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.     

Current status and research on E-waste issues in Asia

Rapid economic growth in Asia and the increasing transboundary movement of secondary resources will increasingly require both 3R endeavors (reduce, reuse, recycle) in each country and appropriate control of international material cycles. Recently, managing electrical and electronic waste (E-waste) has become an important target for domestic and international material cycles from the viewpoints of environmental preservation and resource utilization efficiency. To understand the current status of E-waste issues in the context of international material cycles and to discuss the future tasks related to achieving 3R in the region, we organized the National Institute for Environmental Studies (NIES) E-waste Workshop in December 2004. This article reviews past studies on E-waste and briefly describes the topics presented and discussions held at the workshop. The topics at the workshop included E-waste generation, recycling systems, international trade, and environmental impacts. In addition, we discussed various issues such as terminology, current environmental concerns, and possible solutions. Transboundary shipments of E-waste should be conducted taking into consideration the concept of sustainable development. The direction of future research and possible collaborations are also discussed.     

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.

溜砂坡的成灾机理与防治对策

溜砂坡足我国西部山区公路的主要地质灾害之一。由于对溜砂坡的形成发展机理认识不足，目前采用的治理措施不能很好地解决溜砂灾害，有些工程措施反而会加大灾害程度。通过对川藏公路沿线溜砂坡的调查研究，阐述了溜砂坡的最基本特性是其生长性，分析了溜砂坡的成灾机理和危害性特点，有针对性地提出了符合西部地区经济条件的溜砂坡防治措施。     

世界末日的瘟神:生物武器

何为生物武器生物武器它可能像电影中那样是一阵烟雾,或像新闻中说的是一包粉末,也可能是一群老鼠或苍蝇。病原体通过空气,食物甚至皮肤等渠道侵入人、畜体内,迅速或缓慢地致死,也可大规模毁伤农作物。生物武器通常又称为细菌武器或病毒武器,由生物战剂和投放工具两部分组成。其中, 生物战剂是生物武器的核心,是用于杀伤人和动物,或破坏农作物的致病微生物及其所产生的毒素。根据现代战争要求,能够作为生物武器的病毒战剂通常要具有致病性、传染性和易使用性等几个特征。
