Service transformation—managing a shift from business travel to virtual meetings

It has been shown that the potential for environmental, and financial improvements through the increased substitution of in-person meetings by virtual communication is considerable. However, it has also been shown that this potential is not automatically realized by investing in the technology that can enable virtual meetings. This paper describes two case studies that explored the factors that influenced communication and meeting behavior. A number of drivers and barriers for virtual meetings are identified, and, in addition, measures are proposed to improve the utilization of virtual tools for business communication.     

Spontaneous abortion after transcervical chorionic villus sampling: A case report

A case of spontaneous abortion after transcervical CVS is presented. Despite no evidence of bacteria in the vagina and cervix prior to sampling and the prophylactic use of Metronidazole, pathological evidence of chorioamnionitis was found. The implications of this are discussed.     

碳酸锶废水对生态环境的影响调查及治理方案

碳酸锶因电子工业飞速发展而身价百倍，但其生产废水的直接排放则造成了严重的环境污染，本文通过对水体、农业、渔业、人体健康和水生生物等多种因素调查，掌握了碳酸锶废水污染成因，同时提出了资源再利用方案。     

抚顺市空气可吸入颗粒物特征的研究

于2002年1～7月份在抚顺市区四个点位采集了环境空气中的可吸入颗粒物样品，经分析后获得了可吸入颗粒物组分的时间分布和空间分布特征，即采暖期PM10样品中有机碳（OC）、元素碳（EC）的绝对含量和相对含量均高于非采暖期，工业区PM10样品中的Fe、Zn、Pb的绝对含量和相对含量均明显高于其它点位，反映了其工业区的特点。     

Genetically Modified (GM) Crops: Precautionary Science and Conflicts of Interests

Risk governance of GM plants and GMfood products is presently subject to heatedscientific and public controversies. Scientistsand representatives of the biotechnologyindustry have dominated debates concerningsafety issues. The public is suspicious withregard to the motives of scientists, companies,and political institutions involved. Thedilemmas posed are nested, embracing valuequestions, scientific uncertainty, andcontextual issues. The obvious lack of data andinsufficient information concerning ecologicaleffects call for application of thePrecautionary Principle (PP). There are,however, divergent opinions among scientistsabout the relevance of putative hazards,definition of potential ``adverse effects,' andwhether actions should be taken to preventharm. The reliance on the concept ofsubstantial equivalence in safety evaluation ofGM food is equally controversial. Consequently,value assumptions embedded in a scientificframework may be a barrier for employment ofthe PP. One of our major conclusions is thatprecautionary GMP usage requires riskassessment criteria yet undeveloped, as well asbroader and more long-term conceptions of risk,uncertainty, and ignorance. Conflicts ofinterest and public participation are otherissues that need to be taken intoconsideration. GMP governance regimes that arejustifiable from a precautionary and ethicalpoint of view must transcend traditionalscientific boundaries to include alternativescientific perspectives as well as publicinvolvement.

关于制定连云港市水土保持生态建设规划的思考

连云港市地处欧亚大陆桥的东桥头堡,是沿海十四个开放城市之一,国家定位是将其建设成为连接太平洋沿岸与中亚地区的国际商贸中心和全国性的旅游城市。而目前的山丘区水土流失严重,植被稀少,生态环境恶化,与国家定位目标和连云港市发展目标相差甚远。因此在制定水土保持生态环境建设规划时,必须紧紧围绕改善生态环境这条主线,以增加农民收入和改善生存条件为突破口,因地制宜,坚持长期综合治理,方能实现“山川秀美”之目标。     

活性污泥吸附重金属Cr6+的研究

以活性污泥为材料，采用不同时间、温度、pH进行吸附重金属Cr^6 的研究。实验结果表明，当吸附时间为15min，吸附温度为28℃，吸附pH=7时具有较好吸附效果。在此条件下，当重金属Cr^6 浓度为50mg/L，其吸附率可达97．2％。
