Although many scholars of Central and Eastern Europe politics write about the relative weaknesses of civil societies, some studies delivered evidence of cases where interest groups were able to influence particular decisions and policies. Therefore, we aimed at identifying and examining the most influential national interest groups of eight different policy areas in post-communist Hungary hoping to explore the reasons for their success. Older generations of organisations benefit from political embeddedness, while newer advocacy groups rely more on legal instruments and public mobilisation. The operation of successful groups has not been affected by the strong political polarisation of the Hungarian party system.  相似文献

The regulatory regionalism approach has increasingly claimed that a new mode of regional governance is emerging globally. Regional policy regimes, developed in broad social and economic territorial areas, affect the internal transformation of the state. The authors plan to provide comprehensive empirical evidence about the emergence of worldwide regulatory regionalism by identifying how regulatory agencies have diffused very successfully within the regional level in recent decades. The paper aims to identify, using an original methodological design, the ways in which such diffusion of agencies occurred, as this may have theoretical relevance for the study of regulatory regionalism. The authors' hypothesis suggests that transnational political interactions in each regional cluster triggered agency diffusion, contributing to the development of the regulatory state within the countries of each region. To test this hypothesis, the authors employed a data set of regulatory agencies including the OECD (Organisation for Economic Co-operation and Development), and most Asian and Latin American countries (+59) from 1950 to 2007, for 15 sectors related to finance, risks, utility and competition. Bayesian data analysis was used to estimate the parameters of interest.  相似文献

DNA is one of the fastest growing tools in forensic sciences, increasing reliability in forensic reports and judgments. The use of DNA has increased in different areas of the forensic sciences, such as investigation of plant species, where plastid DNA has been used to elucidate and generate evidence in cases of traceability of genetically modified and controlled plants. Even with several advances and the practice of using DNA in forensic investigations, there are just few studies related to the identification of genetic tools for the characterization of drug and nondrug-types of Cannabis. Herein, the whole plastomes of two drug-type Cannabis are presented and have their structures compared with other Cannabis plastomes deposited in the GenBank, focusing in the forensic use of plastome sequences. The plastomes of Cannabis sativa “Brazuka” and of the hybrid Cannabis AK Royal Automatic presented general structure that does not differs from the reported for other C. sativa cultivars. A phylogenomic analyses grouped C. sativa “Brazuka” with the nondrug C. sativa cultivars, while the hybrid Cannabis AK Royal Automatic placed isolated, basal to this group. This suggests that the analysis of plastomes is useful toward genetic identification of hybrids in relation to C. sativa.  相似文献

Postmortem magnetic resonance imaging (MRI) is rarely used for the radiologic assessment of gunshot injuries, although it has clear advantages over postmortem computed tomography (CT) with regard to the imaging of soft tissue injuries. Another benefit in using MRI is that lodged projectiles composed of nonferromagnetic material such as lead present only marginal metal artifacts compared with severe artifacts on CT. This case report presents CT and MRI findings in a case with two gunshot wounds to the neck: a perforating wound and a nonperforating wound with a lead bullet lodged in the cervical spine. The decedent underwent CT and MRI before the scheduled autopsy. A ring of radiopaque material under the dermis in the fatty tissue was identified at both entrance wounds on CT, which was indicative of contact shots. The perforating gunshot was clearly indicated on CT by bullet fragments along the wound channel through the perforated 6th cervical vertebra and the fractured cricoid cartilage at the exit wound. The second trajectory, however, was only assumed based on the presence of gunshot residues at the entrance wound and the position of the lodged bullet. The radiologic assessment was severely impeded by the metal artifacts on CT. Barely noticeable metal artifacts on MRI allowed for clear visualization of the soft tissue injuries and the ruptured medulla oblongata. Only MRI clarified the soft tissue injuries of the brainstem noninvasively, which could provide specific and graphic information on the rapidity of death and the incapacitation of the victim.  相似文献

Minutiae are small distinguishing features found along every ridge flow, which make each friction ridge print unique. The most common friction ridge prints found at the crime scene are fingerprints; therefore, the most of the minutiae studies are focused exactly on this kind of prints. The authors believe that further examination and enlargement of the palm print database could result in better use of the palm prints for personal identification. We analyzed a total of 160 palm prints from 40 females and 40 males aged between 18 and 70 years from Slovakia. For the evaluation of the minutiae, the area of the hypothenar had to be marked out. The classification of the minutiae used for this study was based on a modified version of the classification system using the total of 13 types of minutiae. The frequency of every minutiae type was calculated and, using the chi-square test with Yates's correction, bilateral and sex differences were assessed. The relationship between the different types of minutiae was examined with Pearson's correlation test. During the initial phases of the identification process, the focus should be on the least common types of minutiae (Y or M and return), which were found not to correlate; thus, their mutual occurrence is random (e.g., overlap—Y or M, crossbar—return, or Y or M—dock). The results of the present study show which specific minutiae types are the most suitable for personal identification. These findings may be beneficial in more effective outcome of the identification process.  相似文献

This paper examines Irish campaigns for condom access in the early 1990s. Against the backdrop of the AIDS crisis, activists campaigned against a law which would not allow condoms to be sold from ordinary commercial spaces or vending machines, and restricted sale to young people. Advancing a conception of ‘transformative illegality’, we show that illegal action was fundamental to the eventual legalisation of commercial condom sale. However, rather than foregrounding illegal condom sale as a mode of spectacular direct action, we show that tactics of illegal sale in the 1990s built on 20 years of everyday illegal sale within the Irish family planning movement. Everyday illegal sale was a long-term world-making practice, which gradually transformed condoms’ legal meanings, eventually enabling new forms of provocative and irreverent protest. Condoms ‘became legal’ when the state recognised modes of condom sale, gradually built up over many years and publicised in direct action and in the courts.  相似文献

This paper examines gender aspects of tactics of the alter-globalization movement. Focusing mainly on two transnational collective actions in Prague in 2000 and in Genoa in 2001, the research draws on participant observation, interviews with activists and analysis of the movement's alternative media. The feminist activism within the movement, the gendered tactics and their representation in the alternative media are analysed using the concept of diffusion. Although feminists are involved in the protests, and local Czech feminist activism was incited by the international mobilizations in Prague in 2000, they are often marginalized because of the emphasis on masculine confrontational and violent tactics used in demonstrations. The movement's alternative media further reproduce gender stereotypes. The visual representations of the tactics are traditionally gendered – women are depicted as fairies, men as fighters; this is because the movement does not want to appear weak and feminine, and seeks to be effective.  相似文献

This article argues that Donald Trump’s Asian strategy hardly marks a radical transformation from Barack Obama’s ‘pivot to Asia’. This is because the ‘pivot to Asia’ never really existed. Although Obama was successful in building legitimacy for the strategy through international norms, he failed to translate his lofty rhetoric into practice. Much of his original pivot components (building a constructive relationship with China, coordinating with Asian allies and multilateralism in the Association of South East Asian Nations and the Trans-Pacific Partnership) has either failed or did not live up to expectations. Donald Trump was adamant that the Asian pivot was a bad strategy and that he would not follow it. But although he completely discarded Obama’s legitimization of the rebalance (as Trump speaks pragmatically and does not care about international norms), in actuality he has followed many of Obama’s policies, and even improved on some of them. That being said, Trump’s ‘pivot actions’ appear to be erratic, pragmatic short-term actions rather than a meticulously planned long-term strategy similar to Obama’s rebalance (which did not materialize). Thus, while Obama failed to transform the pivot into an effective strategy, neither is Trump’s effectiveness backed by a coherent Asian strategy.  相似文献
