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

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

Abstract

Despite shared historical experience and cultural proximity, the Visegrad group (V4) struggles to institutionalise its cooperation through stable mechanisms ensuring internal cohesion and external credibility. This is especially evident in the field of security and defence, which requires a shared strategic vision, in particular, common norms regarding the legitimate use of military force. While in the 1990s the four countries exhibited solidarity and unity in their collective ambition under the narrative of the ‘Return to Europe’, their general perception of security threats and strategic culture prevents deeper integration into a security community.  相似文献

The pandemic of Covid-19 has exposed the veins of inequality in Latin America. With a socioeconomic disaster looming, social emergency policies seemed inevitable. Yet while governments argue over the continuity of such policies and whether the fiscal rules in place should be respected, no sustainable response has come out. This essay problematises whether the pandemic could represent a critical juncture to forge ahead with political narratives that highlight tax exemptions and privileges enjoyed by the rich. We analyse the mitigation measures adopted by Argentina, Brazil, Chile and Uruguay and their repercussions on the debate surrounding progressive tax reforms to fund social schemes.  相似文献

This paper draws on recent research examining feminist and everyday geopolitics to focus on the relatively neglected domestic sphere as a space where geopolitical events like the Falklands/Malvinas war are learnt, (re)produced, remembered and contested by young people. It presents qualitative data drawn from interviews with young people from Argentina (Río Gallegos) and the Falkland Islands (Stanley), locations with intimate connections to the 1982 war. It argues that research in domestic environments that engages the familial relations, objects and practices that embody geopolitical pasts can help make sense of how young people (are able to) express geopolitical agency.  相似文献
