认同是国家利益的来源,从两个途径制约着国家的外交政策。以阿拉伯认同对伊拉克外交政策塑造为主线,伊拉克外交可以分为前萨达姆时期、萨达姆时期与后萨达姆时期三个阶段,在此三个阶段中,库尔德民族认同、伊斯兰宗教认同、逊尼派和什叶派的宗派认同对外交政策的影响力也同时存在。伊拉克国家认同缺失正是其外交政策导向多变的原因,重新构建强大的国家认同,在国家认同指导下展开自主的外交交往,是伊拉克消除内乱、提高国际信用度的可取出路。  相似文献

Direct PCR is fast becoming a popular method in forensic science due to the advantages of saving time and money in the lab while increasing the probability of obtaining substantial results has a positive rippling effect. A laboratory is able to reduce the time spent on processing trace DNA samples, which can lead to investigators receiving important information in a timely manner that may not have been possible using standard methods. This study highlights the benefits of direct PCR in forensic casework by analysing trace and touch DNA on a range of substrates and exploring the loss of initial DNA due to extraction.  相似文献

Direct PCR has been used successfully in wildlife forensic DNA analysis from several types of biological samples using specialized, commercial direct PCR kits. This is attributed to the proprietary chemicals provided in the kits such as pre-PCR buffer and modified DNA polymerases. These reagents can be expensive, thereby limiting their widespread adoption in developing countries, where wildlife crimes are often encountered. We report on a study to evaluate the possibility of using low-cost direct PCR assay for degraded and processed wildlife sample analysis. Phire® and Q5® polymerases were used, due to their relatively low cost, for direct amplification of six aged and processed sample types (dried skin, 30-year old hair, muscle tissue, bone, trace blood mixed in vodka, and dried soft antler). The result indicated that Phire® Hot Start II DNA polymerase and Q5® DNA polymerase performed similarly to commercially available direct PCR kit. The low-cost amplification could efficiently identify species origin from all aged and processed samples. We observed a rate of more than 80% amplification success and high PCR product concentrations sufficient for further sequencing. The assay proved to be cost effective and robust; thus, we expect it to be adopted by wildlife forensic laboratories in developing countries.  相似文献

The Asia policy of the Bush administration follows from two principles: its preference for ‘hub-and-spoke relationships’ led from Washington, and the restored priority of security issues over the mixture of trade interests and human rights that was the hallmark of the Clinton presidency. The initial focus of the administration on the restoration of political and strategic ties with old allies such as Japan, and on strategic competition, has been mitigated by another realistic approach: the need to seek new allies and partnerships. This policy was already evident towards India before September 11, 2001, but has been magnified with the onset of a coalition against terrorism, and almost as importantly, against the proliferation of weapons of mass destruction. The resumption of strategic and military ties with China, the priority of anti-terrorist cooperation over human rights issues with Southeast Asia, the increased support for India that is of more strategic value than America's tactical involvement with Pakistan, are developments that overshadow the US relationship with traditional allies such as Japan or the European Union. The major weakness of the Bush Asia policy, however, is its relative neglect of major economic and social issues in the region. Although support for some weakened ASEAN economies has increased, there is neither a more intense coordination of economic policies with Japan, in spite of initially declared intentions, nor a major economic and social strategy for Southeast and South Asia that would support the fight against terrorism.  相似文献

Abstract

This article analyses Macau's casinos as an example for accumulation by dispossession, in which they serve to transfer wealth from Mainland China to Macau and the casinos' foreign investors. They also represent a model for economic development and this model has migrated to Singapore, where it also operates as a form of accumulation by dispossession. By requiring citizens to pay an entrance fee, Singapore's casinos explicitly appropriate other people's money. The efficacy for the use of casinos as economic development is interrogated here because Macau's casino experience has emerged as a model for economic development in Asia beyond simply Singapore.  相似文献

