煤矿人为事故发生可能性预测数学模型研究

研究发现，煤矿工人的冒险行为主要可以由生产条件、个人表现、工作状况及用工方式等影响因素预测，煤矿人为事故的发生可能性主要由煤矿工人的冒险行为表现预测。据此，便可建立预测煤矿人为事故发生可能性的数学模型

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.

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。

Decoupling task and relationship conflict: the role of intragroup emotional processing

The present paper focuses on the role of emotion in intragroup conflict processes. We propose that how group members handle emotion affects intragroup interactions and has implications for task and relationship conflict. Three types of variables—collective emotional intelligence, intragroup relational ties, and conflict‐relevant interactional norms—constrain negative emotionality and may determine whether task conflict results in damaging relationship conflict. The moderating influence of these variables is discussed, as are compositional issues associated with measuring them. Copyright © 2004 John Wiley & Sons, Ltd.
