全球增暖对自然灾害的可能影响

近年来，气候对环境的影响已受到全球科学家越来越多的重视，中国是一个有１１亿人口的大国，生态环境较为脆弱，全球变暖将严重影响我国社会与经济生活的各个方面。本文初步研究了全球变暖对自然灾害的可能影响。结果表明，在大气ＣＯ２含量加倍的情况下，全球变暖将可能导致暴雨频度和洪涝风险增加，西北干旱趋势仍将延续；森林火灾、台风、滑坡与泥石泫灾害可能加剧；农林病虫害危害增加，范围扩大。同时，全球变暖导致的海平面上     

Starch- polyvinyl alcohol crosslinked film— performance and biodegradation

Starch-PVOH cast films were prepared with and without crosslinking agent (hexamethoxymethylmelamine) in the absence of plasticizer. Moisture absorption in films without crosslinking agent at a low relative humidity was similar to that of PVOH and increased as the relative humidity increased. Films with crosslinking agent showed moisture absorption linearly proportional to the relative humidity. Significant improvement in resistance to water disintegration for crosslinked starch-PVOH films was observed. While the tensile strength decreased with increased relative humidity, crosslinking significantly improved the tensile strength. Increased PVOH content improved elongation of films even when the relative humidity was 80% or higher. Biodegradation studies revealed that the degradation rate was negatively correlated with the PVOH content in films and crosslinking generated more converged degradation curves.

Cultural and individual differences in self‐rating behavior: an extension and refinement of the cultural relativity hypothesis

This study examined the relationships between culture, individual attributes, and self‐rating behavior among 1,786 university students in Canada, Hong Kong, Taiwan, mainland China, and Japan, and in doing so extended and refined the cultural relativity hypothesis. It explored the difference between vertical and horizontal individualists in self‐rating behavior, and examined the mediating effects of two individual attributes, self‐enhancement propensity and general self‐efficacy in the relationship between individualism and self‐rating behavior. The results confirmed that individualism is the cultural driver for self‐rating leniency, and that the individual‐level assessment of individualism is a stronger predictor of self‐rating leniency than are culture‐level differences. Vertical individualism was found to be positively related to self‐enhancement propensity, which in turn was positively related to self‐rating. Whereas, horizontal individualism was positively related to general self‐efficacy, which in turn had a positive relationship with self‐rating. We discuss the implications of the results for academic research and practical management. Copyright © 2006 John Wiley & Sons, Ltd.     

各地招退工过程中的行政控制立法比较

用人单位在招退工过程中,作为劳动保障部门的行政控制权究竟处于什么样的水平才是合适的,这一直是各地司法实践中所关注的问题.由于我国《劳动法》对这一问题没有作出明确规定,使得我国地方立法有了较大的空间.
