哈贝马斯与韦伯合理化理论之比较 总被引:2,自引:0,他引:2
哈贝马斯和韦伯的合理化理论是一脉相承的,但二者在世界图景假设、哲学基础、理论性质三方面部有所不同。韦伯立足于超验世界和经验世界的对立来建构其合理化理论,因此其哲学基础是意识哲学,建构的合理性是普遍真理的形式合理性。哈贝马斯的合理化理论的世界图景假设是经验世界内的系统和生活世界的对立,其哲学基础是语言哲学,建构的合理性是共识的交往合理性。 相似文献

Quantitative phase analysis (QPA) is helpful to determine the type attribute of the object because it could present the content of the constituents. QPA by Rietveld method requires neither measurement of calibration data nor the use of an internal standard; however, the approximate crystal structure of each phase in a mixture is necessary. In this study, 8 synthetic mixtures composed of potassium nitrate and sulfur were analyzed by Rietveld QPA method. The Rietveld refinement was accomplished with a material analysis using diffraction program and evaluated by three agreement indices. Results showed that Rietveld QPA yielded precise results, with errors generally less than 2.0% absolute. In addition, a criminal case which was broken successfully with the help of Rietveld QPA method was also introduced. This method will allow forensic investigators to acquire detailed information of the material evidence, which could point out the direction for case detection and court proceedings. 相似文献

Micro‐Raman spectroscopy was applied to forensic identification of pigments in paint chips and provided differentiation between paint samples. Sixty‐six blue automotive paint samples, 26 solid and 40 metallic were examined. It was found that the majority of the collected Raman spectra provided information about the pigments present. However, in some cases, fluorescence precluded pigment identification. Using laser excitation at longer wavelengths or pretreatment to effect photobleaching often resulted in reduced fluorescence, particularly for solid color samples, and allowed pigment identification. The examined samples were compared pairwise taking into account number, location, and intensity of absorption bands in their infrared spectra. The estimated discrimination power ranged from 97% for solid paint samples to 99% for metallic paint samples. 相似文献

The state-monopolised system of vegetable retail in socialist urban China has been transformed into a market-based system run by profit-driven actors. Publicly-owned wet markets not only declined in number after the state relegated its construction to market forces, but were also thoroughly privatised, becoming venues of capital accumulation for the market operators now controlling these properties. Self-employed migrant families replaced salaried state employees in the labour force. Governments' increased control over urban public space reduced the room for informal markets, exacerbating the scarcity of vegetable retail space. Fragmentation in the production and wholesale systems restricted modern supermarkets' ability to establish streamlined supply chains and made them less competitive than wet markets. The transformation of urban vegetable retail documented here shows both the advance that capital has made in re-shaping China's agrifood system and the constraints that China's socialist institutions impose on it. Shanghai's experience also shows that the relative competitiveness of various retail formats is shaped by the state's intervention in building market infrastructure and institutions. 相似文献

Sino‐US relations over the last 100 years have been heavily affected by the ideological and cultural traditions of both sides; but the impact of ideas on each other has by no means been an even interaction. At the turn of the century when China and the US encountered each other, their destinies took opposite trajectories. While the US saw its dream of national greatness fulfilled with the continuous rise of its national power, China witnessed the sharp downfall from the peak of its self‐perception as the great central kingdom. Ever since then, all progressive intellectuals and reformers took inspiration from western ideas of democracy and freedom, while struggling at the same time against oppression and exploitation by western powers. These two aspects constitute the basic aspirations of the Chinese nation as a whole, which was summed up as ‘anti‐feudalism and anti‐imperialism’. One of the basic urges of Americans of all sorts in dealing with China throughout the years was to influence, educate and change China to its like. However, in front of Chinese revolutionary movments with democratic rights as part of their aims, the US government policies more than often favored the conservative or reactionary rulers. Meanwhile, the development of China takes its own course beyond the control of the US. Yet, under different circumstances, neither side could help placing hopes on the other. As for rulers of different Chinese adminstrations, they wavered between seeking American support in China's economic development and diplomacy on the one hand, and fear and resentment of American cultural influence on the other. Anti‐communism entered the US foreign policy thinking ever since the Russian Revolution. But US relations with the Chinese Communist Party have not been hostile all the way through but have undergone twists and turns. The period of best relationship between the US and the PRC took place in the 1980s and underwent a sharp turn after the events of 1989. Leaving aside other factors, the age‐long cultural paradigm of unrealistic hopes on each other, hence drastic disappointment, played a certain role. At present, The mentality of the bulk of Chinese including young students have also undergone a great change from the pre‐1989 period. The admiration for the US has receded and a certain degree of resentment of American pressure on China is on the rise. The pursuit of a strong and prosperous China remains the common and deep‐rooted national aspiration prevailing among Chinese of all ages and social strata and in this they identify themselves more with the government vs. foreign pressure, whatever their views on other subjects. The ideological aspect of difficulties in Sino‐US relations is not likely to go away in the foreseeable future and much wisdom is needed to handle it properly. 相似文献

This study investigates the influences of the evaporation temperature and Mg2+ concentration on the crystallization of an ammonium sulfate mother liquor. Specifically, their effects on the solubility, metastable zone width, crystallization amount, average particle size, and coefficient of variation of ammonium sulfate are examined through the laser and evaporation crystallization methods. Results show that solubility increases and the metastable zone width narrows with an increase in the evaporation temperature. At an evaporation temperature of 338.15 K, the controllability of the crystallization process improves and explosive nucleation does not easily occur. In this case, crystals with large average particle sizes, regular morphologies, and high crystallinity are obtained. With an increase in the Mg2+ concentration in the solvent, solubility decreases. The added Mg2+ covers the active nucleation sites, thus hindering the nucleation of ammonium sulfate and widening the metastable zone width. At a Mg2+ concentration of 0.9 g L−1 or higher, Mg2+ covers the active surfaces of the grains. This inhibits normal crystal growth and hinders the nucleation and growth of ammonium sulfate crystals, so the crystallization amount of ammonium sulfate significantly reduces. 相似文献

由于各个国家不同的传统、价值观念、社会准则、风俗习惯等因素造成的文化差异在跨文化交际中形成了文化障碍从而导致交际的失败.跨文化交际的三大障碍包括:认识上的误区,刻板印象及民族中心主义,因此,以“入乡随俗”的观点进行跨文化交际可以更大程度地相互接近、沟通最后取得交际的成功. 相似文献
