Chinese Geographical Science 2011年第1期21卷 1-16页

作者： george C S LIN Department of Geography University of Hong Kong

History has brought us into a significant moment when the majority of the human kind has taken up resi-dence in urban settlements. The focus of global urbanization has shifted to the developing world and the center of manufacturing is no longer confined to the Global North. This paper provides a periodical assessment of the current status of China's urban transformation in the global context of a shifting emphasis of industrialization and urbaniza-tion. China's phenomenal urban transformation deserves a special attention not only because of its unparalleled scale and speed but also because of its distinct trajectory of growth that does not conform to normal theoretical ex-pectations. The results of assessment revealed an urban economy with remarkable hybridity, a society that is in-creasingly stratified, polarized, and segregated, and a juxtaposed urban space undergoing restless and pervasive transformation. A decentering world should entail a decentering knowledge production. A critical reflection upon the Chinese patterns and processes of urban transformation has identified 4 main issues with great potentials for inno-vative knowledge production, namely: 1) privatization and economic development; 2) state, society, and space; 3) urbanization of capital, labor, and land; and 4) the environment and Chinese political ecology. The paper closes with the remark that a rapidly transforming urban China has presented itself as a fertile and resourceful testing ground for critical and innovative geographic enquiries.

Earlier epidemiological studies identified diet as a primary environmental factorthat determines substantial differences in prostate cancer incidence and mortality between East Asian and West European soci- eties. New data from experiments performed in tissue culture and with animal models as well as epidemiological studies suggest that psychoemotional stress could be a second environmental component that influences prostate cancer progression by activation of epinephrine/beta（2）-adrenergic receptorsignaling in the tumor cells. The emerging information on the role of stress in prostate cancer progression provides an additional incentive to actively treat anxiety and depres- sion frequent psychogenic comorbidities of prostate cancer.

Wireless sensor networks (WSNs) are exposed to a variety of attacks. The quality and complexity of attacks are rising day by day. The proposed work aims at showing how the complexity of modern attacks is growing accordingly, leading to a similar rise in methods of resistance. Limitations in computational and battery power in sensor nodes are constraints on the diversity of security mechanisms. We must apply only suitable mechanisms to WSN where our approach was motivated by the application of an improved Feistel scheme. The modified accelerated-cipher design uses data-dependent permutations, and can be used for fast hardware, firmware, software and WSN encryption systems. The approach presented showed that ciphers using this approach are less likely to suffer intrusion of differential cryptanalysis than currently used popular WSN ciphers like DES, Camellia and so on.

A commercial product of carbon nano-particles, Cabot MONACH 1300 pigment black （CMPB）, was studied for basic structural information and electrochemical performance in neutral aqueous electrolytes, aiming at applications in supercapacitors. As confirmed by SEM and HRTEM, the CMPB had a hierarchical struc- ture, containing basic 10 nm nano-spheres which combined into ca. 50 nm agglomerates which further aggregated into larger particles of micrometres. The capacitance of this commercial material was found to increase with decreasing the size of hydrous cation （Li＋→Na＋ → K＋）, instead of the cation crystal radius （K＋→ Na＋→Li＋） when coupled with the same anion （cl-）. In electrolytes with the same cation concentration （K＋）, changing the anion from the larger dianion （SO42 ） to the smaller monoanion （cl-） also increased the capacitance at high potential scan rates （〉50 mV/s）. Increasing electrolyte concentration produced expected effect, including raising the electrode capacitance, but lowering the equivalent series resistance （ESR）, charge transfer resistance （CTR）, and the diffusion resistance. At higher temperatures, the CMPB exhibited slightly higher capacitance, which does not agree with the Gouy-Chapman theory on electric double layer （EDL）. A hypothesis is proposed to account for the capacitance increase with temperature as a result of the CMPB opening up some micro-pores for more ions to access in response to the temperature increase.
