基于偏好度与竞争态的中国区域外资利用研究

将偏好度和竞争态模型引入外资利用研究中,并据此对2000和2009年中国24个地区的外资利用情况进行实证研究,结论为：1）偏好度和竞争态是一种有效分析区域外资利用变化趋势和特征的方法,能更全面地把握外资来源地的时空结构及其演变特征,建立合理的区域外资来源地结构体系;2）各地外资偏好度和竞争态结构基本健全,类型分布和成员组成虽不理想但日趋合理,区域外资利用总体呈“欧洲偏爱北方、亚洲偏爱南方”特征,外资引进重心长期稳定于香港、日本、新加坡、台湾等亚太或毗邻地区,地缘作用影响显著,近年向欧洲和美洲集聚,尤其是美国,但不同地区外资竞争态和偏好度各类型内成员分化显著,且同一地区内不同外资来源地的偏好度和竞争态差异悬殊;3）2000年以来中国区域外资偏好度普遍下降,尤其是东部和西部,各类偏好度和竞争态的成员数量变化剧烈,且偏好度类别演替和竞争态转移现象显著,尤其是强偏好和金牛及明星引资地;4）外资竞争态和偏好度及其变化的相关性不显著,西部尤其是西北地区被边缘化,港澳台对外资利用贡献差异明显,香港最优而澳门最差;5）外资引进目标地分类及其战略选择为优势稳定型——收获性和开拓性：战略、优势增长型——开拓性和扩张性战略、优势下降型——选择性战略、劣势稳定型——选择性和撤退性战略。     

基于自适应非稳态相位校正的时频域多尺度全波形反演

本文提出非稳态相位校正时频域目标函数,通过缩小观测数据与模拟数据在波形相位上的差异来缓解全波形反演过程中对应波形匹配错位的问题（周波跳跃）.同时引入自适应相位校正因子,可以根据观测数据与模拟数据的差异来调整相位校正量的大小.在构建非稳态相位校正时频域全波形反演目标函数的基础上,利用链式法则详细推导了对应的伴随震源,并从理论上证明了该方法的可行性与优越性.数值测试过程中结合了低通滤波多尺度反演策略,进一步缓解全波形反演过程中的强非线性问题.缺失低频分量测试结果表明,利用自适应非稳态相位校正时频域多尺度全波形反演方法结合常规全波形反演方法在缺失7 Hz以下低频分量的地震数据中仍然能够得到高精度的反演结果.震源不准确测试结果表明,即使震源子波相位差异较大,利用非稳态相位校正方法仍然能够一定程度上缓解周波跳跃现象.测试结果综合证明了本文提出的方法在构建初始速度建模,缓解周波跳跃等方面具有一定的优势.

     

The stamp of neoliberalism on the UK tonnage tax and the implications for British seafaring

In 2000 the UK adopted a tonnage tax strategy on ships and related businesses as the main strategy for revitalising its declining shipping industry. In line with EU policy on shipping, UK registered shipping companies were offered fiscal incentives based on reduced corporation taxes while labour was offered support for training. Almost a decade since the introduction of the tax it is clear that the strategy has delivered for business but not for labour. This paper considers the nature and limits of state intervention per se in declining economic sectors in the context of globalisation and a neoliberal approach to governance. It concludes that the problem is often not state intervention but rather the form of intervention, namely one that panders to, and is constrained by, neoliberalism.

The emerging Islamic State: Terror,territoriality, and the agenda of social transformation

