China's Dilemma on Iran: between energy security and a responsible rising power

As international pressure on China's policy concerning its increasing investments in Iran grows, the Chinese leadership has to painfully balance its impulse toward energy and economic cooperation with Iran against other important interests, including enhancing its image as a responsible big country. After analyzing the evolution of China–Iran energy relations, this paper tries to answer the question of how China has responded to the intensification of US-led sanctions against Iran, what merits and shortcomings China's attempts to balance or reconcile its interests in Iran might create, and what options China can take to deal with a possible oil crisis.     

公共价值的研究路径与前沿问题

自20世纪90年代公共价值被公共行政学者正式提出之后,对其研究就没有间断。近几年来,公共价值逐步成为公共行政学界研究的热点问题,但公共价值研究的统一话语体系并没有形成。回顾公共价值研究意在对公共价值的基础概念和研究脉络进行梳理,并深化公共价值对于公共行政研究重要性的认识。从研究文献中公共价值概念的分析入手,在区别定义结果主导的公共价值(PV)和共识主导的公共价值(PVs)基础上,明确了公共价值研究的不同路径,并分别对公共价值研究的主要内容进行了梳理和阐述,为理解现有文献中公共价值概念的不同内涵提供了思路,也为进一步深化公共价值的研究提供了概念框架和逻辑基础。公共价值是公共行政研究的基础性问题,未来公共价值研究的关键领域主要包括,公共价值的内容和创造机制的实证研究、公共价值的冲突管理问题研究。同时,公共价值研究也对革新政府治理模式具有启示意义,在中国情境下具有一定的应用价值。     

Will or Won’t the RMB-Greenb Rate Dip Below 6?

THE Renminbi entered 2013 with gusto, the spot Yuan/US$ rate hitting 6.2216-strongest since China’s 2005 exchange reform and also a 19-year high. This market hotspot might presage a rate lower than the RMB 6 benchmark.The exchange rate reflects the exter-     

试析乌克兰与俄罗斯关系中的经济因素

本文的主题是从经济关系的角度分析乌克兰与俄罗斯关系的变化.苏联解体后,两国经济联系逐渐弱化,由深度相互依赖的经济关系逐渐演化为正常的国家经济关系.乌克兰与俄罗斯关系中的议题日益多样化,与经济利益相关的一系列议题取代政治关系和军事斗争成为两国关系的主轴.尽管仍然存在安全和政治问题,经济因素已经逐渐成为影响两国关系未来发展的重要指标和稳定器.     

基因距离、隐性知识与跨国知识流动

知识的有效传播和创造需要同时掌握显性知识和隐性知识。“知识螺旋”(SECI)模型阐述了隐性知识与显性知识之间的相互转化,提示相近的基因距离能有效促进隐性知识的传播,从而促进跨国知识流动。基于45个国家在1987—2006年期间的专利互引情况的研究表明：在控制了地理距离、语言和宗教等因素后,基因距离这一生物学特征仍然显著阻碍着跨国知识流动;基因距离的阻碍作用在地理距离较小、共同语言和共同宗教的国家间更强;跨国知识流动能解释基因距离对收入差异影响的50%。因此,国家之间的深层次差异仍然阻碍着隐性知识的传播。我国需要加强国际间人才流动、支持出国留学、扩大学术交流、利用开放网络改革教育方式等措施,促进隐性知识传播,减少跨国知识流动的障碍。     

八味芪丹胶囊联合依帕司他治疗2型糖尿病周围神经病变临床观察

目的 观察八味芪丹胶囊联合依帕司他治疗2型糖尿病周围神经病变的临床疗效及对患者血清铁蛋白及氧化应激指标的影响,探讨其可能的作用机制.方法 将62例糖尿病周围神经病变(diabetic peripher-al neuropathy,DPN)患者随机分成观察组和对照组,每组31例.两组均以个体化降糖为基础治疗,对照组另口服依帕司他,观察组在对照组疗法的基础上加用八味芪丹胶囊,疗程均为4周.分别采用中医证候评分、多伦多临床评分系统(Toronto clinical scoring system,TCSS)评定临床疗效,采用神经电检诊仪检测神经传导速度,采用化学比色法检测血清铁蛋白(serum ferritsn,SF),硫代巴比妥酸法检测丙二醛(malondial-dehyde,MDA)水平,化学发光法检测超氧化物歧化酶(superoxide dismutase,SOD)水平.结果 治疗后两组患者中医证候评分、TCSS评分均较治疗前明显减少(P<0.05),且观察组减少程度大于对照组(P<0.05).治疗后两组患者神经传导速度均较治疗前明显提高(P<0.05),且观察组较对照组提高更为明显(P<0.05).治疗后两组患者血清SF、MDA水平均较治疗前明显降低(P<0.05),SOD水平明显升高(P<0.05);且观察组SF、MDA水平的降低程度以及SOD水平的升高程度均大于对照组(P<0.05).结论 八味芪丹胶囊联合依帕司他治疗2型糖尿病周围神经病变的疗效优于单用依帕司他,且能有效提高神经传导速度,其机制可能与调节铁代谢途径、改善氧化应激反应有关.

Portable high‐resolution automated 3D imaging for footwear and tire impression capture

The forensic science community raised the need for improved evidence recognition, collection, and visualization analytical instrumentation for field and laboratory use. While the 3D optical techniques for imaging static objects have been extensively studied, there is still a major gap between current knowledge and collecting high‐quality footwear and tire impression evidence. Among optical means for 3D imaging, digital fringe projection (DFP) techniques reconstruct 3D shape from phase information, achieving camera‐pixel spatial resolution. This paper presents a high‐resolution 3D imaging technology using DFP techniques dedicated to footwear and tire impression capture. We developed fully automated software algorithms and a graphical user interface (GUI) that allow anyone without training to operate for high‐quality 3D data capture. We performed accuracy evaluations and comparisons comparing with the commercial high‐end 3D scanner and carried out qualitative tests for various impressions comparing with the current practices. Overall, our technology achieves similar levels of accuracy and resolution with a high‐end commercially available 3D scanner, while having the merits of being (1) more affordable; (2) much easier to operate; and (3) more robust. Compared with the current practice of casting, our technology demonstrates its superiority because it (1) is non‐destructive; (2) collects more evidence detail than casts, especially when an impression is fragile; (3) requires less time and money to collect each piece of evidence; and (4) results in a digital file that can easily be shared with other examiners.     

Railway Sector Reform in China: controversy and problems

The railway sector in China has undergone several major rounds of reform and institutional restructuring since 1986. These reform initiatives have largely been unsuccessful due to strong resistance from vested interest groups. The development of China's railway sector has raised some challenging issues that include the centralization of power in the Ministry of Railways (MOR), state monopoly control, rampant corruption and the accumulation of a huge debt burden. The 2013 railway reform initiatives have provided very little in the way of concrete measures to deal with these thorny issues but have instead created more controversy and problems in an already crisis-ridden sector. For the railway industry, the transformation from the mixed-function MOR to a monopolistic China Railway Corporation (CRC) will not necessarily lead to better railway management.
