A DIALECTICAL APPROACH TO RESEARCH AND DEVELOPMENT PLANNING

This paper reports on the methodology and an application of a dialectical approach to research and development, planning. The methodology features a structured debate followed by argumentation analysis. The argumentation analysis in turn is followed by an assessment of the plausibility of the arguments. The application involved using the methodology to assess the level of funding for research and development for a transportation system that would employ advanced technology. The Dialectic Inquiry process, and specifically, the plausibility rating activity, were seen as valuable aids for policy analysis.     

基于手机信令数据的长春市活动空间特征与社区分异研究

居民时空行为成为透视城市空间的重要视角,本文基于手机信令数据研究长春市活动空间及其社区分异,轮廓性的揭示居住空间、就业空间和消费休闲空间的分布规律,从人地互动的过程与格局的视角认识城市空间。研究发现,居住活动对中心城区依赖明显高于就业和消费休闲活动,就业活动呈现多中心连片发展格局,近郊的欧亚卖场和郊区的净月潭成为人们消费休闲活动的重要选择。就业-居住距离和消费休闲-居住距离的社区分异显著,折射出三类活动空间关系复杂,由此感知城市生活空间质量和社会空间结构。通过对社区分异的空间聚类分析明晰各地域自身问题,从而有针对性的对长春的空间调整优化和居民行为引导提出建议,构建和谐宜居的城市空间。     

Fluid mixing induced by hydrothermal activity in the ordovician carbonates in Tarim Basin,China

Permian hydrothermal activity in the Tarim Basin may have been responsible for the invasion of hot brines into Ordovician carbonate reservoirs. Studies have been undertaken to explain the origin and geochemical characteristics of the diagenetic fluid present during this hydrothermal event although there is no consensus on it. We present a genetic model resulting from the study of δ¹³C, δ¹⁸O, δ³⁴S, and ⁸⁷Sr/⁸⁶Sr isotope values and fluid inclusions (FIs) from fracture‐ and vug‐filling calcite, saddle dolomite, fluorite, barite, quartz, and anhydrite from Ordovician outcrops in northwest (NW) Tarim Basin and subsurface cores in Central Tarim Basin. The presence of hydrothermal fluid was confirmed by minerals with fluid inclusion homogenization temperatures being >10°C higher than the paleo‐formation burial temperatures both in the NW Tarim and in the Central Tarim areas. The mixing of hot (>200°C), high‐salinity (>24 wt% NaCl), ⁸⁷Sr‐rich (up to 0.7104) hydrothermal fluid with cool (60–100°C), low‐salinity (0 to 3.5 wt% NaCl), also ⁸⁷Sr‐rich (up to 0.7010) meteoric water in the Ordovician unit was supported by the salinity of fluid inclusions, and δ¹³C, δ¹⁸O, and ⁸⁷Sr/⁸⁶Sr isotopic values of the diagenetic minerals. Up‐migrated hydrothermal fluids from the deeper Cambrian strata may have contributed to the hot brine with high sulfate concentrations which promoted thermochemical sulfate reduction (TSR) in the Ordovician, resulting in the formation of ¹²C‐rich (δ¹³C as low as ?13.8‰) calcite and ³⁴S‐rich (δ³⁴S values from 21.4‰ to 29.7‰) H₂S, pyrite, and elemental sulfur. Hydrothermal fluid mixing with fresh water in Ordovician strata in Tarim Basin was facilitated by deep‐seated faults and up‐reaching faults due to the pervasive Permian magmatic activity. Collectively, fluid mixing, hydrothermal dolomitization, TSR, and faulting may have locally dissolved the host carbonates and increased the reservoir porosity and permeability, which has significant implications for hydrocarbon exploration.     

China’s Evolving Policy towards the Democratic People’s Republic of Korea under Xi Jinping

Despite international pressure to condemn North Korea (DPRK), China’s successive leaderships have dealt carefully with Pyongyang, especially vis-à-vis its nuclear weapons program. This moderate stance reflects the two countries’ decades-long relationship, summarised in the Chinese idiom that Pyongyang and Beijing are “as close as lips and teeth”. Nevertheless, the DPRK’s third nuclear test in February 2013 raised enormous challenges for the new Xi Jinping leadership to maintain the previous DPRK policy focused on the status quo and stability on the Korean Peninsula. China’s attitudes and policies towards the DPRK after the provocative third test signified a possible reorientation of Beijing’s DPRK policy. This generated repercussions in the countries concerned and prompted debates among experts. This article asks how these events should be understood and what their implications are for the Xi leadership’s policy on the DPRK, the stability of the Korean Peninsula, and Northeast Asia. Given China’s competitive relations with other major powers, we conclude that the Xi leadership will not abandon the DPRK; indeed it will reinforce the policy of strengthening China’s influence over it. Nonetheless one aspect of doing so will involve China opening up to other – cooperative, multilateral – approaches to reinforcing stability on the Korean Peninsula and in Northeast Asia.