The world has recently been witness to the emergence of a new contemporary geopolitical phenomenon: the declaration of Islamic States by specific Islamic organizations. This phenomenon has the potential to dramatically transform the geopolitical setting of the Middle East and to have farreaching effects on a global level. Of these most prominent, however, has undoubtedly been the June 2014 declaration by the “Islamic State” organization of a “caliphate” covering large areas of the two war-torn states of Syria and Iraq. The aim of this article is to interrogate the territorial aspects of the Islamic State and to discern what makes it unique and exceptional in comparison to the many other Islamic political organizations that have emerged in recent years. In order to facilitate a better understanding of territoriality, I distinguish here between two major dimensions: conceptions of territoriality and tactics of territoriality. My working assumption is that by distinguishing between conceptions and tactics of territoriality, we can compare the exercise of territoriality by states and, in the present case, organizations. In this article, I argue that the Islamic State poses a challenge to both the conceptual and tactical dimensions of the contemporary territory and territoriality of modern states. Yet, while its conception of territoriality may be widely shared by other political Islamic organizations, its uniqueness lies in its tactics and strategies. Indeed, it is the brutal tactics of the Islamic State that are less acceptable to many Muslims around the world, not its political conception, which enjoys considerable support in the Muslim arena. Yet, when comparing it with modern states, the Islamic State poses a challenge to the territory and territoriality in both conception and tactics.     

Informality and the state’s ambivalence in the regulation of street vending in transforming Guangzhou,China

Street vending faces uncertain state responses in contemporary Chinese cities, though it plays an important role in sustaining the livelihood of urban migrants. Building on the critical perspective that understands informality as a production of the state, this paper explores the nature of the regulation of street vending in Guangzhou since 1949. The state’s regulatory practices are characterized by what we call historical ambivalence and geographical ambivalence, which refer to the inconsistency in policies, which fluctuate between soft and hard approaches over time, and the mix of contradictory regulatory measures applied in different urban spaces, respectively. Ambivalence is generated because the state addresses street vending in ways that attain the overarching objective of urban policies. In particular, the exclusion of street vendors in present-day China is not historically natural but driven and sustained by the government’s pursuit of a good city image favorable for attracting capital in the context of intensifying inter-urban competition. The definition of informality is not a neutral classification. Rather, declaring when and to what extent an informal practice is tolerable depends on what the state desires in a specific historical circumstance.     

Rethinking graduated citizenship: Contemporary public housing in Singapore

The ways in which citizenship and housing are implicated in states’ global city aspirations demonstrate significant path dependency and local contingency. This paper serves to broaden the literature that has been dominated by the Western neoliberal context. First, I argue that The Pinnacle@Duxton – a one-of-a-kind public housing project in Singapore – represents the developmental state’s attempt to graduate its homogeneous public housing landscape, providing for and subsidizing the aspirations of a segment of its increasingly affluent middle class to buy into the ideology of the global city. Second, I show how the graduation of public housing coupled with the exaggerated demand for such exclusive projects validates consumer preference pricing in contemporary public housing. This results in a geographical graduation of citizenship, where the bulk of the population is relegated to lesser options on the edges on the island, unable to fulfil their aspirations for global living. In so doing, I make two contributions to extant literature on housing and citizenship in the global city. One, graduating citizenship is not always a case of states realigning their relationship with their citizens to fit the terms of the market. Two, the denial of citizenship to the global city does not always manifest in terms of substantive rights. Appreciating the unique histories and ideologies underpinning housing policies in global cities is instrumental if the variegated meanings of global cities and the citizenships within are to be elucidated.

Testing and modeling of the state-dependent behaviors of rockfill material

Dense Tacheng rockfill material (TRM) exhibits strain softening and dilation during drained triaxial tests, and therefore, an adapted Rowe’s stress–dilatancy equation was proposed for TRM. This equation incorporates an internal state index related to the density and pressure, as well as the coefficient of particle breakage and rotation. The adapted Rowe’s stress–dilatancy equation indicates that the relationship between stress and dilatancy is not constant, but varies with density and pressure. This result is in agreement with TRM test data. A state-dependent model was established for TRM using generalized plasticity theory combined with the adapted Rowe’s stress–dilatancy equation. The model includes twelve constants calibrated using TRM test data from Group A, and this model was used to predict the strain softening and dilatancy behaviors of dense TRM. Furthermore, the model predictions were validated using test data from Group B. In summary, the model accurately represented the stress–strain and dilatancy behaviors of TRM over a wide range of densities and pressures.
