张海霞︱致 IEEE 主席：赞学术界回归常识 2019 年 6 月 3 日 【题记】今天上午收到 IEEE 主席 José M. F. Moura 的来信 “IEEE 解除对编辑和同行评审活动的限制 ” ，赞赏 IEEE 的勇气，很高兴学术界回归常识。谢谢所有朋友的关心和支持，今后我会继续支持 IEEE 的各项工作，致力于推动学术的独立和自由发展，很荣幸和骄傲与你们同行！ Dear Prof. José M. F. Moura, Cc to Prof. Toshio Fukuta, Prof. Lombardi Fabrizio, and Prof. Gianluca Piazza, I am so glad to get your email with subject “A message from the IEEE President: IEEE Lifts Restrictions on Editorial and Peer Review Activities”. This is the best news I ever heard from May 29th after I send out my open letters. Thanks for all your efforts to Lift Restrictions on Editorial and Peer Review Activities from IEEE under this special time period with outside pressure and insider resistance. This is a moment, we, Academic community, should be proud for our fight to keep the Independence and Freedom of Academic. As I mentioned in my statement, I will come back to IEEE NANO and IEEE JEMS editorial board until one day it comes back to our common professional integrity. Now, it is time to re-join the team and contribute my efforts with enthusiasm as usual. Let’s work together to make IEEE, an international academic community, great again. Haixia Zhang, Professor, Peking University June 3rd, 2019 附： IEEE 主席的来信 Dear Haixia Zhang, Last week the U.S. government issued export controls on Huawei Technologies Ltd and 68 of its affiliated companies. In response, IEEE issued guidance on actions required to comply with these controls. We acted promptly because we wanted to protect our volunteers and members from potential legal risk that could have involved significant penalties. As a non-political, not-for-profit organization registered in New York, IEEE must comply with its legal obligations under the laws of the United States and other jurisdictions. We also engaged the U.S. government to seek clarification on the extent to which these export control restrictions were applicable to IEEE activities.I am pleased to report that this engagement was successful and we have revised our guidance to remove any restriction on the participation of the employees of these companies as editors or peer reviewers in the IEEE publication process. To reemphasize, all IEEE members can continue to participate in the open and public activities of the IEEE, including our scientific and technical publications.Many members expressed apprehension with respect to IEEE’s initial guidance and its impact on editors and peer reviewers based on their employer affiliation. I understand the concern this raised for many of you and appreciate the feedback that IEEE leaders and I received.As an international organization operating in 160 countries, IEEE supports the free and open exchange of scholarly and academic work and the global advancement of science and technology. IEEE is committed to enabling an environment of international cooperation and the sharing of our members’ wealth of knowledge to drive innovation.We appreciate the patience of our members and volunteers as we worked through a legally complex situation. If you have any comments, questions, or concerns, please contact me atpresident@ieee.org.For more information, please visit www.ieee.org . Thank you for supporting IEEE in our mission to advance technology for humanity. José M. F. Moura2019 IEEE President and CEO
因变量与次要影响因子之间的拟合结果是怎样的？ 假设某个因变量 Y 与三个自变量 X 1 、 X 2 、 X 3 的 三元线性拟合公式 高度正相关（相关系数 R 大于 90% ），并且知道自变量 X 1 是 主要影响因子（权重大约占 60%~70% ） ，其它两个自变量 X 2 、 X 3 都是 次要影响因子 （请特别注意 主次有别！ ），那么，采用 Excel 多元回归现成的命令，由电脑进行因变量 Y 与次要影响因子 X 2 或者 X 3 的 一元线性回归分析 ，得到的结果是不是相关判定系数 R 2 不太理想而 Significance F 比较理想？其理由是 X 2 和 X 3 的的确确是因变量 Y 的影响因子，但不是主要影响因子。 如果以上判断（观点）不完全正确，因变量 Y 与次要影响因子 X 2 或者 X 3 的 一元线性拟合 的相关判定系数 R 2 和 Significance F 都有比较理想的可能，那需要什么条件？也就是说，什么条件下因变量与次要影响因子一元拟合的效果比较好？什么条件下因变量与次要影响因子一元拟合的效果不好？ 由电脑进行因变量 Y 与两个次要影响因子 X 2 和 X 3 的 二元线性回归分析 ，相关判定系数 R 2 有可能比较理想吗？两个自变量的 P-value 有可能都比较理想吗（ P-value 越小越好、一般要求小于 0.05 ）？拟合得到的结果是不是相关判定系数 R 2 不理想、两个自变量或者其中一个自变量的 P-value 也不理想？其理由是自变量 X 2 和 X 3 都是次要影响因子，二元线性回归拟合公式中没有主要影响因子。 （请专家特别是数理统计专家、气象专家、水利专家赐教）
