Effects of Different Diets on the Dietary Attractability and Selectivity of Chinese Shrimp, Fenneropenaeus chinensis

Attractabilities of different diets and dietary selectivity of Chinese shrimp, Fenneropenaeus chinensis were studied through behavior observation and feeding experiment, respectively. The five diets used in the experiment are: Fish Flesh (FF), Shrimp Flesh (SF), Clam Foot (CF), Polychaete Worm (PW), and Formulated Diet (FD). No significant differences of attractability exist between any two different diets when every two natural diets or all five diets are provided simultaneously. On the other hand, significant differences of attractability exist between FD and every single natural diet when they are provided simultaneously. Results of behavioral observation indicate that natural diets are more attractive than FD. In feeding experiment, Chinese shrimp has distinct selectivity on different diets. It positively selects CF and PW, negatively selects FF and SF, and excludes FD absolutely. The results of the present studies indicate that the dietary selectivity of shrimp was based not only on the attractabilities of the diets, but also on the responses such as growth and food conversion.     

The city-text in post-communist Budapest: street names,memorials, and the politics of commemoration

As in most parts of Central and Eastern Europe, there is a tradition in Hungary of changing street names and memorials in the wake of major political transitions. This article focuses on the change of street names and memorials, i.e. the city-text, in Hungary’s political capital, Budapest, between 1985 and 2001. The city-text in Budapest became a locus of dispute between different political authorities, including the nation state, the metropolitan municipality, and the district, each bearing different political ideals during and after the fall of communism. Discursive changes in the post-communist city-text emerged expressing specific conceptions of national sovereignty, but the direction of the changes were debated. Different levels of administration in Budapest and Hungary had divergent visions of what the new discourse on national sovereignty should be. The changes, therefore, did not express a simple transition to an agreed-upon post-communist value system, but were the result of a symbolic struggle between different levels of administration over what should be commemorated in the city-text.     

Identifying China’s leading world city: a network approach

This paper reports our research on China’s world cities. Formal network analysis of air passenger linkages for recent years among China’s most populous cities and among many of the world’s largest cities allows us to identify the country’s leading world city from among the leading Mainland candidates, Beijing, Shanghai and Guangzhou. We theorize our findings about China’s world cities in relation to both global forces (and China’s increasing entanglement with them) and the policies and actions of the national state. We examine the national and global urban network through a longitudinal, two-level analysis of airline passenger travel for four time points between about 1990 and 2005. We show that Beijing was China’s leading world city at the beginning of the time period, a status it lost nationally in as early as 1995, and then globally 10 years later. On the other hand Shanghai became China’s leading world city, and it acquired this status first nationally in 2000, and then globally in 2005. The changing status of the Chinese capital corresponds to the country’s increasing involvement with the capitalist world economy. Shanghai’s ascendance as the leading world city in China may indicate that global forces have come to play an increasingly important role relative to that of the developmental state.

中国南极长城湾及附近海区1993/1994年夏季表层水样无机氮、磷酸盐的浓度及其分布状况

1993／1994年南极夏季对中国南极长城湾及附近海区表层海水四种营养盐浓度及其分布状况作了调查。结果表明，NH4－N、NO3－N、NO2－N及PO4－P的大致浓度分别是2．13、7．07、0．74和1．12μg·dm-3。一般来说，湾内高于湾外氮盐于12月份常出现高值。四种形态的无机盐类之最高、最低浓度出现的时间和站位不尽一致。∑N／P递减次序大致是12月，2月，1月。水温变化与NH4－N、PO4－P浓度和∑N／P的变化常较一致，而与NO2－N则常不一，一些站位上营养盐浓度偏低可能与浮游植物摄取有关。结果显示了调研海区的浅水内湾特征。浮游植物所需营养充分。该湾仍维持正常状态。     

The developmental characteristics and strategic ideas of urbanization in China

Since cities and towns are places where those nonagricultural industries are centralized, urbanization is greatly interrelated with industrialization and de-agriculturalization. By means of this kind of interrelationship, Chinese urbanization level may be estimated with the formulas: P1=I1/I0/u0, Pr = N1/N0/u0. The urbanization after the founding of the People's Republic of China can be divided into the following 5 stages: the stage at the out set of industrialization (1949-1957); the high-speed urbanization stage (1958-1960); the first counter-urbanization stage (1961-1965); the second counter-urbanization stage (1966-1976); and the high-speed urbanization stage (1978-now). The characteristics of Chinese urbanization are: the industrialization launched by the government; the simultaneous development of urbanization of cities and urbanization of rural areas; the quite low capability of urbanization to absorb nonagricultural labor force; the incoordinate development of cities, etc. Before establishing a     

中国大陆科学钻探工程主孔100～2000 m 放射性产热元素的垂向分布特征及其成因

地球内部放射性产热元素U、Th及K(HPE)含量如何随深度的变化而变化是固体地球科学中的一个重要参数,在限定地壳的热和流变学结构、地球化学、岩石和构造模型中起关键性的作用。对HPE深部分布的认识主要来自于对大型花岗岩岩基的研究及对地表热流值和产热率之间关系的模拟,对高压-超高压变质地体的HPE随深度的分布缺乏认识。在苏鲁超高压变质带中实施的中国大陆科学钻探工程届时将提供超过5km的岩心,为确定苏鲁超高压带的HPE结构提供了最好的机会。对CCSD的100～2000m岩心的732块样品详细的放射性产热元素含量的测试及现今产热率计算的初步结果表明:(1)花岗质片麻岩具有最高的产热率,平均为1665×10-11W/kg;(2)副片麻岩(变沉积岩)具有中等的产热率,为994×10-11W/kg;(3)金红石榴辉岩及石榴石橄榄岩具有最低的产热率,为17×10-11～20×10-11W/kg;(4)放射性产热元素的浓度及相应的产热率随岩性的变化而变化,呈现阶梯状的分布特征。产热率随深度的变化特征表明CCSD主孔中的HPE三明治结构。该结构可能代表着高压-超高压变质地体中的典型HPE结构,比大型花岗岩岩基的HPE结构更复杂,与传统的HPE指数衰减分布模式不吻合。CCSD主孔中所揭示的三明治式HPE结构是大陆被动陆缘中的基性及超基性岩、沉积岩及花岗岩在深
