The relative and absolute age of roller and gel ink entries determined by gas chromatography (GC) and UV-vis methods are presented in this paper. The relative age of ink entries is concluded by the comparison of solvent amount between questioned and known dated entries. Absolute age of ink entries is estimated through the changing ratio of solvent components between heated and unheated samples without known samples for comparison. The methods are accurate and reliable. 相似文献
Policy experimentation has been widely considered a ‘magic bullet’ of policy improvement and key to economic prosperity in China. This article, however, argues that policy experimentation in China does not always seek policy efficiency. Rather, it can be manipulated as a political symbol without actually affecting practices. By taking a case study on Wenzhou's financial reform, this article illustrates that local policy experimentation can serve as a mechanism for the central government to legitimately delay reform practices—in the case of Wenzhou's financial reform in 2012, out of a desire to maintain socio-economic stability during the power succession at the 18th Party Congress. In this reform, socio-economic stability was deemed more important than developing a sustainable and effective long-term policy. This article provides a new perspective on understanding policy experimentation in China by proposing the idea of ‘symbolic reforms’. 相似文献
This article investigates the escalation of US-China trade disputes and the implications for Sino-US relations. Both structural realism and liberal institutionalism have failed to pay sufficient attention to the evolution of the US-China economic relationship, and this article strives to highlight this crucial issue. The article employs a historical perspective to examine the transformation of US-China economic relations in the twenty-first century. It argues that the US-China economic relationship is evolving from a symbiotic but asymmetric one between 2001 and 2008, toward an increasingly competitive one after the 2008 global financial crisis, especially in the Trump-Xi era. The changing dynamics of US-China economic relations, as well as the shifting perceptions of the top leadership of each country toward the other, create the impetus for the transformation of Sino-US relations. This article suggests that the recent trade tension is embedded in the growing strategic competition between the two countries.
AbstractChina’s massive ‘Belt and Road Initiative’ (BRI) – designed to build infrastructure and coordinate policymaking across Eurasia and eastern Africa – is widely seen as a clearly-defined, top-down ‘grand strategy’, reflecting Beijing’s growing ambition to reshape, or even dominate, regional and international order. This article argues that this view is mistaken. Foregrounding transformations in the Chinese party-state that shape China’s foreign policy-making, it shows that, rather than being a coherent, geopolitically-driven grand strategy, BRI is an extremely loose, indeterminate scheme, driven primarily by competing domestic interests, particularly state capitalist interests, whose struggle for power and resources are already shaping BRI’s design and implementation. This will generate outcomes that often diverge from top leaders’ intentions and may even undermine key foreign policy goals. 相似文献
