整合的效果：学习内容不再是你的工作内容

中国远程教育 2013年第6期 100-102页

作者： rick wilson 季瑞芳(译) 不详北京开放大学

大多数人已经意识到了将组织内部的“学习内容”和其他“内容”整合的重要性。有的人已经开始全力应对这种变化给自己所在组织带来的影响，而另一些人则正在创新或改变自己的学习技术以适应内容整合带来的变化。

加州海啸地球科学家与联邦、州和地方政府应急管理人员密切合作来帮助沿海社区防范海啸发生前、海啸过程中、海啸发生后产生的潜在影响。对于远程海啸,来自美国国家海洋和大气管理局(National Oceanic and At mospheric Administration,简称NOAA)西海岸和阿拉斯加海啸预警中心的科学信息(预测模型、浪高、首波到达时间等)是可以利用的。加州应急管理人员必须以简洁明了的方式将海啸信息传达给最终安排在他们的管辖区采取适当应急措施的地方官员。在2009年9月29日萨摩亚海啸预警中,来自加州地质调查局和洪堡州立大学(Humboldt State University)的地球科学家在海啸来临之前为加州应急管理处在与美国国家海洋和大气管理局与其他州和地方应急管理人员进行的远程会议的信息传输方面提供了技术支持。加州地球科学家收集了一些附加的背景资料用于预测美国国家海洋和大气管理局预测模型所没有覆盖到的地区的潮汐条件和浪高。在应急响应过程中,加州地球科学家的参与明确了哪些地区处于危险中,哪些地区遭受海啸袭击的风险低。加州地球科学家参与未来海啸应急响应的行动包括以下方面:与美国国家海洋和大气管理局密切合作来简化其海啸警报信息的传递流程并扩展其预测模型的覆盖面;②为地方应急管理人员制作包括已经存在的海啸的情景资料,作为每次海啸事件的参考;③建立一个州级信息共享中心和一支海啸前应急响应队,以协助地方官员一起观测和报道海啸的影响。

In this issue of Cellular&Molecular Immunology,Hou and coworkers provide novel insights into glucocorticoid(GC)treatment refractoriness in immune thrombocytopenia(ITP),reporting that myeloid-derived suppressor cells(MDSCs)contribute to GC resistance in ITP via impairments in their glucocorticoid receptor(GR)expression and mitochondrial metabolism[1].

Journal of Iron and Steel Research International 2018年第2期25卷 133-145页

作者： Sunday Abraham rick Bodnar Justin Raines Yufeng Wang SSAB Americas Muscatine IA 52761 USA

Although a great deal of research has been done in the area of inclusion control during steelmaking, a complete description of the process of inclusion modification and shape control cannot be found in literatures. As a result, the terms ＂inclusion modification＂ and ＂shape control＂ are often used loosely in the technical community. To utilize the full potential offered by a calcium treatment, it is important to understand why an inclusion whose composition has been modified may not necessarily have its shape modified. With the purpose of decoupling the process of inclusion phase change from inclusion shape control, and to provide a complete description of the metallurgy of calcium treatment, a detailed literature survey has been performed on the subject. By coupling the survey with a new concept developed to tailor the cleanliness of steels to the intended applications, the hope is to provide the reader with valuable information on calcium treatment for inclusion modification and shape control.
