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.     

Development of Layered Sediment Structure and its Effects on Pore Water Transport and Hyporheic Exchange

Hyporheic exchange is known to provide an important control on nutrient and contaminant fluxes across the stream-subsurface interface. Similar processes also mediate interfacial transport in other permeable sediments. Recent research has focused on understanding the mechanics of these exchange processes and improving estimation of exchange rates in natural systems. While the structure of sediment beds obviously influences pore water flow rates and patterns, little is known about the interplay of typical sedimentary structures, hyporheic exchange, and other transport processes in fluvial/alluvial sediments. Here we discuss several processes that contribute to local-scale sediment heterogeneity and present results that illustrate the interaction of overlying flow conditions, the development of sediment structure, pore water transport, and stream-subsurface exchange. Layered structures are shown to develop at several scales within sediment beds. Surface sampling is used to analyze the development of an armor layer in a sand-and-gravel bed, while innovative synchrotron-based X-ray microtomography is used to observe patterns of grain sorting within sand bedforms. We show that layered bed structures involving coarsening of the bed surface increase interfacial solute flux but produce an effective anisotropy that favors horizontal pore water transport while limiting vertical penetration.

美国自然灾害的社会学研究

研究起始美国著名地球科学家普瑞斯说过：无论何时何地发生破坏性大地震,美国整个社会和经济组织都能感受到它的巨大冲击。面对这种损失巨大、影响面广的地震灾害,美国政府在其减灾计划中,强调了必须采取强力措施,“加强对国民进行地震及其危险性教育,以减轻地震对家庭、社会和国家的影响”。     

ZJR型涂料的制备及特性研究

利用溶胶凝胶法制备TiO2光催化剂,使用磷酸氢二钠、十水合四硼酸钠和氢氧化镁等制备了阻燃体系料,复合后制成ZJR涂料。利用热分析仪分析纳米TiO2和阻燃体系复合的防火涂料的温度与热失率关系,并得到热重与微商热重曲线。550~650℃之间,失重率约为11%,ZJR涂料在400~600℃有较好的阻燃效果。该涂料对污染气体的光催化降解研究结果表明:光照60 m in后,对二氧化硫的降解率为90.40%,紫外光照40 m in后,甲醛气体降解率为68.98%。进一步添加聚乙二醇和银离子使涂料改性,使涂料光催化甲醛的活性分别提高了11%和14%,效果显著。

大型烧结厂房爆破拆除设计与施工

所爆厂房由主厂房、环冷、除尘器、抽风机房组成，建筑面积近2万m^2，最大标高为43．5m，东边主厂房与高架通廊连为一体，东南8．6m为高压变电所；南边1．8m为80m高烟囱，2．5m处为架空管道，地下和地表运料通廊东西贯穿厂房，周围环境复杂。提出了先爆环冷和除尘器再处理抽风机房，最后爆破主厂房的总体爆破方案，采用爆破切割技术分离主厂房保留部分及高架通廊。采用了原地坍塌、定向倒塌和折叠爆破技术和施工工艺。爆破达到了预期效果，可供类似工程参考。

城市绿地系统建设与城市减灾防灾

自然灾害往往给城市造成重大损失.在城市综合防灾减灾体系中,城市绿地系统占有十分重要的位置.城市绿地系统是城市规划和建设中的重要组成部分,它不仅具有美化城市环境、净化空气、平衡城市生态系统、为城市居民提供休憩游乐场所等作用,同时还具有防震、防火、防洪、减轻灾害的功能.从城市绿地的定义和分类人手,分析了城市绿地系统在城市综合防灾减灾中的作用,并通过介绍和分析日本防灾公园的规划建设,探讨了城市避灾绿地系统的规划方法.