This article addresses the important question of whether foreign direct investment enhances economic growth and labour productivity in Mexico, both from a theoretical and empirical perspective. After briefly reviewing the Mexican experience with net FDI inflows during the 1990s, the article presents a simple endogenous growth model which explicitly incorporates any positive (negative) externalities generated by additions to the foreign capital stock. Using cointegration analysis, the article estimates a dynamic labour productivity function for the 1960-95 period that includes the impact of the growth rate in the stocks of both private and foreign capital (as opposed to the flows) and the economically active population (EAP) (rather than the rate of population growth). The error correction model (ECM) estimates suggest that increases in both private ad (lagged) foreign investment spending, as well as the rate of growth in exports, have a positive and economically significant effect on the rate of labour productivity growth. In addition, the results show that increases in the EAP have a negative and statistically significant effect on the rate of labour productivity growth, while changes in the government consumption variable have a negative but marginally significant impact. The error correction terms of the estimated models are negative and statistically significant, thus suggesting that deviations of actual labour productivity growth from its long-run value are corrected in subsequent periods. Finally the article generates historical simulations from the estimated ECM's and offers some policy recommendations to enhance the positive externalities associated with FDI inflows.  相似文献

Abstract

European leaders frequently vaunt the European Union's distinctiveness in adopting and pursuing a comprehensive approach to security. The EU's profile as an international actor is designed to span across all dimensions of security. As a result, its security policy portfolio involves a large number of institutional actors and policies that need to be coordinated. The ambition of the EU to provide security in a comprehensive manner raises challenges at the politico–strategic level, at the level of operational and policy planning and in day-to-day implementation. So far, the field is lacking an inclusive analytical framework for the analysis of providing security through a distinctively comprehensive civil–military, economic and political organisation. This article seeks to close this gap by providing suggestions for how the wide range of issues related to comprehensive security could be structured, and by framing the matter theoretically and with reference to existing conceptual work and empirical research.  相似文献

Abstract

India's spectacular rise in recent years has been the source of hyperbolic theorising and speculation on its major power status. Middle power theory offers a set of dynamic analytical parameters which allow for re-evaluating India's global influence and identifying both strengths and weaknesses of its power projection and resources. Placing emphasis on themes of Third World leadership, good international citizenship, multilateral activism, bridge-building diplomacy, and coalition-building with like-minded states, the middle power concept can encapsulate key aspects of India's contemporary agency and account for structural dynamics which constitute a reformist world-view through the reconfiguration of the Indian state within the existing world order. Overall, middlepowermanship delineates fundamental continuities in India's foreign policy tradition, epitomises India's existing position in the neoliberal world order, while providing a good indication of the directions India will take on the global stage in the short and medium-term.  相似文献

The relationship between western multinational corporations' perceived commercial interests and democratic quality in developing markets is more varied than habitually argued. While autocratic policy making and low-intensity democracy have been judged to provide benefits to investors, they are also increasingly recognized to generate features prejudicial to commercial operations. Many investment trends reflect the adverse impact of democratic limitations in developing markets. Multinational companies can be faulted less for a uniform effort to frustrate democratic improvements than for a failure to develop a coherent or proactive engagement in relation to the international democracy promotion agenda.  相似文献

Existing scholarship about ballot measure voting and elite cuegivers suggests that the express endorsement of an unpopular legislature on a statewide ballot measure will depress voter support. Despite seven tests across two decades on both high- and low-profile measures, it did not. This null finding is in keeping with macro-level patterns of strong public support for the more than 4000 legislative referrals approved by voters in the past century. Consequently, we propose that the influence of an elite endorsement on voter behavior is more complicated than past research suggests. Specifically, in keeping with the seminal observation made by Hibbing and Theiss-Morse (1995) that American political cynicism is more a matter of distaste for certain political practices than for actual political institutions, we suspect that when voters are overwhelmed by policy proposals that are both unfamiliar and complex, they may find assurance in the imprimatur of their General Assembly.  相似文献
