跨国企业社会责任履行塑造着企业形象,不仅会影响当地员工对企业的认知,并可能将这种认知进一步泛化到企业母国。文章使用“海外中国企业与员工综合调查(OCEES)”数据库,以东南亚中资企业当地员工为样本,利用线性回归模型来分析企业社会责任中的慈善责任与文化责任对当地员工对华认知上的影响。中资企业在东南亚国家履行企业社会责任时,仅仅通过对当地社区进行慈善捐赠并不能显著促进当地员工对中国的积极认知,也不能显著提升他们对中国影响力的正面评价,需要企业充分了解和尊重当地的宗教信仰和风俗习惯,即履行文化责任来拉近双方文化距离,才能让当地员工对中国有更加正面的认知,也更加正面地理解中国的影响力。

FY-4A/GIIRS(Geostationary Interferometric Infrared Sounder)首次实现了地球静止轨道红外高光谱探测,可以连续获得高垂直分辨率的大气温度和湿度廓线信息。当GIIRS视场内有云存在时,目前Level 2业务大气温湿度垂直廓线产品只提供观测视场内云顶以上高度的温度廓线,且不反演整个视场的湿度廓线。基于GIIRS辐射观测值用U-Net卷积神经网络算法实现了全天空大气温湿度廓线反演,包括晴空和全云覆盖视场,同时利用常规无线电探空观测资料对反演精度进行了检验。结果表明:U-Net算法有云视场的温湿度廓线反演能力与晴空相当,且夏季温度反演精度优于冬季,有利于灾害性天气多发季节的监测。在云系较活跃的夏季,随着视场内云量的增加温度廓线反演精度逐渐变高,表明该算法适用于有云时大气温度廓线反演,而湿度随着云量的增加反演均方根误差RMSE增大。视场内不同云光学厚度时温度反演误差相差不大,RMSE均在2.5 K左右,平均偏差ME在1 K以内,对流层高层薄云时反演误差相对而言较小。湿度反演随着云光学厚度的增大反演误差也增大,说明对于一定程度的薄云,GIIRS能够获得不错的反演精度。虽然U-Net算法物理意义不明确,但是能够快速实现全天空大气温湿度廓线反演,尤其在有云时能够获得更高的反演精度。

Objective: The objective of this study was to explore the safety, efficacy, economy, and other aspects of frequently-used antitumor Chinese patent medicine injections through a comprehensive evaluation of evidence-based medical research to provide scientific information and decision-making basis for drug selection, rational drug use, public awareness of safe drug use, and medical insurance. Materials and Methods: The names of five frequently used antitumor Chinese patent medicine injections were used as search terms, including the compound Sophora flavescens injection, Kangai injection, Aidi injection, Kanglaite injection, and Brucea javanica oil emulsion injection. Relevant evidence-based medical research was extracted from the databases. A descriptive evaluation was conducted, and the Markov model was used for the cost-benefit analysis. Finally, the above injections are ranked by comprehensive scores using the multi-criteria decision analysis and Delphi method. Results: The five injections had their own advantages in enhancing the effectiveness of anti-tumor treatments, improving the quality of life for cancer patients, and reducing the incidence of adverse reactions. From the perspective of economy and other attributes, compound S. flavescens was superior to B. javanica oil, Aidi, Kangai, and Kanglaite. After a comprehensive evaluation of the above five injections, the compound S. flavescens injection received the highest score. Conclusions: Compound S. flavescens, Kangai, Aidi, B. javanica oil, and Kanglaite have their own advantages in effectiveness and no significant difference in safety. Compound S. flavescens injection has the highest comprehensive score. Clinical attention should be paid to monitoring the initial stage of medication and special groups.
