The impact of monetary liquidity on Chinese aluminum prices

By expanding Frankel and Rose's (2009) theoretical model to consider the interaction of commodity prices with both money liquidity and expectation formation, this paper empirically studies the long-run relationship and short-term dynamics between aluminum prices and money liquidity via Vector autoregressive (VAR) and Impulse Response Function methodologies. Our results show that: (1) a cointegration relationship between money liquidity and Chinese aluminum prices exists, and monetary liquidity positively significantly influences the price over long periods; (2) a structural change has been found during the 2008 Financial Crisis and the change of Chinese monetary policies; and (3) the negative impact of production capacity mechanism on aluminum prices coexists with the positive impact of financial asset returns mechanism, to allow for varied market expectations on aluminum prices within and outside China.     

试论中西文化中颜色词语的联想意义

汉英语言中表示各种不同颜色的词语很丰富.我们不仅要注意它们本身的基本含义,更要留心它们深广的象征意义,因为其象征意义在不同语言中往往有不同的特点,有些特点甚至构成了人们对颜色的崇尚和禁忌.这种不同文化间颜色象征意义的差异是由于各民族的文化历史背景和审美心理的不同而产生的,是在社会发展和历史沉淀中约定俗成的,是一种永久性的文化现象.     

中国特色的城市化问题

针对当前社会经济发展中 ,建设有中国特色的城市化问题 ,展开全方位、多视角的分析阐述。指出并纠正了认识上对城市化问题的种种误区。提出中国的城市化发展应该与国情国力、工业化发展形势相协调 ,过程应有序、健康。并认为 :(1)在相当大一段时期内 ,中国城市化水平以界定在5 0 %或 5 5 %为宜 ,而不应该盲目追求西方国家不同国情的高指标、高比例 ;(2 )对城市今后的发展规模应有一个合理限度 ,考虑人口、用地、环境的合理容量 ;(3)小城镇的发展要合理引导、分期分批、有重点地稳步发展 ;(4)乡村城镇化必须发展生态农业与生态工业 ,走集约化、专业化的道路。正确引导中国的城市化进程 ,把城市发展和农村、工业和农业、人口流动、产业政策、区域平衡、科技进步、外向型经济可持续发展等当作整体一盘棋来统筹制定总体战略     

珠江口水域中华白海豚微量元素含量分析

对珠江口水域12头中华白海豚体内10种微量元素(As、Ba、Cd、Co、Cr、Cu、Ni、Pb、Zn、Hg)的含量进行测量.分析结果显示:受试样品中Zn元素含量最高,Cu、Hg次之,Co、Cr、Ni含量最低;肝脏和肾脏中微量元素含量较高,其余各组织器官中的分布不尽相同.分析认为珠江口水域中华白海豚受到一定程度的As、Hg、Cd、Pb污染.

白菜腌制中硝酸盐及亚硝酸盐含量的变化研究

硝酸盐及亚硝酸盐都是对人体有害的物质。文章研究了白菜在腌制过程中硝酸盐及亚硝酸盐含量的动态变化,实验表明亚硝酸盐的形成与白菜的腌制时间、温度、腌制液盐浓度、糖浓度等因素有关;硝酸盐的积累是受白菜的品种以及外部因素比如肥料、光、水分、温度等综合影响,在腌制过程中部分硝酸盐与亚硝酸盐相互转化。实验结果:在12℃的温度下腌制30天以后食用白菜比较好,而且腌制白菜的食盐浓度在10%~15%之间,糖浓度在3%左右较佳。     

结构抗震的"形而上""形而下"之思辨及工程意义

"形而上"、"形而下"是中国古代哲学中的基本范畴之一.古人借此推演出很多指导人们生产和生活实践的重要思想,并取得一系列的成功.中国古代科学的发展曾遥遥领先世界数千年之久--在结构抗震性能上也是如此,这些都与华夏先贤的哲学思维不无关系.本文通过一些实例的对比,重点分析了古今建筑结构抗震哲学思想的一些异同,这些异同可以从"...     

2004～2009年我国典型陆地生态系统地下水硝态氮评价

利用中国生态系统研究网络（CERN）2004～2009年31个典型陆地生态系统38个浅层地下水井硝态氮（NO 3--N）的监测数据,评价我国典型陆地生态系统地下水NO 3--N污染状况.结果表明,农田（4.85 mg.L-1±0.42 mg.L-1）、绿洲农田（3.72mg.L-1±0.42 mg.L-1）、城市（3....     

Possible use of Lingula sp. (Phylum Brachiopoda) as a dissemination strategy to promote sustainable development in Fangchenggang mangrove,China

The economic marketability of a brachiopod, Lingula was studied at three coastal mangrove sites, specifically based on socioeconomic parameters from 10 villages that utilized Lingula along Pearl Bay, Beilun Estuary Marine Nature Reserve, China. The significantly highest density of Lingula was at Jiao Dong (48.2 ± 35.14 individual/m²) whereas the biomass of Lingula was highest (0.76 ± 0.22 g/individual) at Gui Lao Bu. The shell size of the largest specimen was still less than that in other references. The socioeconomic study of the population related to Lingula involved a small group, and no relationship could be determined among the parameters of age range, education level, occupation, and financial status. The total economic value (320,927.4 Yuan) was based on the value of consumption whereas the value from sales was very low as recorded from Shan Xin over a three-month season. Analysis of the results to determine strengths, weaknesses, opportunities, and threats was undertaken to identify the potential of Lingula sp. to be promoted and supported in the market as a novel source of income for the local community who are associated with mangrove resources; and also to examine its potential as a new food source for the rapidly growing population of China.
