % female; 10–13 years). Data were collected at three time points for parental behaviors, balanced parent–child connectedness, and adolescents’ empathy and prosocial behavior, respectively. The results of structural equation modeling suggested that adolescents’ perceptions of parental solicitation and parental psychological control may be associated with their empathy and prosocial behavior through their perceived balanced connectedness with parents. These findings suggest that enhancing balanced connectedness in the parent–child relationship may contribute to promoting empathy and prosocial behavior in adolescents over time. Further, this study suggests that parental solicitation may play a role in adolescents’ empathic and prosocial development, possibly depending on the quality of the parent–child relationship.  相似文献

Abstract: There are several areas within mitochondrial DNA that show length heteroplasmy. If the heteroplasmy pattern is unique and consistent for each person, it may be used to support an interpretation of exclusion in identity testing. We investigated whether the length heteroplasmy pattern would be consistent under different amplification conditions. We also determined whether various amplification parameters would affect the homopolymeric cytosine stretches (C‐stretch) in HV1. Monoclonal samples tended to be heteroplasmic after amplification. After several repetitions, C‐stretch patterns of all samples were inconsistent even under the same amplification conditions. Increased PCR cycles and high template concentrations resulted in a more frequent heteroplasmic tendency. These amplification parameters seem to have little effect if samples are not long enough in C‐stretch or total length of the segment from nt 16180 to nt 16193. It is suggested that the pattern of length heteroplasmy cannot be used as an additional polymorphic marker.  相似文献
