“休”──一个起源于远古的美学观念

一个出现于远古时代的审美观念──“休”及其美学内涵值得引起学界的关注。从《尚书》、《周易》、《诗经》用“休”，可知其与“美”字有相近或相同之义，《庄子》以“无为”释“休”而阐述其美的意蕴，“休”字构成了若干有美感意味的话语，如“休光”、“休畅”、“休美”等。魏晋以后，“休”的美感意味向“闲”转移。

论老子的管理哲学

老子哲学崇尚"自然",所谓"自然"就是自是、就是自在。这是他的世界观、人生观、价值观,也是他的人性论。在"自然"的意义上,有"上善若水""自胜者强"的人格追求。而"无为而治"是其管理的最高境界。

Identification of activity stop locations in GPS trajectories by density-based clustering method combined with support vector machines

The identification of activity locations in con- tinuous GPS trajectories is an essential preliminary step in obtaining person trip data and for activity-based trans- portation demand forecasting. In this research, a two-step methodology for identifying activity stop locations is pro- posed. In the first step, an improved density-based spatial clustering of applications with noise （DBSCAN） algorithm identifies stop points and moving points; then in the second step, the support vector machines （SVMs） method distin- guishes activity stops from non-activity stops among the identified stop points. A time sequence constraint and a direction change constraint are applied as improvements to DBSCAN （yielding an improved algorithm known as C-DBSCAN）. Then three major features are extracted for use in the SVMs method： stop duration, mean distance to the centroid of a cluster of points at a stop location, and the shorter of distances from current location to home and to the workplace. The proposed methodology was tested using GPS data collected from mobile phones in the Nagoya area of Japan. The C-DBSCAN algorithm achieves an accuracy of 90 % in identifying stop points in the first step, while the SVMs method is 96 % accurate in distin- guishing the locations of activity stops from non-activity stops in the second step. Compared to other variants of DBSCAN used to identify activity locations from GPS trajectories, this two-step method is generally superior.

Studies of Ce(Ⅲ)-ALC-F Interacting with Herring Sperm DNA by Electrochemical, Fluorimetric and UV-spectrophotometric Method

Ce(Ⅲ)-ALC-F complex can react with hsDNA to form an electrochemically non-active supermolecular complex Ce(Ⅲ)-ALC-F-DNA in the buffer solution of (CH2)6N4(pH=4.9), which results in the decrease of the peak current of Ce(Ⅲ)-ALC-F. This method can be applied to determine DNA concentration. In addition, by using fluorimetric and UV-spectrophotometric methods with studies of denatured DNA and the effect of NaCl solution , it is also found that the binding mode is intercalation.

A Comparative Study of Taoist and Heideggerian Concepts of Nature From Perspectives of Technology and Deep Ecology

With the theory of existentialism, hermeneutics and phenomenology, this paper carries out profound exploration in a comparative study of Heidegger and Taoist＇s concept of nature and the significance of understanding it. It not only plays an important role in comparison and analogy of eastern culture and western culture in the aspect of civilization and cultural communication, but also helps to take advantage of their theories to support the environmental-friendly movement. Moreover, the text also investigates some controversy in this field and how to solve the problems as well as the meaning of solutions. Both of the theories are significant for deep ecology for their opposing modern technology＇s generally reductionistic and materialistic view of nature.

Seismogram Analysis and Fitting of Three Earthquakes,West Papua,Recorded at Stations ENH and KMI,China

The S wave velocity structure of the earth below Eastern Southeast Asia has been investigated by analyzing the seismogram from surface wave to multiple depth waves in the time domain and three Cartesian components simultaneously.The wave passes across the front area of subduction zone between the Philippine plate and the Asian plate.The main data are waveform comparisons,instead of the arrival times.The synthetic seismogram is calculated using the GEMINI method.The synthetic seismogram constructed by PREMAN global earth model deviates greatly from the measured one.To solve this problem,corrections are needed for the β speed structure.Corrections cover the gradient change of β_h,which turns from negative to positive in upper mantle layers as in the PREMAN,change of earth crust depth and change of zero order coefficients of β velocity function in all earth mantle layers.So,the fitting is obtained,as well as the arrival time or the waveform of Love and Rayleigh surface waves,the S wave and the repetitive depth waves ScS_2 and ScS_3.This result reveals that the Southeast Asia,being stretched due to tectonic release,has a mantle in some parts with negative anomaly of S wave velocity and vertical anisotropy in all earth mantle layers.

任自然而忘是非——郭象政治哲学再思

郭象的政治哲学不是由理想状态出发对现实政治进行的规范性劝诫,而是基于其性分论的形而上学对统治的正当性进行的辩护。统治者决断的依据不在是非而在于自然,出于自然的行为就其本质而言仍然符合无为的要求。郭象以此为统治者政治统治的合法性提供了辩护。
