“反思的现代性”与“全球风险社会”——乌·贝克风险社会理论的马克思主义批判

乌·贝克有感于当代社会中似乎日趋严重的风险问题，提出了用“反思的现代性”理论来审视西方的现代化过程，比较客观地评价了资本主义工业化的历史功过，揭示了现代性内在矛盾及其在全球风险社会中新的表现形式，对当代的“全球主义”民族利益至上的价值观进行了抨击。贝克的反思现代性理论具有现实性和历史感。     

Beyond Materialism: A Coevolutionary Reinterpretation of the Environmental Crisis

Materialism, both as a vision of the good life and as a cosmological basis underlying epistemology and modern science, drives humanity's environmental crisis. The dominant thrust of the environmental movement has been simply to shift to a longer slower materialism. Understanding how materialism creates our environmental problems and limits our vision of the good life is a necessary step toward creating a different future. Understanding development as a process of coevolution between knowledge, technology, social organization, values, and nature provides an alternative cosmological and epistemological framing which both gives us perspective on materialism and suggests an alternative vision for the future.     

The Paradox of Competition in the World of Volatility

Abstract

This paper analyses the mechanism in which fashion is produced, marketed, and consumed from the viewpoints of the consumption and supply-side, in the midst of an increasingly complex meaning of fashion and dress in modernity. The focus of the study is a theoretical account of the paradoxical consequences of market orientation and supply chain management in the middle market of international fashion retailing in the light of the idiosyncrasy of the restraints that are innately embedded in the fashion industry. The result gleaned from this study has an implication for an alternative approach of market orientation in international fashion retailing especially in the industrial economies.     

现代化进程中价值理性反思的问题意识与原因探析

从价值理性概念的全面界定出发,评析当下世界现代化进程中现代性理念的发展史,可以看出,现代性的历史展开过程是一个工具理性不断膨胀、价值理性不断失落的过程。放眼世界,立足于中国,从理论和实践两个方面全面分析价值理性失落的原因,为重建价值理性奠定理论前提。     

Measuring the Pace of Technological Progress: Implications for Technological Forecasting

The pace of technological progress is a construct that has evolved from technological change theories. Although the construct is well described, it lacks a valid objective measure. Measuring the pace of technological progress is believed to be important for both technology management and technology forecasting. A newly-developed objective measure of the pace of technological progress called the Technology Cycle Time indicator (TCT) is evaluated. The TCT indicator was used in two comparison analyses: (1) assessing the pace of progress of superconductor and semiconductor technologies; and (2) assessing the position of various countries patenting in the semiconductor technology field. The TCT assessments were then analytically compared with specialist assessments found in the literature. The findings revealed that the TCT provided a valid assessment in each situation. The TCT has important implications for technology management and technology forecasting research.     

现代性与俄罗斯的“反乌托邦”文学——以扎米亚京的《我们》为中心

20世纪初,在俄罗斯兴起的＂反乌托邦＂文学,是对人类延续了千年之久的＂乌托邦＂梦想的解构与颠覆。它的出现,既是＂现代化＂发展的结果,又是对＂现代化＂的反思,在批判＂现代化＂危害的同时,更有对＂现代化＂特征的复归,这一点,在＂反乌托邦＂文学著作《我们》中体现的尤为明显。     

液相色谱法同时测定防晒霜中16种紫外线吸收剂

建立了同时检测防晒霜中16种紫外线吸收剂含量的高效液相色谱分析方法。样品用甲醇、四氢呋喃、高纯水、高氯酸的混合溶液溶解后超声提取。采用新型ZORBAXSBC18（5tam,250μm×4．6mmi．d．）色谱柱,以甲醇、四氢呋喃、高氯酸水溶液（V／V／V）（pH2．6）梯度洗脱,检测波长311nm。结果显示在22min内16种紫外线吸收利完全分离,在10-4000μg／mL范围内呈线性关系,相关系数大于0．9990;方法定量限为0．02％-0．4％;在市售防晒霜中加标回收率为84．0％．113．9％,相对标准偏差为2．49％．5．75％。本方法简便准确,能够满足进出口检验的需要。

Short-term market reaction after extreme price changes of liquid stocks

In our empirical study we examine the dynamics of the price evolution of liquid stocks after experiencing a large intra-day price change, using data from the NYSE and the NASDAQ. We find a significant reversal for both intra-day price decreases and increases. Volatility, volume and, in the case of the NYSE, the bid–ask spread, which increase sharply at the event, stay significantly high days afterwards. The decay of the volatility follows a power law in accordance with the `Omori law'. While on the NYSE the large widening of the bid–ask spread eliminates most of the profits that can be achieved by an outside investor, on the NASDAQ the bid–ask spread stays almost constant, yielding significant short-term profits. The results thus give an insight into the size and speed of the realization of an excess return for providing liquidity in a turbulent market.     

The demand of liquid assets with uncertain lumpy expenditures

We consider an inventory model for a liquid asset where the per-period net expenditures have two components: one that is frequent and small and another that is infrequent and large. We give a theoretical characterization of the optimal management of liquid asset as well as of the implied observable statistics. We use our characterization to interpret some aspects of households' currency management in Austria, as well as the management of demand deposits by a large sample of Italian investors.
